Lockheed Martin has hit a huge milestone in F-35 Joint Strike Fighter production.
However, that accomplishment, while outstanding, is complicated by the ongoing saga
surrounding the development and testing of Tech Refresh-3 (TR-3) hardware
configuration. TR-3 underpins the F-35's future capabilities, known collectively as Block
4. Delays with TR-3 mean that F-35s are being parked and not delivered after they are
constructed, waiting for these features. So is the case for the 1,000th F-35.
