Marte (missile)

Sea Killer is an Italian anti-ship missile family. The latest development of the system is known as Marte. Marte is a sea skimming, subsonic, anti-ship missile, it carries a semi-armour piercing warhead. It has been built in several versions, with differing guidance systems, and is suitable for launching from ships or aircraft.

Sea Killer was initially developed during the 1960s and has been deployed by at least six countries. It was used during the Iran–Iraq War, with at least six ships being hit.

Development and design

Contraves Italiana, an Italian subsidiary of the Swiss armaments company Oerlikon Contraves, began development of a short-ranged - - ship-based anti-ship missile system, named ''Nettuno'' in 1963. Guidance of Nettuno was by beam riding for course control, with altitude controlled automatically by an onboard radar altimeter, allowing the missile to carry out sea-skimming attacks. Command guidance was an alternative guidance method if jamming made the beam-riding method unusable. In 1965, Contraves Italiana began work on an improved missile, ''Vulcano'', which used the same guidance system, but included a two-stage (booster + sustainer) rocket motor to give a longer () range. Both missiles could be fired from a five-round trainable launcher.Pretty and Archer 1972, pp. 42–43.Pretty 1977, pp. 61–62.

Testing of ''Nettuno'' began in 1966,Pretty 1977, p. 61. with a trial installation being made on the Freccia-class patrol boat ''Saetta'' of the Italian navy, with the five-round launcher replacing a Bofors 40 mm gun.Moore 1979, p. 279. Testing of ''Vulcano'' began in 1969.

In 1967, the Italian company Sistel (''Sistemi Elettronici'') was set up as a joint venture by five Italian companies, including Contraves Italiana, and the missile division of Contraves Italina was transferred to Sistel, along with the ''Nettuno'' and ''Vulcano'' missiles in 1969.''Flight International'' 25 January 1973, p. 135. ''Nettuno'' and ''Vulcano'' were renamed Sea Killer Mark 1 and 2 respectively for export, and these names gradually replaced the older names.Pretty and Archer 1972, p. 42.

Sea Killer Mark 2 was purchased by Iran to arm its ''Saam'' class of four frigates, each of which was fitted with a single five-round launcher.Moore 1979, p. 155. No other sales of the ship-based version were made,"Sea Killer/Marte (Italy), Surface-to-surface missiles"
''Janes.com''. 2009. Retrieved 8 April 2012. but development of Sea Killer Mark 2 into an all-weather anti-ship missile to equip the Italian Navy's helicopters began in 1967,Gunston 1983, p. 110–111. with the helicopter-based weapon system being named ''Marte''.Pretty 1977, pp. 141–142.

''Marte'' entered service with the Italian Navy in 1977, with its Sikorsky SH-3 Sea Kings being fitted with two Sea Killer Mark 2 missiles.Freidman 1997, p. 231. In 1983, a new version, Marte 2, was announced, with the beam-riding guidance replaced by an active radar homing seeker based on that used by the Otomat anti-ship missile.''Flight International'' 1 October 1988. Testing of Marte 2 started in 1984, and the missile entered service with the Italian Navy in 1987.

The Marte ER, an improvement on the missile family, replaced the rocket motor with Williams WJ-24-8G turbojet propulsion and added a new ISO-caliber cylinder cell, which made it shorter in length but extended its range to over . Fitting trials of the Marte-ER onto the NH90 helicopter, which can carry two missiles, occurred in June 2014; a larger anti-ship missile like the Exocet was rejected for integration as physically too long and heavy.

In November 2015, a Eurofighter Typhoon was fit-tested for a fixed-wing version of the missile called the Marte-ERP, which does not feature folding fins and sheds the booster for a larger 120 kg (265 lb) warhead with penetrating and sector-blast properties; though smaller than other options like the Harpoon and RBS-15, a fighter like Eurofighter Typhoon can carry six Marte-ERPs (or four with fuel tanks) compared to two or three larger missiles.NHIndustries and MBDA started integration of MARTE ER missile on NH90 maritime helicopter

The Marte ER completed its final test firing in November 2021. Full-scale production began in late March 2022 and it then began deliveries to its launch customer, the Qatari Emiri Navy.

Operational history

Iran's Sea Killer Mk 2 saw combat service during the Iran–Iraq War, being used to attack merchant shipping in the Persian Gulf, with at least six ships being hit.
