Further to my comments to Hambo, my aim is to have enough high end ships so we can truly go anywhere and also to have a global presence to do all the day to day stuff that we don't currently do but should.Been down this route before with the Type 21's though - light yacht built 2500 tonners criticised as being underarmed from the moment they entered service, did a fine job for the work required but when called to arms in the Falklands, served as little more than floating targets - no decent air defence, no scope for upgrades and not very survivable.
Thing is, if you swap the 5 GP type 26's out for say, 10 of these puppies, that's pretty much the MHPC buy soaked up. Or do you want to fund that too and have twenty odd not very combat worthy OPV's flitting around ?
I think you're gutting the RN to fulfil an imaginary requirement. There's no need whatsoever for us to be enforcing Pax Brittanica, the 21st century happened and we're living in it. Why are we pretending to be the global policeman when we're so greatly reduced in standing?
Strip out the GP type 26's and you're pulling the RN in two opposite directions leaving a very hollow middle.

The fact is that technology now allows for minor war vessels to have real bite through the addition of helicopters, unmanned vehicles and modular weapons. The value of having a middle ground vessel is much less than it used to be as long as you low end can support these capabilities. So, in my view you need a high end ship with the size for sensor fit and survivability and a low end ship with long legs.
Also, functions such as survey and MCM are important for task groups too, so these light frigates will be part of any conflict just protected by the big boys.
