The South Korean government has released images from its first successful test of a domestically developed hypersonic boost-glide vehicle. This includes shots of the vehicle impacting the water at the end of its flight. A weapon of this kind would give South Korea a significant new way to hold targets in North Korea at risk amid an ever-deepening arms race on the Peninsula.

South Korea’s Presidential Office, more commonly referred to as the Cheong Wa Dae or the Blue House, announced the test in a Korean-language press release yesterday. The Blue House initially released a video of President Lee Jae Myung and others observing the test from a conference room at the Anheung Proving Ground, which is located in South Chungcheong Province on the country’s western coast. South Korea’s Agency for Defense Development (ADD) manages testing at Anheung. A series of still images from the test itself was subsequently posted on the Blue House’s website.

Included in the still image gallery are shots showing the launch of the missile, a formal name for which has not yet been disclosed, from a wheeled transport-erector-launcher on a platform sitting just off the coast. The low resolution of the pictures makes it hard to tell whether the missile and/or the TEL are of an existing South Korean design or are based on one. We will come back to this later on.

As mentioned, there are also pictures of the hypersonic boost-glide vehicle hitting the water. At first glance, the vehicle looks to have a broadly conical design with stabilizing fins at the base. However, at least one of the fins looks to be truncated. Closer inspection of the available images shows further indicators that might point to it actually having a more wedge-shaped design with a distinct top and bottom, though it is still not definitely clear given the low resolution. Conical boost-glide vehicles are generally understood to be easier to design, relatively speaking, than wedge-shaped ones. Historically, hypersonic boost-glide vehicles of any kind have proven to be technically complex and challenging to turn into viable operational weapons, even by countries with extensive past experience with their development.

“This test launch was conducted to verify, for the first time, the vehicle’s core technologies in a hypersonic flight environment: the performance of ultra-high-temperature heat-resistant materials, guidance and control capabilities, and the ability to perform irregular flight maneuvers at low altitudes,” the Blue House said in its release yesterday, per a machine translation of the Korean text. “The HGV [hypersonic boost-glide vehicle] successfully separated after ascending to the target altitude and executed its planned flight path within the hypersonic environment without any issues.”

With all this in mind, the fact that the vehicle just remained intact through to impact is noteworthy. At the time of writing, South Korean authorities do not appear to have disclosed more specific details about the test, including how far the boost-glide vehicle traveled before hitting the water or what peak speed it reached. Important questions also remain about how the vehicle is guided during the mid-course and terminal phases of flight, challenges that do not appear to have been addressed by this particular test.

In general, unpowered hypersonic boost-glide vehicles need to be brought first to an optimal altitude and speed. This is typically achieved using a sufficiently sized rocket booster, with existing ballistic missile designs often serving as a starting point.

Once released from the booster, a boost-glide vehicle flies along a relatively shallow flight path within the Earth’s atmosphere. The vehicle is able to maneuver along the way, sometimes erratically, while traveling at hypersonic speeds, generally defined as anything about Mach 5.

All of this sets hypersonic weapons of this kind apart from traditional ballistic missiles, even ones with advanced maneuverability capabilities, which all follow a broadly arcing trajectory to their targets. The combination of speed, flight trajectory, and maneuverability offered by hypersonic boost-glide vehicles creates distinct challenges for opponents. They are hard to spot and track, let alone attempt to intercept, and there is less time for defenders to react overall. This ability to penetrate enemy air defenses and cover ground rapidly makes these weapons particularly attractive for strikes on very high-value and time-sensitive targets.

“The HGV [hypersonic boost-glide vehicle] is a ‘key strategic asset capable of changing the game on the battlefield,’ as its unpredictable flight trajectory and overwhelming speed allow it to launch surprise strikes against key strategic targets during contingencies,” the Blue House’s release explicitly noted, again according to a machine translation.

