Forget the F-35: Japan and the UK Could Build a Game Changer 6th-Generation Fighter

Tempest 6th-Generation Fighter from BAE Systems.

The United Kingdom and Japan are looking to unite their efforts on a 6th generation stealth fighter jet. First reported by Reuters, the scheme would link the British Tempest program with the Japanese F-X program by the end of 2022.

F-X & Tempest 

Mitsubishi Heavy Industries has been taking the lead on the Japanese F-X program, while Team Tempest, a group of different companies, is managing the Tempest program.

According to Reuters, the project will be an equal partnership between the two countries and is set to cost tens of billions of dollars—the F-35 Joint Strike Fighter program, which produced three aircraft, came with a price tag of more than $1.7 trillion.

The goal seems to design and build the same stealth fighter jet but with slight modifications for each country’s version.

In the past, Japan has only worked with the U.S. on joint military projects. If the Tempest and F-X programs unite, then it would be a first for Tokyo.

The F-X program is supposed to have a test aircraft ready by 2028 with full production scheduled for the 2030s, while the Tempest project aims to have an aircraft ready by 2027 with full production scheduled for the next decade too. So, in terms of timelines, the two projects are fairly similar. A scheme that would bring the two projects together would also make sense in budgetary terms.

In some recent statements with respect to the revelation that the first Tempest will be flying within five years, British Minister of Defence Ben Wallace gave a hint on the Japanese connection (Japan already plays a small part in Team Tempest).

“I am delighted that the UK, alongside Italy, Japan and Sweden are working on the same combat air journey together. Our work with Japan and Italy on cutting-edge technologies like this, shows the benefit of our alliances across the world,” Wallace said.

“The design and development of the demonstrator aircraft represents an important milestone, showcasing the success and talent of our engineers, programmers and software developers. This programme will go on to attract opportunities for many more great minds and talent from across the UK,” the British minister of defense added.

The Tempest 

According to the British Ministry of Defence, the Tempest will bring four main airframe features: balanced survivability, next-generation flight control system, adaptable physical architecture, and scalable autonomy.

These features aim to give the Tempest a wide variety of capabilities, including but not limited to, extensive battlefield situation awareness and data fusion, modular design to meet the operational needs of different operators, the option for manned and unmanned flight, and thermal management for more stealth.

In addition, Team Tempest, which includes BAE Systems, Leonardo, and Rolls Royce, among other companies, wants to have thrust vectoring capabilities on the Tempest similar to those of the F-22 Raptor. Thrust vectoring capabilities make an aircraft incredibly maneuverable and can produce some amazing acrobatics. Put simply, thrust vectoring allows the pilot to point the thrust of the aircraft’s engines in a different direction than that in which the aircraft is flying, thus allowing it to swiftly change direction.

    UK’s conduct here is treasonous to peace and those who perished fighting japanese imperialism.

    UK signed the 1905 anglo-jap alliance and together with the 1921 sempill mission set japan on the path to murderous war amd rampage.

    Japan’s aircraft carrier prowess during ww2 (especially at pearl harbor) would have been impossible without direct help from the british.

    Japanese naval aircraft like the nakajima A1n type 3, Aichi D3a type 99 and even the mitsubishi A6M type 0 could trace their lineage directly to british aircraft.

    Allied POWs were forced to work as slave labor in japan during ww2 and some were entombed alive at war’s end. The most notorious mines were sado mine and yoshikuma mine where over 100 POWs, mostly british and australian ones were sealed in the slave pits.

    UK action here is simply sacrilegious to their memory.

    Manned combat aircraft will soon be obsolete. Their purpose is to truck smart weapons to the battlefield, but drones can do that more efficiently, and with much less risk. The cost benefit ratio has long ago been past, and 10+ drones can be fielded for the price of one manned aircraft similarly armed with smart weapons.
