The Pentagon has awarded Lockheed Martin a multi-billion dollar contract for 255 F-35 fighter jets.
One hundred and six of the jets are for the US military - 64 F-35As for the Air Force, 26 F-35Bs for the Marines, and 16 F-35Cs for the Navy.
The remainder are believed to be for foreign customers.
Lockheed Martin will receive a $6 billion advance for the order which is scheduled to be completed by March 2023.
Most of the work on the jets will be performed in the US, with some being carried out in countries including Britain and Italy, with around 15% of each jet will be produced in the UK.
Britain has committed to purchasing 138 of the B variant and is set to have bought 48 by 2025.
The UK now has 16 of a planned 138 F-35B jets.
F-35B aircraft landed on the deck of the UK's new aircraft carrier, HMS Queen Elizabeth for the first time in September.
