Telegraph: "F-35 Fighter 'Hit By Software And Reliability Problems'"

#2
Fighter software problems aren't new; Saab JAS39 Gripen Crash 1993 - YouTube .

The Gripen is now an excellent lightweight fighter.

Anyone know what
Reuter

remains vulnerable to propellant fires sparked by missile strikes.
means? If a missile's that close, the last thing you'd worry about is sparks; or is it just crap phrasing? If "strike" means "attack" rather than another word for "hit", I suppose launching your own missile and setting fire to your aeroplane could sod your sortie up.

I'm not an aviation expert but just reading it sounds as though the fuel system isn't suppressed (which I think is why the Nimrod exploded so quickly in Helmand and why the C-130s were upgraded as an incident in Iraq) - there are systems that seal/suppress the internal fuel supply. May well be entirely wrong though.

Odd, given the issues related to airworthiness that this isn't a feature - which makes me suspect I'm wrong.

You are talking about Explosive Suppressant Foam (ESF). They fill the tanks with a jigsaw of foam blocks. Also flame arrestors, and fuel tank inerting ( removal of oxygen by replacing it with nitrogen). C130's are now my day job.

Haddon Cave (nimrod) caused a whole world of hurt!

It's about the only thing I could stretch my mind to with regard to that Reuters quote. I do find it odd that F35II hasn't had that from build, in fact I find it impossible to imagine. So, I think there must be another explanation.

Is it that the F35 goes like **** and is not expected to take a hit except for a missile which would render the inerting rather pointless. Weight and space will be at much more of a premium on this than a C130 or nimrod.That is just a thought not a matter of fact.
