The Pentagons top weapons buyer is backing calls to restore a valve on Lockheed Martins F-35 jet that improves the fighters chances to survive a hit from a high-explosive round.
Adding an improved valve would result in the aircraft being fully compliant with its operational requirements, Frank Kendall, the undersecretary for acquisition, wrote a lawmaker last month in a previously undisclosed letter.
The 2-pound valve system was part of 43 pounds of equipment removed in 2008 to save weight on the F-35, designed and built in west Fort Worth. The valve is intended to shut off the flow of a flammable liquid used to cool avionics.
A computer analysis of the pared-down F-35 design last year determined that its vulnerability to fires ignited by enemy bullets or missile fragments increased 25 percent from an assessment before the equipments removal, according to data from the Pentagons weapons-testing office.

That can't end well.

(21,320 posts)3. Exactly what I was thinking.
Maybe, just maybe, replace the coolant with something that's NOT flammable?

This is the very first time I've even heard of liquid cooled avionics.
