(two shell versions)
3AD M-110 Howitzer


Above: An M-110A2 Howitzer (and its predecessor, the M-110A1) had nuclear capability in the 3AD in the late 1970's and the 1980's when nuclear shells were under direct 3AD control (i.e., no longer limited to special V Corps artillery units). The M-33 shell was standard fission and had four different yields, ranging from less than 1 kiloton to less than 20 kilotons. Detonation was by mechanical time-delay airburst.

The W-79 shell was intended to replace the M-33 in the early 1980's, but the M-33 was still kept in service. The characteristics of the two shells complimented each other. Fielded in 1981, the M-79 was dual capable in Mode 0 as either a pure fission weapon (plutonium linear implosion) or in enhanced radiation mode (ER or "neutron bomb"). In Mode 1, it was standard fission only. Its yield range was variable: 100 tons to 1.1 kiloton in Mode 0 and 0.8 kiloton in Mode 1. Detonation was by proximity airburst or contact.

Only limited and specially trained small units in Division Artillery would have access to these shells.
