Work At Underground Test Site A New Indicator Of Possible Strikes On Iran’s Pickaxe Mountain Bunker

10 September 2026 at 23:01

Work at a specialized underground weapons test site in New Mexico, contracted earlier this year, was linked to planning for a potential new operation targeting Iranian nuclear facilities, according to a report from CNN. The U.S. military has notably left Iran’s hardest-to-reach site under Pickaxe Mountain untouched so far, but President Donald Trump and other U.S. officials have been openly talking about striking it.

On February 27, the day before U.S. and Israeli forces launched their initial wave of strikes on Iran, the Pentagon’s Defense Threat Reduction Agency (DTRA) quietly announced it had awarded a sole-source deal to Pate Construction Co., Inc., for new construction at the so-called Alternate Seismic Hardrock in Situ Test (ALT-SHIST) site. The work was needed to support an upcoming classified live-fire test. ALT-SHIST is situated within the White Sands Missile Range (WSMR), a sprawling U.S. Army-managed complex in New Mexico’s Jornada del Muerto desert basin. DTRA is a relatively small and obscure organization that plays a leading role in U.S. military efforts to develop new and improved ways to respond to Weapons of Mass Destruction (WMD) threats.

WSMR and DTRA have come up in discussions about strikes on Iran in the past. The U.S. military’s heaviest conventional air-dropped weapon, the 30,000-pound-class GBU-57/B Massive Ordnance Penetrator (MOP) bunker buster bomb, has been extensively tested at multiple sites there in the past. DTRA was also directly involved in its initial development. MOPs made their combat debut during U.S. strikes last year on underground Iranian nuclear facilities at Fordow and Natanz as part of Operation Midnight Hammer. The possibility has been raised that a different site within WSMR may have been used to test the plan of attack against Fordow, which involved two ventilation shafts being hit with six GBU-57/Bs each. The bombs were dropped in rapid succession, with each one burrowing deeper and deeper into the facility below. WSMR also happens to contain the site of the first atomic bomb test in 1945.

“The plans for the test [at ALT-SHIST] were connected to the Iran war,” CNN said in its story, published yesterday, citing unnamed sources “familiar with the matter.” Beyond that, the planned testing was tied to a “need to develop a way to target Iran’s deepest-buried underground facilities and, likely, simulate U.S. strikes against specific nuclear facilities.”

CNN said it was unable to independently verify whether or not the test in question had occurred.

A formal justification for the sole-source contract to Pate Construction that DTRA released in February did not mention Iran or elaborate on the need for the new testing at ALT-SHIST, but stressed there was an urgent requirement critical to U.S. national security.

“The services required are the immediate and mission-critical enabling services for a ‘real-world’ national security ordinance [sic; ordnance] test. This is not routine construction; it is the highly specialized remediation and operational preparation of a unique, subterranean test facility at White Sands Missile Range (WSMR),” according to the justification document, which DTRA officials had approved on February 24. “The work is a critical path dependency for a live-fire test designed to validate classified capabilities against rapidly emerging threats.”

“As the incumbent contractor for over a decade, Pate Construction Co., Inc. possesses unparalleled and non-transferable tacit knowledge of this specific subterranean test facility. This is a unique Government structure with complex geological and security considerations, and Pate Construction Co., Inc.’s direct, hands-on experience is a tangible asset that no other source possesses,” the document adds. “Pate Construction Co., Inc. is the only contractor that
currently maintains a fully mobilized presence at WSMR with the specific heavy equipment and security-cleared operators required.”

CNN‘s piece says apparent work at ALT-SHIST was visible in satellite imagery of the site between mid-February and mid-March, but the outlet said it was unable to confirm whether or not this was related to the contract with Pate Construction.

ALT-SHIST is an active test site, and any work observed there earlier this year could well have been linked to other projects. For instance, additional publicly available DTRA contracting documents offer details about planned work on a specific part of the ALT-SHIST site, called Tunnel 7, tracing back to last year, as part of a project nicknamed Millstone Willemite 6 (MW-6).

“This task requires the construction contractor to repair and address the damage to Tunnel 7 caused by prior incidents, in accordance with government-provided designs, specifications, and other contract documents,” according to one contracting document dated September 15, 2025. “The contractor will also be responsible for providing support during testing activities, as well as safing after each test and general support between tests. All tunnel construction must be completed by 15 June 2027.”

