Engine maker Pratt & Whitney is leaving San Diego at a cost of 530 jobs, consolidating its operations as defense spending contracts.
The defense contractor announced Thursday that it plans to close its AeroPower facility in San Diego over the next two years. AeroPower makes auxiliary power units for military and commercial airplanes.
The company says the move is needed to maintain competitiveness.
AeroPower's military business will move to Pratt & Whitney's Military Engines organization. The company is considering relocating operations to existing facilities in Florida, Georgia and Texas.
The commercial side will go to Pratt & Whitney Canada, with much of the actual work being done in Poland.
