PROCUREMENT: Pentagon stops accepting Lockheed F-35 jets over repair cost dispute.

Last year, the Pentagon stopped accepting F-35s for 30 days after discovering corrosion where panels were fastened to the airframe, an issue that affected more than 200 of the stealthy jets. Once a fix had been devised, the deliveries resumed, and Lockheed hit its target aircraft delivery numbers for 2017.

But deliveries were paused again over a dispute as to who will pay for what will likely be a complex logistical fix that could require technicians to travel widely to mend aircraft based around the world, said the people, who spoke on condition of anonymity because they were not authorized to speak publicly about the matter.

When the Pentagon stops taking delivery of F-35s, foreign customers can also be affected. So far at least two foreign governments have stopped accepting F-35s as a result of this issue, two of the sources said.

More tough negotiations with Lockheed, please.
