Was Sea Dart on the Invincible-class through-deck cruisers useful or a waste of space?
Short answerUseful; it made the ships contributors to fleet air defense, though a larger design with both Sea Dart and Sea Wolf would have been better protected.
NotesSea Dart is judged useful aboard the Invincible-class through-deck cruisers. The preferred alternative in the answer is a slightly larger ship carrying Sea Wolf as well. The combination would make the carrier a stronger contributor to the formation's air defense. This is a proposed improvement to the design, while the existing Sea Dart installation is still considered worthwhile.
