Pratt & Whitney, IHI Celebrate 2 Million Flight Hours with Japan Air Self Defense Forces

EAST HARTFORD, Conn., Friday, February 21, 2014

Pratt & Whitney has reached more than 33 years of flying F100 engines with the Japan Self Defense Forces (JSDF), which equates to approximately 2 million flight hours. In late 1975, the JSDF selected the F-15, powered by Pratt & Whitney F100-100 engines, to serve as their new air self-defense fighter. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

"Pratt & Whitney has provided reliable and affordable engines for the JSDF for many years," said Bennett Croswell, president, Pratt & Whitney Military Engines. "We are very happy to have powered the JASDF F-15 fleet to this 2 million flight-hour milestone, and we look forward to powering many more milestones for the fleet. We are in the middle of our journey together with the F100, and we're looking forward to beginning another journey with the next generation F135 engine and the F-35 Lightning II."

Production took place at IHI Corporation in Japan, and in 1981 the first batch of aircraft and engines entered into service with the Japan Air Self Defense (JASDF), a branch of the JSDF. This marked the first of many aircraft and engines that would be delivered over the next several decades. In fact, the first engine, which powered the F-15J, was delivered by a Kawasaki C-1 powered by the Pratt & Whitney JT8D engine. By the time production was completed in 1999, more than 200 F-15J aircraft and more than 400 F100 engines were built in Japan.

In Japan, IHI is the primary contractor and manufacturer for the aircraft engines used by the Japan Ministry of Defense and participates in international collaborative projects that develop and supply various market segments, from very large to small engines for civilian aircraft. In November 2013, IHI signed a contract with Pratt & Whitney to qualify components for the Japanese fleet of F135 engines that power the fifth generation F-35 Lightning II, and both companies are working on a series of industrial participation stand-up contracts for addition F135 capability and in-country F135 final assembly.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, auxiliary and ground power units and small turbojet propulsion products. United Technologies Corporation, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and building industries.
