The History and development of the Corsair RS1 and Constellation RS2 Manned Diesel Electric Submarines.

	Autonomous manned submarines began their practical development over 100 years ago. By the turn of the century they were providing naval organizations with reliable and safe platforms for a host of submerged operations...
	For decades specialized naval submarines utilizing diesel and nuclear engines have performed intervention, Mapping and Inspection missions with a degree of effectiveness that rivaled any surface deployed platform available.
	These submarines operate without the need of surface deployment support ships, reducing weather sensitivity, project delays and cost.
	The RS Submarine's pressure hull is formed out of high tensile strength steel, similar to that which is used in our naval submarine fleet. Proven, German made diesel engines matted to reliable battery systems delivers a level of autonomy previously restricted to the Navy.
	The RS Submarine is engineered large enough to comfortably accommodate up to six personnel, yet small enough to be economically transported by road, rail or ship.
	Today, with over 12 years of offshore experience, the RS Diesel Electric Submarine is available for worldwide charter to marine research centers, commercial offshore industries and qualified naval forces located in the United States and abroad.
