India recently commissioned INS Saryu, the first of a new class of Offshore Patrol Vessels (five photos), that are in many respects similar to the planned Offshore Patrol Cutters. I don’t think anyone is considering these as contenders for the OPC contract, but with similar mission profiles, they do show what the OPC might look like. From the Wikipedia Description:

The 2,300 ton displacement is probably the light displacement. Full load is probably more. The beam is essentially the same as the 378s, so the helicopter facilities look reasonable, although I hate to see them all the way aft, where they are most effected my pitching.

I’m hoping for a more sophisticated hybrid or integrated diesel electric powerplant on the OPC, but the two diesels on Saryu providing almost 21,000 SHP are certainly adequate, meeting the OPC’s objective speed of 25 knots.

Crew size is very similar, with a total of 110 compared with the OPCs’ projected Manpower Estimate of 104 total (15 officers, 9 E-7 and above, and 80 E-6 and below) plus up to 12 attached personnel. (Another source indicates Saryu will have a crew of 16 officers and 102 enlisted.)

Range is a little less at 6,000 nmi compared with 7,500 minimum for the OPC, but it is measured at a higher speed–16 vice 14 for the OPC. It is likely the Saryu would also have a longer range at lower speeds.

The armament is also similar, only a bit heavy on the Indian vessel compared to the 57mm Mk 110, single 25mm Mk38mod2 and two remotely controlled .50 cal projected for the OPC.

A little surprising, that these ships are being built for the Indian Navy, instead of the Coast Guard, which in India is part of the Navy, but there is also, reportedly, an outstanding contract for six similar ships for the Indian Coast Guard.
