MK VI Patrol Boats

The MK VI patrol boats are designed and built by American boat manufacturer, Safe Boats International (SBI) to serve as the next-generation patrol boats for the US Navy. The 85ft patrol boats will replace the ageing patrol boat fleet of Naval Expeditionary Combat Command (NECC) and will support the Coastal Riverine Force (CRF).

SBI was awarded an initial $36.5m contract for six MK VI Patrol Boats in May 2012. The US Navy signed a $34.5m firm-fixed-price agreement with SBI for four additional MK VI patrol boats in July 2014. The agreement includes options for two more boats, bringing the total value of the contract to $52.2m. The US Navy plans to acquire a total of 48 Mark VI Patrol Boats.

The U.S. Navy quietly updated its fleet last month, adding its first new patrol boat since the mid-1980s. The Mark VI Patrol Boat is an 85-foot vessel that seats 10 crewmen and eight passengers, reaching a sprint speed of more than 35 knots.

Built by Safe Boats International, a military supplier with the motto, “God, Country and Fast Boats,” the Mark VI is designed to patrol shallow littoral areas, support search-and-seizure operations, and function as a high value shipping escort, among other duties. The Navy expects to deploy its first 10 MK VI boats next year and expand the fleet starting in 2018. Source bloomberg.com

SBI received a contract modification in July 2015 to supply two additional boats to the US Navy, bringing the total number of orders to 12.

Excerpt

U.S. Navy surface warfare experts are ordering two 85-foot patrol boats that have surveillance and battle-management networking, as well as flat-screen monitors mounted throughout the vessels.

Officials of the Naval Sea Systems Command in Washington announced a $17.8 million contract modification Friday to Safe Boats International LLC in Bremerton, Wash., to provide two Mark VI patrol boats.

The boats are being built at SBI’s large craft production facility (LCPF) situated in the Port of Tacoma, Washington. SBI hired 100 new employees in addition to the existing 275 workers to build the boats.

The first of 12 MK VI patrol boats was delivered to the US Navy in August 2014. The boat successfully completed sea trials and was handed over to NECC for operational deployment in 2015. The remaining 11 boats are expected to be built by March 2018.

Coastal Riverine Group 2 (CRG 2) of the US Navy received two MK VI patrol boats in September 2015.

MK VI patrol boat missions

The MK VI patrol boat is the first mission-specific patrol boat designed for the US Navy since the mid-1980s. It will replace the smaller 68ft Mark V and 34ft Sea Ark to defend the green-water navy. The CRF will deploy the patrol boats for critical infrastructure protection (CIP) in and around foreign ports across the world.

U.S. Defense System

The boats can operate in brown, green or blue waters, and will be deployed to patrol shallow littoral regions beyond the harbours and bays. They can conduct missions in the open ocean for protecting defence forces.

The versatile patrol vessels can support search-and-seizure operations, maritime intercept operations, theatre security cooperation operations and other clandestine security force activities. They can function as escorts for high value assets and also take part in mine hunting and fast attack combats.

The boat is ideal for coordinated efforts with Naval Special Warfare and Naval Special Operations operators such as Navy SEALs and Explosive Ordinance Disposal (EOD).

Unmanned systems

The U.S. Navy’s MK VI Patrol Boat is designed to carry a variety of unmanned systems.  At Sea Air Space 15, the boat displayed a PUMA UAV. It will also be configured to carry two MK 18 Mod 2 Kingfish mine hunting UUVs.  Source navaldrones.com

by gaston18

MK VI patrol boat is a modification of the 780 Archangel Class patrol boat, which was also built by SBI. The boat is designed to decrease Total Ownership Cost (TOC) and manpower. Its aluminium hull is enhanced for performance, fuel efficiency, easy maintenance and firepower.

The boat is equipped with ballistic protection, with armour plating around the engines and fuel storage. The boats are small enough to fit inside the well deck of LHD, LPD and LSD class amphibious warfare ships. Thus, they can be transported to any location in a short period of time.

Weaponry

The patrol boat is armed with two remotely controlled and stabilised MK-38 Mod2 25mm machine gun systems, small arms mounts and six crew served 50-calibre machine guns. It also has the provision to install other weapons such as mini guns, grenade launchers and smaller calibre machine guns.

The MK 38 MOD 0 25mm MGS replaced the MK 16 20mm gun system and was then later upgraded to a MK 38 MOD 1 MGS. A total of 387 MK 38 MOD 1 MGSs were procured and deployed in the U.S. Navy and U.S. Coast Guard (USCG). In 2003, the chief of Naval Operations (CNO) directed the Navy to pursue a simple, stabilized, low cost solution for outfitting near-term deployers to counter small boat threats. The Navy began fielding the Mk 38 MOD 2 in 2005. Due to the success of the MK 38 MOD 2 MGS, the program scope was expanded in July 2012 to add several ship classes and to develop a modification to the system. This modification is known as the MK 38 MOD 3 which is a technical refresh of the MK 38 MOD 2. The first MK 38 MOD 3 is to be fielded in FY17.  Source navy.mil
