The UK, Japan, and Italy have finally signed an international treaty to develop a stealth fighter with supersonic capability and “equipped with cutting-edge technology.”

The fighter aircraft, which may be called “Tempest,” is expected to have the capability to carry advanced weaponry and will eventually replace the current fleet of FGR4 “Typhoons” used by nations like the UK. The new supersonic stealth jet will have a powerful radar that is capable of providing 10,000 times more data than current systems, providing immense advantage in battle. The joint development phase is scheduled to begin in 2025.

According to Interesting Engineering, the project will reportedly be headquartered in the UK and is expected to support the creation of hundreds of jobs, with initial leadership positions in Italy and Japan. The new treaty will also help support ” future Indo-Pacific stability and wider global security.” The first CEO will come from Japan, and the HQ will deliver vital military capability, strengthen each country’s combat air-industrial capability, and achieve value for money.

“Our world-leading combat aircraft program aims to be crucial to global security, and we continue to make hugely positive progress toward delivery of the new jets to our respective air forces in 2035,” said the UK’s Defense Secretary, Grants Shapps.

The UK Ministry of Defense’s public announcement states that the combat air aircraft, due to take to the skies by 2035, aims to harness next-generation technologies and become one of the world’s most advanced, interoperable, adaptable, and connected fighter jets in service globally. The program is expected to create highly-skilled jobs in the UK and partner countries over the next decade and beyond.

The aircraft is being developed in collaboration with hundreds of companies nationwide that are involved in the supply chain, while the main companies in the UK, Japan, and Italy, aim to advance the design and development of the aircraft.
