The United States fields the largest modern carrier force in the world and very few nations field more than one. For the purposes of the GFP ranking, Helicopter Carriers are now included in this listing due to their growing popularity worldwide. Landlocked nations are not penalized for the lack of a standing naval force. Aircraft carriers currently under construction (as of 2015) are excluded.
