Global Firepower (GFP) continues to provide its unique analytical display of data concerning modern military powers. Over 125 powers are considered in the ranking which allows for a broad spectrum of comparisons to be achieved concerning relative military strengths.
The GFP ranking is based largely on each nation's potential conventional war-making capability across land, sea and air. The final ranking incorporates values related to resources, finances and geography and over 50 different factors make up the final GFP ranking, delivering the "PowerIndex" value with bonuses and penalties applied where appropriate. Updates to the list are attempted annually or when new information / corrections warrant them.
