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.
