Pratt & Whitney’s F135 engine for the F-35 Lightning II Joint Strike Fighter has amassed more than 6,000 hours of testing system development and demonstration ground testing, in addition to the more than 3,600 hours logged during the concept demonstration phase of the F-35, according to a company press release. P&W, which recently supervised a full after-burner test, says the engine is ready for F-35 taxi testing slated for later this fall.
The Space Development Agency says it’s on track to issue its next batch of missile warning and tracking satellite contracts this month after those awards were delayed by the Pentagon’s decision to divert funds from the agency to pay troops during this fall’s prolonged government shutdown.
