Bulgaria boosts defense budget to $4B by 2031, modernizing forces with F-16s and new naval frigates for NATO readiness.

Bulgaria is increasing its defense budget from $2.9 billion in 2026 to $4 billion by 2031, driven by a 6.5% annual growth rate. This boost supports modernization efforts focused on NATO interoperability, including acquiring F-16 fighter jets to replace older MiG-29s, upgrading land forces with Stryker vehicles and enhanced tanks, and commissioning new naval frigates. These moves respond to heightened geopolitical tensions, notably the Russian invasion of Ukraine, and aim to strengthen Bulgaria's military capabilities through 2035. The defense market also offers investment opportunities in aircraft, missile systems, and naval vessels, supported by detailed forecasts and data analytics tools.
