The MHU-7/M Bomb Lift Trailer is used to transport bombs from a storage site to an aircraft. Shown here are training versions of MK 28RI thermonuclear bombs secured to a "clip-in" assembly. The assembly is mounted on a cradle transported by the MHU-7/M. After being moved into position beside the B-52's bomb bay, the castoring wheels of the trailer permit it to be moved sideways under the aircraft. The trailer's hydraulic actuators then lift the entire four bomb clip-in assembly into position in the bomb bay.
