By the time the warhead entered production in April 1960, it also incorporated the firing set from the Mod 1 warhead. [ 10 ] The Mark 49 Mod 4 only came in the Y2 yield option, [ 11 ] was 2.1 inches (53 mm) longer than the original warhead, and weighed 1,640 pounds (740 kg) and 1,732 pounds (786 kg) without and with ablative material respectively.

A B61 nuclear bomb in various stages of assembly; the nuclear warhead is the bullet-shaped silver canister in the middle-left of the photograph.. A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.
Grable was the second of only four gun-type warheads ever detonated (the first was Little Boy, the last two were test firings of the W33; all other atomic weapons were implosion-type weapons). The shell, designated a Mark 9 nuclear weapon, had a diameter of 280 mm (11.02 in), was 1380 mm (54.4 in) long and weighed 364 kg (803 lb).
Detonation was by time-delay fuze, although the fuzing mechanism would not arm the warhead until engine burn-out, to give the launch aircraft sufficient time to turn and escape. However, there was no mechanism for disarming the warhead after launch. Lethal radius of the blast was estimated to be about 300 metres (980 ft).
The warhead contains TATB-based LX-17 polymer bonded explosive in its primary stage, which is an insensitive high-explosive (IHE) designed to reduce the chance of detonation in an accident. [ 1 ] [ 2 ] Other explosive present in the warhead include ultra-fine powdered TATB (UF-TATB) and LX-16, [ 2 ] a PETN-based conventional polymer-bonded high ...
The experiment, part of the Operation Grommet nuclear test series, tested the unique W71 warhead design for the LIM-49 Spartan anti-ballistic missile. [2] [3] With an explosive yield of almost 5 megatons of TNT (21 PJ), the test was the largest underground explosion ever detonated by the United States. [4]

The W71 nuclear warhead was a US thermonuclear warhead developed at Lawrence Livermore National Laboratory in California and deployed on the LIM-49A Spartan missile, a component of the Safeguard Program, an anti-ballistic missile (ABM) defense system briefly deployed by the US in the 1970s.
