The United States fields the largest modern carrier force in the world - Italy and Spain are the only nations to field more than one aircraft carrier. For the purposes of the GFP ranking, Helicopter Carriers are not included as they lack the overall capabilities inherent in "flat-top" carriers when launching farther-reaching fixed-wing aircraft. Landlocked nations are not penalized for the lack of a standing naval force. Aircraft carriers currently under construction (as of 2014) are excluded.
