Aspide (the Italian name for the asp) is an Italian medium range air-to-air and surface-to-air missile produced by Selenia (then by Alenia Aeronautica, now a part of Leonardo S.p.A.). It is provided with semi-active radar homing seeker. It is very similar to the American AIM-7 Sparrow, using the same airframe, but uses an inverse monopulse seeker that is far more accurate and much less susceptible to ECM than the original conical scanning version.
This resemblance, and that Selenia was provided with the technology know-how of the AIM-7 (around 1,000 of which it had produced under licence), has generally led non-Italian press to refer to the Aspide as a Sparrow variant. However, the Aspide had original electronics and warhead, and a new and more powerful engine. Closed-loop hydraulics were also substituted for Sparrow's open-loop type, which gave Aspide better downrange maneuverability. Even the control surfaces are different, replacing the original triangular wings, fixed in the air-to-air and instead foldable in the surface-to-air version, to a newly designed common cropped delta fixed version.
A similar design is the UK's Skyflash, which entered service about the same time. The US's own Sparrow fleet also added a monopulse seeker in the AIM-7M versions of 1982.
Aspide, in its various versions, was used both in the air-to-air role, carried by Aeritalia F-104s in the apposite versions F-104S and F-104ASA, and in the surface-to-air naval role. In the latter role it has been replaced by the MBDA Aster. Naval Aspide launchers can be adapted to fire the Sparrow by merely switching a single circuit board.
In the mid 1980s, China imported a small batch of the Aspide Mk.1 from Italy, then signed an agreement with Alenia to produce the missile locally under license. In 1989, China produced its first batch of Aspide Mk.1 missiles using imported parts from Italy. However, due to the EEC arms embargo imposed after the 1989 Tiananmen Square protests and massacre, China was unable to purchase additional Aspide kits. [1] China subsequently developed its own missile family based on the Aspide Mk.1, with surface to air versions designated as the LY-60, and an air-to-air version designated as PL-11.
The rocket engine of the Aspide is produced by Turkish missile manufacturer Roketsan. [2] It weighs about 75 kg and produces 50 kN of thrust for 3.5 s.
The AIM-7 Sparrow is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM.
The Maestrale class is a class of frigates of the Italian Navy. The class is composed of eight vessels, all of which were built by Fincantieri S.p.A., Riva Trigoso, except for Grecale, which was built by Fincantieri S.p.A. – Muggiano, La Spezia.
RIM-7 Sea Sparrow is a U.S. ship-borne short-range anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a lightweight "point-defense" weapon that could be retrofitted to existing ships as quickly as possible, often in place of existing gun-based anti-aircraft weapons. In this incarnation, it was a very simple system guided by a manually aimed radar illuminator.
The Libyan Navy is the naval warfare branch of the Libyan Armed Forces. Established in November 1962, Libyan Navy has been headed by Admiral Mansour Bader, Chief of Staff of the Libyan Naval Force. Before the First Libyan Civil War it was a fairly typical small navy with a few missile frigates, corvettes and patrol boats to defend the coastline, but with a very limited self-defence capability.
The OTO Melara 76 mm gun is a naval autocannon built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales.
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves. The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries.
The RBS 15 is a long-range fire-and-forget surface-to-surface and air-to-surface anti-ship missile. The later version Mk. III has the ability to attack land targets as well. The missile was developed by the Swedish company Saab Bofors Dynamics.
The Algerian Naval Force is the naval branch of the Algerian military. The naval force operates from multiple bases along the country's nearly 1,440 km (890 mi) coastline, fulfilling its primary role of monitoring and defending Algeria's territorial waters against all foreign military or economic intrusion. Additional missions include coast guard and maritime safety missions as well a projection of marine forces. Algerian forces are an important player in the Western Mediterranean.
The Laksamana class is a class of small missile corvettes comprising four ships currently in service with the Royal Malaysian Navy. All four ships of the Laksamana class are currently serving in the 24th Corvette Squadron of the Royal Malaysian Navy.
The Otomat is an 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 and, for the later versions, Teseo, from the Italian word for Theseus. The MILAS variant is an anti-submarine missile. In its latest version Mk/2E purchased by the Italian Navy is a medium range anti-ship missile and a ground attack missile.
The MEKO 360 is a class of five ships built in Germany for the Argentine and Nigerian navies. The MEKO 360 was the first version of the MEKO family of vessels built by Blohm und Voss. The type comes in two variants, the MEKO 360H1, comprising one ship, and the MEKO 360H2, comprising four ships. They are alternatively classed as frigates and destroyers by different sources. The design is based on the modular concept which allows swapping out different armaments to fit mission requirements and allows for easier application of upgrades and refits.
The Durand de la Penne class are two guided-missile destroyers operated by the Italian Navy. The design is an enlarged version of the Audace class, updated with diesel and gas turbine CODOG machinery and modern sensors. Four ships were planned but the second pair were cancelled when Italy joined the Horizon project.
The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems. It is tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems, or for use as gap-fillers in a larger air defense system.
The Inhaúma class are a series of five corvettes operated by the Brazilian Navy. These ships were built in Brazil and designed with assistance from the German company Marine Technik. It was originally planned to build 12 to 16 ships but the economic situation in Brazil did not permit this and only five vessels were built. The first two ships were constructed at the Arsenal de Marinha in Rio de Janeiro, the second pair by Verolme. The programme was considerably delayed due to funding issues and the Brazilian Verolme yard's insolvency in 1991 which forced Júlio de Noronha and Frontin to be completed by Arsenal da Marinha. The first ship entered service in 1989 and the last in 2008. Three of the five ships have been taken out of service and one was sunk in a missile exercise in the Atlantic Ocean in 2016.
The CAMM is a family of surface-to-air missiles developed by MBDA UK for the United Kingdom. CAMM shares some common features and components with the ASRAAM air-to-air missile, but with updated electronics and an active radar homing seeker.
The MEKO 200 is a frigate design by the Blohm + Voss shipyard of Germany, as part of the MEKO family of warships.
SMART-S Mk2(Signaal Multibeam Acquisition Radar for Tracking, S band Mk2) is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal). While the original SMART-S radar was only produced in small numbers, SMART-S Mk2 is very successful. Only six years after its introduction, 30 systems were sold to navies all over the world. SMART-S Mk2 radar is equipped with transmitter/receiver (T/R) modules manufactured by Turkish defence company Aselsan. The radar transmitter/receiver (T/R) modules for the radar are purchased by Thales from Aselsan.
