esto es detalle de la performance del Sea Dart
estos son las versiones Pre y Post Malvinas...
Originally, in the Type 22 and Sea Wolf equipped Leander class, this was the radar Type 967 / 968 combination; the D-band Type 967 providing long range surveillance and the E-band Type 968 providing short range target indication. Latterly, these functions have been taken over by the radar Type 996 3D surveillance radar.
Originally the Type 910, with a dual-role I/J band radar, was used but this suffered from poor performance locking onto low-altitude targets hidden in the background sea clutter in the Malvinas War. Subsequently, the lighter Type 911 supplanted the Type 910, with a separate I-band radar to gather targets and K band radar to provide the lock. This system is based on the Blindfire tracker of the Rapier missile and was fitted in the 7th Type 22 Frigate onwards. Unlike Type 910, Type 911 is not reliant on the CCTV function, although this is retained as a back up and to provide a record of engagements.
esto es detalle de la performance del Sea Dart
Sea Dart was found to be unsuitable when operating close inshore as it was unable to lock onto targets at distance obscured by land and fast-moving low-level targets obscured in ground clutter or sea-returns. These shortcomings were more damning of the Type 42 destroyer than Sea Dart itself, as the former were fitted with obsolete 1950s-era radar Type 965 and had no other defence against aircraft apart from a pair of World War 2-vintage 20 mm guns.
estos son las versiones Pre y Post Malvinas...
* Mod 0 — Basic 1960s version, used in the Malvinas. Vacuum-tube technology. Range circa 40 nm.
* Mod 1 — Improved Sea Dart. Upgraded version 1983-1986. Updated guidance systems possibly allowing some capability against sea-skimming targets and much greater reliability.
* Mod 2 — 1989-1991. Upgrade included ADIMP (Air Defence IMProvement) which saw the replacement of six old circuit cards in the guidance system with one, allowing the spare volume to be used for an autopilot. Used alongside a command datalink (sited on the Type 909 pedestal) it allows several missiles to be 'in the air' at once, re-targeted during flight etc. and allows an initial ballistic trajectory, doubling range to 80 nm with the upgraded 909(I) radar for terminal illumination only.
* Mod 3 — Latest version with new Infrared fuze. Delayed eight years from 1994 to 2002.
