B28

The B28 was a thermonuclear weapon developed by the United States. It entered service in the late 1950s and was produced in various yields. The B28 was a versatile weapon, designed for a range of delivery methods including bombs, air-to-ground missiles, and naval depth charges. Its design incorporated a multi-stage thermonuclear process, allowing for variable yield options, which meant the explosive power could be adjusted depending on the mission requirements.

The B28 saw widespread deployment across the U.S. Air Force, Navy, and Marine Corps. It was a key component of the U.S. nuclear arsenal for several decades, remaining in service until the early 1990s. The weapon's modular design facilitated upgrades and modifications throughout its lifespan. Its flexibility and relatively compact size made it suitable for numerous strategic and tactical scenarios. Production ceased in the early 1980s, and decommissioning was completed by 1991. The B28 represented a significant step in the miniaturization and variable-yield capabilities of nuclear weapons during the Cold War era.
