  • The UK, Italy, and Japan are working together to develop a sixth-generation fighter jet.
  • Saudi Arabia reportedly wants to join the effort, but Japan is said to be wary of letting Riyadh in.
  • The UK-Italy-Japan program is one of several launched in recent years to build next-gen jets.

Saudi Arabia wants to joint the UK, Japan, and Italy as a partner in the Global Combat Air Program, which aims to build the six-generation Tempest stealth fighter jet and other advanced technologies by 2035.

While funding from the Arab kingdom could ease the financial burden on the consortium, other considerations have made Tokyo reluctant to assent to Riyadh's admission.
