Small unit riverine craft

Summary

The small unit riverine craft (SURC) is a rigid-hull, armed and armored patrol boat used by the U.S. Marines and U.S. Navy to maintain control of rivers and inland waterways. They are similar in size and purpose to the much older Patrol Boat, River vessels used during the Vietnam War.

U.S. Navy Riverine Squadron 2 patrols the waters above Haditha Dam, Anbar Province, Iraq, in a Small Unit Riverine Craft.

The boats are built by Raytheon Naval & Maritime Integrated Systems, with a contract to build up to 100 boats. Raytheon's contract partners are SAFE Boats International of Bremerton, Washington and Boat Master of Fort Myers, Florida.

History edit

The boats were first deployed to Iraq and were used there by the now deactivated U.S. Marine Corps' Small Craft Company, being later turned over to the United States Navy Riverine Squadrons - units of the Navy Expeditionary Combat Command (NECC) that used the boats to patrol strategic areas of Iraq.

On Sept. 25 2013, the United States transferred six SURC patrol boats to the Philippine Marine Corps to provide a platform for command and control, reconnaissance, logistic/resupply, medical evacuation, counter-drug operations, humanitarian assistance, peacekeeping and non-combatant evacuation operations & will be deployed to augment sea-based forces addressing terrorism and lawlessness.[2]

Design edit

According to the Navy, “The primary mission of the SURC is to provide tactical mobility and a limited weapons platform for the ground combat element of a Marine Air Ground Task Force in littoral and riverine environments.”[3] The boat's secondary mission includes “command and control, reconnaissance, logistic/resupply, medevac, counter-drug operations, humanitarian assistance, peacekeeping, and noncombatant evacuation operations.”[3]

The boat is transportable by C-130 Hercules aircraft and can be launched from its trailer at lakeside. It also has the capability to turn 180 degrees in less than three boat lengths and accelerate to 25 knots (46 km/h) in less than 15 seconds.

Occasionally, the boats would have been equipped with an overhead covering to provide shade for the troops on board. Although there are few images to be found to back this up.

Other characteristics edit

Hull Type: Aluminum with full length beaching plates
Collars: High strength solid cell foam collar provides stability, redundant buoyancy, and small-arms ballistic protection
Weight: 17,500 lb (7,900 kg) craft and trailer
