Aerojet Rocketdyne
Aerojet Rocketdyne is an American rocket and missile propulsion manufacturer. Headquartered in Sacramento, California, the company is owned by Aerojet Rocketdyne Holdings. Aerojet Rocketdyne was formed in 2013 when Aerojet and Pratt & Whitney Rocketdyne were merged, following the latter's acquisition by GenCorp from Pratt & Whitney. On April 27, 2015, the name of the holding company, GenCorp, was changed from GenCorp, Inc. to Aerojet Rocketdyne Holdings, Inc. As part of a $4.4 billion acquisition, struck on December 20, 2020, Lockheed Martin is to take over Aerojet Rocketdyne, pending regulatory approvals. On February 17, 2021, Raytheon objected to the acquisition, citing a reduction of competition for rocket boosters impacting the company's supply line. Federal Trade Commission announced 25 January 2022 that the commission is blocking Lockheed Martin's acquisition of Aerojet Rocketdyne.
