Could a Leander-sized ship carry Seaslug, and how would it be arranged?
Short answerYes, probably aft, with no hangar and little forward armament beyond possible 40 mm guns.
NotesA Leander-sized ship could carry Seaslug with severe compromises. The suggested system would sit aft. There would probably be no substantial forward gun armament, though a few 40 mm Bofors might fit. A hangar would also be sacrificed. The missile system would dominate the ship's capacity.
