Japan is known to be upgrading its F-15 J fighter. It was initially
announced by Japan that it would modernize nearly 100 F-15 Js.
However, due to budget constraints, Japan decided it would only upgrade 68
aircraft to save money.
As quoted by Zonajakarta.com from Bulgarian Military, the upgrade of 68
Boeing-Mitsubishi F-15 J Eagle fighter aircraft is part of the Japan Super
Interceptor (JSI) program.
The modernization involves the integration of long-range missiles, radar,
increased payloads, and expanded capabilities for electronic warfare. It is
likely that the 68 fighters will also have a cost of living for 30 years.
Even so, Japan is known to have refused to equip F-15 J fighter jets with
LRASM long-range anti-ship missiles from Lockheed Martin due to price and
schedule problems.
On the other hand, the UK and Japan started cooperation in the development
of engines for the next generation of the Tempest and FX fighters. The two
countries have signed a memorandum of cooperation.
The UK is investing £30m next year in spending on planning, digital design
and innovation.
Meanwhile, a key part of the UK's Combat Air Strategy, backed by £2 billion
over the next four years.
This joint program will support the development of two next-generation
fighters the world expects in the next four years, the British Tempest
stealth fighter and the next-generation Japanese FX stealth fighter.
It is a future Japanese fighter jet that should replace the existing
Japanese F-2 aircraft.
