The escutcheon portrays the coat of arms of the State of Maryland and signifies the home location of the unit. The crossed jousting lances reflect the military preparedness of the squadron and allude the Maryland state sport. Background: Designed by Lt Col Ronald James and approved for the 135th Tactical Airlift Squadron on 3 October 1990. Redesignated for the 135th Airlift Squadron in 1992. The motto, "Baltimore's Best" was suggested by Master Sgt. Lee Cherry and arose from the unit having been recognized by the Baltimore Is Best Committee on 18 Feb 1987. This insignia superseded one approved by the Air Force for the squadron in October 1960.
