TAS can be put on any ship including a fishing trawler with a module sonar sweet, so not particular to OHPs, but point taken. However, taiwanese coord op ASW is more likely to be with fixed wing assets than organic helos.
I still think fast, ASUW focused corvettes would be a better fit.
I spent 3 wks in the North Pacific on an OHP as a Midshipman - I’ve never puked more in my life - spent a lot of time hanging from the hand cable strung across the bridge. I went into tactical naval aviation where I could handle the motion :-)
Ha - I loved that cable on the frigate and YPs at boat school - when everyone else was puking their guts out I’d be hanging with my feet off the deck grinning ear to ear. The 2nd CO I had on the RMD had it taken down :(
I’m with you though - I think a couple hundred 5 man ships equipped with harpoon equivalents would be a deadly combination against whatever came their way. That and lots and lots of air power and shore missle batteries.