With all this in mind, South Korea does have an entire family of domestically-produced ground-launched ballistic missiles that could be suitable starting places for launching an unpowered hypersonic boost-glide vehicle. President Lee was notably shown a TEL for the country’s newest Hyunmoo-5 ballistic missile at Anheung yesterday, though no explicit connection has been drawn between that weapon and the hypersonic test. The Hyunmoo-5 is itself still a relatively new development, having only entered service around the end of last year.

When it comes to new South Korean arms developments, the Hyunmoo-5, which entered service around the end of last year, has been and continues to be a major point of discussion by itself. It is officially categorized as a short-range design, despite how big it is (35 tons gross weight), which is said to be due largely to the equally substantial size of its warhead (17,000 pounds). Past reports have raised the possibility that it could be capable of flying out to intermediate ranges if the warhead weight were reduced. Short-range ballistic missiles are defined as ones with ranges between 190 and 620 miles (300 and 1,000 kilometers), while intermediate-range ballistic missiles can hit targets out to between 1,864 and 3,418 miles (3,000 to 5,500 kilometers). Medium-range ballistic missiles (MRBM) fall in between these two categories.

With its massive unitary warhead, the Hyunmoo-5 already gives South Korea an important new way to hold deeply buried and otherwise hardened targets in North Korea at risk. This fits in directly with the country’s broader Korea Massive Punishment and Retaliation (KMPR) policy, as TWZ has previously written:

“While the Hyunmoo-5 has been widely reported as a future pillar of the KMPR, its specific ability to penetrate deeply buried bunkers, such as those used by the North Korean leadership, the same functions mean that it can also fulfill elements of the ‘kill chain.’ In this way, it could be used as part of a pre-emptive strike, to try and knock out North Korea’s launch capability by targeting its hardened command-and-control facilities and missile storage areas.”

By virtue of the very high speeds they reach in the terminal phase of flight, hypersonic boost-glide vehicles also offer bunker-busting benefits on top of the other aforementioned advantages they bring to the table.

In addition, the hypersonic boost-glide vehicle test reflects a broader arms race that has been expanding in scale and scope for years now. South Korea is also developing an air-breathing hypersonic cruise missile, seen in the composite image below, as well as new air- and sea-launched ballistic missiles, the latter of which will be loaded on new surface warships and submarines.

Though there are always questions about the actual maturity and viability of the designs, North Korea continues to churn out its own new missile developments. This includes two separate test launches of purported new hypersonic designs just in recent weeks. Tit-for-tat missile launches are not entirely uncommon on the peninsula, but there are limits to how quickly a test like the one South Korea conducted yesterday involving an emerging technology can reasonably be staged.

Friction between the North and South has been at a particular high point, in general, following an incident on September 21, in which three South Korean troops were injured along the Demilitarized Zone (DMZ). South Korea’s Joint Chiefs of Staff (JCS), as well as the United Nations Command (UNC) on the Peninsula, have said a North Korean landmine placed in violation of the Armistice Agreement was to blame. South Korean authorities have demanded an apology and raised the prospect of some form of action in response, though President Lee has more recently sought to downplay the situation. The government in North Korea has denied the accusations and threatened an “immediate and powerful counteraction” should South Korea seek to retaliate.

An operational hypersonic boost-glide vehicle capability would also expand South Korea’s capacity to challenge opponents regionally beyond North Korea. Though the regime in Pyongyang represents the most proximate national security threat to the country, China and Russia have also been growing points of concern for South Korean authorities in recent years.

“We must secure our national security through our own strength,” President Lee said after yesterday’s hypersonic test, per the Blue House’s release. “The government must not rest on today’s success but must further advance the technology so that the hypersonic glide vehicle can establish itself as a robust strategic asset safeguarding our future security.”

South Korea’s very public test of its new hypersonic boost-glide vehicle underscores the country’s still-expanding efforts to broaden its options for striking even the best-defended targets in North Korea, as well as projecting power elsewhere regionally. At the same time, it remains to be seen when the South Koreans may field a real operational capability in this regard.

The post First Look At Hypersonic Boost-Glide Vehicle Just Tested By South Korea appeared first on TWZ.

