US Navy SPWS
Surface Planing Wet Submersible
Naval Special Warfare forces are frequently called on to perform missions from platforms that are OTH (over the horizon) from their targets. In the past this has meant a long ride in either a slow submarine or a vulnerable small boat. The new Surface Planing Wet Submersible seeks to give them the ability to rapidly approach a target and yet infiltrate invisibly so that the SEALs or EOD forces can retain the element of surprise. The SPWS is a vehicle designed to operate both as a submersible and as a high-speed boat. Currently being tested, the SPWS design criteria called out for the ability to carry a six-man team and 1,830 pounds of gear up to 165 nautical miles away on the surface or 18 NM under the surface. Surface speed is to be around 30 Kts and submerged speeds are thought to be around 6 Kts. The SPWS is powered by a diesel engine on the surface and batteries underwater, with the diesel recharging the batteries during surface running. Operating depth will be around 65 feet and the two crew members will have a sonar navigation system. The SPWS is transportable by Air Force cargo aircraft such as the C-5, C-17, and C-130 and can also be carried under helictopers such as the MH-53J/M Pave Low. Most of the details of the SPWS are still classified, but it is known that STIDD Systems of Greenport, NY, was awarded a nearly $4 million contract in the FY2002. LINKS:COMMERCE BUSINESS DAILY ISSUE OF OCTOBER 30, 2000 PSA #2716 SOLICITATIONS Notice Date: October 26, 2000 Description The United States Special Operations Command (USSOCOM) Special Operations Acquisition and Logistics Center, Directorate of Procurement intends to negotiate on a sole source basis with Stidd Systems of Greenport, NY in accordance with 10 U.S.C. 2304c (1) and FAR 6.302-1; Only one responsible source and no other supplies or service will satisfy the agency needs for a Surface Planing Wet Submersible (SPWS), also known as a reversible submersible boat or hybrid Seal Delivery Vehicle. The Navy exclusively licensed this technology to STIDD Systems for further development, at STIDD's own expense. STIDD has continued to develop this technology at their own expense and holds several patents for this technology. The Navy's Special Warfare Forces, NSW, have the need for innovative mobility technologies that can rapidly transport personnel, sensors, and payloads from over the horizon (OTH) to a near shore area of operation (AO). Moreover, once they are in the AO they must remain undetected. USSOCOM intends to continue to assess the feasibility of utilizing the SPWS technology. Therefore, USSOCOM proposes to enter sole source negotiations with STIDD Systems Inc. The specific government goals are the following: Surface Range 165 NM @ 30 knots cruise Subsurface Range 18NM @ 6 knots Personnel Capacity 2 crew, 4 pax Personnel/Cargo Capacity 1830 lb. Surface Propulsion Fuel Diesel Subsurface Navigation to include a Sonar Operating Depth 66FSW External Air Transport Capable The craft shall meet the requirements of MIL-STD-1791 for transportability on C-130, C-141, C-5, and C-17 aircraft. The craft on its trailer shall comply with all Department of Transportation and U.S. Federal Motor Safety Standards and not require special permits for over-the-road transit. Compatible to carry two SEAL Transport Devices, STD. The government anticipates the resultant contract will be a multi phased action with incrementally funded option CLINS reflecting the design and fabrication of the boat with surface propulsion capability in Phase I and subsurface propulsion subsystems in Phase II. |
