Gabriel - IAI / MBT began to develop the first sea to sea missile in 1962, and revealed to public at first time in 8.5.1970. 

This challenge was met with the development of an original approach to missile guidance, resulting in the creation of the Gabriel - the world's first operational, sea-skimming missile. 
The Gabriel missile system gave the Israel Navy an unprecedented combat capability as demonstrated during the 1973 Yom Kippur War

Missile upgrading - A cost-effective way to extend the life of a missile system is to upgrade its guidance system. IAI's Electronics Group / MBT has employed this technique in different missile systems, using various types of seekers based on advanced signal processing techniques, artificial intelligence, multi-tasking, multi-processing, and secure communication systems. 

Advanced Missiles - MBT is currently developing the next generation of naval missiles and weapon control systems, utilizing the most sophisticated concepts. The new missile will be able to penetrate both softkill and hardkill defenses.

Gabriel III
 

Gabriel Mk 3 A/S
 
The Gabriel has been successively updated to the current "Gabriel III" missile, with twice the range and a substantially different external appearance from the Gabriel I. It is available in both ship-launched and air-launched versions, with the air-launched version known as the Gabriel III "A/S" (Air to Surface). 

The Gabriel III A/S is powered by a stubby cruciform wings fitted to the midsection and cruciform tailfins for guidance. It has boost-sustain solid rocket motor and is fitted with a SAP warhead. 

While the Gabriel I used a semiactive radar homing seeker that required the launch platform to keep the target illuminated by radar, the Gabriel III has a dual-mode seeker that can be operated in "fire and forget" or "fire and update" modes. 

In the "fire and forget" mode, the Gabriel III is guided by an INS into the target area, with altitude maintained by a radar altimeter. It then turns on its active radar seeker to lock onto and attack the target after a search. In the "fire and update" mode, the missile can receive course corrections from the launch aircraft while it is cruising towards the target, allowing it to keep its radar seeker off until the last moment. 

The Israeli Gabriel III A/S is an advanced offshoot of the original Gabriel ship-to-ship missile system. The original Gabriel was a small, canister fired sea skimmer, designed to attack enemy vessels at wavetop level, making its approach extremely hard to detect. This newer, air-launched version is larger, with a range of 60+ km, and carries a high-explosive warhead weighing 150 kg. The guidance system of the Gabriel III/AS enables it to fly so low that it must be pre-set according to the current size of the waves.

Gabriel IV
 
 
There is apparently a new long-range turbojet-powered version of the Gabriel, the "Gabriel IVLR", and some sources state that Denel of South Africa has also built a 150 kilogram submunition warhead for the Gabriel. This unusual warhead has a main charge and 35 fragmenting submunitions that detonate in sequence at 5 millisecond intervals, with the fragments heavy enough to penetrate bulkheads.

Gabriel Mk IIIA/S 
: This is the air-launched version of the ship-launched Gabriel Mk III anti-ship missile, itself derived from the earlier Gabriel Mks I and II.
 
The Gabriel Mk I was developed in the 1960s as a missile with a range of 11.3 nm (13.05 miles; 21 km) and optimization for deployment on fast attack craft, while the Gabriel Mk II introduced a longer body for more fuel as a means of boosting range to 19.5 nm (22.4 miles; 36 km). The ship-launched Gabriel Mk III introduced a frequency-agile active radar seeker, although the optical and semi-active radar homing systems of the Gabriel Mks I and II can also be used to provide greater tactical flexibility and continued operability in the face of enemy ECM.
 
The Gabriel Mk III can thus have three guidance modes, namely fire-and-forget, fire-and-update via a data link from a targeting helicopter, and fire-and-command using the launch vessel's radar for better targeting data. The missile cruises at 330 ft (100 m) and then descends to 66 ft (20 m) for its approach to the target, the attack phase being flown at a height preset height of 4.9, 8.25 or 13.1 ft (1.5, 2.5 or 4 m) depending on the anticipated sea state in the target area.
 
The Gabriel Mk IIIA/S is the air-launched version of this weapon with a slightly longer body, reduced-span wings and lighter weight, which all contribute to higher speed but shorter range. The missile has three operating modes: range-and-bearing launch using radar-derived data, range-and-bearing launch using manually entered data, and bearing-only launch.
 
In its basic layout the Gabriel is of typical anti-ship missile configuration, with a cylindrical body terminating forward in the ogival nose come that constitutes the radome for the active radar guidance’s antenna, a mid-set cruciform of fixed wings, and a tail-mounted cruciform of moving control fins indexed in line with the wings.
 
Gabriel Mk IIIA/S ER : This is an extended-range version of the Gabriel Mk IIIA/S with a longer sustainer rocket that increases weight to 1,322.75 lb (600 kg) and maximum range to 32.4 nm (37.3 miles; 60 km), which is about that of the ship-launched Gabriel Mk III variant. Both the Gabriel Mk IIIA/S and Mk IIIA/S ER have the same guidance options as the basic Gabriel Mk III as detailed for the Gabriel Mk IIIA/S.
 
Gabriel Mk IVLR : This is an updated version developed during the early 1990s for a service debut in the middle of the decade. Although it is clearly related to the Gabriel Mk III, the Gabriel Mk IV is a somewhat larger and more massive weapon with turbojet sustainer propulsion for longer range with a more potent warhead.
 
The Gabriel Mk I has a diameter of 1 ft 5.3 in (0.44 m), length of 15 ft 5 in (4.70 m) and span of 5 ft 3 in (1.60 m), weighs 2,116.4 lb (960 kg) with its 529.1 lb (240 kg) proximity- and impact-fused semi-armor-piercing blast/fragmentation warhead, and its propulsion arrangement uses a solid-propellant rocket for the boost phase and a small turbojet for the sustain phase of the mission, which can extend to a range of 107.9 nm (124.3 miles; 200 km).
 
The Gabriel Mk IV has the same basic configuration as the Gabriel Mk III with the exception of its wings, which are changed in shape from trapezoidal to swept with cropped tips. The missile has the same guidance options and attack modes as the Gabriel III.
 
There are no known exports of the Gabriel anti-ship missile in its air-launched forms.