“The contractor shall repair a D-shape tunnel and overburden using the D-shape of 20 feet depth and width, inside the tunnel. The contractor shall remove and repair any damage to the ribs, crown, and invert to Tunnel 7,” that same document continues. “After the repair of Tunnel 7, the contractor shall provide general construction support to instrument the tunnel in preparation for testing and then safe the tunnel for re-entry post-testing.”

The schedule for the MW-6-related work indicates that it is separate from what Pate Construction was hired to do at the site back in February.

ALT-SHIST, which was first established in 1995, is also not the only site DTRA makes use of within WSMR. As its name indicates, it is an alternate to the original SHIST site, use of which began in 1993.

“There was a small addition made to the SHIST site, but that area has been heavily used since 2007,” according to an environmental impact study the U.S. Army Corps of Engineers (USACE) completed in 2015. “The granite bedrock at these sites has been fractured and damaged by extensive testing. There are no existing granite areas adjacent to those sites where similar testing can be performed.”

USACE conducted that study in support of the establishment of a new test site at WSMR, simply called the Granite Test Site, to succeed the original SHIST. The Granite Test Site is now in use. There are many more sites within the range complex designed to simulate underground and otherwise hardened targets. This is also just one aspect of the wide array of testing that occurs on a daily basis at WSMR.

However, the presence of large areas of undisturbed granite is a key factor here, as that is particularly relevant for testing weapons designed to penetrate into extremely deeply buried facilities. CNN‘s piece yesterday noted that Iran’s Pickaxe Mountain site is built underneath a granite mountain.

“The mountain in White Sands, they specifically picked mountainous areas that were solid rock, and they used state-of-the-art tunneling technology to make the kind of cavities in the mountain that you would put this kind of [Iranian nuclear] facility in,” Gary Stradling, a retired scientist who previously worked for the Department of Energy’s Los Alamos National Laboratory (LANL), told TWZ in an interview last year. “I think that there is a lot of work that DOD has done in these kinds of facilities that is highly classified, and I couldn’t talk to you about it. This is very sophisticated work. It is not casual, and it’s not speculative. These are real experts who are doing the work. Careful, technical, quantitative work to be able to deliver this kind of war-fighting capability to the services.”

TWZ spoke to Stradling, who did work tied to earth-penetrating munitions at various points during his lengthy career, in the wake of Operation Midnight Hammer.

The U.S. military notably did not strike Pickaxe Mountain, which is situated immediately to the southwest of Iran’s nuclear facility at Natanz, during Operation Midnight Hammer. The site also went untouched by Israel during last year’s 12 Day War. American and Israeli forces did not target it during major combat operations earlier this year, either. All of this underscores the targeting challenge the site presents, even for strikes using MOPs, which TWZ explored in detail earlier this year and that has continued to make it a point of particular discussion.

CNN‘s report yesterday was primarily focused on a new assessment of ongoing construction at Pickaxe Mountain from the Center for Strategic and International Studies (CSIS) think tank in Washington, D.C.

Satellite “images reveal more road activity at Pickaxe Mountain in 2026 than at any point in the site’s history,” according to a report CSIS published yesterday. “There is a clear surge in construction activity in 2026 that corresponds to the raising and hardening of the portal accesses, paving of the internal road network, reinforcement around access areas, and the flattening and removal of excavation spoil.”

“This assessment can neither refute nor substantiate the Israeli intelligence claim that Iran moved centrifuges into Pickaxe Mountain,” CSIS’s report also noted. “The continuous construction, the absence of an increased internal security posture, and the lack of observed nonconstruction vehicles and equipment suggest the underground facility is not yet capable of enrichment work, if that is the intended purpose. Further analysis of daily activity would be needed to establish the site’s pattern of life beyond its current construction footprint.”