Just over two years after the U.S. Air Force retired the last of its KC-10A Extender aerial refueling tankers, four of those aircraft may be bound for a new career in North Africa for a mysterious end user.

The Air Force Life Cycle Management Center (AFLCMC) put out a contracting notice yesterday “solely for information and planning purposes” with the express intent “to identify potential industry sources that possess the capability, expertise, and facilities to execute the regeneration, one-time flight clearance, depot-level return to service, worldwide ferry delivery, in-country Contractor Logistics Support (CLS), and operational/maintenance training for up to four (4) KC-10 Extender aircraft.”

The KC-10s could be “transferred via Excess Defense Articles (EDA) to a partner nation in North Africa,” the notice adds, without naming the country in question.

The Air Force operated KC-10s between 1981 and 2024. TWZ has reached out to the U.S. Air Force, as well as the U.S. State Department, for more information. The State Department directed us to contact the Pentagon.

The EDA program allows for materiel deemed extraneous to U.S. military needs to be transferred to allies and partners either at a reduced cost or as a grant. The foreign nation in question has to pay for those assets to be delivered, as well as refurbishment, if applicable.

It is important to note here that the Extender, as designed, is capable of refueling receivers using either the boom or the probe-and-drogue method. Tankers equipped for the probe-and-drogue method are, by far, more common internationally. We will come back to this later on.

While we don’t know what the North African country might be in line now to receive the quartet of KC-10s, Egypt and Morocco would seem to be the most likely candidates based on their current and planned aircraft inventories. They are also both major U.S. allies.

The Egyptian Air Force currently does not operate any dedicated aerial refueling tankers. The country is in the process of acquiring two new C-130J-30 Hercules aircraft for use as airlifters, as well as tankers, using the probe-and-drogue method. It does already fly C-130s, but none explicitly configured for aerial refueling duties. Egypt also has a very diverse array of fighters that includes U.S.-made F-16 Vipers that can only be refueled in mid-air via boom.

Morocco’s Air Force also flies F-16s and is in the process of acquiring more. The first new-production Block 72 F-16D for the Moroccan Air Force just flew for the first time earlier this week. Morocco does have an organic aerial refueling capability now, but in the form of C-130s equipped to dispense fuel via probe-and-drogue.

As mentioned, the KC-10 was designed to connect with receivers via probe-and-drogue, as well as boom, and could be used to refuel other tactical jets in Egyptian or Moroccan service. As an aside, fighters belonging to both regularly receive foreign tanker support during exercises, as already seen earlier in this story. Just last month, Chinese YY-20 tankers (also sometimes referred to as Y-20Us) notably did just this in an exercise in Egypt.

Whichever country may be in line to receive the four KC-10s, there is a question about the current state of those aircraft. Earlier in this story, we talked about the Extender’s capabilities as designed.

McDonnell Douglas (since absorbed into Boeing) delivered a total of 60 KC-10s to the U.S. Air Force between 1979 and 1987. The Extender was derived from the three-engine DC-10 airliner, the last of which was produced in 1989. The Air Force lost one of its KC-10s in an accident in 1987.

Of the remaining 59 KC-10s, 10 were put up for auction in a non-flyable state last year. For reasons that remain unclear, a single engine had been removed from under one of the wings of each of those aircraft. These Extenders were also among the first to be retired, and their booms had been stripped to be used as spares for the examples that remained in service until 2024. Private aerial refueling contractor Omega Air looks to have subsequently won those auctions. Omega also operates two ex-Dutch KDC-10 tankers, which are broadly similar to the KC-10, as well as another DC-10 converted into a probe-and-drogue-only tanker. The company has several Boeing 707-based tankers, as well.

The condition of the remaining 49 Extenders is unclear. Congress included a provision in the annual defense policy bill, or National Defense Authorization Act (NDAA), for the 2026 Fiscal Year that required the Air Force to preserve remaining retired KC-10s, but only stipulated they be maintained “in the same storage condition” they were in as of September 30, 2025. The bill, which was signed into law in December 2025, also made clear that the Air Force could still “dispose” of the aircraft in accordance with existing property management statutes.

