1 Lancer The Rockwell B 1 Lancer, commonly known as the Boone, is a supersonic variable strategic heavy bomber used by the United States Air Force. The plane, developed by Rockwell International, first flew in the 1970s as a 1A model and was designed for nuclear strikes at Mach 2.2. After the program was temporarily canceled due to skyrocketing costs and changing security priorities, the project was revived in 1981 under the Reagan administration as B1B. This updated version was optimized for high-speed, low-altitude infiltration missions and was designed to fly below enemy radar networks at Mach 1.25.
