The ROKA K-SAM Pegasus

The Crotale EDIR (Ecartométrie Différentielle InfraRouge, “InfraRed Differential Ecartometry”) is an all-weather short-range anti-air missile, which can be used to intercept low-flight anti-ship missiles and aircraft.

In 1999, the Republic of Korea Armed Forces awarded a contract to Samsung Thales to jointly develop a South Korean-augmented Crotale NG system for the K-SAM Pegasus short range air defence system.

A new search-and-track radar was jointly developed by Samsung and Thales to meet the required operational capability of the K-SAM Pegasus, as well as a new indigenous missile by LIG Nex1. Doosan DST integrated this modified Crotale NG system with a ROKA K-200 IFV hull/chassis AKA the K-21.

It was designed to engage airborne threats flying at altitudes of 5,000 meters and ranges of 9-10km  using Command-to-Line-Of-Sight (CLOS) guidance.

The surveillance radar is capable of detecting up to 20 airborne targets at ranges up to 20km. The tracking radar can track up to eight targets at ranges of 16km. The air defence system is workable in day/nigh and all-weather conditions in heavy clutter and jamming environments. The 26-ton V-shaped chassis is powered by a Doosan D2840L 10V turbo-intercooled diesel engine rated at 520-hp.

48 units were initially produced for 330 million Euros. A second batch of 66 units was ordered in 2003, valued at 470 million Euros.
