County cruisers in Far Eastern deterrence

Suffolk and other Counties served in the Far East as anti-raider ships and potential trade-interdiction forces. Several fast cruisers loose in the East and South China Seas could force Japan to spread naval and air resources across major commercial routes. The interwar decision should be judged without assuming the mature air power of 1945, which depended on later advances in aircraft, engines, weapons, navigation aids, and radar. In the Singapore concept, cruiser attacks on trade could force Japan to protect merchant shipping or moderate an offensive while a larger British fleet arrived. Mines, submarines, destroyers, smaller cruisers, and fast cruisers formed a layered deterrent. The strategy had weaknesses, yet it offered a plausible way to impose costs and buy time.
