The Rockwell B-1 Lancer

The Rockwell B-1B Lancer traces its origins to the B-1A prototype strategic bomber of the 1970s. The basic B-1A design was much revised, and resulted in 100 production B-1B Lancers, the first of which flew in production form on 18 October 1984. The B-1B has variable geometry outer wing panels, some degree of stealthiness and is optimised for the low-level, high-speed penetration role against sophisticated air-defence systems with the aid of comprehensive countermeasures systems. The primary offensive system is the APQ-164 multi-mode radar, which includes a low-observable phased-array antenna for low-altitude terrain following and accurate navigation.
