# Aspide

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.

## Design

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 In the latter role it has been replaced by the MBDA Aster.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. 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. It weighs about 75 kg and produces 50 kN of thrust for 3.5 s.

## Variants

* Aspide Mk.1 – Similar to AIM-7E, with Selenia monopulse semi-active seeker and SNIA-Viscosa solid-propellant rocket motor. This version was popular with export customers, and sold to 17 countries. The surface-to-air systems are Skyguard and Spada.
* Aspide Mk.2 – Improved version with active radar-homing seeker. Development was shelved in favor of better missiles, such as the AIM-120 AMRAAM.
* Aspide 2000 – Improved surface-to-air version of the Aspide Mk.1, used on export Skyguard and Spada 2000 air-defense systems.
* Aspide Citedef – Surface-to-air version of the Aspide Mk.1 upgraded by Citedef.

## Systems

* Skyguard I – VSHORAD/SHORAD from Oerlikon Contraves with radar tracking, upgradeable to support Aspide 2000.
* Skyguard II – Improved VSHORAD/SHORAD from Oerlikon Contraves with added electro-optical tracking.
* Toledo – Skyguard with Skydor fire control system from Navantia and Aspide launchers.
* Spada – SHORAD from Selenia with Selenia PLUTO 2D radar, upgradeable to support Aspide 2000.
* Spada 2000 – Improved SHORAD from Alenia Aeronautica with Thomson-CSF RAC 3D radar.
* Albatros Mk.2 – Naval SHORAD from Selenia, upgradeable to support Aspide 2000.
