Britain commissioned the last ship, HMS Spey (P234), built as River-class Batch 2.

HMS Spey was accepted into the Royal Navy at a ceremony at Portsmouth Naval Base on 7 January 2021. The platform is the fifth and final River-Class Batch 2 ship ordered.

All the Batch 2 ships of the class (Forth, Medway, Trent, Tamar and Spey) were built by BAE Systems in Glasgow.

There are differences in capability and operational capability between the Batch 1 River-class ships built and the Batch 2 ships. The maximum speed of patrol vessels is 44km/h and the displacement is 2,000 tons.  There is a Kelvin Hughes SharpEye integrated radar system for navigation on platforms, a Terma Scanter 4100 2D radar for air and land observation, and a BAE CMS-1 Combat Management System.

HMS Spey will be operationalised for piracy, trafficking and counterterrorism, as well as maritime defence missions.
