Mark V Special Operations

Function: The Mark V is used to carry Special Operations Forces (SOF), primarily SEAL combat swimmers, into and out of operations where the threat to these forces is considered to be low to medium. They also support limited coastal patrol and interruption of enemy activities.

Description: The MARK V Special Operations Craft (SOC) is the newest, versatile, high performance combatant craft introduced into the Naval Special Warfare (NSW) Special Boat Squadron (SBR) inventory to improve maritime special operations capabilities. MARK Vs are organized into detachments comprised of two boats, crews and a deployment support package mounted on cargo transporters. The detachment can be delivered in-theater rapidly by two C-5 aircraft, by a well or flight deck equipped surface ships and, if appropriate, under their own power. The detachment can be deployable within 48 hours of notification and ready for operations within 24 hours of arrival at a forward operating base. They can operate from shore facilities, from well-deck equipped ships or from ships with appropriate crane and deck space capabilities. The MARK Vs are a result of a streamlined acquisition effort managed by the United States Special Operations Command (USSOCOM) Special Operations Acquisition Executive (SOAE). From the awarding of the contract to actual possession of the first boat took only 18 months .

T-AGS Survey Ships

Function: Military Sealift Command's Special Missions program supports worldwide oceanographic programs with ships which perform acoustical, biological, physical and geophysical surveys. Ships such as USNS Silas Bent (TAGS 26), USNS Kane (TAGS 27) and USNS Bowditch (TAGS 62) gather data which provides much of the military's information on the ocean environment. Oceanographic and hydrographic survey ships are used to study the world's oceans. The collected data helps to improve technology in undersea warfare and enemy ship detection. The oceanographic and hydrographic survey ships' multibeam, wide-angle precision sonar systems make it possible to continuously chart a broad strip of ocean floor. Two oceanographic ships survey the sea bottom and collect hydrographic data, charting three-fourths of the world's coastlines. USNS John McDonnell (TAGS 51) and USNS Littlehales (TAGS 52) make it easier for navigators to find their way along well-traveled and not-so-familiar shipping routes.

History: The USNS John McDonnell (TAGS 51) was laid down Aug. 3, 1989, and the USNS Littlehales (TAGS 52) on Oct. 25, 1989. The McDonnell launched Aug. 15, 1980, the Littlehales on Feb. 14, 1991. The contract for the Pathfinder class of surveying ships was awarded in January 1991 for two ships with an option for a third which was taken up May 29, 1992. A fourth ship was ordered in Oct. 1994 with an option for two more. A fifth ship was ordered Jan. 15, 1997.

Description: The Silas Bent class of surveying ships were designed specifically for surveying operations. They have a bow propulsion unit for precise maneuverability and station keeping. The John McDonnell class of survey ships carries 34-foot survey launches for data collection in coastal regions with depths between 10 and 600 m and in deep water to 4,000 m. A small diesel is used for propulsion at towing speeds of up to 6 knots. SIMRAD high-frequency active hull-mounted and side scan sonars are carried.

SSN637 - Sturgeon Class F

Function: America's front-line fast attack nuclear submarine during the '60s and '70s.

History: Following in the steps of the Skipjack and Permit class nuclear submarines, the Sturgeon class incorporated a a new hull design and sensor package. Larger than either of the two earlier designs while using the same reactor plant, the Sturgeon sacrificed speed for increased weapons payload and crew efficiency. Beginning with the Archerfish (SSN678) the hull was lengthened an additional 10 feet. In addition to their regular duties as anti submarine platforms, the Sturgeon class submarines were also tasked with coastal reconnaissance and electronic intelligence gathering. Furthermore, between 1982 and 1991 six 637 class boats (SSN 678-680, 682, 684, and 686) were modified to carry the SEAL Dry Deck Shelter (DDS.) The DDS is a submersible air lock and storage area allowing for the transporting, delivery and recovery of SEAL teams and all their associated equipment. The Sturgeon class submarines were slowly phased out of front line service by the faster, more capable Los Angeles class submarines during the 80's and 90's though those still in service continue to perform intelligence gathering and support special operations missions.

SSN640 - Benjamin Frankli

Function: Benjamin Franklin class Fleet Ballistic Missile Submarine converted for special operations support.

History: Commissioned on December 10, 1965 as the second of the Benjamin Franklin class Fleet Ballistic Missile Submarines (SSBN) the USS Kamehameha served as an SSBN through 1992, conducting a total of 63 deterrent patrols. Following her withdrawl from the SSBN fleet, Kamehameha was extensivly modified to support Navy special operations missions. To create additional living space the entire ballistic missile section was removed and turned into living quarters where embarked special operations personnel could rest, train, plan operations, and maintain their equipment in relative comfort (especially when compared to the cramped quarters associated with the much smaller Sturgeon and Los Angeles class Fast Attack Submarines.) In addition, Kamehameha was modified to accommodate two Dry Deck Shelters (DDS) as well as 2 SEAL Delivery Vehicles. With the decommissioning of her sister ship, the USS James K Polk (SSN645) in 1999, the Kamehameha remains the only converted SSBN in active service.

SSGN - Guided Missile Sub

Function: SSGN Guided Missile Submarines are nuclear-powered submarines armed with tactical missiles and the ability to transport and support special operations forces.

Entered Navy: Beginning 2003 / 2004.

Description: Four Ohio-class Trident submarines that were previously scheduled for inactivation during Fiscal Years 2003 and 2004 are being converted to guided missile submarines (SSGN) over a five-year period ending in 2008. The primary missions of the SSGN will be land attack and Special Operations Forces (SOF) insertion and support. Secondary missions will be the traditional attack submarine missions of intelligence, surveillance and reconnaissance (ISR), battle space preparation, and sea control.

These ships will be armed with up to 154 Tomahawk? or Tactical Tomahawk? land attack missiles. They will have the ability to carry and support a team of 66 SOF personnel for up to 90 days as compared to 15 days for a SOF outfitted fast attack submarine (SSN). Clandestine insertion and retrieval of these Special Operations Forces will be enhanced by the ability to host dual dry deck shelters and/or Advanced Seal Delivery System. Each SSGN will be able to conduct a variety of peace-time, conventional deterrent, and combat operations all within the same deployment.

USS Ohio (SSBN 726) entered the conversion yard on 15 November 2002. On 14 January 2003, USS Florida (SSBN 728) became the first Ohio-class submarine to launcha cruise missile. The launch was made from underwater in the Gulf of Mexico.
