 for over-the-horizon targeting, which limited its effective range to 60 km, a similar figure to the Exocet. To solve this problem, development of a Mk2 version started in May 1973, with a first test launch in January 1974, development completed in 1976, and the first over-the-horizon launch in 1978.. By the end of 1976 OTO Melara had reported that 210 Otomats had been sold: Italy 48, Peru 40, Venezuela 12, and Libya 110. Also at this time there were negotiations under way for the sale of 296 more missiles to various nations (i.e. Italy 48, Egypt 30, Venezuela 48, Libya 120, Indonesia 50).

A Mk2 Block II version was introduced in the 1980s, it featured folding wings so that the missile could now fit in a smaller launch boxes. This reduction in size allowed a doubling in the number of missiles carried, usually from four to eight. Even so, Otomat Mk2 Block II remained bulkier than contemporary versions of Harpoon and Exocet missiles due to its greater diameter and its boosters being fitted to its flanks instead of in the rear.

 box which weighs 1,610 kg fully loaded. This container has a rectangular shape to accommodate the fixed wings of the missile and an inclination of 15 degrees. At launch, the boosters propel the missile up to a height of 200 m before the main engine starts and a descent to 20 m is made. Otomat Mk2 missiles have a data-link for mid-course updates. They are designed to strike their targets in a 180 m dive or in a sea-skimming mode at an altitude of 2 m with a 210 kg warhead capable piercing up to 80 mm of steel. The warhead is designed to explode inside the ship with the force of the explosion directed to the bottom of the target ship.

Technical data are: 4.46 m length, 40 cm diameter, 1.35 wingspan, 770 kg launch weight.

The mid-fuselage fuel tank has a capcity of 90 liters, behind the fuel tank is the TR-281 ARBIZON III engine, a simple turbo-jet. The twin ROXEL boosters weigh 75 kg each, and provide an acceleration of 6 g for four seconds.

The Turboméca TR.281 Arbizon III is a jet engine of 400 kg/t., around 50% more powerful than the Harpoon's engine, the Willis turbojet that has 272 kg/t. This latter engine is apparently used also on the bigger BGM-109 so this has lower speed (around 800 km/h compared to 1,000). Air intakes are an unusual number, four, all placed forward the wings, at mid-fuselage (as example Harpoon and Tomawhak have only one), contribuing to the characteristic, complex shape of this missile.

Power available has made possible to fit in the bulky fuselage a high fuel reserve, heavy warhead and a data-link (Mk 2 model) to receive updates, at least once when in flight to the target.

The flight controls are four foldable stearable main wings, and four tail control winglets. Structure is made of light alloys, mainly aluminium

 is in the front, behind the radar section and forward the radio-altimeter and some other electronic systems. The HE warhead is of the semi-armour piercing type and has a 65 kg Hertol type filler (for comparison, Kormoran missiles have 165 kg warheads, 56 kg is the HE main charge, plus 16 radial small charges to explode well inside the ship after the main explosion, and the armour piercing capability is around 7–8 cm).

In a typical layout, there are 4-8 fiber-glass boxes, with the missile inside, held by a rail in the roof. The overall weight is 1,610 kg.

Data-links are included in the TESEO or ERATO control systems. ERATO has computerized consoles CLIO, while TESEO has MM/OJ-791 consoles, weighing 570 kg with 4 kW electric power requirement. The Data-link is called the PRT400 system, and the components are the PTR402 designation for missile (as receiver), PRT401 designation for the transmitter (shipborn) or PTR403 (carried by helicopter). Other systems fittable are PRT404 system for light ships and PRT405 system for helicopters.

Overall strengths of this missile are long range, speed, sea-skimming capabilities and a powerful warhead.

Weakness are the need for a helicopter for mid-course guidance and a quite difficult uplink in the TESEO system (at least in the original model), big dimensions (affecting radar cross section RCS and IR signature), the lack of complex manoeuvres (synchronization of attacks, re-engagement capabilities, ECCM capability not up to current standards and never publicized), and the availability of surface versions only: no submarine and aircraft versions were developed.

This caused problems to the services that acquired these anti-ship missiles: Italian forces use Otomat (ships), Marte (helicopters), Kormoran

 (not confirmed for submarines). Given the necessity to buy other totally different missile systems, many customers simply bought a 'family of missile systems' as in the Harpoon series and the Exocet family with obvious operative and economic advantages.

Typical mission

In terms of technology and operability, this missile, while almost unknown the general public having not been involved in a war, presents a very powerful anti-ship weapon and perhaps the most powerful of all modern western anti-ship missiles having a mid course data-link.

No particular manoeuvres are required by the ship: the missiles are capable of changing course after the launch up to 200° so all the missiles in the ship could be used against the same target

 in one attack.

