Restraint after a Russian warship fired at a yacht

What did Britain's response to a Russian warship firing at a British yacht show about available naval forces?

British assets were watching and restraint preserved the diplomatic advantage, but inadequate maintenance infrastructure limited the visible force available nearby.

British vessels were watching the Russian warship even though the response did not become a visible confrontation. Because the target was an unarmed yacht, restraint left Russia unable to claim that Britain had provoked an exchange. More British units in the area would still have been preferable. Repeated surges and inadequate maintenance infrastructure reduce the number of ships that can be generated when such an incident occurs.
