It's not as if the concept of smaller, simpler, vessels for certain uses is exactly new to the RN:
Peacock class - Wikipedia, the free encyclopedia
700 odd tons, fully air conditioned for working in tropical climates, "capable of remaining at sea during typhoons" (whatever that means). As a crab I don't know how successful they were, but as a concept?
Maybe something slightly (not hugely) bigger next time, able to carry a Lynx size helo, and with a few more close in weapons of 20-30mm size (anti piracy/drug smuggling)? Just a thought....
It would appear the Philippine Navy agreed with me, as they upgraded their ex-RN Peacocks with a 25mm cannon and some smaller caliber weapons.
