ISW estimates how many aircraft Russia lost due to Ukrainian drone attacks on airfields

ISW writes about this.

The geolocation footage shows explosions and the activation of Russian air defense near all air bases except one near Yeysk. Therefore, analysts have not yet been able to confirm for certain the damage to aircraft or infrastructure at Russian airbases.

Satellite imagery from April 4 shows that Engels airbase had three Tu-160 heavy strategic bombers, five Tu-95 strategic bombers, an Il-76 transport aircraft, and a Tu-22 bomber. Instead, the Yeysk airbase had ten L-39 training and combat aircraft, five An-26 transport aircraft, an An-74 transport aircraft, an An-12 transport aircraft, four Su-27 fixed-winged aircraft, four Su-25 fixed-wing aircraft, one Su-30 fixed-wing aircraft, and several Ka-52 and Mi-8 helicopters. Morozovsk airfield was home to 29 fixed-wing aircraft, primarily Su-34s.

"ISW continues to assess that Ukrainian strikes against targets within Russia are a necessary component of Ukraine’s campaign to degrade industries that support the Russian war effort and military capabilities deployed in the Russian rear through asymmetric means," the analysts said.

• On the night of April 4-5, Ukrainian drones attacked Russian military airfields in Yeysk, Kursk, Engels, and the Morozovsk air base in the Rostov region of Russia. The attack damaged a total of 19 aircraft, including 3 Tu-95MS strategic bombers.
