5 Fighter Jets With The Highest Top Speeds In Service Today

Many of the fastest fighter jets in service today are from the Cold War era and remain critical tools in modern air forces, where top speeds exceeding Mach 2 still shape interception doctrine, deterrence strategy, and rapid-response capability. Aircraft designed in the 1970s, such as the MiG-31 (Mach 2.83) and F-15 (Mach 2.5), continue to fly in 2026 because their speed allows them to cover vast distances quickly, whether over Russia’s Arctic frontiers or US-controlled airspace. Drawing on verified data and technical specifications from manufacturers and previous Simple Flying analyses, we will explore why raw speed still matters.