This is in line with TWZ‘s own previous reporting on Pickaxe Mountain back in July, when there were already signs of growing activity following the establishment of a shaky ceasefire between the United States and Iran the preceding month. As we wrote at that time:

“As with the strikes on Fordow, multiple bombs could be dropped on the same impact point to try to penetrate further down into Pickaxe Mountain. Whether there might be similar ventilation shafts or other weak points that could be exploited at Pickaxe Mountain is unknown. …”

A graphic with details about the employment of MOPs on strikes at Fordow during Operation Midnight Hammer. DOD

“A strike ‘right in the front door’ on the tunnel entrances at Pickaxe Mountain would be another option to at least hamper access to the facility inside for a time. This could be combined with strikes aimed at sections of the tunnel networks that run deeper inside the facility, but that are still close enough to the surface to be reachable by available conventional munitions. For instance, MOPs may not be able to hit the main cavern areas, but they could possibly hit certain tunnels that might lead to them.”

“Even a combined strike on entrances and shallow tunnels at Pickaxe Mountain could still present certain challenges. Firm intelligence on exactly where the tunnels snake under the mountain could be limited, making it difficult to select the best impact points. This is exactly why the U.S. military has been investing heavily in advanced, void-sensing fuzes for MOP and other bunker buster bombs for decades now. These fuzes detect when a munition has penetrated into a sufficiently large space, such as a room or tunnel in an underground facility, to help maximize damage. Fuzes that can effectively ‘count’ floors also help to ensure the munition has burrowed sufficiently deep before detonating.”

…

“…the U.S. military could conduct follow-on strikes on the entry points at Pickaxe Mountain to disrupt any attempt to regain access, as well.”

“Destroying Pickaxe Mountain will be a scientific and targeting challenge,” CSIS also noted in its report yesterday. “It is an underground fortress buttressed by granite. It is one of the only facilities in Iran’s nuclear program that the United States has not yet struck. Structurally degrading Pickaxe Mountain requires more than just kinetic force – it takes actionable high-confidence intelligence and sophisticated mathematical modeling.”

With all this in mind, it is not at all hard to imagine how new testing at ALT-SHIST, as well as other sites, would be essential for exploring additional options for striking Pickaxe Mountain and/or other deeply-buried targets in Iran using MOPs and/or other munitions.

It’s also worth noting here that GBU-57/Bs are understood to be in relatively short supply, though it is unknown how many of them are currently in inventory. Furthermore, the U.S. Air Force’s B-2 Spirit bombers are currently the only aircraft certified to employ the huge MOPs operationally. There was a report in 2024 that prime contractor Boeing was working to expand its capacity to produce these bombs. A MOP successor, the GBU-76/B Next Generation Penetrator (NGP), is in development now, but prototyping work is expected to run through the end of Fiscal Year 2028.

President Donald Trump certainly has raised the prospect of a strike on Pickaxe Mountain publicly on several occasions since July. He has also repeatedly said that the site is being persistently surveilled, particularly from space.

“There’s another place called Pickaxe Mountain, another nice place. We may have to give them a shot there, too, because someone said there was a little movement at the site,” Trump said yesterday during a speech at a convention the Republican Party is hosting in Dallas, Texas, ahead of this year’s midterm elections. “We don’t need much. We see everything, you know, because of Space Force.”

“We may hit Pickaxe [Mountain] very soon,” the President also said while speaking to reporters at the White House last Friday.

Whether growing activity at Pickaxe Mountain finally prompts a U.S. strike at the site, either alone or as part of a larger operation, remains to be seen. If and when such a mission is launched, past and future testing at sites like ALT-SHIST in New Mexico will all but certainly have played an important part.

Operational F-15EXs Drop Live Bombs For The First Time

10 September 2026 at 17:49

The Oregon Air National Guard’s 142nd Wing has taken another significant step toward turning the F-15EX Eagle II into a true multirole fighter, conducting the first live-bomb drops from operational F-15EXs during training at Nellis Air Force Base, Nevada. The milestone came during a roughly three-week deployment to Nellis in late August and early September in support of the U.S. Air Force’s Weapons Instructor Course (WIC).

