After being grounded for a while and missing out on both the Farnborough International Airshow and RIAT 2014 in the United Kingdom, the US has re-assumed flight tests again with its Lockheed F-35 Lightning II stealthy fighter jets. On 30 July 2014 a F-35B completed wet runway and crosswind testing at Edwards AFB in California, as part of the work-up to get the type towards
Initial Operational Capability (IOC) certification for its customer: the US Marine Corps.
The testing, completed in 37 missions during a 41-day period. All testing was performed with BF-4, normally based at Naval Air Station Patuxent River, Maryland.
Other F-35s continued flying as well, with F-35C CF-1 and F-35A AF-4 both achieving 500 flight hours, and F-35C CF-5 reaching a 100 flight hours. The USMC still hopes to get the type to its initial operational capability in August 2016, the US Air Force and US Navy are hoping for 2018. Many other countries have bought or will buy the F-35 as well, which has become the biggest 5th generation fighter jet program of the world.
