Northrop Corp.’s Ventura division, which produces unmanned aeronautical vehicles, will become a unit of its aircraft division. The realignment will bring the manufacturing resources of its fighter aircraft operations to its fast-growing unmanned tactical weapon systems division, the company said. The weapons division, with 2,300 employees in Newbury Park, is the prime contractor for the new Tacit Rainbow radar-killing missile system and the BQM-74C, the Navy’s principal target system. The aircraft division, with about 14,000 employees in Hawthorne and El Segundo, builds major elements of the F/A-18 strike fighter and the fuselage for the Boeing 747, and is a prime contractor for prototype development of the Air Force’s Advanced Tactical Fighter.
