If you want to go with that name I'm just gonna leave the thought of perhaps dropping the "missile" in "variable missile launch system" since the 1M, 2M, 3M, and 4M have the what is being launched, that way it cuts down on redundant uses of the word missile, that would make it just "variable launch system - 1 Missile", etc... Also, for the targeting computer version you could add a /T for targeting to the acronym so it could read VLS/T or VMLS/T. Maybe I'm just too into the way Star Wars uses acronyms, anyways, just a thought for you to, maybe, chew on. Loving the progress by the way, getting really excited to see how everything turns out!