Jay Aebi, non-commissioned officer in charge of weapons loading, 142nd Aircraft Maintenance Squadron, loads a bomb onto an F-15EX Eagle II aircraft at Nellis Air Force Base (AFB), Nevada on August 27, 2026. The 142nd Wing’s fleet of F-15EXs operated at Nellis AFB for three weeks in late August and early September in support of the U.S. Air Force’s Weapons Instructor Course (WIC). During this time, the unit hit a historical milestone, dropping live bombs from operational F-15EXs for the first time. (U.S. Air National Guard photo by Master Sgt. Steph Sawyer)

Photographs released by the Air National Guard yesterday show F-15EXs from the 142nd Wing carrying live bombs on the flight line and departing Nellis with the weapons loaded. Official imagery shows the jets armed with a single 500-pound Mk 82 freefall bomb on the fuselage centerline, while spotters also captured F-15EXs carrying a 2,000-pound Mk 84 freefall bomb in the same position.

The 142nd’s F-15EXs are only now acquiring a capability that was deliberately absent from the wing’s previous F-15C fleet. The Portland, Oregon-based unit was an air-superiority organization when it operated the F-15C, while the F-15EX is ultimately derived from the F-15E Strike Eagle and has considerably more inherent multirole potential.

As we reported in July, the wing had already begun laying the groundwork for this transition. In May, 142nd personnel traveled to Mountain Home Air Force Base, Idaho, where they loaded and dropped inert BDU-50 and BDU-56 training bombs from their F-15EXs. Those weapons replicate the size and weight of 500-pound-class Mk 82-series and 2,000-pound-class Mk 84-series bombs. Over 10 missions, the crews dropped 24 BDU-50s and 12 BDU-56s.

While the F-15EX had already been tested in an air-to-ground role by the Air Force’s test community, the Mountain Home deployment was the first time an operational Eagle II unit had loaded and dropped bombs. The next step, the wing said at the time, would be live weapons employment at Nellis.

The Air Force has emphasized that the F-15EX’s primary mission remains defensive and offensive counter-air, particularly in the homeland-defense role. At the same time, the service’s plans call for the aircraft to provide combatant commanders with strike packages capable of operating in contested environments.

The F-15EX is inherently well suited to such a mission. Derived from the Strike Eagle lineage, it combines that aircraft’s large payload capacity and long range with substantially modernized avionics and electronic warfare systems. The aircraft’s design leaves considerable room for additional weapons and mission equipment, making an expansion into air-to-ground operations relatively straightforward compared with trying to add that capability to the F-15C.

The 142nd has been building the institutional knowledge required to make that transition. Three of its pilots underwent a nine-month course covering the science, tactics, and procedures associated with air-to-ground weapons employment before returning to help establish the wing’s training program. Weapons personnel also traveled to Nellis earlier this year to work with F-15Es assigned to the 59th Test and Evaluation Squadron and become certified in bomb loading procedures.

As well as teaching pilots how to release a weapon, the wing had to develop an entirely new air-to-ground training pipeline for pilots, maintainers, and weapons personnel at a unit that had not previously operated an aircraft with an operational bombing mission.

Nellis is home to the Air Force’s Weapons School and is central to the Weapons Instructor Course, making it one of the most important locations in the service for developing and evaluating advanced tactics. The 142nd’s participation therefore places its emerging F-15EX air-to-ground capability in an environment specifically focused on integrating advanced weapons, tactics, and mission planning.

The wing’s new live bomb-dropping capability also comes as the Air Force continues to explore how broadly the Eagle II can be employed.

Test and evaluation units have already demonstrated that the aircraft can accommodate sophisticated air-to-ground weapons. Earlier this year, an F-15EX from the 85th Test and Evaluation Squadron participated in a munitions-load training event at Kadena Air Base in Japan, where Air Force personnel practiced loading live GBU-53/B Small Diameter Bomb IIs onto the aircraft.

The F-15EX is also capable of carrying the conformal fuel tanks used by the F-15E, which can provide additional fuel as well as additional weapons stations. The operational F-15EXs delivered to the 142nd have so far been seen without CFTs, however, and the status of the plan to equip the Oregon aircraft with them remains unclear.

CFTs could become increasingly important if the Air Force moves toward more demanding air-to-ground missions for the Eagle II, particularly those requiring substantial weapons loads and long-range operations.

Another unresolved question is how the Air Force will ultimately crew F-15EXs when they are performing more complex multirole missions.

The Eagle II retains the F-15E family’s two-seat cockpit, although the Air Force’s initial operational concept has generally involved flying the aircraft with a single pilot. That leaves an unused cockpit that could potentially become an important asset as the mission set expands.

