Yemen’s Houthi movement, formally known as Ansar Allah, has released imagery that it says shows the downing of a Royal Saudi Air Force F-15 fighter over Marib governorate. The material includes photos of the wreckage of an F-15 on the ground. At this stage, the fate of the two crew members is unclear. The incident comes amid a major escalation in fighting between Saudi Arabia and the Iran-aligned Houthi movement.

A video of what Ansar Allah says is the successful shootdown of the F-15 shows the typical ground-based forward-looking infrared (FLIR) systems we have seen in use by air defenses in Yemen previously, and, more recently, in Iran.

After a period of relative calm following the 2022 truce, fighting has intensified in recent weeks, with Houthi forces making significant advances against Saudi-backed Yemeni government positions, including around the strategically important coastal areas of Marib and Taiz. The group has also stepped up missile and drone attacks against southern Saudi Arabia, targeting military and energy infrastructure while strangling the kingdom’s ability to move oil through the Red Sea. The Houthis have further declared the Bab el-Mandeb closed to Saudi oil traffic, directly challenging one of Riyadh’s key energy-export routes.

Prior to the release of imagery, earlier today the Houthi military spokesman Brig. Gen. Yahya Saree claimed that Houthi forces had shot down a Saudi F-15 while it was conducting operations in support of Saudi-backed forces in Marib. Saree said the aircraft was engaged by a locally manufactured surface-to-air missile, although he did not identify the weapon. Reuters likewise reported that the Houthis had claimed the shootdown but that the claim had not been independently verified.

Saree also claimed that Houthi air defenses subsequently engaged formations of Saudi F-15s and Eurofighter Typhoons that entered the area while attempting to locate the downed aircraft. According to the Houthi account, those aircraft were forced to withdraw. That portion of the claim has likewise not been independently verified.

Saudi Arabia has not, at the time of writing, publicly acknowledged the loss of an F-15. Reuters reported that the Saudi-led campaign had intensified considerably in recent days, with Saudi aircraft striking targets across Yemen while the Houthis have launched missiles and drones toward Saudi territory.

The aircraft appears to be an F-15SA, the most advanced variant of the Eagle operated by the Royal Saudi Air Force. Specifically, it appears to be tail number 5539, assigned to the 55th Squadron based at King Khalid Air Base.

The Royal Saudi Air Force received 84 of the new-build F-15SA. Meanwhile, the 68-strong fleet of earlier F-15S aircraft has been upgraded locally to a similar standard, also known as F-15SR (for Saudi Retrofit). Aircraft 5539 is understood to be among the latter.

The reported shootdown highlights the continuing threat posed by Houthi air defenses, which have proven considerably more capable and difficult to suppress than their improvised appearance might suggest.

As TWZ has previously detailed, the Houthi air-defense network includes mobile surface-to-air missile systems, repurposed infrared-guided R-73 and R-27 air-to-air missiles, and Iranian-derived systems such as the Saqr/358.

Of particular concern is the group’s use of passive infrared sensors for detection, tracking, and missile cueing. Unlike conventional fire-control radars, these sensors do not provide an aircraft’s electronic-warfare systems with an early warning that it has been detected or targeted. TWZ has noted that this combination of mobility and passive sensing can create a difficult problem even for highly sophisticated combat aircraft, with the Houthis having previously demonstrated the ability to threaten U.S. crewed and uncrewed aircraft.

That capability does not mean that Houthi air defenses constitute a conventional, integrated air defense network comparable to those operated by major state militaries. However, they can still be effective through a combination of concealment, mobility, passive detection, unconventional employment of missiles, and the difficult operating environment over Yemen.

Previous Saudi aircraft losses attributed to Houthi air defenses during the Yemen war from 2015 to 2022 include several helicopters, fixed-wing aircraft, and drones. Total Saudi losses to all causes in the conflict amount to around a dozen helicopters, five jets, and as many as 30 drones. A Saudi F-15 crashed in the Red Sea at the start of the war in 2015 and Eagles were also reportedly engaged and damaged by Houthi surface-to-air missiles in 2018, although they returned safely.

Video footage that emerged in 2021 shows Saudi troops on the ground watching an F-15 swoop in a relatively low level to knock down a Houthi Qasef-series suicide drone:

In the past, Houthi forces have come close to engaging U.S. F-35s and have repeatedly demonstrated an ability to bring down MQ-9 Reaper drones. If the Saudi F-15 loss is ultimately confirmed, determining precisely how the aircraft was detected, tracked, engaged, and hit could therefore provide valuable insight into how this unusual air defense architecture is being employed against Saudi and other combat aircraft.

As we discussed at the time, the clear risk posed by Houthi air defenses is likely the main factor behind Saudi employment of a Chinese-made short-range ballistic missile (SRBM) in the current fighting with Yemen.

