Lockheed stepped in the doodoo with their typical whining over contract terms. The only diff in this case is that they couldn't even wait until the RFP was done and awarded before whining:
Then, in February, Lockheed Martin
filed a protest with the Government Accountability Office over a disagreement over technical data rights—a rare legal dispute filed before the service had decided on the winner. Lockheed argued that, in its solicitation, the Air Force used too broad a definition of “operations, maintenance, installation and training data,” which by statute is turned over to the government for its unlimited use.
Which anyone who knows Lockheed can decode as; "the customer ignored our pre-written RFQ we gave them that only Lockheed could source". Glad I don't work for them anymore, and congrats to the winning team. I hope it's a success. I've never flown the 139(way after my stick time) but have heard good things.
