Congreve rocketThe Congreve rocket was a type of rocket artillery designed by British inventor Sir William Congreve in 1808. The design was based upon the rockets deployed by the Kingdom of Mysore against the East India Company during the Second, Third, and Fourth Anglo-Mysore Wars. Lieutenant general Thomas Desaguliers, colonel commandant of the Royal Artillery at Woolwich, was impressed by reports of their effectiveness, and undertook several unsuccessful experiments to produce his own rocket weapons.
Katyusha rocket launcherThe Katyusha (Катю́ша) is a type of rocket artillery first built and fielded by the Soviet Union in World War II. Multiple rocket launchers such as these deliver explosives to a target area more intensively than conventional artillery, but with lower accuracy and requiring a longer time to reload. They are fragile compared to artillery guns, but are cheap, easy to produce, and usable on almost any chassis. The Katyushas of World War II, the first self-propelled artillery mass-produced by the Soviet Union, were usually mounted on ordinary trucks.
Precision-guided munitionA precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
Rocket (weapon)In military terminology, a rocket is a self-propelled, generally unguided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even (in a few cases) as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System.
Multiple rocket launcherA multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple launchers which are fixed to a single platform, and shoots its rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads.
Mattress (rocket)Mattress was the term applied to ground-based British-devised multiple rocket launchers during World War II. Compared with the German and Soviet counterparts (the Nebelwerfer and Katyusha launchers respectively), the western Allies deployed these weapons late in the war. Nevertheless, they did see useful service as artillery support during the crossings of the Rhine and the Scheldt rivers. The first multiple rocket launch system developed by the British was designed to be deployed on warships and landing craft and fired in support of troops in a landing action.
Counter-battery fireCounter-battery fire (sometimes called counter-fire) is a battlefield tactic employed to defeat the enemy's indirect fire elements (multiple rocket launchers, artillery and mortars), including their target acquisition, as well as their command and control components. Counter-battery arrangements and responsibilities vary between nations but involve target acquisition, planning and control, and counter-fire. Counter-battery fire rose to prominence in World War I. Counter-battery radar detects incoming indirect fire and calculates its point of origin.
Artillery batteryIn military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships.
Fragmentation (weaponry)Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, or autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler. The correct term for these pieces is "fragmentation"; "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.
Indirect fireIndirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles. Indirect fire is most commonly used by field artillery and mortars (although field artillery was originally and until after World War I a direct fire weapon, hence the bullet-shields fitted to the carriages of guns such as the famous M1897 75 mm).