The timing of the reported shootdown is also notable. It comes amid a sharp escalation in the conflict, with Saudi Arabia conducting air operations against Houthi positions in Yemen and Ansar Allah launching missiles and drones toward targets inside Saudi Arabia. Reuters reported that the Houthis had attacked the Saudi Red Sea port of Yanbu and a southern airbase at Khamis Mushait, while Riyadh has reported intercepting Houthi drones.

The F-15 incident also follows a separate confrontation over an alleged Houthi drone attack near Mecca. Saudi authorities said their air defenses intercepted and destroyed a Houthi drone south of Mecca before it entered the restricted airspace over the city. The Houthis denied targeting the holy city.

Meanwhile, there are reports that U.S. officials met representatives of the Houthis in Oman over the weekend, with the Houthis apparently telling the U.S. officials that they had no intention of attacking American vessels and that they remained committed to the 2025 ceasefire with ​the United States unless they stepped in on behalf of Saudi Arabia. The Kingdom reportedly requested exactly this in recent weeks but was denied.

For the moment, the most that can be established from the available imagery is that a Saudi F-15 was destroyed, with Ansar Allah claiming responsibility.

This is a developing story and will be updated as additional imagery, official statements, or other independently verifiable information becomes available.

Israel’s Rafael and Lockheed Martin are working to accelerate integration of the 1,000-pound-class SPICE standoff weapon with the Israeli Air Force’s F-35I Adir. The development could potentially open the door for the precision-guided munition to be offered to other Joint Strike Fighter operators.

Rafael Advanced Defense Systems announced the effort September 15 during the Air & Space Forces Air, Space and Cyber Symposium that TWZ is attending. The work is being conducted as a joint project with Lockheed Martin at the U.S. contractor’s facilities in the United States and is expected to take several months.

AFA 2026: For the first time, Rafael's SPICE 1000 is being integrated on the F-35

Rafael says the effort could eventually make the weapon available to other F-35 operators. “At a later stage, F-35 operators worldwide will be able to field SPICE 1000,” the company said.

The effort was previously referenced in U.S. government documentation before Rafael’s announcement. Published in August, the Pentagon F-35 Modernized Selected Acquisition Report identified the weapon as the “Israel-unique Smart, Precise Impact, Cost-Effective 1000B,” or SPICE 1000B, and said its integration was progressing “with a strategy to accelerate the implementation via a SPICE Lite process.”

The report does not explain what the “SPICE Lite” process entails.

SPICE — which stands for Smart, Precise Impact, and Cost-Effective — is a family of electro-optically guided standoff weapons developed by Rafael. The family includes SPICE 2000, SPICE 1000, and SPICE 250, with the numbers corresponding broadly to the weight class of the underlying warheads.

Based around a 1,000-pound-class bomb, SPICE 1000 uses pop-out wings to achieve a manufacturer-stated range of approximately 125 kilometers, or 78 miles. Rafael gives the weapon a claimed circular error probable of around three meters.

The glide bomb combines inertial and satellite-aided navigation with an electro-optical seeker. During the terminal phase, its seeker can compare the observed target area with stored imagery using scene-matching algorithms, allowing the weapon to continue its attack without relying exclusively on GPS. That feature allows it to engage targets autonomously, offering the launch aircraft a true ‘fire and forget’ capability, and provides resilience in GPS-denied or GPS-degraded environments.

SPICE can also be programmed to approach a target from a particular azimuth and impact angle. This provides flexibility in selecting the terminal attack geometry and can support steep attack profiles against targets where penetration from above is desirable.

SPICE 1000 is not a new Israeli capability. It has been operational with the Israel Air Force since 2017 and is already integrated with Israeli F-16I Sufa, F-16C/D Barak, F-15I Ra’am, and F-15 Baz fighters.

“SPICE 1000 has been sold to several countries and is in operational service with a number of air forces worldwide,” Rafael said. “It has served as a primary munition of the Israeli Air Force for several years, including extensive use in recent long-range operations flown from F-15 and F-16 aircraft.”

The Israeli Air Force has released footage showing SPICE weapons being used during recent operations, including imagery from the weapon’s own perspective during its terminal attack.

Israel’s F-35I is already unusual within the international Joint Strike Fighter fleet. The IDF has developed and demonstrated an external Joint Direct Attack Munition (JDAM) carriage capability, and said in March 2025 that the Israeli Adir was the only F-35 to have conducted operational strikes with an external weapons configuration. You can read more about that here.

However, according to The Jerusalem Post, the SPICE weapon is expected to be carried internally by F-35Is equipped with Technology Refresh 3, or TR-3, hardware, which would maintain its low-observable configuration. Neither Rafael nor Lockheed Martin has publicly detailed the specific carriage configuration, aircraft modifications or software associated with the current integration effort.