Regenerating military aircraft, especially larger ones, back to service can be costly, complex, and time-consuming, even when they are kept in storage in a highly maintained state. In this particular case, acquiring KC-10s via the EDA program, with a very low up-front purchase price, could still be attractive to the right buyer, especially compared to the cost of acquiring new-production tankers.

For a country like Egypt or Morocco that has never operated a boom-equipped tanker, second-hand Extenders could be a valuable entry point to future aerial refueling capabilities, as well. In general, organic aerial refueling capability is an important force multiplier for any air arm.

There is a possibility that KC-10s could be regenerated not as tankers, but as cargo aircraft, though this seems less likely to be the case. Cargo carrying was also an important duty for the Extenders while in U.S. Air Force service, and they still could operate in this role even when returned to service as tankers.

Though the aging KC-10s were getting increasingly more difficult to operate and maintain, the Air Force’s decision to retire them was still controversial. The Extender was a highly flexible tanker that could carry more fuel than the KC-46s that supplanted them. Clearly, there are others still interested in operating them.

It should be stressed that the AFLCMC contracting notice does not present the transfer of the four KC-10s as a done deal. At the same time, it has revealed that one of America’s partners in North Africa could breathe new life into four of these retired tankers.

Standing on the deck of the aircraft carrier USS Abraham Lincoln, Secretary Pete Hegseth looked up at the flattop’s superstructure and got a good indication of many of the targets the Lincoln Carrier Strike Group (CSG) destroyed during its six-month fight with Iran. In a photograph shared by the Pentagon’s image distribution site, Hegseth is seen examining a wall of so-called kill marks stenciled onto the superstructure.

By our count from the image and a video taken during Hegseth’s visit, both of which you can see below, there are 103 one-way attack (OWA) drone kill marks and 34 ship kill marks. These represent the number of each the CSG took out. It is unclear whether there are other kill marks we can’t see.

Though they resemble Shahed-136s, which are the most notorious of Iranian OWA drones, these silhouettes would represent all types shot down, and Iran has many. The same holds true for the ships. The photograph shows stencils of frigates or corvettes but these would be a generic symbol for surface craft kills.

On board to welcome the ship and its crew as it headed back to its home port of San Diego after a tumultuous and historic deployment, Hegseth extolled the strike group’s accomplishments. Reading from the Presidential Unit Citation awarded to the strike group for its work during Epic Fury, Hegseth noted that it shot down 77 one-way unmanned attack drones and sank 64 Iranian vessels between the start of Epic Fury on Feb. 28 until it departed the region on Aug. 22.

The Lincoln CSG also conducted 3,693 combat sorties, delivered 1.37 million pounds of ordnance, launched 450 Tomahawk Land Attack Cruise Missiles (TLAMs), destroyed 21 anti-ship cruise missiles and defended against four fast-attack craft and explosive-carrying wooden sailing vessels.

It is unclear at the moment why there are at least 26 more drone kill marks stenciled onto the Lincoln than the number of drones shot down listed in the unit citation and why there are 30 fewer ship kill marks than the tally noted in the citation. The Pentagon referred us to the Navy, and we are waiting for a response from the service.

There is a long tradition of kill marks being stenciled onto aircraft, vessels and other military equipment indicating the destruction of enemy equipment.

Kill marks on aircraft embarked aboard Lincoln indicate that the carrier strike group also destroyed several Iranian submarines and other weapons. These were not listed in the unit citation or in any kill marks stenciled onto the Lincoln that we could see.

An image provided to TWZ by aviation photographer Jeff Rojas, who goes by the handle @jro_photography on Instagram, shows a submarine kill mark on one of the F/A-18F Super Hornets of the U.S. Navy’s Strike Fighter Squadron 41 (VFA-41), the “Black Aces.” That is one of the aviation squadrons embarked on the Lincoln during Epic Fury.