This allows for quick reaction times as the ship does not need to change direction to unmask the missile batteries. This allows the ship to fire all missiles against a target regardless of where they are place aboard.

Flight

The boosters made by ROXEL, are positioned at the flanks, gives enough speed allowing the turbojet to start, while the wings opens, then the missile reach in 4 seconds 250 m/s speed and 200 m height
Height
Height is the measurement of vertical distance, but has two meanings in common use. It can either indicate how "tall" something is, or how "high up" it is. For example "The height of the building is 50 m" or "The height of the airplane is 10,000 m"...

 and descends to 20 m cruising at low altitude. At this time the auto-pilot and the altimeter make possible hold the right directions to the target. The missile flies at around 1,000 km/h controlled with the four cross winglets in the aft, behind the main fixed wings to sustain the weapon.

Mid-course update is possible with several systems. This weapon system is called TESEO (only the missile is called Otomat) in the Italian Navy, and the mid-course is given with two channels: by the ship itself (TG-1) and with external sources, available in the Agusta Bell AB-212 ASW helicopter's final production batch, that uses TG-2.

While the missiles flies it receive the input at mid-course, then, at only 6 km from the target activates the onboard radar to reduce reaction time from the target. This could be of two models: the simpler ST-2 made by SMA (Italian missiles) and the more complex and ambitious CSF 'Col vert', for French made missiles (only for export, since the French Navy had not adopted them). There is a large difference in the seekers, because the first is a one axis, two dimensional radar system: the weapon simply continues to fly to the ship, with the altitude falling from 20 to, in good sea conditions, 2-3m. The warhead is heavy, 210 kg (Exocet 165, Harpoon 227) and the explosive blast is focused downward, attempting to blast a hole in the ship bottom sinking rather than just damaging the vessel. The Col Vert version of the missile performs pop up flight to 180 m at around 2 km from the target and then dives on the ship, aiming at the decks to maximise damage..

The Col Vert version seems to have suffered problems in service with issues from sea state wave clutter. The popup and final dive attack the Col Vert version of Otomat were designed to fool CIWS fire solutions. A similar approach was used in the US Harpoon system, then abandoned. Sensors in this variant are more complex and costly than the simpler sea skimming models, and while more capable to penetrate air defences, they may have not shown a decisive superiority, even if tecnologically more sophisticated.

Mid-course datalink

The mid-course data uplink was originally provided by two different systems: TESEO and ERATO.

The ERATO (Extended Range Air Targeting for Otomat) system, used by the Al-Madinah class frigates, is the French version for mid-course guidance of the Otomat missile. In this case updated target information is provided to the ship which controls up to 16 missiles. This allows a multi-ship launch (Madinas have eight missiles each) and single ship control of an Otomat salvo for coordinated attack. The downside of this system is that the Otomat missile must rise to a 900 meter altitude to achieved uplink data. This could theoretically warn a target ship of the impending attack, but there are few possibilities to notice such small missiles at ranges of more than a few dozen kilometers.. Maximum range for data-link is 100 km, limiting somewhat the missile's maximum range. It is possible to send up to six corrections for each missile, and attack up to six differently targets at once. Consoles are called CLIO, integrated with ship's combat system.

TESEO is used by the Italian Navy Marina Militare

 (MMI or MM) and not allowing updated from the ship, do not needs altitude variations in the flight for missiles.

The limiting factor with the Otomat as incorporated in the TESEO system is that the AB-212 ASW Helo platform used for update has a limited radar range of no more than 60 km (with a 2,000 m2 RCS target, typically a frigate or destroyer), and will be hovering and stationary to allow the missile to fly under it and guide Otomat to its target.

 suites), the AB-212 helo's lifespan could be limited to mere seconds, as it is much bigger than anti-ship missiles.

TESEO system requires that the missile fly under the helicopter, allowing the engagement of only one target at a time (even if with two missiles), the missiles must be launched to helicopter and so, this one must fly practically fixed for several minutes, while the missiles must fly a longer flight path, being this launch a non linear flight path.

In addition the AB-212 helo is old, slow and vulnerable to any air platform with even minimal AAW capabilities. AB-212ASW speed is listed at 196 km/h, slower than the land model AB 212, with 185 km/h max. cruise speed. The other widespread naval helicopters, Westland Lynx

 and Sikorsky Seahawks are all far faster and the four blades rotor allows very good agility, compared to the old two blades rotor. Concern is also centered around ECM measures against older weapons system with a relatively primitive uplink system. A further complication is that the AB-212 will take up to an hour to reach Otomat's maximum range (in the meanwhile, a jet interceptor can fly easily for more than 900 km), as time in combat is a valuable commodity. All these problems are at least partially solved in Madina' frigates, that have ERATO data link system and AS-365 Dauphin helicopters, capable of almost 300 km/h.

