The overseas patrol squadron grew out of the Fishery Protection Squadron and includes River-class ships such as HMS Tamar and HMS Spey. Their Indo-Pacific deployments use the British support facility in Singapore and sustain a presence around important commercial routes. The argument connects that presence with participation in decisions around trade chokepoints. Batch 2 Rivers carry a 30 mm cannon and Batch 1 ships a 20 mm cannon, with machine guns providing additional armament. Small UAVs are a possible addition if funding supports their sustained operation. The ships' patrol role and light armament limit the capability supplied by that presence.

Global OPV presence has diplomatic value and hard limits
River-class ships keep Britain engaged around major trade routes, but their light armament limits what that presence can accomplish in a crisis.
