EAST HARTFORD, Conn., September 25, 2008 - Pratt & Whitney was awarded a production contract worth up to $491 million (including options) for F135 propulsion systems to power the F-35 Lightning II. This second F135 low rate initial production contract will support 12 F-35 production aircraft, including six short-takeoff/vertical-landing (STOVL) and six conventional take-off/landing (CTOL). Propulsion system deliveries are scheduled to begin in third quarter 2009. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

“This is our second production contract for CTOL engines and the introduction of the first production deliveries for the STOVL configuration,” said Bill Gostic, vice president, Pratt & Whitney F135 engine programs. “This milestone indicates the continued maturity of the F135 engine powering the F-35 today, and validates the confidence our customer has in the CTOL and STOVL propulsion systems.”

In addition to F135 propulsion systems, the contract covers program management, initial logistics support, engineering assistance, spare propulsion systems and parts, and production tooling. This award is one in a series of milestones for the F135 engine program, including exceeding 10,000 ground test hours as part of the system development and demonstration program; logging 51 successful flight tests and more than 54 flight test hours of the F135-powered CTOL F-35 aircraft; and completing 13 flights of the F-35B powered by Pratt & Whitney’s F135 STOVL propulsion system.

Rated at more than 40,000 pounds of thrust, the F135 is the most powerful fighter engine ever built. The technologically advanced F135 is an evolution of the highly successful F119 engine for the F-22 Raptor. By the time the F-35 enters operation, the F119 engines will have logged more than 480,000 flight hours. In addition, the F135 will have logged 16,000 flight hours and more than 17,000 ground test hours. The ground and flight test experience demonstrate the maturity and the associated reliability of the F135 engine for armed forces around the world.

The F135 STOVL propulsion system team consists of Pratt & Whitney, the prime contractor with responsibility for the main engine and system integration; Rolls-Royce of the United Kingdom, which provides lift components for the STOVL F-35B; and United Technologies Corp.’s Hamilton Sundstrand unit, provider of the engine control system and gearbox.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and building industries.

This press release contains forward-looking statements concerning future business opportunities. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to changes in the Lightning II funding related to the F-35 aircraft and F135 engines, changes in government procurement priorities and practices or in the number of aircraft to be built; challenges in the design, development, production and support of technologies; as well as other risks and uncertainties, including but not limited to those detailed from time to time in United Technologies Corporation's Securities and Exchange Commission filings.
