Clearly right for the UK. It was designed to meet their requirements and budget. So? While I am a solid big deck CV guy it seems like a lot of folks here think the CV will, or should be, around forever. It won't. Time was when the UK was a big deck CV player. Not now. So when will the US be forced to move away from the big multi-purpose CV, and what will replace it? For a bunch of smart well informed and experienced minds, an aweful lot of what I see here is not forward thinking. Things will change. Dismissing folks that make alternative arguements when we have the luxury to do so is short sighted.
The problem with Polmar and others is that I would argue the whole CVL debate is not forward thinking but very old thinking, more than 50 years old now. This is only the latest in a long line of almost identical arguments going back to Zumwalt's 'Sea Control Ship' concept that had CVL's equipped a handful of VSTOL fighters and helos. They would make great escort ships but crappy force projection platforms, which is what most more modern commentators seem to envision their more 'modern' proposals being.
I think Navy leadership, rightfully so, has seen these CVL-ish proposals as a dark horse that would cut the budget and take an even more proportional hit in capability for a ship that would be doing nothing more than looking for a mission. They would be more difficult to utilize in a 'peer-level' fight due to their reduced capability and flexibility. For just 20% of the cost you could get just 5% of the capability! I have no idea of the actual return on investment but when you take away a CVN's greater flexibility and, I dare say, sustainability in a wartime scenario you are left with a platform that doesn't give you anywhere near the bang for the buck.
As for the UK, you have to go back over 40 years to when they last had 'big deck' CV's and even then theirs were only half the size of US ones at their biggest. If a country is able to afford it building a 'big deck' carrier seems to be the desire of every blue water Navy, from France to Russia and China.
Another quibble that I have is on a more minor detail that he dismisses with only two, maybe 3, sentences:
Furthermore, there have been studies of the feasibility of operating the Osprey in the antisubmarine and airborne early warning (AEW) roles. The British, Chinese, and Russian navies have flown helicopters in the AEW role with success.
First off I am not sure how he got his info on how successful the Russians and Chinese have been with their AEW helos but even in the best case their capability is far less than a conventional aircraft. Secondly folks just seem to airily dismiss the fact that we would have to design, develop, fund and field a new platform, good luck trying to hang it on an H-60, with a new radar to boot to equip the proposed CVL's with an AEW capability. I'm sure that'll go well.
I'm not against new arguments or bold ideas but I am against dumb ones, while certainly not even close to the dumbest idea I have seen I think the capability and flexibility of a CVN is hard to beat even with the large cost.
