Lockheed Martin has received a $237.7 million contract modification to a fixed-price-incentive-fee F-35 Joint Strike Fighter (JSF) production contract.

The money is for making configuration changes as a result of the JSF developmental test effort. There are hardware and software modifications that need to be made on the 32 Low Rate Initial Production (LRIP) IV jets that Lockheed is building for the US Department of Defense (DoD) and foreign partners.

The contact modification "increases the concurrency cap" for all three F-35 variants. "The concurrency cap establishes the threshold at or under which the contractor is obligated to incorporate government-authorized changes," reads a DoD release.

Lockheed says, "This money could pay for items already identified or fund future items as well, up to the new cap limit."

Of the $237.7 million, the Department of the Navy is paying for $153.2 million; another $69.4 million comes from the US Air Force. The United Kingdom is paying $8.2 million and the Netherlands $6.94 million.
