Fleet Modernity Score
4.1 / 5.0
Count-weighted average generation of the named fleet above, NOT raw aircraft count. This is exactly the fix for "600 obsolete jets vs. 300 modern ones": North Korea has more aircraft than most of its neighbors but a modernity score near 2.0 (nearly all Gen 2-3), while the US and Israel score near 4.5-5.0 despite smaller headline totals in some matchups.

Era reflects armor generation, not raw count — e.g. North Korea's tank fleet is numerically large but almost entirely Cold War-era T-55/T-62 derivatives, while a much smaller modern Advanced-era fleet (M1A2 Abrams, Leopard 2A7, K2 Black Panther class) typically outmatches it on paper.
