JSF engine passes key test

EAST HARTFORD, Conn. – The Pratt & Whitney’s F135 engine that powers the F-35 Joint Strike Fighter has completed altitude qualification ground testing, the final testing that demonstrates the operability and performance required for conventional take-off and landing and carrier variant initial service release (ISR). ISR is the government’s recognition that the F135 engine is ready for operational use and clears Pratt & Whitney to deliver and field production F135 engines.
