Here’s a darkly humorous bit about the F-35. Even though it’s not yet in service, it seems that it’s been in development so long that some of its electrical components are already obsolete and hard or impossible to obtain. From the defense.gov website,
“Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Fort Worth, Texas, is being awarded a $10,019,765 modification to a previously awarded firm-fixed-price contract (N00019-13-C-0008) to exercise an option to procure additional diminishing manufacturing sources electronic components in support of the F-35 Lightning II aircraft.”
This happens to all ships and aircraft at some point during their service lives but not during development!
If we don't hurry, we're not going to have the parts to build these things.
I’d laugh if I wasn’t crying.
