San Diego County stands to get approximately $450 million worth of work from the Pentagon’s latest order for F-35 Lightning II aircraft, also known as the Joint Strike Fighter.

The Defense Department announced on Nov. 14 that it made the $22.7 billion order for 255 aircraft in Lot 12. Some 2 percent of the money will flow to San Diego.

Lockheed Martin Corp. (NYSE: LMT) is prime contractor for the aircraft.

Much of the work will go to Northrop Grumman Corp. (NYSE: NOC) which produces software defined radios for the advanced fighter in San Diego’s Carmel Mountain Ranch neighborhood. The radios handle communication, navigation and other functions.

The 255 aircraft in the latest order will go to the U.S. Air Force, U.S. Marine Corps, U.S. Navy and to allies of the United States.

Work is expected to run through March 2023.

The majority of work on the F-35 aircraft — some 57 percent — is done in Fort Worth, Texas.
