East Hartford aerospace manufacturer Pratt & Whitney will produce 38 additional fighter jet engines for the Pentagon under a modified contract, it announced.
The F135 propulsion systems will power the F-135 Lightning II jet.
Pratt, a subsidiary of United Technologies, will supply about half of the engines to the U.S. Air Force and the rest will go to the Navy and the Marines.
It’s the sixth lot of engines under the contract, which this week grew $508 million to a total value of $1.1 billion.
Pratt said the unit prices of the 32 common configuration engines have come down by 2.5 percent from the previous batch. Six short-takeoff-and-vertical-landing engines are 9.6 percent cheaper, it said.
Deliveries of the 38 engines will start before yearend.