The long-delayed TR-3 is a major upgrade to the F-35’s computing architecture and provides the processing infrastructure required for subsequent Block 4 capabilities. Israel received its first three F-35Is equipped with TR-3 hardware in January of this year.

Lockheed Martin describes Block 4 as the F-35 program’s “most significant evolution of F-35 capabilities to date,” encompassing more than 70 major upgrades, including increased weapons capacity, advanced electronic warfare capabilities, and improved target recognition.

It remains unclear if the SPICE 1000 integration itself requires the full Block 4 configuration.

The potential significance of the Israeli integration extends beyond the Israel Air Force. If SPICE 1000 ultimately becomes available to other F-35 operators, the completed Israeli integration could provide those countries with another pathway toward fielding a precision standoff weapon rather than requiring them to begin an integration effort entirely from scratch.

Integrating national weapons onto the F-35 can be a lengthy process. It involves not only the weapon itself, but aircraft software, interfaces, weapons-bay compatibility, flight testing, mission-system integration and certification within the U.S.-led F-35 program.

The United Kingdom’s experience with MBDA’s SPEAR 3 provides a good example of the challenges.

In 2022, the U.K. Ministry of Defence said that scheduled delivery dates for SPEAR 3 had been delayed because of “prioritisation in the overall F-35 development programme,” which is managed by the U.S.-led F-35 Joint Program Office.

The program has continued to progress, including F-35B integration work and flight testing. But in June 2026, the U.K. government said that completion of mission-systems integration and jettison trials remained part of a wider weapons-integration program and that SPEAR 3 integration and subsequent release to service would occur in the early 2030s.

The United Kingdom has consequently approved the acquisition of the GBU-53/B Small Diameter Bomb II as an interim standoff weapon for the F-35B until SPEAR 3 enters service.

Nevertheless, another F-35 operator would not be able to adopt the Israeli SPICE integration without additional work. National configurations, software baselines, certification requirements, weapons procurement, and export approvals would still have to be addressed.

Already, however, aided by its uniquely configured test jet, Israel has demonstrated an unusual ability to integrate nationally developed capabilities onto its F-35I. This has been aided by privileged access to the Joint Strike Fighter’s closely guarded software codes.

A U.K. parliamentary report noted delays in integrating British weapons onto the F-35B while contrasting that with Israel’s ability to integrate domestic electronic warfare systems, sensors, and communications technology onto its Adir.

Meanwhile, Rafael and Lockheed Martin already have experience working together on the SPICE family.

The companies signed a teaming agreement in 2019 covering the joint development, marketing and manufacture of SPICE guidance kits for the U.S. market. In 2021, they expanded the agreement to include SPICE 250, including development for potential sales to the United States and Poland. With some unque capabilities, SPICE could be of particular interest to the U.S. military, especially as it seeks to leverage multiple sources of precision munitions.

The SPICE family also extends beyond the 1,000-pound-class weapon now being integrated with the F-35.

At the other end of the family is SPICE 250, a much smaller weapon designed around a 250-pound-class payload. It incorporates a man-in-the-loop capability that allows an operator to redirect the weapon during its flight and abort the attack if necessary.

Its smaller dimensions also allow substantially greater weapon carriage. Rafael has marketed configurations in which a fighter can carry as many as 16 SPICE 250 weapons.

SPICE 1000, by comparison, is a substantially heavier weapon intended to provide longer-range precision attack capability with a larger warhead.

The SPICE effort is taking place alongside several other Israeli initiatives aimed at extending the F-35I’s range and weapons capabilities.

The Pentagon’s F-35 documentation has referenced ongoing work on extended-range fuel tanks and electronic warfare pods for the Israeli Air Force, although it did not provide fielding dates.

In May 2026, Israel’s defense ministry awarded an extended-range capability development contract for the F-35I to Elbit Systems subsidiary Cyclone. The capability is intended to increase the aircraft’s radius of action and reduce its reliance on aerial refueling during long-range missions.

Israel has also announced a major expansion of its F-35I fleet, with plans to increase the number of aircraft from 50 to 100. The country is simultaneously expanding its forthcoming F-15IA fleet from 25 to 50 aircraft.

For the F-35I, SPICE 1000 adds a long-range strike option that pairs the aircraft’s low observability with substantial standoff range and a relatively heavy warhead. This offers a survivability advantage in increasingly contested environments, allowing attacks from farther outside capable air defense systems and under heavy electronic warfare conditions. This factor will only become more important as integrated air defense systems become more capable and the F-35 more detectable.

Exactly how the weapon will be integrated remains undisclosed. Rafael and Lockheed Martin have not announced the final carriage configuration, aircraft software requirements, flight-test schedule, or expected date for operational clearance.

At the same time, Rafael is explicitly positioning the effort as a potential pathway for SPICE 1000 to become available to the wider F-35 community. This would conceivably give other operators another option at a time when integrating a new standoff weapon onto the fighter can take years.

