A Tiger Cub could protect a convoy by making an attack too costly for a stronger raider. Its aim would be to damage a battlecruiser enough for the next British ship to catch and defeat it. A raider expecting to win the immediate fight would still have to consider whether that victory ended its wider operation. This requirement helps explain the 9.2-inch battery: it provides a credible threat without the expense and weight of capital-ship guns.

A convoy escort can deter a stronger raider through damage
An escort does not have to defeat a battlecruiser alone if the damage it inflicts would leave the raider vulnerable to the next British warship.
