In an April 15, 2006, article by Walter Pincus in the Washington Post, [23] Linton F. Brooks, administrator of the US National Nuclear Safety Administration, the US nuclear weapon design agency within the United States Department of Energy, announced that two competing designs for the Reliable Replacement Warhead were being finalized by ...
Lawrence Livermore engineers have hinted in prior press reports that the Reliable Replacement Warhead design that they were preparing might be based on the W89 warhead design. On March 2, 2007, the NNSA announced that the Lawrence Livermore National Laboratory RRW design had been selected for the initial RRW production version. [2] One of the ...

The laboratory is located on a 1 square mile (2.6 km 2) site at the eastern edge of Livermore. It also operates a 7,000 acres (28 km 2) remote experimental test site known as Site 300, situated about 15 miles (24 km) southeast of the main lab site. LLNL has an annual budget of about $2.7 billion and a staff of nearly 9,000 employees. [8]
The M51.1 missiles are intended to be replaced with the new M51.2 warhead beginning in 2016, which has a 3,000 kilometres (1,900 mi) greater range than the M51.1. [ 38 ] France has about 60 air-launched missiles tipped with TN 80 / TN 81 warheads with a yield of about 300 kt (1,300 TJ) each.
It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the same design). The Mark 15 was the first lightweight US thermonuclear bomb.
[2] 200 Mk 17s and 105 Mk 24s were produced, all between October 1954 and November 1955. The Mark 17 and Mark 24 were identical in all respects save for the design of their primary section. [ 2 ] They were the largest nuclear weapons ever put into service by the United States; only the Convair B-36 Peacemaker was capable of carrying them.
The warhead was initially manufactured from 1978 to 1987 and designed by Los Alamos National Laboratory.It was initially fitted to the Trident I SLBM system, but after the Rocky Flats plant where its successor the W88 was being made was shut down in 1989 after a production run of only 400 warheads, it was decided to transfer W76 warheads to Trident II.
