ORIGINAL: jufinace20 Hi, Having embarked on small tests to assess (A)SSM effectiveness I came across the following issue. Having a pair of Entendards attacking a lone HMS Sheffield (1982) I was baffled by: * Four SAMs guided by two directors \t * I assumed only one missile could be guided at any given time, may be I am wrong... * The SAMs being able to kill sea skimming Exocets at 18m above water \t * Having followed the news, and technical discussion at the time or after ther SeaDart was not considered effective against sea skimming missiles. I cannot remember any Exocet kill credited to the SeaDart. Moreover the difference between the HMS Sheffield, and the HMS Conventry attacks was the presence now of a Boxer class frigate to cope with the Exocet menace. In another test scenario a pair uk FFGs (a Boxer & a Duke) between them trash a OSCAR II salvo of Shipwrecks. May be this is credible, but it is not in pair with the performance of AAMs. The latter seeming much more plausible as technology is bound to fail from time to time. Thanks, Thanks for posting the save. On your questions: 1) In pure-SARH systems there is no limit to the number of weapons that can be guided to a target being illuminated. You can have one, ten or one hundred missiles in the air. The grave handicap is the limited number of _targets_ having weapons enroute to them. A Type 42 and e.g. a Burke DDG may both have 10 missiles each in the air, but the Type 42 will be guiding them towards 2 targets max while the Burke may guide each one of them to a separate target. In the late-80s/early-90s the Sea Dart system was improved via the ADIMP program, gaining abilities similar (though more limited) to Aegis/SM-2. With ADIMP, only terminal SARH illumination is necessary (like SM-2) and up to eight missiles can be in mid-course guidance via datalinks. Like Aegis, this both increases the tactical range of the missile and also enables true multi-target engagement ability. This upgrade is included in the DB3000. 2) The Sea Dart was IIRC not sea-skimmer capable at the Falklands timeframe. This doesn't mean it absolutely cannot engage VLow targets, but it does mean the hit probability suffers greatly. This modification should be listed on the message log. Thanks.
