Naval Special Warfare Command has taken control of 12 of 13 Patrol Coastal
Cyclone Class Ships. The PC class has a primary mission of coastal 
patrol and interdiction, with a secondary mission of Naval Special 
Warfare support. Primary employment missions will include 
forward presence, monitoring and detection operations, 
escort operations, non-combatant evacuation, and foreign internal 
defense. The PC class operates in low intensity environments. 
Naval Special Warfare operational missions will include long range 
SEAL insertion/extractions, tactical swimmer operations, 
intelligence collection, operational deception, 
and coastal/riverine support. PCs will normally operate as a 
two boat detachment. This allows enhanced support and facilitates 
the assignment of one Mobile Support Team, MST, every two ships.

The newest craft in the Naval Special Warfare inventory
is the MK V SOC. It's primary mission is a medium 
range insertion and extraction platform for Special 
Operations Forces in a low to medium threat environment. 
The secondary mission is limited Coastal Patrol and 
Interdiction, specifically limited duration patrol and 
low to medium threat coastal interdiction. The MK V SOC 
will normally operate in a two craft detachment with a 
Mobile Support Team.

The Mobile Support Team provides technical assistance and 
maintenance support during mission turnaround. The MK V SOC 
is fundamentally a single sortie system with a 24 hour 
turn- around time. The typical MK V SOC mission duration is 
12 hours. The MK V SOC is fully interoperable with the PC ships 
and NSW RIBs. As such, all could be employed from a Forward 
Operating Base, in a synergistic effect. A MK V SOC detachment, 
consisting of two craft  and support equipment, will be 
deployable on two USAF C-5 aircraft into the gaining theater 
within 48 hours of notification. A detachment is transportable 
over land on existing roadways. Detachments are not configured 
nor manned to provide their own security, messing, or berthing

The SOC-R, is designed for high speed 
riverine patrol operations in contested areas of 
operations, and insertion/extraction of SEAL Team 
elements. More than 500 units were built when first 
introduced in the Vietnam conflict in 1966 although 
the current inventory is 24 craft. They can be 
transported in C-5 aircraft on skids. The PBR is 
heavily armed and vital crew  areas are protected 
with ceramic armor. The weapons loadout on this 
craft includes both single  and twin .50 caliber 
machine gun mounts, 40 mm grenade launchers and 
small arms. The hull is  reinforced fiberglass 
with two Jacuzzi type waterjet pumps for propulsion. 
The unit can operate in shallow debris filled water. 
The craft is highly maneuverable and can turn 
180 degrees and reverse course within the distance 
of its own length while operating at full power. 
Engine noise silencing techniques have been 
incorporated into the design and improved over the 
years. The combination of relatively quiet operation 
and its surface search radar system make this unit an   
excellent all-weather picket as well as a shallow water 
patrol and interdiction craft.

The Mini-Armored Troop Carrier is a 36 foot 
all-aluminum hull craft designed for high-speed patrol, 
interdiction, and combat assault missions in rivers, 
harbors, and protected coastal areas. The MATC has a 
large well area for transporting combat equipped troops, 
carrying cargo, or for gunnery personnel operating the 
seven organic weapon stations. The MATC  propulsion 
system is similar to that of the PBR, with an internal 
jet pump, which moves the water on the same principle 
as the air breathing jet engine. This type of 
propulsion is especially  appropriate for beaching 
operations. A hydraulic bow ramp is designed to aid 
the insertion and  extraction of troops and equipment. 
The craft has a low silhouette which makes it difficult 
to detect in all speed ranges. The unit is extremely 
quiet, particularly at idle speeds. A high  resolution 
radar and multiple communications suite, provides a 
good all weather surveillance and  command and control 
presence for interdiction and anti-smuggling operations. 
The overhead  canopy can be removed or stowed below. 
Crew size is normally four but can be modified  
depending on the mission and mission duration.

The Light Patrol Boat is a lightly armed 
Boston Whaler type craft with no armor. 
This craft is constructed of fiberglass 
with reinforced transom and weapons mount 
areas. It is powered by dual outboard motors 
and is highly maneuverable. It is useful in 
interdicting a lightly armed adversary but 
should not be used to engage a heavily armed 
or well organized enemy. It functions 
effectively in policing actions, harbor control, 
diving and surveillance operations, 
riverine warfare, drug interdiction, 
and other offensive or defensive purposes.

The weapon mountings can include .50 caliber 
heavy machine guns or 7.62mm machine guns 
mounted on 180-degree mounts, providing an 
effective weapon employment in any direction. 
Due to its unique hull design, the PBL is 
excellent for the riverine environment, 
allowing it to operate in virtually any water 
depth. Its two low-profile engines are capable 
of providing eight hours of continuous operation 
at a fast cruise speed of 25-plus knots. 
It displaces 6,500 lb. fully loaded and is 
transportable via its own trailer, helicopter 
sling, or C-130 aircraft. Normal crew size is 
three personnel.

The SEAL Delivery Vehicle  MK VIII is a "wet" 
submersible, designed to carry combat swimmers 
and their cargo in fully flooded compartments. 
Submerged, operators and passengers  are sustained 
by the individually worn underwater breathing apparatus. 
Operational  scenarios for the vehicle include underwater 
mapping and terrain exploration, location and recovery of 
lost or downed objects, reconnaissance missions, and 
limited direct action missions. 

The vehicle is propelled by an all-electric propulsion 
subsystem powered by re-chargeable silver-zinc batteries. 
Buoyancy and pitch attitude are controlled by a ballast 
and trim system; control in  both the horizontal and 
vertical planes is provided through a manual control 
stick to the rudder, elevator, and bow planes. 
A computerized Doppler navigation sonar displays speed,
distance,  heading, altitude, and other piloting functions. 
Instruments and other electronics units are housed in dry, 
watertight canisters. The special modular construction 
provides easy removal for  maintenance. Major subsystems 
are Hull, Propulsion, Ballast/Trim, Control, 
Auxiliary Life  Support, Navigation, Communications 
and Docking Sonar.




The Dry Deck Shelter allows for the launch and recovery 
of an SDV or combat rubber raiding craft (CRRC) with 
personnel from a submerged submarine. It consists of 
three modules constructed as one integral unit. 
The first module is a hangar in which an SDV or CRRC 
is stowed. The second module is a transfer trunk to 
allow passage between the modules and the submarine. 
The third module is a hyperbaric recompression chamber. 
The DDS provides a dry working environment for mission 
preparations. In a typical operation the DDS hangar 
module will be flooded, pressurized to the surrounding 
sea pressure, and a large door is opened to allow for 
launch and recovery of the vehicle. A DDS can be 
transported by USAF C-5/C-17 aircraft, rail, highway, 
or sealift. The DDS is 40 feet long and weighs 65,000 lb.
