The Otomat Mk 2 Block IV is latest version Otomat missile system. Enhanced version of the all weather OTOMAT MK2 missile system, providing improved performance in terms of OTHT (Over The Horizon Targeting) and operations in complex naval scenarios. Capable of ranges from 6 to 180 km in all directions, the system relies on powerful mission planning (3D way-points, terminal sea skimming profile, simultaneous attack from different directions). Target data is derived from the ship’s Command System or taken directly from the ship’s surface search radar. Mission Planning allows the selection of different firing modes (such as Fire and Forget or midcourse guided) and of specific trajectories and evasive manoeuvres.
The Otomat Mk 2 Block IV also called Teseo Mk2/A (for the Italian Navy), with a new electronic set, partially derived from Marte Mk 2/S missile program. Cruise and approach phases may be either fully inertial or partially guided from the launch ship through a radio-link. Mid course re-vectoring from a co-operating ship or helicopter is also possible. The excellent capabilities of the new missile (short reaction time, Fire and Forget, INS/GPS navigation, high target selection, ECCM and anti-CIWS manoeuvres, warhead lethality with no collateral damage) allow the system to operate effectively in littoral warfare environments, as well as in blue waters. The terminal attack phase is based upon an autonomous terminal guidance using an active homing head with improved target selection capabilities in complex scenarios.
The TG-2 (data-link for helicopters) is abolished, because the ship is capable to guide the missile directly (as happened with ERATO) with information given by external platform with OTH engagements. The missile is capable of: re-attack, 3-D mission planning, coordinate attacks, capability to operate in littoral theaters, and attack with terminal evasive maneuvers. GPS is added and so the weapon can attack also land targets. In May 2006, Teseo MK2/A was successfully test-fired for the first time. This variant will in due course be deployed on the Italian variant of the Franco-Italian FREMM frigate. Teseo MK2/A has entered service with the Italian Navy in 2007. Available on the export market and has been purchased by export customers as of 2008.
The Otomat is a short-range subsonic anti-ship and coastal defence missile developed by the Italian company Oto Melara jointly with Matra and now made by MBDA. The name comes, for the first versions, from the name of the two builders (OTO Melara MATra) and, for the later versions, Teseo, from the Italian word for Theseus. The MILAS variant is an anti-submarine missile. 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.
