The Exocet is built by MBDA, a European missile company. Development began in 1967 by Nord as a ship-launched missile named MM 38. A few years later Aerospatiale and Nord merged. The basic missile body design was based on the Nord AS30 air to ground tactical missile. The air-launched Exocet was developed in 1974 and entered service with the French Navy five years later. The relatively compact missile is designed for attacking small- to medium-size warships (e.g. frigates, corvettes, and destroyers), although multiple hits are effective against larger vessels, such as aircraft carriers.It is guided inertially in mid-flight and turns on active radar late in its flight to find and hit its target. As a counter measure against the air defence around the target, it maintains a very low altitude during ingress, staying 1–2 m above the sea surface. Due to the effect of the radar horizon, this means that the target may not detect an incoming attack until the missile is only 6000 m from impact. This leaves little time for reaction and stimulated the design of CIWS.

 2. Harpoon
Name                    Harpoon
Caption                 A Harpoon missile on display at the USS Bowfin museum at Pearl Harbor, Hawaii.
Origin                     United States
Type                        Anti-ship missile
Manufacturer         McDonnell Douglas Boeing Defense, Space & Security
Unit cost                US$1,200,000 for Harpoon Block II
Service                  1977–present
Engine                   Teledyne Turbojet/solid propellant booster for surface and submarine launch; greater than 600 pounds (greater than 272.2 kg) of thrust
Weight                  with booster
Length                   Air launched: ; Surface and submarine launched:
Speed                    (240 m/s)
Vehicle range          in excess of depending on launch platform
Altitude                  Sea-skimming
Guidance                Sea-skimming cruise monitored by radar altimeter / active radar terminal homing
Launch platform               multi-platform:

The Harpoon is an all-weather, over-the-horizon, anti-ship missile system, developed and manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). In 2004, Boeing delivered the 7,000th Harpoon unit since the weapon's introduction in 1977. The missile system has also been further developed into a land-strike weapon, the Standoff Land Attack Missile (SLAM).
The regular Harpoon uses active radar homing, and a low-level, sea-skimming cruise trajectory to improve survivability and lethality. The missile's launch platforms include:

·  Fixed-wing aircraft (the AGM-84, without the solid-fuel rocket booster)
·  Surface ships (the RGM-84, fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's main turbojet to maintain flight)
·  Submarine  (the UGM-84, fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube);
·  Coastal defense batteries, from which it would be fired with a solid-fuel rocket booster.

The missile is comparable to the French-made Exocet missile, the Swedish RBS-15 missile, the Russian SS-N-25 Switchblade, the British Sea Eagle missile, and the Chinese Yingji.

 3. Otomat
Type                       Medium-range anti-ship missile
Service history
In service             1977
Production history
Manufacturer    MBDA
Weight                  770 kg with booster
Length                   4.46 m
Diameter              0.4 m
Warhead              210 kg
mechanism         Impact and proximity
Engine                   Turbojet engine
range                     180+ km
Speed                    310 m/s
system                  Inertial, GPS and active radar
platform               Surface-launched

The Otomat missile program started in 1967, the same year in which the Israeli destroyer Eilat was sunk by three Soviet-made P-15 Termit anti-ship missiles. This event raised awareness about the effectiveness of such weapons and prompted the development of similar systems in Western countries, such as the Harpoon in the United States. However, it is unknown whether the Otomat program started before or after the Eilat event.
The Otomat program was undertaken by the Italian Oto Melara Corporation in cooperation with the French Matra Corporation. The aim was to develop an anti-ship missile powered by a turbofan which would allow more range and a heavier warhead than rocket-powered missiles then being developed in Europe such as the French Exocet and the German Kormoran. Trials started in 1971 and development of the Mk1 version of the Otomat officially ended in 1974.

The history of the missile can be traced back to the Swedish missile RB 08 from the mid-1960s (which in turn had been developed from the French CT-20 target drone). The RB 08 was an anti-ship missile, which functioned basically in the same way as the RBS-15. Both missiles are guided by an autopilot mid-course guidance and a monopulse J-band radar. The sustainer engine is a small turbojet.
