The Navy’s New Patrol Boat


The Navy has placed orders for five Patrol Boats of a new type, with up to 48 planned. Announcements here and here. At 85 ft long, it is a size the Coast Guard is familiar with, and it is made by Safe Boats International LLC, a company the Coast Guard contracted to build its own Response Boat-Small, Special Purpose Craft-Law Enforcement (SPC-LE), and Special Purpose Craft-Near Shore Life Boat (SPC-NLB). In fact the new patrol boat is a development of the same family as the Special Purpose Craft-Near Shore Life Boat (SPC-NLB) which suggest it may even be self-righting.

Step-down cut-outs on the hull, similar to those on 47 foot motor lifeboats, are visible in the illustration, making it easier to board smaller vessels or pull people from the water. Sprint speed is up to 41 knots with 35 sustained. Accommodations appear crowded and relatively austere compared to Coast Guard patrol boats.

Interestingly the boats are being bought through GSA. At approximately $6M the price is not bad.

The Center for International Maritime Security has some interesting discussion about how they might be used. Below is an illustration from that post, originally provided by Navy Undersecretary Bob Work at a CATO Institute event,  showing how the boats might be transported in the well decks of various classes of amphibious warfare ships.

Mk VI Well Deck

Lee Wahler, who writes for and is a frequent contributor here, believes the boat grew out of this Request For Information, from 12 Nov 09. (Thanks Lee) This may provide some additional insight into the rationale behind the design:


This synopsis is issued in anticipation of a potential future procurement program. The Naval Sea Systems Command is conducting market research to determine the existence of a Force Protection – Coastal Craft type boat possessing the characteristics below. GENERAL MISSION: The Force Protection – Coastal (FP-C) Craft requires a tactically sized, highly reliable, combatant craft capable of operating from land or maritime platforms. The mission of FP-C will be to provide a capability to persistently patrol shallow littoral areas beyond sheltered harbors and bays, and into less sheltered open water out to the Departure Sea Area (DSA) for the purpose of force protection of friendly and coalition forces and critical infrastructure. Mission profiles include patrol of Maritime Pre-Positioning Forces (MPF) and Joint Logistics Over The Shore (JLOTS) anchorage and marshaling areas, High-Value Asset (HVA) shipping escort, and tactical surface mobility for Visit, Board, Search, and Seizure (VBSS) operations, Critical Infrastructure Protection (CIP), Maritime Interdiction Operations (MIO) overwatch, Theater Security Cooperation (TSC), and Security Force Assistance (SFA). CRAFT REQUIREMENTS: General Note: All requirements (unless designated “desired”) are the minimum acceptable operational value. Desired requirements are capabilities that would optimize craft performance and are beyond which any gain in utility does not warrant additional expenditure. Craft employment will be Day / Night, in all weather with a minimum of 24 hour endurance with a given notional mission profile. Craft will conduct sustained continuous operations in 10 feet (Very Shallow Water (VSW) curve) depths and greater at all craft speeds. Craft to be fully capable conducting mission in NATO Sea State 3. Craft will operate versus a level II threat, including: small tactical, waterborne units, and unconventional warfare units armed with small arms, rocket propelled grenades, and machineguns, improvised explosive devices and mines. Craft will operate from a sea or expeditionary shore base, or dock ship. Mission Capabilities: Vessel Operations: with self-fendering the craft is to be capable of conducting boarding operations on vessels up to 50 tons and shoulder 25 ton vessels without incurring significant damage to the fender or the craft.

    • This is a snip-it from the article.

      “In that same talk, Navy Rear Admiral Paul Schlise, the director of the Office of the Chief of Naval Operations’ Surface Warfare division, did confirm that the service is planning to supplant its Cyclone class patrol craft, which are larger than the Mk VIs, with a combination of Littoral Combat Ships (LCS) and U.S. Coast Guard patrol boats.”

      That sure sounds like the CG will be involved to me.
