As Third Sea Lord, Admiral Reginald Henderson faced the problem of sustaining a fleet that could protect a global maritime system under peacetime political constraints. Sloops could perform future convoy escort while also serving as station ships, yachts, survey vessels, training commands, minesweepers, and communications links. Their visible presence also mattered, allowing the Royal Navy to maintain relationships and collect information in places where sending a cruiser or battleship would be impractical. These roles gave a practical doctrinal basis for continuing development. Henderson's tenure accounting for 58 of the 73 interwar orders makes the programme a sustained force-design choice rather than a handful of disconnected small-ship purchases.
