We have deployed cutters to the Western Pacific for months at a time, and PATFORSWA kept its 110s operating out of Bahrain for years, but the Royal Navy seems to be doing something different and I believe remarkable.
Naval News reports they are sending a pair of River Batch II class ships, HMS Tamar and HMS Spey, well beyond the Suez. It sounds all very 18th Century Star Trek, “Our Five Year Mission, Proceed into the Indian and Pacific Oceans and act in the Queen’s Interests.” (No, not a real quote.)
If these ships were in the US Coast Guard we would see them as MECs. They are slightly larger and faster than the 270s, but are not as well equipped in some respects. They are armed only with a 30mm gun and no helicopter hangar. I don’t believe they have any ESM/ECM. Their crew is also considerably smaller, smaller in fact than that of a 210. (I have seen various numbers for the crew size, 34 in the infographic above, 58 in Wikipedia, 46 as reported below, but all well below the 75 common on a 210 or the 100 typical of a 270.)
“Each ship is crewed by 46 sailors, with half the crew trading places with shipmates from the UK every few weeks.”
The Royal Navy actually has considerable experience keeping OPVs deployed for long periods with austere support.
We might even see one of these helping with drug interdiction in the Eastern Pacific, more likely they will be countering piracy and drug or arms trafficing in the Indian Ocean or capacity building in East Africa or SE Asia. Maybe we could make a multi-national Freedom of Navigation transit of the Taiwan Strait.