Developments

A version called Otomach was proposed as a further improvement on the Mk2, with a speed of Mach

 1.8. However, further evaluations found that stealth was better than speed at penetrating warship defenses so the project was dropped. In 1992, the Italian government started the development of a new generation anti-ship missile designated Otomat Mk3 with a disbursement of 19 million. Meanwhile, the French Navy chose to pursue the ANS/ANNG/ANF project for a supersonic missile, thereby ending French involvement in the development of the Otomat.

The Mk3 version was named at one point Ulisse, the Italian name for the mythical hero Odysseus

. With development starting twenty years after the Mk1 version, the Mk3 was a quite different weapon. The guidance package was updated with new IR and radar sensors in the nose, a GPS navigation system and an updated data link to allow the engagement of coastal targets. To improve the missile chances of hitting, its nose and wing shapes were optimized for a reduced radar cross section

The latest version of the Otomat is the Mk2 Block IV, also called Teseo Mk2/A. It has a new data link which allows its flight to be controlled from the ship via the Teseo system in a similar way to Erato. GPS is also fitted allowing programmable flight trajectories with complex paths. The Italian Navy ordered 38 missiles of this version, 27 for operational use and 11 for training purposes with an estimated in-service date of 2008.

A separate path led to the development of Milas, an anti-submarine variant of the Otomat. It started in 1986 as a Franco-Italian program for a missile capable of delivering a lightweight anti-submarine torpedo

It can put a torpedo in the water at 35 km of its launch platform within three minutes and, if required, change its impact point while flying. Only a few Milas missiles are in service, deployed on the two Durand de La Penne class destroyer

The only other variant in service is a coastal defense version bought by Egypt and Saudi Arabia, and ordered by Iraq but never delivered to that country. All necessary electronics are trailer-mounted as well as twin missile launchers, which makes it a high mobility system. Even so, Iraq had planned to deploy it in fixed armored sites..

Testing and the future of Otomat

Thare is no known combat use of Otomat but there were many tests, like the one happened in 1987, when a Venezuelan Lupo frigate hit an old US destroyer used as target at 122 km, leaving a 6 m hole in it. Flight took a little over than 400 seconds. In another example at least 8 missiles were bought by US Navy: thanks to a new evasive, final maneuver, the majority of these weapons, called LRAT (Long Range Attack Target) penetrated inside the formidable missile defenses of US ships.

In all by all, this missile was and is a very powerful weapon. Without helicopter provided mid-course guidance (especially in presence of enemy fighters), this weapon is still capable of striking well over the horizon. A range of 50 km can be covered with the ship's sensors and missiles like MM.38 Exocet are at their optimum. Between 50–120 km is the range that weapons like Harpoon

, which have over the horizon capabilities but no data-link update, come into play. At ranges longer than that a target moving in unpredicted directions will give such weapons little or no chance to acquire their target. Finally, over 120 km is where the need for a long range weapon, external targeting platforms and data-linked updates come into play as only with course and target position updating can any long range missile have a chance of engaging a moving target at these ranges. This is the typical capability of the Otomat and long range soviet missiles. In short range engagements, the Otomat does not have any advantage since it is bigger than other missiles and presents a larger target to shoot down.

The possibilities of commercial success are not good today, since this weapon is related mainly with the operation Italian warships, now not so much of a commercial export success as in previous decades. The management of both the missiles-Exocet and Otomat are now under the MBDA company control, so while in actually in competition with one another Otomat has fared worse in the world's market place to the famous and combat proven Exocet under the MBDA firm..

MILAS was conceptualized when the USSR was the main threat, during the Cold War. After 1991, the necessity to have outstanding ASW weapons systems was seen as being reduced with many ex USSR submarines rusting beside piers, and so MILAS is not destined to be a widespread weapon either, despite it is fully adaptable to the standard launch system used for Otomat.

 navigation system, 'insensible' warhead, new, safer solid propellent for boosters, improved data link to allow TESEO to guide missiles also from the ship directly. It is not known when it entered service.

Otomat Mk 3/NGASM/ULISSE: new version with longer range, stealth design (both shape and materials), IRST sensor coupled with the radar and GPS, land attack capabilities. Development started at the beginning of '90s. The US Navy was interested but didn't adopt the system and the Italian Navy abandon the project the cost being too high for Italian navy alone.

 version with a light torpedo in the nose, 55 km range and compatibility with Otomat standard systems. The MILAS program started in the '80s, and was finally adopted only by Italian Navy, the French Navy withdrawing from the program to due to cost.

Otomat Mk 2 Block IV: latest version, also called Teseo Mk2/A (for the Marina Militare), with a new electronic set, partially derived from Marte Mk 2/S missile program. 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. Currently it is available on the export market and has been purchased by export customers in 2008.
