The operational IM-99A missiles were based horizontally in semi-hardened shelters, nicknamed "coffins". After the launch order, the shelter's roof would slide open, and the missile raised to the vertical. After the missile was supplied with fuel for the booster rocket, it would be launched by the Aerojet General LR59-AJ-13 booster. After sufficient speed was reached, the Marquardt RJ43-MA-3 ramjets would ignite and propel the missile to its cruise speed of Mach&nbsp;2.8 at an altitude of {{convert|20000|m|ft|abbr=on|order=flip}}.<ref name="Gibson"/>

When the Bomarc was within {{convert|16|km|mi|abbr=on|order=flip|round=5}} of the target, its own Westinghouse AN/DPN-34 radar guided the missile to the interception point. The maximum range of the IM-99A was {{convert|400|km|mi|abbr=on|order=flip}}, and it was fitted with either a conventional high-explosive or a 10&nbsp;kiloton W-40 nuclear fission warhead.<ref name="Gibson"/>

The Bomarc relied on the [[Semi-Automatic Ground Environment]] (SAGE), an automated control system used by [[North American Aerospace Defense Command|NORAD]] for detecting, tracking and intercepting enemy [[Bomber|bomber aircraft]]. SAGE allowed for remote launching of the Bomarc missiles, which were housed in a constant combat-ready basis in individual launch shelters in remote areas. At the height of the program, there were 14 Bomarc sites located in the US and two in Canada.<ref name="Gibson"/>
