The ZBGM-110A was one of the two finalists in the U.S. Navy's SLCM (Submarine-Launched Cruise Missile) competition of 1974-76. The other one was the General Dynamics ZBGM-109A, q.v. for further details about the SLCM program. The first attempt in February 1976 to launch a YBGM-110A prototype from a torpedo tube failed because of a tube malfunction, and on the second attempt, the missile's wing failed to deploy. Because the YBGM-109A had performed flawlessly on two launches, and was the less risky overall design, the U.S. Navy declared the BGM-109 the winner of the SLCM competition in March 1976, thus ending the BGM-110 development.

The YBGM-110A was powered by a Teledyne CAE Model 471-11DX turbofan engine and a solid-propellant rocket booster for launch. An unusual feature was its one-piece fiber-glass wing, which was stored longitudinally in the fuselage, and pivoted through 90 to protrude through slots high on the fuselage sides. The tail surfaces were three curved fins, which lay flush on the round fuselage before deployment.

Before the BGM-110 development program was cancelled, the designations YBGM-110B (for an anti-ship missile, equivalent in purpose to the BGM-109B) and YAGM-110A (for an ALCM version) had been reserved for projected variants.
