es. 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. In size they are usually between 50–800 tonnes and can reach speeds of . A fast attack craft'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.


History


19th century

As early as the mid-19th century, the
Jeune École The ''Jeune École'' ("Young School") was a strategic naval concept developed during the 19th century. It advocated the use of small, heavily armed vessels to combat larger battleships, and the use of commerce raiders to cripple the trade of the r ...
's ''poussiere navale'' theory called for a great number of small, agile vessels to break up invading fleets of larger vessels. The idea was first put into action in the 1870s with the steam-powered torpedo boats, which were produced in large numbers by both the

. These new vessels proved especially susceptible to rough seas and to have limited utility in scouting due to their short endurance and low bridges. The potential threat was entirely extinguished with the introduction of the torpedo boat destroyer (TBD) in 1893, a larger vessel which evolved into the modern

. It could mount guns capable of destroying the torpedo boat before it was within range to use its own weapons.


20th century

The idea was revived shortly before World War I with the craft using new gasoline engines. Italy and Great Britain were at the forefront of this design, with the coastal motor boat (CMB) and the '' motobarca armata silurante'' (MAS) (Italian: "torpedo armed motorboat"). The outstanding achievement of the class was the sinking of the Austro-Hungarian battleship by ''MAS. 15'' on 10 June 1918. The equivalent achievement for the CMBs was a lesser success; during the

Post-World War II

After World War II, the use of this kind of craft steadily declined in the United States and Britain, despite the introduction of safer diesel engines to replace the highly flammable gasoline ones, although the

s" or "missile cutters". The first few missile boats were originally torpedo boats, with the torpedo tubes replaced by missile launchers. Again, small fast craft could attack and destroy a major warship. The idea was first tested by the Soviet Union which, in August 1957, produced the which mounted two P-15 Termit missiles on a hull with a top speed of around . Endurance was limited to at and the vessels had supplies for only five days at sea. 110 Komar-class vessels were produced, while over 400 examples were built of the following with a significant portion of the total being sold to pro-Soviet nations. The first combat use of missile boats was an attack by two Egyptian Soviet-built Komar-class boats on the Israeli destroyer ''Eilat'' on 20 October 1967, several months after the

. The two boats launched a total of four P-15 missiles, three of which struck the ''Eilat'' and sank her with the loss of 47 crew dead or missing and over 90 wounded. The Soviet FACs prompted a

response, which became more intense after the sinking of ''Eilat''. The Germans and French worked together to produce a new FAC, resulting in the class, first commissioned in 1968. Built on a hull with four MM-38 Exocet missiles, a 76 mm gun forward and 40 mm twin guns aft, these vessels have a top speed of . Built until 1974, a total of 68 Combattante IIs were launched. The design was immediately followed by the Combattante III, and a great many other shipyards produced their own versions of the Combattante, including the Israeli Sa'ar/''Reshef'' variants.
