Alcoa announced a contract to supply titanium for Lockheed Martin’s F-35 Lightning II aircraft program, also known as the Joint Strike Fighter (JSF). Under the contract, Alcoa becomes the titanium supplier for airframe structures for all three variants of the F-35 over nine years, from 2016 to 2024. At current projected build rates, the contract has an estimated value of approximately $1.1 billion. Alcoa will supply titanium plate and billet from several operations gained through its acquisition of RTI International Metals. The titanium will be used to manufacture airframe structures for all three F-35 JSF variants. Under a different existing contract, Alcoa will use the metal to forge all of the largest titanium bulkheads for the CTOL variant at its Cleveland, Ohio, operations.
