Air Force Plant 42 (AFP 42) is a federally owned military aerospace facility under the control of the Air Force Material Command (AFMC) in Palmdale, California. Aerospace contractors at Air Force Plant 42 share a common runway complex and either lease building space from the Air Force (commonly referred to as GOCO, or Government Owned Contractor Operated), or own their own building outright. There are eight separate production sites specially suited for advanced technology and/or "black" program projects. Currently the most well–known contractors at Plant 42 are Boeing, Lockheed Martin (home of the legendary Skunk Works), and Northrop Grumman. Plant 42 as of August 2010 has updated their operation status from GOCO (Government Owned Contractor Operated) to a DoD operated facility. Privately–run since 1954, the Air Force under the Obama administration chose to insource the contracted operations of the plant. Now it is run by DoD resources, with Detachment 1 in command.