Iranian naval vessels, including the country’s Russian-made Kilo class and other submarines, were top-priority targets during Epic Fury. The U.S. military has previously confirmed that air-launched AGM-114 Hellfire laser-guided missiles (likely fired from MQ-9 Reaper drones) and ground-launched Army Tactical Missile System (ATACMS) short-range ballistic missiles were employed against submarines, specifically.

In total, VFA-41 alone launched 421 missiles and bombs during its time supporting Operation Epic Fury. You can find the details in our story about the squadron here.

In addition, an image published by The Aviationist showed “an extraordinary array of target markings on a VMFA-314 F-35C, apparently representing an oil tanker, three submarines, a surface combatant, a Shahed-type drone, an artillery piece, and several ground-based launchers.”

It should also be noted that some of the drone kill marks seen on the Lincoln could have been the result of shootdowns by the carrier’s escorts. The Arleigh Burke class guided missile destroyers USS Frank E. Petersen Jr, USS Spruance and USS Michael Murphy all serve as critical air defense platforms for the carrier strike group. Those vessels were also the ones launching the TLAMs, as well as potential submarine involvement.

Late Thursday morning local time, Lincoln finally returned home. The carrier departed San Diego on Nov. 21, 2025, and an arrival closed out a total deployment of 321 days, by our count. That’s just shy of the 326-day record USS Gerald R. Ford set in May, representing the second-longest deployment in the modern carrier era.

In addition to racking up successes against Iran, the marathon deployment drew scrutiny over the grueling conditions sailors and Marines experienced aboard. In August, crew families described supply shortages and difficult living arrangements, as TWZ reported at the time. The accounts led to widespread media coverage, which Acting Secretary of the Navy Hung Cao called dishonest while also acknowledging that “a small number of mental health cases were treated with no loss of life, meal plans were adjusted when fresh resupply was unavailable, without a single meal being missed, calls home were limited when the operational threat was too high.” At least eight personnel across the strike group attempted suicide during the cruise, Cao wrote in a letter sent to Sen. Kirsten Gillibrand that was obtained by CNN.

The kill mark stencils weren’t the only symbols of Lincoln’s deployment. On Wednesday, Hegseth used symbology to push back against concerns raised about the long journey.

“There were a few folks in the media who tried to turn the USS Abraham Lincoln into some sort of a symbol,” Hegseth said. “A symbol of dysfunction, or a symbol of low morale, or a symbol of a failed mission. And what I look out right here or when I talk to your leadership, and I haven’t had a chance to talk to a number of you, I know it’s the exact opposite.”

UPDATE: 5:59 PM Eastern –

After the Lincoln pulled into its home port, new images emerged. The following picture shows additional kill marks, including 10 of submarines.

The United States is stepping up its campaign to sell Portugal the F-35. Speaking in Lisbon today, Secretary of State Marco Rubio said the United States would make Portugal a “very competitive” offer to replace its F-16 fleet. The development adds a high-level political push to an increasingly intense competition over the Portuguese Air Force’s next fighter.

Portuguese Foreign Minister Paulo Rangel said after meeting Rubio that Lisbon is seriously considering the American proposal, while emphasizing that other options remain under consideration.

“The Portuguese state will always decide in ‌accordance ⁠with the national interest,” Rangel said at a news conference after the meeting. “There is one point that is also clear: we are seriously considering the F-35 proposal, just as we are considering ⁠others.”

Portugal currently operates 25 modernized F-16AM/BMs, including 21 single-seat F-16AMs and four two-seat F-16BMs, from Monte Real Air Base, or BA5. The Portuguese Air Force, known as the Força Aérea Portuguesa (FAP), has not yet formally launched a replacement competition, but the aging fleet is increasingly becoming the focus of attention in Lisbon.

Portugal acquired a total of 45 F-16A/B Block 15 aircraft through the Peace Atlantis I and II programs.

