Pratt & Whitney Jet Engine to Power Long Range Strike Bomber (if GAO shoots down protest)

As the aerospace world anxiously awaits the Government Accountability Office’s verdict on whether to allow Northrop Grumman to begin construction on the Pentagon’s Long Range Strike-Bomber (LRS-B), new details help paint a clearer picture of who will build crucial parts and systems.


If Northrop builds LRS-B, GE Aviation will manufacture the primary and secondary power distribution systems, not the plane's engine, according to a source with knowledge of the program. GE was partnered with the Boeing-Lockheed Martin team on the power plant, the source said.

The news that GE is not the winning engine maker fuels speculation that Northrop's bomber will be powered by Pratt & Whitney engines. Although nothing is certain, some have hypothesized that LRS-B will use Pratt's F135 engines, according to a recent analysis by Jim McAleese.

The rumor is the engine is an ADVENT derivative with an F135 core.
