The finalized Global Firepower ranking relies on over 50 factors to determine a given nation's PowerIndex ('PwrIndx') score. Our formula allows smaller, though more technologically-advanced, nations to compete with larger, lesser-developed ones. Modifiers (in the form of bonuses and penalties) are added to further refine the list. Some items to observe in regards to the finalized ranking:
+ Ranking does not simply rely on the total number of weapons available to any one country but rather focuses on weapon diversity within the number totals to provide a better balance of firepower available (i.e. fielding 100 minesweepers does not equal the strategic and tactical value of fielding 10 aircraft carriers).
+ Nuclear stockpiles are NOT taken into account but recognized / suspected nuclear powers receive a bonus.
+ Geographical factors, logistical flexibility, natural resources and local industry influence the final ranking.
+ Available manpower is a key consideration; nations with large populations tend to rank higher.
+ Land-locked nations are NOT penalized for lack of a navy; naval powers ARE penalized for lack of diversity in available assets.
+ NATO allies receive a slight bonus due to the theoretical sharing of resources.
+ Current political / military leadership is NOT taken into account.
For 2017 there are a total of 132 countries included in the GFP database.
