SHOP EQUIPMENT CONTACT MAINTENANCE (SECM)
THEORY OF OPERATION
The Army SECM provides a relatively large and weather resistant tool and repair parts container installed on the
HMMWV. The container assembly is composed of four primary components, along with appropriate attaching
parts and hardware. When installed on the HMMWV (an associated item of equipment (ASIOE) to the SECM
System), the unit becomes a highly mobile system capable of providing contact maintenance to all army aircraft.
The vehicle/container can be outfitted with tool sets from the New Aircraft Tool System (NATS), as well as repair
parts and other supplies in support of contact maintenance missions for all army aircraft. The contact
maintenance mission is to repair any downed aircraft, as far forward on the battle field as possible, thereby
returning the aircraft to it's mission or allowing a one time flight to a repair facility thereby avoiding destruction or
capture of the aircraft. The SECM Container is also storable off-vehicle, which allows the container to function as
a temporary storage facility for tools and repair parts.
