W79

The W79 Artillery-Fired Atomic Projectile (AFAP), also known as XM753 (Atomic RA), was an American nuclear artillery shell, capable of being fired from any NATO 8 in (203 mm) howitzer e.g. the M115 and M110 howitzer. The weapon was produced in two models; the enhanced radiation (ERW) W79 Mod 0 and fission-only W79 Mod 1. Both were plutonium-based linear-implosion nuclear weapons.

• The Mod 0 was a variable yield device with three yields, ranging from 100 tons of TNT (420 GJ) up to 1.1 kt (4.6 TJ) and an enhanced-radiation mode which could be turned on or off
• The Mod 1 was fission-only with a fixed 0.8 kt (3.3 TJ) yield, corresponding with the maximum fission only yield of the Mod 0
