The Japanese Defense Ministry plans to acquire advanced air-to-ground missiles in order to arm F-35 stealth fighters. The missiles have the capability to attack targets at a range of 500km, considered outside the ranges of enemy missiles.
According to the Japan Times, the Defense Ministry is to acquire JSM missiles produced by Norway's Kongsberg company, which are among the most advanced and long-range ones for fighter planes, by the end of the year. The missiles are capable of downing sea and ground targets. The Kongsberg company confirmed the report on the supply of missiles to Japan.
The Defense Blog website reports that the Japanese Defense Ministry is also considering the acquisition of larger missiles made by Lockheed Martin with a range of 900km in order to arm the F-15J fighter, one of the most advanced fighters of the Japanese Air Force.
