After F-35 Woes, Japan Mulls Own Steath Fighter Program

By Joseph Hammond

Major Akinori Hosomi, vanished on a cool evening in April 2019 while flying one of the world’s most modern and deadliest aircraft — the F-35A Joint Strike Fighter. 

When the 41-year old pilot took off from Misawa Air Base in northern Japan on the night of 19 April 2019 there was little sign of trouble. An experienced pilot with 60 hours on the F-35A, the multirole jet he was flying was state of the art, and the mission profile was to be another routine night-training exercise. Yet, his plane fell into the Pacific Ocean without so much as a distress call on the part of the pilot.

Japanese authorities later revealed that the 41-year-old pilot likely suffered from vertigo or ‘spatial disorientation’ after taking off from Misawa Air Base. His multirole fighter is believed to have suffered from navigational and cooling errors before the crash. Throughout the course of the investigation and recovery, potential salvage efforts by a hostile power remained a significant concern for both Tokyo and Washington.

Hosmi’s night-time crash lead to a four-month halt to all F-35 flights by Japan’s Air Self Defence Force (JASDF). The crash represents however the most fatal part of Japan’s troubled relationship with one of the world’s most expensive warplanes. The helmet alone, filled with advanced sensors, costs $400,000.

This summer the US Department of State approved a $23 billion plan for Japan to acquire 105 Lockheed Martin F-35 stealth fighters of both the conventional take-off (the F-35A), and the short take-off and vertical landing variant (the F-35B).

As a result of this deal, Japan is now home to one of only two F-35 production final assembly and check-out (FACO) facilities located outside of Fort Worth, Texas — where Lockheed Martin maintains the primary F-35 production facility. 

However, like its European counterpart, production in Japan was forced to shut down earlier this year owing to the onset of the COVID-19 pandemic. The impact of the virus has also delayed the training of the JASDF’s F-35 test pilots due to concerns about virus transmission among this most elite cadre of pilots. The backlog will last until at least 2023 and extend the date the jets will enter active services with the Self Defence Force.

By then, however, Japan may be well into the development of its next system — the F-X development program — a next-generation warplane developed by local industry. Japan is currently seeking to develop a domestically produced stealth fighter, alternatively known as the F-X or F-3 project. The project has surprised some analysts given that Japan cancelled plans for X-2 stealth fighter prototypes in 2018. 

Mitsubishi Heavy Industries is now in pole position on a $40 billion contract for that program after developing the X-2 prototype in 2016. Northrup Grumman, Lockheed Martin, and BAE systems had all floated offers but, so far, Japan has decided to go it alone on its new fighter that will complement its inventory of F-35s. Since the end of the Second World War, Japan has only developed two combat aircraft, the F1 (developed in 1975) and the F-2 (derived from the F-16 which entered service in 2006). The latter is likely to be phased out by the end of the current decade. 

Ironically, the development of multiple airframes might be to Japan’s advantage. The F-35’s advanced sensor capabilities may mean that it would work better in formations where it uses its sensors to see over the horizon and ‘quarterback’ information and roles of the other aircraft in the formation.

The F-35 program is an important one” says Jon Grevatt, a Bangkok based Asia-Pacific defence industry analyst, “but, even more, important for Japan is the development of the F-X development program which seeks for Japan to develop a next generational multirole fighter domestically. While the timeline on that project is developing, the F-35 is likely to be critical to the security aspirations of Japan over the next two decades“. 

The development of the F-X or F-3 will open a new chapter in Japan’s defence history. After World War II, Japan adopted a pacifist constitution that limits the role of its military. As a result, Japan only began weapons exports in 2014 under former Prime Minister Abe Shinzo. 

Given the general relaxing of Japan’s pacifist structures over recent decades, including refitting the Izumo class helicopter destroyers as aircraft carriers equipped with the F-35B, the F-X fighter, when completed, could also be a target for high-end export to third party countries. Ironically, it was the issue of arms exports that placed the Japanese defence industry in this position. Japan’s Ministry of Defence was interested in purchasing the F-22 Raptor but, the Obey Amendment (House Amendment 295 to H.R.2266) of the US Congress prevents the export of this aircraft, even to close treaty allies.

With that in mind, Japan is likely to continue seeking partners — the United States or the United Kingdom could potentially play a role in that project. In particular, a joint effort with Britain would be politically useful for both countries. The United Kingdom is currently working on its advanced fighter jet, ‘Tempest’ a twin-engine, delta-winged, low-observable fighter opening another possible avenue for partnership. 

Meanwhile, Japan’s Acquisition, Technology & Logistics Agency (ATLA) made clear it was open to partnering with either country in statements this year but, a final decision will not be reached until December 2020 at the earliest. In the meantime, Japan has a lot of F-35s to build.
