The Improved Fresnel Lens Optical Landing System (IFLOLS) is designed to give glide path information to pilots to help them land. The trailer is a TIG-welded, specialty manufactured variance of the MHU-141/M munitions trailer. It is used primarily by the Navy and Marines Corps.
The F-16 gun maintenance trailer is used to remove and install the gun from the F-16 aircraft's top access panel. Its unique design employs a hand-cranked crane that rotates 360 degrees for ease of use and includes cushioned storage areas for the guns to be safely secured and transported.
