OVERVIEW: Generic Missile Illuminator & Gun Directors (radar-based) are dual-purpose fire-control radars used for both missile target illumination and gunfire control. Widely deployed since the 1950s, they provide continuous tracking and engagement support for naval and ground-based systems.

GENERAL DESCRIPTION: These systems are radar-based fire-control sensors that support surface-to-air missiles using continuous wave (CW) or monopulse illumination and also direct gunfire against aerial or surface targets. Typically integrated into larger air defense or naval combat systems, they track targets with high precision, provide angular coordinates, and cue both missile seekers (e.g., SARH) and gun mounts. They often form part of close-in weapon systems (CIWS) or medium-range air defense networks and are capable of operating under heavy ECM conditions depending on generation.

ROLE SUMMARY:
Category: Fire Control Radar
Primary Use: Missile illumination and gunfire direction
Function: Target tracking, illumination for SARH missiles, ballistic solution for guns
Platform: Surface ships, ground-based air defense systems, armored vehicles
Integration: Linked with radar, electro-optical systems, missile launchers, and gun mounts
