hey Was wondering. http://en.wikipedia.org/wiki/Aircraft_carrier 1) Does USA really have 12 4.5 billion USD Carriers ? or are some from the cold war ? Are Cold war carriers of any use ? (like to carry helicopters) ? 2) Does france really have only 1 aircraft carrier now ? That seems small , one error and no more french carriers. 3) Which are the top 5 carriers in the world at the moment, and to which country they were built / belong to ? 4) Between all the new Carriers developments in the world , which are making the best ? Probably USA first , but then which countries ?
