One of three prototype "Glomb" models ordered by the Navy, the LBT suffered from technical and performance difficulties, and was cancelled early in production, none of the aircraft seeing operational service.

[2] Following the Navy's initial evaluation, the Glomb comcept was deemed to be worth developing further, and the project was given official status by the Bureau of Aeronautics in April 1941.

[3] The LBT-1 featured a high, strut-braced wing and tricycle landing gear; the aircraft was designed to carry a 2,000 pounds (910 kg) bomb as a warhead.

In addition to its TV-and-radio remote guidance system, the LBT-1 retained a cockpit, allowing a pilot on board to fly the aircraft on training and evaluation flights.

[3] The Navy's contract called for the production of 100 of each type of Glomb; however, by October 1944, trials were beginning to indicate that the low expected performance of the glider bomb was a liability, and the Piper LBP-1 and LBE-1 were considered superior.