The post Israel Is Bringing SPICE 1000 Standoff Weapon To The F-35 appeared first on TWZ.

As both the Navy and the USAF were racing to field a new generation of advanced tactical jets, the seagoing service’s program hit a wall. A major reason behind this from the Pentagon was concern that the U.S. industrial base could not handle simultaneous final development and production of two extremely complex new fighter aircraft. This was a controversial justification that many had a hard time swallowing. The Navy’s program, dubbed F/A-XX, is supposedly back on and a down-select on who will build it is coming soon, but that concern appears to linger among at least one of the Department of War’s top acquisition officials.

Though he remains confident that the U.S. Air Force F-47 sixth-generation fighter will fly in the next two years, Air Force Gen. Dale R. White, Director, Critical Major Weapon Systems — the service’s leading weapons procurement advisor — remains concerned about the overall capacity of industry to provide the military with the aircraft it needs, including two new fighters. His comments were in response to questions about the Navy’s challenges in building its own sixth-gen fighter alongside F-47.

The concerns are “not unique” to the F-47 or the Navy’s program but the problem exists to various degrees across the industrial base too, White told reporters Tuesday during a media roundtable at the Air & Space Forces’ Air, Space and Cyber Conference that TWZ is attending.

White has a dual-hatted role, serving as the Pentagon’s top weapons procurement officer and as the senior acquisition advisor to the Secretary of the Air Force for all acquisition matters.

“We’re seeing it in multiple platforms,” said White, who did not elaborate. “And so what we’re having to do is, at some point, we’re having to make some trade space in between some of these.”

“I see Boeing making smart investments,” White said of the prime contractor of the F-47, selected for the U.S. Air Force’s Next Generation Air Dominance (NGAD) ‘fighter’ initiative. “They have a lot of CAPEX [capital expenditure] that they’re pouring in, but we have to get through the process of the design piece, getting that completed and closed out. Then we all hit some major milestones with things like flight tests and software and those things.”

“Really, it’s just being able to manage the overall resourcing as it relates to number one, people resources,” the general added. “Number two, when you start getting into the production conversation, do we have enough capacity to be able to produce at that rate? And so, by and large, I have concerns. I have concerns about the capacity of our industrial base, but they are not unique to F-47 or to any program.”

As for the F-47, White said the program “continues to progress exceptionally well.”

“As you know, many, many years in tech maturation and risk reduction gave us a tremendous head start on this program,” White explained. “Extremely proud of what the team has done, what they continue to do each and every day. We are still absolutely on [the] path to be able to hit the mark of flying within this administration. So we see no issues in front of us right now.”

While the first example of the F-47 has been in production for about a year now, the Navy has yet to even select a prime contractor for its next generation fighter. The current competitors for the F/A-XX are Boeing and Northrop Grumman. A decision was supposed to have been made by last month.

“The F/A-XX program remains on track, and we have no further information to provide at this time,” a Navy official told us last week.

Despite intervention from Congress, the next-generation carrier-based fighter has remained in question since the Pentagon moved to effectively shelve the program last year.

In response to a question from TWZ earlier this year, the Chief of Naval Operations acknowledged the uncertainty over the F/A-XX program.

“One of the challenges we’re seeing is, not only [are] our peer competitors improving their capability for anti-air, either air-to-air or surface-to-air, but the lower cost of entry of very capable weapons is also making more players on the field in which that level of stealth and technology is required,” Adm. Daryl Caudle told us back in April at the Sea-Air-Space 2026 exposition. “So this is not about the need for a peer adversary. This is just having an aircraft that can operate with a level of uncertainty and with the acceptable level of risk.”

With Boeing as a finalist, it is also possible that F/A-XX could be a variant of the F-47. As we noted in a past story, the Boeing render for its F/A-XX concept is remarkably similar to artwork for its F-47.

Likely a navalized F-47 variant as expected. https://t.co/4lZkpUjqfz

Last year, Steve Parker, Boeing Defense and Space CEO, said he didn’t see a problem with his company building both jets stating that this had been part of the strategy all along.

If this is the case, the company’s claim that it would not have a problem building both the Navy and Air Force next-generation fighters would make more sense. There are a number of advantages when it comes to establishing a high-degree of commonality between F/A-XX and F-47, although there would also be challenges, especially when it comes to getting the most out of a design that was not meant to operate from a carrier deck and scaling production up for both services. There is already significant sharing of elements of both the Navy’s and Air Force’s sixth-generation fighter programs. So commonality in some subsystems and interoperability are already baked in.

We should hopefully finally get a clearer picture in the coming weeks about the status of the F/A-XX and possibly the answer to who will actually build it, which will give us a better idea of what the industrial base impact actually will be.
