Project Tom-Tom was originated by the United States Air Force’s Strategic Air Command as a way to provide its long range heavy bomber fleets with a fighter umbrella by towing them on semi-fixed wing links.

The concept of the MX-1018, the programs official call-sign, was devised from the FICO (Fighter Conveyor) system. A program initiated by the US Air Force in the 1950s to test the feasibility of utilizing a B-29 Superfortress bomber as a ‘mother ship’ from which a pair of Republic’s F-84 Thunderfalsh fighters would operate. FICO became fully operational in 1955, but only a handful of missions were ever flown.

In the Tom-Tom structure, the parasite fighter plane would shut down its engine to save fuel while it’s been towed. It will restart and detach from the moving airplane to intercept enemy aircrafts, rejoining the bomber once it has accomplished the mission.

For this configuration, two F-84Ds (versions 48-641 and 48-661) from the BASUT based at Wright-Patterson AFB in Ohio were especially modified to carry a lance-like structure on their port and starboard wingtips platforms. The re-configurated aircraft was given the EF-84D designation.
