Lockheed Spokesman at the Paris Air Show are sound a little prickly concerning the reported travails of the F-35. Euro's going their own way in developing their own stealth fighter, the Tempest, the well publicized deficiencies, weapons payload, hypersonic missiles on older airframes like the B-52, new competition from the UTC-Raytheon merger etc.they want to get these problems out of the headlines. So double quick on reporting & implementing these solutions.

Thirteen Category 1 deficiencies were found and reported by operators, according to the for-official-use-only documents Defense News obtained. Cat 1 is a label for problems that would directly impact safety or the mission. Those ranged from coating fixes; pressure anomalies in the cockpit that gave pilots ear and sinus pain; and washed-out imagery in the helmet-mounted display, among others.

The Air Force, Navy, and Marine Corps each fly a variant of the aircraft designed for different scenarios, from landing on conventional runways on land, to catching arresting cables on aircraft carriers, to landing like a helicopter on amphibious assault ships.

Responding to the Defense News article series, Lockheed Martin said each deficiency "is well understood, already resolved or on a near-term path to resolution."

"We've worked collaboratively with our customers, and we are fully confident in the F-35's performance and the solutions in place to address each of the items identified," the company said in a statement June 12, 2019.
