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.
The Mark 27 was designed by the University of California Radiation Laboratory (UCRL; now Lawrence Livermore National Laboratory) starting in the mid-1950s.The basic design concept competed with the Los Alamos Scientific Laboratory (LASL; now Los Alamos National Laboratory) design that would become the Mark 28 / B-28 nuclear bomb and W28 warhead.
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 [31] 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 ...

It also was adaptable into a warhead (the W39) which would eventually be adaptable to a B-58 Hustler external weapons pod, the SM-62 Snark missile, and the PGM-11 Redstone missile. As the weapon now always contained all components needed to fire it, several safety systems were added to avoid inadvertent detonation, including safing pins that ...
