The River class is best measured by what it can sustain rather than by headline armament. Batch 2 vessels are described as capable of about 25 knots and 35 days at sea, enough to spend roughly a month on maritime-security patrol. Their extra accommodation can embark up to 50 Royal Marines or other personnel, while fast launch and recovery of raiding boats widens boarding, reinforcement, and engagement options. Endurance, people, aviation access, and boats give an offshore patrol vessel substantial value across everyday missions without turning it into a frigate.
