Why wouldnt it be serious? Note that the COST is max 9000 tons to make conversions an option

Carriers are becoming the ultimate WW status symbol. Everybody's got to have one or two or twelve, regardless of whether or not it'll actually work in their fleet's strategy. I think a Persian carrier will be the best way for Persia to waste their tonnage in the fastest possible way. Hence why I dismissed any notion of a Bulgarian CVL. No need, and I'm not going to waste my budget.

That has nothing to do whether the request is serious or not and the Indian Ocean is slightly bigger than the Black Sea

Buy one of the sackets harbour class CV's, it'll be cheaper and have most of the bugs already worked out.

Who is Sacket?

The Sacket's Harbor is one of the American light CVLs built on an Omahaha-class cruiser hull.

In that case, Ireland is definitely justified in building a light carrier, wot wot? After all, I might have to use her to hunt submarines attacking convoys on the Western Approaches, or something.

Ah, so now i only have to find a Omahaha(?) class cruiser

It's a midwestern US joke, don't worry about it.

That might be an idea if can get it second hand

Doubtful, IMHO. There's probably a waiting list already among the US's allies. (Mexico, cough cough?)

U.S.S. Wolverine would not be a very usefull carrier, unless the Persians plan to use the ship as the Americans did, as a breif landing point for land aircraft.

Turkey's neighbour has carriers, yet Turkey doesn't, she feels she doesn't need them. I have to agree that theres no real need for Persia to have one either given the fact that land based aircraft can easily cover the Persian Gulf and the Gulf of Oman.

It would be interesting to see it take on a typhoon or two!!

Useful, but not ideal, for the purpose for which they were created, a real "niche" design.

Other than Lake Superior, which can be a real beast, yes they handled well enough.

STAY AWAY FROM MY CARRIERS!!!

Australia thinks its not Persia talking but rather India. After all another carrier would be mighty useful if operating with the Indian Navy...
