As the original poster in that thread said,

We’d have to spend a fortune on infrastructure (how much to rebuild a base for it?), the running costs would be vastly higher than for the QE class, & then there’s what we’ve already spent on CVF.

I can’t see how it wouldn’t end up far more expensive than buying both QE & PoW, both in the short & long term.

Agreed, it’s a bloody stupid idea and I can’t see how anyone could give it any credence at all.

Those Rum Rations postings look to be based on misinterpretations.

If Type 26 comes in at the same sort of price as FREMM – in the region of ~ £250 million then I would be happy but I read yesterday that the Type 26 will be closer to £500 million. However if they want to export the Type 26 it got to come in at the lower end. The cost of fitting phalanx across the board is more like the cost of three maybe four OPV’s (using the Spanish BAM as an example) than a couple of frigates – I still think that if the RN has the money to fit Phalanx across the board they would be better off buying the OPV’s than fitting the Phalanx.

Err aren’t the FREMMs supposed to come in at a price of half a billion Euros?

Making a few rapid counts:
4×2 = 8 Phalanx for the Bay class.
2×2 = 4 Phalanx for the Wave
2×4 = 8 Phalanx for the Fort class
6×2 = 12 Phalanx for the Type 45
(3×2= 6 Phalanx for CVF)

I thought CVF Carried 4 Phalanx mounts?

Though accquiring CVF and then losing amphib capability is so self defeating it sounds like something defence planners would do! 😮

It does sound like a particularly stupid idea.

Yes, a new Ocean has many advantages. My preference for a modified Juan Carlos is largely based on my feeling that it would be advantageous to have a third ship able to launch STOVL aircraft, as an emergency back-up.

Note that I’m not proposing the purchase of a third carrier disguised as an LPH or LHD, but an LPH or LHD* which can, in emergency, be used as a STOVL lily-pad. That’s all.

*I’m agnostic. I see more need for helicopter capacity than more docks, but it might not be worth messing around with the design to eliminate the dock.

I’ve stated the same thing on numerous occasions.

Other points in favour, it’s big, already exists and it’s not that expensive.

Yes, ridiculous isn’t it.

or with the economies of scale in our favour order a third QE…..

I can’t see this as anything but a non-starter, it will always be too expensive compared to Ocean.
