The Royal Navy is sending two of their River Class Batch II offshore patrol vessels to serve long term in the Indo-Pacific.
Interesting to see camouflage applied to these ships. I also note they are commanded by Lt. Commanders. The crews on these ships are about half what we would expect on a comparable Coast Guard Cutter. In all probability crews will be rotated as was done with the crew of the earlier River class OPV, HMS Clyde, stationed in the Falklands.
The video makes it sound like these will both be going to the Pacific, with no British bases in the area, but Indo-Pacific includes the Indian Ocean as well and the British have a base in Bahrain and while it is also a US base, Diego Garcia is a British possession. Still it sounds like they will be making the rounds showing the flag.
