Anti-ship Missiles OTO-Melara/Matra Otomat (continued) Specification Otomat Dimensions: length 4.82 m (15 ft 9.75 in) diameter 46.0 cm (1 ft 6.1 in) span 1.19 m (3 ft 10.85 in) Weights: total round 698770 kg(l lb) warhead 210 kg (463 lb) Performance: maximum speed Mach 0.9 range 60 km (37.3 miles) as a single missile or 80 km (50 miles) when fired in salvo The Otomat is found in both coastal defence and shipborne versions. MM- ISRAEL S 3 IAI Gabriel Developed in the mid-1960s as the main armament for the 'Saar' class of missile craft the Israel Aircraft Indus­tries Gabriel has been proved to be one of the most successful anti-ship missiles ever used in combat. During the 1973 'Yom Kippur' war it was re­sponsible for sinking a large number of Arab warships and neutral merchant­men. The missile is carried in a rein­forced glassfibre container-launcher that can be mounted either in fixed single orin trainable triple cell units. Before launch the missile's guidance system is programmed with target data obtained from the launch plat­form's own sensors. The missile is then fired and under control of its twin gyro system and radio altimeter (working on the cruciform rear fins) assumes a cruise flight profile to the target area. The initial part of this trajectory is flown at around 100 m (330 ft) with a prog­rammed descent to 20 m (66 ft) for the major part. At a range of 1-2 km (1,095-2190 yards) from the estimated target position the missile switches on its seeker acquires the target and de­scends to one of the three pre-set ter­minal attack heights of between 1 and 3 m (3 and 10 ft) for the attack the actual height being dependent on the sea state encountered. In the case of the Gabriel Mk I and Gabriel Mk II, terminal homing is carried out by a semi-active radar seeker that relies on target illumination by the I-band target designator radar of the launch plat­form although a manual/optical control system and a command guidance with radar tracking mode are also avail­able. In the Gabriel Mk III homing is by an I-band frequency-agile active radar system which allows a fire-and-forget mode to be employed the other two guidance options are also available for use. The Gabriel shipboard system is designed to permit the use of all three inversions a single ship the different The Gabrielis available in three marks for shipboard use by Israel. characteristics of each type allowing maximum inflexibility mission plan­ning. The surface-launched Gabriel Mk I and Mk III are operated only by Israel while the Gabriel Mk II is also used by Chile Kenya Singapore, South Africa Taiwan and Thailand In the early 1980s the Gabriel Mk III was developed into two air-launched variants for use by the Israeli air force on its McDonnell Douglas Phantom, McDonnell Douglas Skyhawk IAI Kfir, General Dynamics Fighting Falcon and IAI Sea Scan aircraft. The basic Gabriel Mk III A/S version has a range of 40 km (25 miles) whilst the Gabriel Mk III ERA/S extended-range version has a lengthened sustainer motor with­in the existing body to give a range of 60 km (37.3 miles). Both have the same capabilities for fire-and-forget and fire-and-update launch modes as the Using a variety of command-guided and semi-active homing techniques, the Gabriel Mk I was used extensively in the 1973 Yom Kippur War by the Israeli navy andsanka number of Syrian and Egyptian craft. original Gabriel Mk III. Only Israel operates the air-launched Gabriel Mk III models. The Gabriel is known to be built under licence by two countries South Africa (as the Skorpioen) and Taiwan (as the Hsiung Feng or male bee).
