Seasprite to Sea King: The Royal Canadian Navy’s Ship-borne Antisubmarine Helicopter Capability ne of the better-known achievements of the post-war Royal Canadian Navy (RCN) is the Ointegration of the large Sikorsky Sea King antisubmarine helicopter into small surface escorts. Of this, “radical and entirely Canadian development,” Tony German writes that it was, “hugely admired” by other navies and that, “[a]fter eight years’ development Canada’s navy on its own brought a whole new dimension in anti-submarine [sic] warfare to the navies of the world,”1 yet the remainder of his publication, The Sea Is at Our Gates, pays little deference to this accomplishment.
