Lockheed Martin F-35 Lightning II procurement is the planned selection and purchase of the Lockheed Martin F-35 Lightning II, also known as the Joint Strike Fighter (JSF) by various countries.
The F-35 Lightning II was conceived from the start of the project as having participation from many countries, most of which would both contribute to the manufacture of the aircraft and procure it for their own armed forces. While the United States is the primary customer and financial backer, the United Kingdom, Italy, the Netherlands, Canada, Turkey, Australia, Norway and Denmark have agreed to contribute US$4.375 billion toward the development costs of the program. Total development costs are estimated at more than US$40 billion (underwritten largely by the United States), while the purchase of an estimated 2,400 planes is expected to cost an additional US$200 billion. Norway has estimated that each of their planned 52 F-35 fighter jets will cost their country $769 million over their operational lifetime. The nine major partner nations, including the U.S., plan to acquire over 3,100 F-35s through 2035, which, if delivered will make the F-35 one of the most numerous jet fighters.
There are three levels of international participation. The levels generally reflect the financial stake in the program, the amount of technology transfer and subcontracts open for bid by national companies, and the order in which countries can obtain production aircraft. The United Kingdom is the sole "Level 1" partner, contributing US$2.5 billion, which was about 10% of the planned development costs under the 1995 Memorandum of Understanding that brought the UK into the project. Level 2 partners are Italy, which is contributing US$1 billion; and the Netherlands, US$800 million. Level 3 partners are Canada, US$475 million; Turkey, US$195 million; Australia, US$144 million; Norway, US$122 million and Denmark, US$110 million. Israel and Singapore have joined as so-called "security cooperative participants" (SCP).
