Mk VI Patrol Boat
The Mk VI PB is the U.S. Navy’s next generation Patrol Boat. The Mk VI PB’s mission is to provide operational commanders a capability to patrol shallow littoral areas beyond sheltered harbors and bays and into less sheltered open water for the purpose of force protection of friendly and coalition forces and critical infrastructure. The 85-foot Mk VI PB is designed for optimal performance, fuel economy, and firepower. Systems are designed to reduce Total Ownership Cost (TOC), minimize manpower and improve reliability and maintainability. Powered by twin diesel engines and water jets, the Mk VI PB is capable of speeds in excess 30 knots at full load and a range in excess of 600 nautical miles. She has berthing accommodations, galley and head/shower facilities to allow for extended missions. Additionally, the boat can be outfitted with ballistic protection and armed with a variety of crew served and remotely operated weapons.
