Defense contractor Lockheed Martin plans to cut 1,200 jobs to lower costs as it combines two units, according to AP. The company says employees who will lose their jobs will be notified by early April. Lockheed announced in November its plans to combine two units in its electronics systems business _ the former Maritime Systems & Sensors and Systems Integration - Owego businesses. The newly combined unit, Mission Systems & Sensors, will provide services to maritime forces. Lockheed is based in Bethesda.