Former 142nd Wing commander Col. Michael Kosderka previously told TWZ that the addition of a weapons systems officer or other specialist in the rear cockpit could open the door to more air-to-ground capabilities.

“We can start talking about putting all kinds of air-to-ground capabilities into the airplane, potentially putting WSOs or other experts in the backseat as well to have us do any number of multi-role capabilities that it’s just physically not possible to in the C model,” Kosderka told TWZ in an interview back in 2024. “So the X has tremendous growth capability. It’s really exciting.”

Two crew would be particularly relevant to complex strike missions, where managing sensors, weapons, communications, electronic warfare, and other mission systems can place substantial demands on a single pilot. As we have discussed in the past, a back-seater would also be highly beneficial for the emerging drone controller role.

The Weapons School has also been associated with developing two-seat F-15EX operations, indicating that the second cockpit’s utility is already being considered at the tactical-development level.

For now, it would be premature to characterize the F-15EX as an operational replacement for the F-15E Strike Eagle in the air-to-ground role. The 142nd’s newly demonstrated bombing capability remains part of an ongoing training and development process.

Meanwhile, the Air Force is preparing to field substantially larger numbers of F-15EXs. Beyond the 142nd, additional Guard units are planned to receive the type, in California and Louisiana, as well as Michigan.

The Air Force has announced plans to base F-15EXs at Seymour Johnson Air Force Base, North Carolina, where they will eventually replace older F-15Es, which, in turn, are slated to move to Whiteman Air Force Base, Missouri, as part of a broader realignment of the Eagle fleet.

Another two active-duty F-15EX squadrons are slated to replace the former F-15C force at Kadena. The first F-15EX for permanent assignment at Kadena recently departed Boeing’s St. Louis, Missouri, facility for the 142nd Wing, where it will undergo final preparations before its eventual deployment to sprawling Okinawa.

The operational implications of the air-to-ground training therefore extend well beyond Portland.

The Eagle II’s generous weapons payload, long range, modern sensors and electronic warfare systems, and ability to carry both air-to-air and air-to-ground weapons give the Air Force a platform that can potentially perform several missions without sacrificing the characteristics that make the F-15 attractive for homeland defense and counter-air operations. The same characteristics are also extremely relevant to any export operator, which would expect to operate the Eagle II in a multirole capacity.

As well as a weapons-training milestone, the first live-bomb drops by the 142nd Wing provide more evidence that the F-15EX’s mission is continuing to evolve.

Russia’s New Stealthy Lower-Cost Air-Launched Standoff Weapons On Display In Egypt

8 September 2026 at 17:52

Russia is displaying some of its newest air-launched precision weapons in public for the first time at the El Alamein International Airshow in Egypt this week. The S-71K Kovyor and related S-71M Monokhrom, and the S8000 Banderol, reflect Russia’s effort to field larger numbers of relatively inexpensive standoff weapons alongside its more sophisticated and costly missile types. As such, their development and early employment are closely tied to the war in Ukraine, but they also reflect wider global interest in these kinds of weapons.

The weapons, seen in the tweet embedded below, comprise, clockwise from top left: S-71K Kovyor, an unknown smaller guided munition, S8000 Banderol, and S-71M Monokhrom:

For Russia, the requirement has become increasingly important as the war in Ukraine has evolved into a prolonged contest in which industrial capacity is as critical as technology. Russia has expended huge numbers of cruise and ballistic missiles against Ukrainian targets while also developing an enormous strike-drone campaign. At the same time, Ukrainian air defenses have become progressively more capable, forcing Moscow to use combinations of missiles, drones, decoys, and different flight profiles to penetrate or saturate the defensive network. One lesson is the fact that a weapon does not necessarily have to be as capable as a high-end cruise missile if it can be manufactured in much greater numbers and still present a credible threat to the target.

The S-71M, which TWZ previously reported on in detail after Ukrainian intelligence obtained an example, is a compact, turbojet-powered weapon with a distinctly angular airframe intended to reduce its radar signature. Imagery from Egypt gives a better look at its front end, including a faceted nose flowing into a broad central fuselage. The nose has at least one optically flat transparency for an infrared or TV seeker. Its wings are sharply swept and fold against the belly of the weapon for carriage, while the rear of the weapon terminates in an inverted-V tail arrangement. The overall shape is notably different from Russia’s more conventional cruise missiles of the past.

