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 Mark 4 nuclear bomb was an American implosion-type nuclear bomb based on the earlier Mark 3 Fat Man design, used in the Trinity test and the bombing of Nagasaki.With the Mark 3 needing each individual component to be hand-assembled by only highly trained technicians under closely controlled conditions, the purpose of the Mark 4 was to produce an atomic weapon as a practical piece of ordnance.
Their main program is to extend the life of the W76 warhead. [2] The main facilities of the National Nuclear Security Administration are: [9] The administrative headquarters known as the Albuquerque Complex; Lawrence Livermore National Laboratory in California which researches plutonium and houses the National Ignition Facility
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.
