The U.S has offered Korea 60 F-35 Joint Strike Fighter Conventional Take Off and Landing (CTOL) aircraft at a subsidized cost of $10.8 billion with each jet prices at $180 million.

This is in stark contrast to the differing prices to allies around the world. Japan’s acquisition of 42 F-35As (4 + 38 on option) aircraft will approximately cost $10 billion about $238 million per aircraft. And Israel, has been offered 75 F-35s for $15.2 billion about $202.6 million for each jet.

The Pentagon has yet to issue a statement on the varying price tags.

Meanwhile, the sale to Korea will include the Pratt & Whitney F-135 engines, and (9) Pratt & Whitney F-135 engines are included as spares.

Other aircraft equipment includes: Electronic Warfare Systems; Command, Control, Communication, Computer and Intelligence / Communication, Navigational and Identification (C4I/CNI); Autonomic Logistics Global Support System (ALGS); Autonomic Logistics Information System (ALIS); Full Mission Trainer; Weapons Employment Capability, and other Subsystems, Features, and Capabilities; F-35 unique infrared flares; reprogramming center; F-35 Performance Based Logistics.

Reacting to the announcement, Lockheed Martin says that it is pleased that the formal Congressional notification process is now under way, but added that the competing bids are still under evaluation by Korean officials and that price discussions are "on-going".