Ukrainian analysis found that the S-71M incorporates an OFAB-250-270 high-explosive fragmentation bomb as its warhead and relies primarily on inertial guidance, rather than carrying a sophisticated terminal seeker, although the seeker window raises questions about that.

Ukrainian intelligence also described its construction as being relatively straightforward, with fiberglass composite material making up much of the outer structure and no evidence identified of specialized radar-absorbing coatings.

As we noted previously, the weapon appears intended as a less expensive, but still survivable standoff weapon option that can be produced in significant numbers.

The S-71M has been tested from the Su-57 Felon fighter, also present at El Alamein. In a press release, the United Aircraft Corporation (UAC), responsible for the Su-57, said that the S-71M and the S-71K displayed alongside it “were designed for fifth-generation fighters,” although there is no reason why they couldn’t be launched from a wide variety of platforms.

Regardless of launch platform, the nature of the war in Ukraine makes the S-71M particularly useful. Russia has increasingly relied on extemporized glide bombs for attacks against targets relatively close to the front, but those weapons require the launching aircraft to operate within a certain distance of Ukrainian defenses. At least in their earlier iterations, such weapons were also crude and prone to failure. Longer-range cruise missiles offer considerably greater standoff but are more complex and expensive. The S-71M sits somewhere between those categories, providing an air-launched, powered weapon with a relatively large warhead and some degree of low observability without the cost and complexity of a full-size, truly stealthy cruise missile.

The S-71K appears to represent a more capable version of the basic concept. Public information remains limited, but the weapon has been associated with electro-optical guidance and greater onboard processing, potentially giving it a capability to deal with targets in a more flexible manner than the largely pre-programmed S-71M. Exactly how that capability is employed, and how autonomous the weapon actually is, remain less clear from the imagery and information released to date.

As displayed at El Alamein, the S-71K retains the overall faceted, low-observable appearance of the S-71M but has a visibly different airframe and wing arrangement. Its body is notably broad and compact relative to its length, with folding wings that are relatively thick, and a more refined inverted-V tail giving it more the appearance of a small uncrewed aircraft than a conventional air-to-surface missile.

Meanwhile, the Banderol represents a somewhat different path to the same general problem. Ukraine’s intelligence service previously obtained and analyzed an example of the small jet-powered cruise missile, which TWZ reported on last year. The weapon is considerably smaller than Russia’s principal cruise missiles and has been associated with launch from drones and helicopters. Its reported range of around 500 kilometers (311 miles) and relatively small warhead make it something of a complementary system intended to provide another, more economical way of putting a precision weapon onto a target from the air.

In terms of its appearance, the Banderol is more conventionally missile-like, with an ogival central fuselage, a pointed nose, and sharply swept folding wings. Its proportions underline just how small it is compared with Russia’s better-known air-launched cruise missiles.

The Banderol is particularly relevant in the context of the economics of the Ukraine conflict. Russian forces have increasingly used combinations of relatively inexpensive one-way attack drones and more expensive cruise and ballistic missiles. The drones can be produced in large numbers and used to complicate air-defense operations, while the more capable missiles provide greater speed, range, payload, or penetration capability. A small turbojet-powered weapon such as Banderol offers another point on that spectrum.

At least one image has recently emerged showing a Banderol carried by a Russian Mi-28NM Havoc attack helicopter. This would be in line with unconfirmed reports from Ukraine last month that Russia was using the Mi-28 as an additional launch platform for the weapon, including firing them from over the Sea of Azov to attack targets around Odesa.

Its reported use also illustrates how the distinction between a cruise missile and a large one-way attack drone is becoming increasingly blurred. The Banderol incorporates a conventional missile-like airframe and jet propulsion but has been associated with drone operations and makes extensive use of commercially available components. TWZ’s earlier examination of the weapon also highlighted the extent to which modern Russian weapons programs can combine relatively simple airframes with foreign-sourced electronics and propulsion technology.

