Britain, Italy and Japan are combining their resources to create a new generation of fighter jets.
“We are announcing the Global Combat Air Program (GCAP) – an ambitious endeavor to develop a next-generation fighter aircraft by 2035,” the three nations said in a joint statement.
Other countries, including the United States, may also join the collaborative jet-building effort.
"We have begun important collaboration through a series of discussions on autonomous systems capabilities, which could complement Japan's next fighter program among other platforms," the United States and Japan said in a joint statement.
The announcement of the development of the fighter jet comes as Russia, China and North Korea have become increasingly aggressive.
