WASHINGTON (AP) — For the dozen lawmakers tasked with producing a deficit-cutting plan, the threatened "doomsday" defense cuts hit close to home.

The six Republicans and six Democrats represent states where the biggest military contractors — Lockheed Martin, General Dynamics Corp., Raytheon Co. and Boeing Co. — build missiles, aircraft, jet fighters and tanks while employing tens of thousands of workers. The potential for $500 billion more in defense cuts could force the Pentagon to cancel or scale back multibillion-dollar weapons programs. That could translate into significant layoffs in a fragile economy, generate millions less in tax revenues for local governments and upend lucrative company contracts with foreign nations.

The cuts could hammer Everett, Wash., where some of the 30,000 Boeing employees are working on giant airborne refueling tankers for the Air Force, or Amarillo, Texas, where 1,100 Bell Helicopter Textron workers assemble the fuselage, wings, engines and transmissions for the V-22 Osprey tilt-rotor aircraft.
