Petrozavodsk Air Base (Besovets)

Petrozavodsk Airport (IATA: PES, ICAO: ULPB), formerly known as Besovets and Petrozavodsk-2, is a joint civil-military airfield in the Republic of Karelia, Russia, situated 12 km northwest of Petrozavodsk at Besovets in the Shuya Rural Settlement. The civil side handles small airliners, with limited apron space and twelve parking stands.

The airfield was used as an interceptor base during the Soviet period. Sukhoi Su-15 aircraft operated from Besovets in the 1960s or 1970s. In the 1970s the 991st Fighter Aviation Regiment (991 IAP) was stationed there with Mikoyan-Gurevich MiG-25 'Foxbat' interceptors. In 1992–93 the 159th Guards Fighter Aviation Regiment (159 GvIAP) relocated to Besovets from Poland, leaving the 4th Air Army.

The 159th Guards Fighter Aviation Regiment remains the resident unit and has operated the Sukhoi Su-35S since at least 2019. The regiment is subordinate to the 105th Guards Mixed Aviation Division of the 6th Air and Air Defence Forces Army.

In November 2019, specialists of the Military-Construction Complex of the Russian Ministry of Defence completed reconstruction of the runway's artificial surface.
