MetalCraft Marine Inc. (MCM) has won a $31m contract from the United States Coast Guard (USCG) for its Long-Range Interceptor (LRI) III program. This marks the second contract given to MCM for its 11 meter high speed patrol boat Interceptor. The LRI equipment must be reliable and durable to withstand extreme environmental conditions (up to sea condition 5) and can operate over 236 nautical miles on each mission.
The LRI II was the first design that successfully navigated the salvage bay at the stern of the Coast Guard flagship, the National Security Cutter (NSC), 418 feet at up to 12 knots. Each ship will have twin Cummins 6.7-litre diesel engines powering twin Kongsberg A29 waterjets to a speed of 40 knots. It will also have an advanced navigation system from Raymarine and FLIR, suspension Shockwave and Shox seats.
Furthermore, it will have a wired crew communications system from David Clark Co. The open cabin layout allows the crew to provide return fire via a 180 degree arc of fire on both port and starboard sides. The LRI also features a Safariland man-portable ballistic panel package that can protect a crew of five from a 200° field of fire.
The boat features an enclosed or open cabin layout, allowing open operation in good weather conditions or fully enclosed operation in inclement weather. Moreover, each port and starboard gunner has a 180 degree arc of fire. The boat is used for a variety of operations including drug interception, search and rescue, as well as the team transfer. MCM is currently building another contract for the USCG for onboard 7M interceptors in addition to the LRI.
The LRI has been manufactured in sizes ranging from 7 to 20 meters (23′ to 65′) and has found great success with other military and law enforcement forces throughout North America. All LRI equipment must be reliable and durable to withstand extreme environmental conditions as the boats routinely operate at planing speed in sea conditions 5 (13′-17′).
