Jane's All The World's Aircraft 1987-88
NORTHROP ATB
During October 1981, it was reported that contracts totalling $7,300 million had been awarded to Northrop, to develop and build prototypes of an advanced technology (‘stealth’) bomber (ATB) to take over the B-lB’s penetration role during the final years of this century. No details are available officially, except that Northrop, as prime contractor, is being assisted by Boeing Aerospace, LTV (Vought) and General Electric Engine Group. However, the ATB has a flying-wing configuration, is expected to be smaller than the B-1B, and was reported to be scheduled to make its first flight in November 1987. Indications in mid-1986 were that the ATB would have four (F101?) engines, and a gross weight in the region of 158,760-170,100 kg (350,000-375,000 lb). In early 1986 Norlhrop’s Advanced Systems Division at Pico Rivera, California, had completed a full scale engineering mockup of the ATB. A scaled proof of concept vehicle is believed to have been flying since 1982. Subject to satisfactory flight testing, the USAF plans to acquire 132 ATBs in a $36,600 million programme, with first deliveries to Whiteman AFB, Missouri, in the early 1990s.
