Interwar planners expected that British forces in the Far East might begin a war locally outnumbered and without immediate support. A submarine could wait at one point in a channel while others covered successive positions instead of trying to chase a faster fleet. Their attacks could damage or split the approaching force before the main fleet action. Geography and planned positioning therefore supported the T-class requirement for a powerful first salvo.
