Patrol boat

 

The classification of a patrol boat is often subjective, but they are generally small naval vessels that are used to patrol national waters or a certain jurisdiction. They may be as large as a corvette or even a frigate, though the term may also be used for vessels as small as a yacht or rigid inflatable boat. They can include fast attack craft, torpedo boats, and missile boats. They may be broadly classified as inshore patrol vessels (IPVs) or offshore patrol vessels (OPVs). OPVs and medium size cutters are usually the smallest ship in a navy's fleet that are large and seaworthy enough to patrol off-shore in the open ocean, while IPVs are typically too small to do so and are instead kept in lakes or rivers, or close to coasts; IPVs specifically used in rivers can also be called "riverine patrol vessels". Large patrol vessels, Heavy patrol vessels and Large cutters are the largest type of patrol ships and are typically more than 100 m (330 ft) in length.

Seagoing patrol boats are typically around 30 m (100 ft) in length and usually carry a single medium caliber artillery gun as main armament, and a variety of lighter secondary armament such as machine guns, while others include the sophisticated close-in weapon system. Depending on their role, vessels in this class may also have more sophisticated sensors and fire control systems that would enable them to carry torpedoes, anti-ship missiles, and surface-to-air missiles.^[1]

 

During both World Wars, in order to rapidly build up numbers, all sides created auxiliary patrol boats by arming motorboats and seagoing fishing trawlers with machine guns and obsolete naval weapons. Some modern patrol vessels are still based on fishing and leisure boats.

The United States Navy operated the Pegasus class of armed hydrofoils for years in a patrol boat role. During the Vietnam War, the U.S. Navy ordered 193 aluminum hulled Patrol Craft, Fast (PCFs),^[2] also known as Swiftboats, for brown water naval operations. The Patrol Boat, River (PBR, sometimes called "Riverine" and "Pibber") was a fiberglass hulled vessel also designed and used for inland river operations during the Vietnam War, and became an icon of water operations during the war due to its use in the 1979 film Apocalypse Now.

Most modern designs are powered by gas turbine arrangements such as CODAG, and speeds are generally in the 25–30 knots (46–56 km/h; 29–35 mph) range. The largest OPVs might also have a flight deck and helicopter embarked. In times of crisis or war, these vessels are expected to support the larger vessels in a navy, though some smaller navies are mostly composed of just patrol boats.
