Yeah, like I said, something the Rivers should be able to do.I rather suspect the intent with T32 is for surveillance in offshore areas in such things as ASW; and possibly control of minimum or un manned weapons platforms as for the USN concept. They really need to invest in a smallish platform with only self defence armament and the capacity to go inshore for the MCM task, a bit like the RAN is looking to do with a similar concept and using the follow on 8 Arafuras.
The RN has -
3 Batch 1 River class OPVs. 80m, 1700t, 20 knots, 20mm gun & GPMGs.
5 Batch 2 River class OPVs. 90m, 2000t, 24 knots, helideck, 30mm gun, miniguns & GPMGs.
Both have cranes & an open deck aft for carriage of additional equipment.
The Batch 2s are more military in construction standards & CMS, I understand, & thus more suitable for such a role outside home waters. They're also 15 to 18 years younger, commissioned April 2018 to June 2021. Since we're already sending them off to remote places it seems a reasonable addition to their capabilities, & of course, autonomous mine hunters don't need to be constantly carried.
