LTV was selected with General Dynamics to compete in a fly-off of their competing submarine launched cruise missile designs. The LTV version was designated YBGM-110 with the GD missile designated YBGM-109.
There is an excellent article here: Vought Org Website so I won't republish all that information in this post. The LTV missile failed on it's first two test flights, the first attributed to the Navy, the second to a programming error. The GD design did not suffer a similar fate. The engine that the Navy selected for the LTV missile was not as a mature, nor successful program as the William offering was at competition time.
Here are a few publicity images of the ALCM version mounted on the right wing of a factory fresh A-7E aircraft. Images from VAHF collection.
