The Royal Navy is looking at how they might increase the lethality of their new River Class Batch II Offshore Patrol Vessels. Save the Royal Navy looks at how they might be upgraded. “Save the Royal Navy” describes itself as “an online campaign but not an organisation as such,” so not an official voice of the Royal Navy.
These are effectively the UK’s WMECs. They do fisheries, SAR, and drug enforcement, but they are looking to use them for a bit more. They have the three River class Batch I OPVs to do fisheries around the home turf, so they plan to use most of these in the overseas territories or providing presence in distant theaters of operation. One is currently deployed to the South Atlantic operating out of the Falklands and a second is tasked with operations upholding UK interests in the Caribbean, Gulf of Mexico, and Western North Atlantic. It is likely one will go to Gibraltar and another to the SW Asia/Persian Gulf/Indian Ocean Area.
Compared to our own WMECs, the River Class Batch IIs are bigger and faster than the Bear class.
- 2000 tons vs 1800 tons
- 297′ (90.5 meters) vs 270′
- 24 knots vs 19.5 knots
But they are equipped more like a 210. They have no helicopter hangar and only a single 30mm gun in an optionally manned remote weapon station while the Bear class has a 76mm gun and radar fire control system and they have nothing like the Bear class’s SLQ-32 and decoy systems.
“Save the Royal Navy” considers upgrade packages that were labeled, in order of increasing complexity, “OPV Plus”, “OPV Max”, and “Corvette”.
“OPV Plus” includes a container based rotary wing UAS like the Schiebel Camcopter S100, two 30mm guns, a BAE Bofors 40mm/70 Mk4 with a possible fire control upgrades, and Long Range Acoustic Device (LRAD).
“OPV Max” includes a collapsible hanger for an Agusta/Westland AW-159 Wildcat helicopter, two 30mm guns, added Martlet LMM (Light Multirole Missile) to the 30mm mounts, and a BAE Bofors 57mm Mk110 and associated fire control system, but for some reason lost the LRAD.
“Corvette” traded the hangar for Anti-Ship Cruise Missiles (ASCM) and exchanged a RHIB for an armed Unmanned Surface Vessel. In addition to two 30mm guns with LMM Martlet missiles, and a BAE Bofors 57mm Mk110 and associated fire control system, it also adds an enlarged operations room (CIC), decoy launchers, and a multirole Artisan 3D radar.

The comments are cringeworthy. It seems anybody suggesting a more realistic stance is being down voted. Not the best site really. Probably does their cause more harm than good.
The B2 Rivers are being forced on the RN.
Replace the current gun with a 57mm. Maybe not perfect at anything but with guided rounds, credible at anything.
Improve the aviation facilities.
There. You then have an OPV that is still an OPV but with bigger teeth.
Trying to turn the thing into an FAC or Corvette will greatly impact the ability to use the ship as an OPV.
Aviation helps in both law enforcement and military scenarios.
It was the only fault with the B1’s, no flight deck.
I’d say for the British is to ditch the 30 mm and bring in the 57 MM with Guided rounds. Add two 30 MM Guns or 2 M2’s. At the same time, enhance Aviation facilities for helicopters and UAVs.
