What could a Sea Slug-sized missile achieve if built with Sea Dart-era technology?
Short answerIt would be a very large, Talos-like air-defense missile with excessive destructive power and a credible secondary anti-ship effect.
NotesSea Dart-era technology in a Seaslug-sized missile is compared with a more advanced British version of RIM-8 Talos. Air defense would remain its primary purpose. A surface ship could also be attacked, and a direct hit would have severe effects on either kind of target. The comparison includes Talos's nuclear-warhead option, although even a conventional hit is described as highly destructive. No specific range or performance figures are offered for the hypothetical British weapon.
