Are you sure about that. It's really small for a missile boat. It is certainly too small for ballistic missiles. American missile boats are over 500 feet long, about 40 feet high and displace over 18,000 tons. Russian boats are in the same size range (some slightly larger, some slightly smaller) On the other hand, the figures I've seen for this boat are less than half the length, about 24 feet high, and displacing about 2700 tons.
Line 3 "Missile Weapons". It goes in the vertical tube in the 1/3 aft area.
