Japan to boost its future stealth fighter force with 20 more F-35A jets, defence sources say
A purchase would add to an earlier order for 42 of the fighters, most of which are being constructed at a plant in Japan operated by Mitsubishi Heavy Industries

Japan plans to buy at least 20 additional F-35A stealth fighters over the next six years, some or all of which it may purchase directly from Lockheed Martin Corp in the United States rather than assemble locally, three sources said.
“In view of budgets and production schedules a new acquisition of around 25 planes is appropriate,” said one of the sources with knowledge of the plan. The sources asked not to be identified because they are not authorised to speak to the media.
The sources said buying complete aircraft from the United States, at about US$100 million each, will save Japan about $30 million per airframe.
The purchase will add to an earlier order for 42 of the fighters, most of which are being constructed at a “final assembly and check out” plant in Japan operated by Mitsubishi Heavy Industries, the country’s leading defence contractor.
That plant is one of only two such factories outside the United States. The other, in Italy, is operated by Leonardo Spa.
As China fields ever more advanced aircraft, including stealth planes, and as North Korea pushes ahead with its nuclear weapon and ballistic missile programmes, adding F-35s will further increase Japan’s reliance on US military technology to give it an edge over potential foes in East Asia.
