[edit] Etymology

The missile's name was given by M. Guillot, then the technical director at Nord Aviation, after a French word for flying fish (Exocoetidae).^[1]

[edit] Description

The Exocet is built by MBDA, a European missile company. Development began in 1967 as a ship-launched missile named MM 38. The air-launched Exocet was developed in 1974 and entered service with the French Navy five years later.^[2]

The missile is designed to hit large warships. It is guided inertially in mid-flight, and turns on active radar late in its flight to find and hit its target. Its solid propellant engine gives the Exocet a maximum range of 180 kilometres (110 mi; 97 nmi) for the Block 3 version and 70 kilometres (43 mi; 38 nmi) for the previous ones. The submarine-launched version places the missile and a naval booster inside a launch capsule.

The Exocet has been manufactured in a number of versions, including:

• MM38 (surface-launched)
• AM39 (air-launched)
• SM39 (submarine-launched)
• MM40 (surface-launched)

The chief competitors to the Exocet are the U.S.-built Harpoon, the Chinese Yingji series and the Swedish built RBS15.

[edit] MM40 Block 3

The newest MM40 version (MM40 block 3) has an improved range of 180 kilometres (110 mi; 97 nmi) through the use of a turbofan engine, and includes four air-intakes to provide continuous airflow to the engine during high-G maneuvers.

The Block 3 missiles accept guidance system waypoint commands, which allow them to attack naval target from different angles, to strike land targets, giving them a marginal role as a cruise missile.^[3][4]

[edit] History

[edit] Falklands Conflict

In 1982, during the Falklands War, Exocets became noted worldwide when Argentine Navy Exocet-equipped Super Etendard warplanes sank the British Royal Navy destroyer HMS Sheffield on 4 May 1982, and the 15,000 ton merchant ship Atlantic Conveyor, were struck by two Exocet anti-ship missiles, on 25 May. An MM38 ship-to-ship Exocet transferred from the Argentinean Navy destroyer ARA Guerrico to a land-based truck ^[5] damaged HMS Glamorgan on June 12.

While the Argentineans claimed that an Exocet-armed Super Etendard attack on May 30 damaged the aircraft carrier HMS Invincible, this claim is unfounded, due to the continued air operations of Invincible with no signs of damage. During the conflict the Argentinian Government several times claimed incorrectly that it had damaged several ships, with multiple previous claims to have damaged or sunk the aircraft carriers HMS Invincible and HMS Hermes, the two most important British warships there, and shot down Sea Harriers, due to some combination of the natural confusion of battle and propaganda purposes.

The Exocet that struck the HMS Sheffield impacted on the second deck, 2.4 metres (7 ft 10 in) above the waterline and penetrated deeply into the Sheffield's control room,^[6] near to the forward engine room, cracking the hull open roughly 1.2 by 3 metres (3.9 ft × 9.8 ft). It appears that the warhead did not explode.^[7] Accounts suggest that the initial impact of the missile immediately destroyed the ship's onboard electricity generating systems and fractured the water main, preventing the anti-fire mechanisms from operating effectively, and thereby dooming the ship to be consumed by the raging fire. Although the loss of Sheffield was a major shock to the British, the missile used earned itself a curious kind of respect, and the word "Exocet" passed into British colloquial usage to denote, "a devastating attack". It is still occasionally heard, and as of 2007, remains widely understood. The crew of the Sheffield and members of the British Task Force were of the opinion that the missile had exploded, but the official report from the RN Board of Inquiry, now available (2007) on the Internet, states that from the evidence available the warhead did not explode. The damage caused was due to the large kinetic energy of the missile, and the unused missile fuel that ignited on impact.

The Exocet that struck the Glamorgan failed to explode, but the unburnt rocket fuel caused a significant fire. It is likely that the Glamorgan was saved from complete destruction by the prompt action of the officers and men at the helm. With less than a minute's warning that a missile was incoming, they ordered maximum revolutions and turned to present her stern to the missile. When the missile struck, the ship was heeled far over to port and instead of striking the side the missile hit the coaming and was deflected upwards. The dent caused by the impact was clearly visible when the Glamorgan was being refitted in late 1982.

In the years after the Falklands War it was revealed that the British government and intelligence agencies were extremely concerned by the perceived inadequacy of the Royal Navy's anti-missile defences against the Exocet and the missile’s potential to tip the naval war decisively in favour of the Argentine forces. In London, a nightmare scenario was being envisioned in which one or both of the UK force’s two aircraft carriers (HMS Invincible and HMS Hermes) would be destroyed or incapacitated by Exocet attacks, which would make recapturing the Falklands much more difficult. To contain the Exocet threat a major intelligence operation was initiated to prevent the Argentine Navy from acquiring more Exocets. The operation included British intelligence agents claiming to be arms dealers able to supply large numbers of Exocets to Argentina, diverting Argentina from pursuing sources which could genuinely supply a few missiles. France denied deliveries of recently-purchased Exocet AM39s to Peru - to avoid the possibility of their being passed on to Argentina.

[edit] Middle East

Iraq fired an estimated 200 air-launched Exocets against Iranian shipping during the Iran–Iraq War with varying levels of success. Tankers and other civilian shipping were often hit.

On May 17, 1987, the pilot of an Iraqi Mirage F-1 allegedly mistook the U.S. Navy Oliver Hazard Perry class frigate USS Stark for an Iranian tanker and fired two Exocets at the warship. The first penetrated the port-side hull. The second entered at almost the same point, and left a 3-by-4-metre (9.8 ft × 13 ft) gash then exploded in crew quarters. Thirty-seven sailors were killed and twenty-one were injured. Stark was heavily damaged, but saved by the crew and sent back for repairs. The errant pilot was reportedly executed for his error, and his explanations for the attack are not available. Later, Iraqi officials denied that the pilot had been executed and stated that he was still alive.^[8]

[edit] The Lokata

In the late 1970s a civilian in Falmouth, Cornwall, England independently re-invented part of the Exocet's navigation system in one of his own inventions, the "Lokata Watchman", a navigation system for small boats.

[edit] Former operators

 Belgium

Belgian Navy operated Exocets on its Wielingen class frigates. Those warships were all sold in 2008

 United Kingdom

Royal Navy operated Exocets until the last MM38 armed surface vessel was decommissioned in 2002.

 Georgia

In many cases, the nearly-obsolescent Exocet missiles have been replaced by more modern and updatable ship to ship missiles such as the American-made Harpoon Missile, perhap on newer warships, incl. those in the Royal Navy.
