Fast attack craft

A fast attack craft (FAC), sometimes referred to as a Patrol Torpedo Gunboat (PTG) or a Patrol Craft (PCG), is a small, fast, agile, offensive, often affordable warship armed with anti-ship missiles, gun or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. Their displacements are usually under 700 tons, and they can reach speeds of 25+ knots or 46+ kph. A FAC's main advantage over other warship types is its affordability. Many FACs can be deployed at a relatively low cost, allowing a navy which is at a disadvantage to effectively defend itself against a larger adversary. A small boat, when equipped with the same weapons as its larger counterpart, can pose a serious threat to even the largest of capital ships. Their major disadvantages are poor seagoing qualities, cramped quarters and poor defence against aerial threats.
