A Coast Guard 25-foot defender class boat from Station Seattle enforces a security zone around a Washington State Ferry in Elliot Bay Dec. 22, 2003.
The United States Coast Guard plans to replace a mixture of older boats with up to 700 Defender class boats.
The boats are 25 feet in length, capable of 40 knots, powered by twin outboard motors.
They can be armed with pintle-mounted machine guns or grenade launchers.
The boats will serve a variety of missions, including search and rescue, port security and constabulary duties.
