In an important program milestone enabling U.S. Marines Corps Initial Operational Capability (IOC) certification, the Lockheed Martin [NYSE: LMT] F-35B recently completed required wet runway and crosswind testing at Edwards Air Force Base, California.

“This testing is absolutely critical to 2B flight software fleet release and the Marine Corps’ IOC,” said J.D. McFarlan, Lockheed Martin’s vice president for F-35 Test & Verification. “Collectively, the results support clearing the 20 knot crosswind envelope for Conventional Take Off & Landings (CTOL), Short Take Offs (STO) and Short Landings (SL), with ideal handling quality ratings and meaningful improvement over legacy 4th generational fighter aircraft.”

The testing, completed in 37 missions during a 41-day period, achieved 114 test points, including  48 of 48 wet runway test points, four of four performance STOs, 12 of 18 unique flight test conditions for STO, 19 of 23 unique flight test conditions for SLs and all directional control and anti-skid wet runway testing. All testing was performed with BF-4, based at Naval Air Station Patuxent River, Maryland.
