The issue occurs when a lightly loaded F-35C’s landing gear nose strut is compressed while the jet throttles up, right before launch. As the catapult fires and the hold back bar is released, the jet is rapidly pulled forward, during which time the strut oscillates violently up and down. The bouncing continues as the aircraft proceeds down the catapult track at increasing speed.

I've heard Lockheed Martin just needs another 2 or 3 years to fix the problem. (*Sheesh*. Why couldn't they employ a suspension lockout much like they do on mountain bikes to stop suspension oscillation.)

I assume the jet could spit the shuttle without proper end speed??? Seems like an easy fix is to have a full bag of gas. But I wonder if that is heavy enough, maybe it needs external stores to reach optimum launch weight.

Problem with heavy cat shot is reduced service life or TBO as they say in GA.

A problem I see... We got away from SE airplanes after the A-4. Probably every navy pilot on this site who flew two engine airplanes has shut one down once in a career due to high oil temp, low oil pressure, FOD ingestion, looking for the upgraded landing grade at the end of a line period (wait did I say that out loud?).

My point, F35 as far as I can tell has one engine. There is no gliding of course to an aircraft carrier. Lessons learned from the 70s and 80s were not part if this plan.

The tailhook being engineered under the two main landing wheels also tells me that navy pilots didn’t have a say in the design. The wheels pushed the cross deck pendant (wire) down causing a hookskip. I think it has been fixed?
