Japan's government on Tuesday selected the Lockheed Martin F-35 stealth fighter to bolster its aging air force, announcing it will buy a total of 42 aircraft under a multiyear deal.
Japan has budgeted the cost of four fighters next fiscal year, which starts in April, said Noriyuki Shikata, deputy Cabinet secretary for public relations.
Lockheed gave the average price per plane as $65 million. Details including exact timing of the deliveries, final price tag and quantities per year have yet to be finalized.
Japan wrestled for years over whether to buy the F-35, Boeing F-18 or the Eurofighter Typhoon, made by a consortium of European companies. The U.S. planes were seen as the favorites because of close U.S.-Japan military ties.
The F-35, also called the Joint Strike Fighter, is the Pentagon's biggest weapons procurement program _ costing $238 billion _ and has support from allies including Britain, Australia, Canada, Israel and several European nations. It is to be used by the U.S. Air Force, Marines and Navy.
Japan _ with 362 fighter jets, mostly F-15s, F-4s and F-2s _ is already one of the top air powers in the region. But planners have long been concerned by the increasing age and expense of maintaining the fleet, along with Japan's ability to match the improving air capabilities of its neighbors.
The new fighters would replace the F-4s.
To further sweeten the deal, Lockheed promised Japan a share of the assembly and production of the aircraft, which is important to local producers.
Japanese officials said they took into account cost, performance and the inclusion of Japanese companies in the manufacturing process.
"Lockheed Martin is honored by the selection," said Dave Scott, the company's director of F-35 international business development based in Fort Worth, Texas. "We're excited about working with Japanese industry to manufacture and deliver the F-35 for the Japan Air Self-Defense Force."
Washington is Tokyo's main ally. Roughly 50,000 U.S. troops are stationed in Japan under a security pact. Japan's air force must work closely with its American counterpart, and using the same or similar equipment makes that easier.
Japan's main concerns are China and Russia _ with which it has long-standing territorial disputes _ along with the threat of North Korean ballistic missiles.
China, whose military has been growing more capable and assertive, recently rolled out its next-generation stealth fighter, the much-touted Chengdu J-20. Though it may be years away from actual operations, it is seen as a rival to the best U.S. fighters and far superior to what Japan now has.
