Rockwell B-1 Lancer

The Rockwell B‑1 Lancer, introduced in the mid‑1970s, is a supersonic strategic bomber that epitomizes Cold‑War era innovation. Developed by Rockwell International’s aerospace division—later associated with Rockwell Automation’s engineering heritage—the program began in 1970 as the Advanced Strategic Air Command (ASAC) project. After a protracted design competition, the first prototype rolled out in 1974 and entered operational service with the United States Air Force in 1986. The Lancer’s hallmark is its variable‑sweep wing, which retracts for high‑speed dash and extends for low‑altitude maneuverability, granting a top speed of Mach 1.2 and a combat radius exceeding 3,000 nautical miles. It carries up to 75,000 pounds of conventional or nuclear ordnance, supported by an integrated avionics suite that includes terrain‑following radar, digital flight control, and stealth‑reducing shaping. Over three decades, the B‑1 has been upgraded through the B‑1A, B‑1B, and B‑1C blocks, transitioning from nuclear deterrent to a primary conventional strike platform. Its ability to deliver precision‑guided munitions at low altitude and high speed reshaped modern air‑power doctrine, cementing the B‑1 Lancer as a cornerstone of United States strategic aviation. Today over 100 B‑1s remain in service, regularly upgraded with modern avionics and precision weapons.