Seen together at El Alamein, the three weapons provide an unusually useful snapshot of where Russian air-launched strike development is heading. They are presented alongside a fourth, so-far unidentified munition. This unnamed weapon is notably short and fat, with a cruciform tail, and an optical window in the nose. Its overall size and shape suggest it may have been developed specifically to arm drones.

The appearance of the weapons at an arms fair underscores the fact that Russia is not the only country confronting the problem of producing and fielding sufficient precision weapons at an acceptable cost. The growing interest in lower-cost cruise missiles, loitering munitions, attritable aircraft, and other forms of expendable precision strike is now evident well beyond Russia.

Russia is also clearly trying to make these weapons harder to intercept, an increasingly important consideration as Ukrainian air defenses have demonstrated an ability to shoot down even glide bombs in some circumstances. The S-71K in particular incorporates unusually pronounced low-observable shaping, suggesting that survivability was also a central requirement from the outset.

There is, however, a significant complication to Russia’s attempt to turn its wartime experience into an export opportunity. Buying any kind of weapons from Moscow has become considerably more difficult because of sanctions, restrictions on access to foreign technology and financing, and the wider political risks associated with maintaining a Russian defense relationship. Those factors matter just as much to a prospective customer as the performance of the weapon itself.

Author’s note: earlier reporting on the S-71 family appears to have transposed the S-71K and S-71M versions. Most authoritative accounts now indicate that the more refined, more stealthy version is the S-71K Kovyor (meaning carpet), while the simpler weapon is the S-71M Monokhrom.

Update, September 9:

Rostec, the Russian state-owned defense conglomerate, has provided more details of the weapon identified at El Alamein as the Banderol. Rostec calls this weapon the ‘Dan-T’ loitering munition, which is an export designation for Banderol.

According to Rostec:

The ‘Dan-T’ munition operates on a ‘fire-and-forget’ principle and is adapted for launch from Russian and foreign aircraft and helicopters. The munition is equipped with a compact jet engine and can strike targets at a range of hundreds of kilometers. The ‘Dan-T’ features a special flight mode designed to evade enemy air defence systems.

Rostec adds that the Dan-T has been combat-tested in the war in Ukraine, where it claims there have been “hundreds of successful launches” against enemy targets in the Special Military Operation zone. “We expect this munition to attract widespread interest from foreign customers,” said Rostec.

Missile Shortage Has Now Hit Ukrainian F-16 Force

By: TWZ

Ukrainian F-16 pilots are facing such a severe shortage of air-to-air missiles that some daytime sorties have seen them rely solely on the fighters’ internal guns to engage Russian aerial threats, according to a journalist who recently spoke with a senior Ukrainian Air Force commander. Meanwhile, the lack of air-to-air missiles means that the available weapons stocks are now being rationed.

The disclosure provides a remarkable glimpse into the day-to-day reality of Ukraine’s F-16 operations. While the aircraft may be available, the pilots may be ready, and Russian drones and cruise missiles may be approaching, there may simply not be enough missiles on hand to arm the jets.

According to Newsmax journalist Shelby Wilder, the Ukrainian Air Force can find itself monitoring missile shipments as they cross the country’s border, with personnel counting not just the hours but the minutes until those weapons reach the aircraft. The concern is whether the missiles will arrive in time for the next major Russian aerial attack.

The Ukrainian commander, who identified himself by the callsign “Phantom” and as commander of the country’s 107th Wing, confirmed the underlying problem when asked directly whether Ukraine was severely short of missiles for its F-16s.

“Yes, that’s true. Any aircraft without weapons is … useless,” Phantom said.

That blunt assessment is particularly striking given what Ukraine is asking its F-16s to do, and the relentless nature of Russian bombardments against Ukrainian cities and infrastructure.

The fighters have become an important part of Ukraine’s layered air defense network, hunting Russian drones and cruise missiles while also providing a potential counter to Russian combat aircraft, and conducting air-to-ground sorties. Ukraine has operated the F-16 since the summer of 2024.

“We are focusing on defending our skies against Russian unmanned drones to protect our infrastructure inside the country,” Phantom said. “Our target priority is cruise missiles.”

Destroying as many incoming threats as possible before they reach Ukrainian cities and infrastructure requires missiles, with the F-16 primarily armed with the AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) and the shorter-range AIM-9 Sidewinder.

