A long-range kamikaze drone that U.S. firm Kratos is working on together with Taiwan’s National Chung-Shan Institute of Science and Technology (NCSIST) is set to make its maiden flight early next year. The jet-powered Chien Feng IV (Mighty Hornet IV) will feature artificial intelligence (AI) enabled systems and is being developed with a particular eye toward use as an anti-ship weapon. It could also be employed against targets on land and act as a decoy.
Steve Fendley, president of Kratos’ Unmanned Systems Division, offered new details about the Chien Feng IV while speaking with TWZ‘s Howard Altman on the sidelines of the Air & Space Forces Association’s 2025 Air, Space, and Cyber Conference yesterday. A model of the design, which is derived from Kratos’ MQM-178 Firejet target drone, was shown to the public for the first time last week at the biennial Taipei Aerospace & Defense Technology Exhibition. NCSIST is a government-run organization in Taiwan charged with conducting advanced military research and development and test and evaluation work.
Chien Feng IV will fly “soon, early next year,” Fendley said. “The basic aircraft exists. So what we’re doing is we’re integrating mission capability.”
“Our Fire Jet performance characteristics are public, and it’s [Chien Feng IV] a little bit better, pretty much in every category, a little bit more speed, a little bit more altitude, a little bit more endurance,” Fendley added.
“The modified MQM-178’s high-speed capabilities, including a speed of Mach 0.8, high G maneuvering, and a service ceiling of greater than 35,000 feet, make it an ideal base platform for this transformation,” a press release Kratos put out last week had noted.
At the time of writing, the company’s website also says the MQM-178 can fly at altitudes anywhere between 20 and 35,000 feet, can pull turns down to -2 and up to +9 Gs, and carry around 70 and a half pounds of payload internally, as well as 35 pounds more under each wing and an additional 20 pounds in pods on each wingtip. Range and endurance figures for Firejet are not provided, but are offered for an existing derivative called Airwolf, which is configured for tactical mission sets, including acting as a ‘loyal wingman’ for crewed aircraft. Airwolf, also known as Tactical Firejet, has a stated maximum range of 400 nautical miles and a maximum endurance of 1.3 hours. Both Firejet and Airwolf are designed to be launched via pneumatic catapult, and the latter design at least can be recovered at the end of a mission via parachute.
The Chien Feng IV is “our aircraft and NCSIST, so the Taiwanese government, [their] mission systems and warhead,” Fendley said, and deferred to the Taiwanese side for more details about the latter components of the drone’s design.
A brief video on the Chien Feng IV that NCSIST released around the Taipei Aerospace & Defense Technology Exhibition, seen below, highlights an electro-optical/infrared camera system (EO/IR) in the nose, as well as an AI-driven computer and datalink, as being among the design’s features. In terms of terminal guidance, an EO/IR system would make sense as it is immune to electronic warfare and is passive in nature, meaning it doesn’t pump out signals that can alert the target to the incoming threat.
The Chien Feng IV model shown at the exhibition in Taipei was fitted with small underwing pods, which might be able to hold defensive countermeasures or other equipment, or even just more fuel. It also had an opaque nose cone, which could point to additional sensor options, such as a radar seeker.
The NCSIST video also mentions at least a degree of swarming capability, though it is unclear if Chien Feng IVs will be able to operate in a fully networked collaborative manner.
In terms of missions, Chien Feng IVs are expected to be tasked with “ship-hunting, ship-attacking, ground force-hunting, [and] ground-force attacking,” according to Kratos’ Fendley.
As noted, NCSIST has put particular emphasis on the anti-ship mission, which makes sense for Taiwan. Authorities on the island face the real prospect of the Chinese government on the mainland attempting to impose a blockade or even launch a full-scale military intervention across the Taiwan Strait. The People’s Liberation Army Navy (PLAN) and its steadily growing fleets of more capable surface warships would play a critical role in either scenario.
At the same time, the Taiwan Strait is just under 100 nautical miles across at its widest, and Chien Feng IVs with ranges of around 400 nautical miles would also be able to hold Chinese targets at risk on the mainland. At the Taipei Aerospace & Defense Technology Exhibition, NCSIST representatives said the drones could just be employed as decoys, according to a report last week from Jane’s.
If the Chien Feng IV’s AI-enabled systems give it the ability to find and engage targets in a highly autonomous manner, the drone’s capabilities could be magnified greatly in a maritime or land attack scenario, especially against moving targets. This, in turn, could present major complications for an adversary like China. TWZ previously explored in great detail how the steady infusion of AI and machine learning technology, especially when it comes to dynamic targeting and swarming, is pushing development of uncrewed aerial systems toward a revolutionary moment, broadly.
As noted in TWZ‘s past reporting on the Chien Feng IV, massed attacks involving these drones would also compel the PLA to expend commensurate amounts of anti-air interceptors, putting additional strain on Chinese air defenses. More capable interceptors would also be required to engage the higher-flying jet-powered attackers.
Taiwan is also now pushing to significantly expand its inventory of various lower-tier kamikaze drones, including in cooperation with U.S. defense contractor Anduril. This is in line with a larger strategy that American officials have discussed for helping to defend the island from any future Chinese intervention, which has been called “Hellscape” in the past. What is envisaged is the Taiwanese military heavily saturating the air and waters around the island with relatively low-cost uncrewed platforms.
NCSIST also reportedly has an eye toward exporting Chien Feng IV. There is certainly growing global interest in long-range kamikaze drones, driven heavily by observations of their use on both sides of the ongoing war in Ukraine. Attacks by Iran and its regional proxies on Israel and ships in the Red Sea, as well as targets in and around the Middle East, have also underscored the value of this kind of capability. Back in 2019, TWZ called out a then-unprecedented drone and missile attack that Iranian-backed Houthi militants in Yemen launched against Saudi Arabia as a sign of things to come.
“I would say that our recent program with Taiwan, I’m going to call as a spin off of, sort of a combination of Apollo and Athena,” Kratos’ Fendley also told TWZ yesterday.
Fendley did not further elaborate. Details about the Apollo and Athena programs remain limited, but the company has previously told TWZ that they are aimed at the European market. The possibility is now raised that one or both of those designs could be long-range kamikaze drones, or at least be capable of being employed in that role.
Kratos is otherwise pursuing new opportunities globally. This includes a partnership with Airbus on a version of the stealthy XQ-58 Valkyrie drone for the German Luftwaffe. Kratos has now sold two XQ-58s to Airbus, which are expected to start flying in Germany next year following the integration of new mission systems, according to Fendley. The Valkyrie has already been flying for years in a largely experimental role with the U.S. Air Force and the U.S. Marine Corps. The Marines are now in the process of transitioning their XQ-58 efforts to an operational capability.
“Many, many domestic and international customers, who I’m going to say have been at the interest level, have transitioned to the we’re ready to do something level,” Fendley added, speaking more generally. “So, think some Asian countries, think some European countries, and the timeline is in, I would say the next 24 months, you’re going to see those happen pretty quickly.”
When it comes to the Chien Feng IV, specifically, more details may continue to emerge as Kratos and NCSIST get closer to the planned first flight next year.
