Luke AFB gets temps in the 115+ degree range in summer and much higher on air strips.

Oh, but they are:

Quote:
The F-35 channels its strong thermal loads, accumulated by the powerful avionics and sub-systems on-board, as well as the engine, into its fuel. So really, the fuel works as a giant heat sink. If the fuel is already warm upon start-up, there is less capacity to exchange the heat from their aircraft's simmering systems. Therefore the jet must shut down or risk overheating. A clever design that most likely lightens up the jet and leaves extra room for weapons and fuel, but one that may have very little room for adaptation.

I love that chart, but then I'm unapologetically biased about the 'Hog.

This lack of CCIP is bad juju.

I think it was the PR bundling.

The Marines wanted CAS and VTAL
The Navy wanted carrier based
The AF didn't know what they wanted, but it had to be fast & expensive

At least that's what my insider tells me.. :munchin

I found an alternative to the F-35.

Carries just about as much for CAS.
Can do vertical landings.
Fast enough for the AF.
Uses new airborne launch craft, so the boys can get a good nights sleep on the way to the target AO.

AND cheaper. :lifter

Anything painted in the color white absorbs less radiant heat from sunlight than does anything painted in black or very dark colors.

When ambient temps get to the century mark? It does make a difference.
I work outdoors & that's one of the reasons I keep my tools painted.

Seems strange that the testing of the F-35 and the current active wing is based in Edwards AFB, in the middle of the desert. Yet the problem is just now being recognized??

Not quite on the Apaches.

allows the Army to transfer not more than 48 Apache helicopters from the Army National Guard to the regular Army.
48 Apaches is a lot. Texas has been spending tons of political capital to try and keep them but this might be a nail in the coffin. Thanks for the link.

New U.S. Stealth Jet Can’t Fire Its Gun Until 2019
 
http://www.thedailybeast.com/article...ntil-2019.html

The JSF won’t be completely unarmed. It will still carry a pair of Raytheon AIM-120 AMRAAM long-range air-to-air missiles and a pair of bombs. Initially, it will be able to carry 1,000-pound satellite-guided bombs or 500-pound laser-guided weapons. But those weapons are of limited utility, especially during close-in fights.

Two bombs and no bullets!!
CAS ready?

The F-35 is going to continue to be a polyp until the contractor is taken out of the acquisition decision process and the warfighter is put back in. You think that will happen any time soon??

I'm not sure it's so much the contractor as it is the program office with too many chefs in the kitchen. When I was I was on active duty at the F/A-18 Weapons School, we had several meetings with some of the JSF engineers and loggies to discuss the issues with weapons loading on aircraft carriers....
There was a ton of issues related to safety practices that they were not even aware of .....

Not that it is related to the gun in particular but that program felt like a design by committee with few of those that would maintain, load, and support it being involved...

This seems to follow a similar track to the Osprey in that they will make it work at any cost.
