B-1b

B-1B "Lancer" is a bomber developed by Rockwell Company and developed by Boeing Company. At the end of 1970s, the U.S. Air Force tried the prototype of B-1A, and the main operational mode of B-1A was supersonic high-altitude penetration. However, due to the change of the U.S. Air Force's strategy and the high-altitude penetration mode, it was not enough to cope with the powerful Soviet air defense firepower network, so the A-type was quickly dismounted. B-1B can break through enemy lines with supersonic speed and stealth. At present, B-1B does not undertake the task of nuclear strategic deterrence, but there is no doubt that it has strong nuclear strategic strike capability.
