The U.S. Department of Defence and Lockheed Martin finalized the eighth F-35 Low Rate Initial Production (LRIP-8) contract  for 43 F-35 Lightning II airframes valued at $4.7 billion, including $0.5 billion of Advance Procurement funding that was announced at the time of award. The 43 airframes include 29 jets for the United States and 14 for five international countries. This agreement reflects an average airframes unit cost approximately 3.5 percent lower than the LRIP 7 contract signed in 2013 and a 57 percent reduction since LRIP 1.

U.S. LRIP 8 per variant airframe unit prices (not including engine cost) is as follows:   19 F-35A CTOL – U.S. Air Force – $94.8 million/airframe, 6 F-35B STOVL – U.S. Marine Corps – $102.0 million/airframe, 4 F-35C CV – U.S. Navy (3) and U.S. Marine Corps (1) – $115.7 million/airframe
