Naval gunfire


Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term Naval Fires. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since the early days of naval warfare.

NGFS is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire.

When on the , ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines due to a predictable and steady (non-evasive) course.

An early use of shore bombardment was during the Siege of Calais in 1347 when Edward III of England deployed ships carrying bombardes and other artillery.

An early type of vessel designed for the purpose of shore bombardment was the bomb vessel, which came into use during the 17th century. These were small ships whose main armament was one or two large mortars, that fired explosive shells at a high angle. They were typically poor sailing craft that were of limited use outside their specialized role. However, small vessels armed with large mortars saw use as late as the American Civil War, when the Union Navy used them in several attacks on coastal fortifications.
