The Reliable Replacement Warhead (RRW) was a proposed new American nuclear warhead design and bomb family that was intended to be simple, reliable and to provide a long-lasting, low-maintenance future nuclear force for the United States.
W89 nuclear warhead W89 warhead (top) The W89 was an American thermonuclear warhead design intended for use on the AGM-131 SRAM II air to ground nuclear missile and the UUM-125 Sea Lance anti-submarine missile. What was to become the W89 design was awarded to the Lawrence Livermore National Laboratory in the mid-1980s.
Because there is concern that it will become increasingly difficult to maintain high confidence in the current warheads for the long term, the Department of Energy/National Nuclear Security Administration initiated the Reliable Replacement Warhead (RRW) Program. RRW designs could reduce uncertainties, ease maintenance demands, and enhance ...

By 1960, with the W47 warhead [30] deployed on Polaris ballistic missile submarines, megaton-class warheads were as small as 18 inches (0.46 m) in diameter and 720 pounds (330 kg) in weight. Further innovation in miniaturizing warheads was accomplished by the mid-1970s, when versions of the Teller–Ulam design were created that could fit ten ...
The W39 warhead was 35 inches (89 cm) in diameter and 106 inches (270 cm) long, with a weight of 6,230 pounds (2,830 kg) to 6,400 pounds (2,900 kg). It was essentially identical to the Mark 39 bomb, but lacked its parachute, fins, and "false" nose.
Exploded diagram of the Mk21 reentry vehicle for the W87 [clarification needed]. The W87 is an American thermonuclear missile warhead formerly deployed on the LGM-118A Peacekeeper ("MX") ICBM. 50 MX missiles were built, each carrying up to 10 W87 warheads in multiple independently targetable reentry vehicles (MIRV), and were deployed from 1986 to 2005.
