"Valiant" has a 25 mm machine cannon mounted on the bow and is capable of firing high-explosive projectiles at a rate of 180 rounds per minute. In addition, the vessel mounts two .50 caliber heavy machine guns. The 24-foot "Cutter Boat Large" (CBL) and the 23 foot "Over The Horizon" (OTH) are used to visit and board other vessels at sea. The special towing bitt on the fantail allows "Valiant" to tow vessels up to 10 times her size. Another feature of "Valiant" is her ability to carry a Coast Guard HH-65 Dolphin helicopter. The helicopter extends the ships surveillance range for law enforcement and reduces response time for search and rescue mission.
