August 15 strikes set off a massive fire at Russia's Savasleyka airbase in Nizhny Novgorod Oblast, a site Ukrainian officials said they successfully hit.
ISW said the attack reflects a shift toward systematically striking Russian ballistic-missile launch infrastructure as Ukraine copes with shortages of air- and missile-defense interceptors.
Savasleyka hosts a branch of Russia's 4th State Center for Aviation Personnel Training and Military Tests and bases MiG-31K jets armed with Kinzhal aeroballistic missiles.
The airfield, about 680 kilometers from Ukraine's border, has been hit repeatedly before, including in August 2024 and again in April and June 2025.
