A new generation of military fire fighters is coming to the U.S. from Japan, where they will be deployed in a fleet of 30 planes, according to the Pentagon.
The U.K. is also deploying its newest generation of fighters.
The Japanese fighters will replace the aging U.R.F.P.s, and the British are also looking to replace older aircraft in the fleet.
But while the U and UK are the biggest, the UFPA’s are the smallest, at less than 5,000 aircraft.
Japan is also investing heavily in new F-35B fighter jets, with Japan’s Defense Ministry announcing it will spend more than $600 million on the planes.
A U.N. report this month found that Japan’s F-4 Phantom jets are the most dangerous of any of its fighters.