According to the new disclosure, those missiles have become a commodity whose availability can determine how a sortie is flown.

The F-16 carries an M61A1 Vulcan 20mm rotary cannon, but using the gun against an aerial target is fundamentally different from engaging it with a missile, and comes with its own risks, as we have explored before. This tactic is especially hazardous when going after small targets and especially slow ones, and it becomes even more dangerous at night.

Ukraine has already demonstrated that its F-16s can use their guns in combat. In May 2025, the Ukrainian Air Force said an F-16 pilot had destroyed three aerial targets and was engaging a fourth with the aircraft cannon before an emergency forced him to eject.

One air-to-air weapon not mentioned by Phantom is the laser-guided 70mm Advanced Precision Kill Weapon System II (APKWS II) rocket, now apparently also part of the arsenal. These rockets would offer the Ukrainian Air Force an extremely valuable, lower-cost option for engaging drones and subsonic cruise missiles. 

Regardless, Phantom specifically called for additional air-to-air missiles, as well as interceptors for ground-based Patriot batteries.

“We require more means of protection, such as Patriot missiles and air-to-air missiles, AIM-9s or AIM-120s to our fleet,” he said.

Phantom’s message is that simply delivering more aircraft is not enough. Ukraine needs a sustainable weapons pipeline to keep those aircraft combat-effective.

This is increasingly becoming a wider problem across Ukraine’s air defense network. Patriot interceptors have been heavily consumed, with relatively few replacement missiles now trickling in, leaving Ukraine with limited ability to defend against ballistic missiles in particular. The strain is now spilling into the lower tiers, including the air-to-air missiles carried by F-16s. Ukraine’s continued consumption of interceptors is a major driver, but it is competing with the enormous demand generated by ongoing wars in the Middle East and a broader surge in demand for advanced air defense weapons around the world. With production struggling to keep pace, scarce interceptors are effectively being rationed across an increasingly crowded global battlefield.

“At least we need to try to increase the production, or at least to allow Ukraine to localize the production in Ukraine or other European countries,” he said.

That proposal reflects the fundamental vulnerability of a relatively small fleet operating in a high-intensity air war. Every missile fired at a Russian cruise missile or drone is one less available for the next engagement. A finite inventory therefore has to cover both routine air-defense missions and the possibility of much larger Russian attacks. At the same time, both the AIM-9 and especially the AIM-120 are used for Ukrainian ground-based air defenses too. The AMRAAM, in particular, is the effector for the NASAMS, which protects Kyiv, and other key objectives against cruise missiles and drones.

The problem becomes even more acute because Ukraine cannot know precisely when the next major Russian strike will arrive.

That is why, according to Wilder’s account, the arrival of missile shipments is being followed with extraordinary urgency.

At the same time, Phantom welcomed the major technological leap that the F-16 represents over the Soviet-designed MiG-29s and Su-27s that formed the backbone of Ukraine’s fighter force.

“The F-16s in comparison with the legacy aircraft like MiG-29 or Su-27? This is kind of like a new technology,” Phantom said.

But sophisticated aircraft are only as useful as the weapons available to them.

Ukrainian F-16s have reportedly destroyed huge numbers of Russian drones and cruise missiles, and in July a Ukrainian F-16 was publicly identified by the U.S. Joint Chiefs chairman as having shot down a Russian fighter.

Phantom also asked Ukraine’s Western partners to think beyond individual weapons transfers and toward production capacity.

He also urged the United States and European countries to do more to prevent Russia from acquiring components used in its own missile production through third party countries.

“We need to make as much as we can to stop providing the parts, most technological parts to Russians, bypassing the direct sales, of course, through the third party,” he said.

Phantom argued that Russia continues to obtain sophisticated components through intermediaries and even ostensibly civilian products.

“It would not be a surprise that Russians [are] using the washing machine that they’re buying from the third party to use those smart details for building missiles,” he said.

His recommendation is tighter sanctions and enforcement designed to cut off Russia’s access to those components.

“Important is to sanction to stop Russia from being able to have access to those parts,” he said.

That, combined with missile shortages, could become an even bigger problem when Russia conducts another major aerial campaign against Ukraine, particularly as Moscow traditionally intensifies attacks against the country’s energy infrastructure during the winter months.
