S1850M

The S1850M is a long-range radar with a digital antenna array for wide area search in elevation.

It is also claimed to be highly capable of detecting stealth targets, and able to detect and track outer atmosphere objects at short range, enabling it to form part of a Theatre Ballistic Missile Defence system.

The contract for initial production of the S1850M was signed in 2001: two for the UK, one for France, and one for Italy, with a common prototype based in Toulon.

[1] In all its current applications, the S1850M is the long-range radar (LRR) component of the Principal Anti-Air Missile System.

On 11 February 2009, Thales indicated that the S1850M radar will be fitted on the Royal Navy's Queen Elizabeth-class aircraft carrier.
