The transferred frigates would remain useful after exhausting their most advanced ammunition because they would still have their guns and radar. Limbo is treated as a development of depth-charge technology that wartime Britain already understood. Taking sample mortars ashore and examining them is proposed as a route to producing replacements. Sonar, the 4.5-inch gun and some radar equipment are also considered plausible candidates for reproduction. Confidence is much lower for Sea Cat, so modern ships would not automatically provide a renewable stock of every weapon they carried.

Which Leander systems could wartime Britain reproduce?
Guns, mortars and some sensors might be reproduced by wartime industry, while guided missiles would be harder to replace.
