Amid fresh UN-imposed sanctions on North Korea and further bellicose threats made by Pyongyang, Japanese and South Korean media have reported that their respective governments are considering additional F-35 Joint Strike Fighter orders. South Korea has established a process for procuring 20 additional F-35A fighters, adding to the 40 already ordered in 2014. Meanwhile, Tokyo may order the Short Takeoff and Vertical Landing variant of the next-generation fighter, the F-35B, which would allow the Japan Air Self-Defence Force to operate the aircraft from shorter runways as well as on board its Izumo-class helicopter destroyers, which could be retrofitted with ski-jumps and upgraded aviation fuel storage facilities to allow the aircraft operate off its deck.