The first 20 aircraft were delivered beginning in 1994. These were new-build F-16A/B Block 15OCU aircraft, comprising 17 single-seat F-16As and three two-seat F-16Bs, and were used to equip Esquadra 201 “Falcões.”

A second batch followed in 1999, when Portugal received 25 former U.S. Air Force Block 15OCU aircraft. Twenty-one were F-16As and four were F-16Bs, with several intended as attrition replacements or spares. These aircraft had accumulated roughly 3,000 flight hours and underwent an extensive modernization program to bring them to the F-16AM/BM configuration. This means the aircraft are broadly comparable to the U.S. Air Force’s F-16C/D Block 50/52 fleet. 

Esquadra 301 “Jaguares” finally became operational with its upgraded aircraft in 2005, while Esquadra 201 did not receive its upgraded F-16s until 2011.

Since then, the Portuguese Vipers have continued to receive incremental improvements. Their configuration has progressed through several mission-software standards, while the aircraft have been equipped with night-vision goggles, Joint Helmet-Mounted Cueing Systems (JHMCS), and advanced targeting and weapons capabilities.

Among the more important additions are Northrop Grumman Litening II targeting pods, and the ability to employ weapons including GBU-12 Paveway II laser-guided bombs, GBU-31 Joint Direct Attack Munitions (JDAM), and GBU-49 Enhanced Paveway II dual-mode weapons.

Twelve former Portuguese F-16s were transferred to Romania under a deal signed in 2013, with deliveries taking place in 2016 and 2017. Romania subsequently ordered five additional aircraft in 2019.

Structurally, the Portuguese F-16s could potentially remain in service into the mid-2040s. But maintaining their relevance against increasingly sophisticated air forces would require continued investment in avionics, sensors, communications, and self-protection systems.

The F-16AM/BM fleet continues to rely on the old AN/APG-66(V)2 pulse-Doppler radar. Replacing it with an active electronically scanned array (AESA) radar such as Northrop Grumman’s APG-83 would substantially improve detection and tracking performance, but would come at considerable cost.

Portugal faces a choice between continuing to invest in increasingly tired fourth-generation airframes or moving directly into the fifth generation.

Since the end of the Cold War, Portugal has become much more engaged in out-of-area operations and missions in support of NATO.

In the process, the Portuguese F-16 fleet has accumulated an impressive operational record.

The fighters have repeatedly deployed on NATO air-policing missions, including rotations to the Baltic States, Iceland, Romania, and Poland.

The F-35A would give Portugal a fifth-generation fighter built around low observability, sensor fusion, advanced electronic warfare, and networked operations.

The aircraft would also fit naturally into a NATO environment in which an increasing number of European air forces are adopting the F-35.

More than 900 F-35s are already in service or on order across Europe, according to previous comments by U.S. Ambassador to Portugal John Arrigo. Washington has repeatedly argued that joining that community would provide Portugal with a substantial interoperability advantage.

However, European competition includes the Eurofighter Typhoon, Dassault Rafale, and Saab Gripen E, with Airbus preparing an especially aggressive campaign for the Typhoon.

Airbus has said it intends to submit an unsolicited Eurofighter proposal to Portugal in late October or early November. That package is expected to encompass not just the aircraft, but financing, industrial participation and broader military cooperation.

Selecting the American stealth fighter deepens Lisbon’s military relationship with Washington at a time when European governments are wrestling with fundamental questions about their dependence on U.S. military capabilities.

Across the continent, uncertainty over Washington’s stance on NATO is encouraging European allies to examine ways of reducing their reliance on American military technology, even as those same countries continue to increase defense spending and purchase U.S. equipment.

If Washington can combine the F-35’s capability advantages with an attractive acquisition and sustainment package, Portugal could find itself facing a difficult choice between the strategic benefits of joining Europe’s growing F-35 fleet and the industrial and political advantages of selecting a European fighter.

The final decision on the replacement of the F-16 will also determine what combat jet spearheads the Portuguese Air Force for the next several decades.
