The Multi-role Intermediate Support Craft, made by Stidd Systems Inc., of Greenport, N.Y., is a submersible boat that can travel at speeds up to 30 knots on the surface. “This is breakthrough technology,” said the firm’s government affairs director, David J. Wilberding. “There’s nothing like it on the planet.”
The craft carries a crew of two, plus nine passengers or 3,500 pounds of cargo. It can be outfitted with a .50 caliber machine gun, MK-19 40 mm grenade launcher and other weapons systems.
