34th Mixed Aviation Division
Identity
This record matches the Baltic Fleet naval aviation formation spread across Kaliningrad Oblast rather than a single installation. FOI assessed the 34th Mixed/Composite Aviation Division as having replaced the former 72nd Aviation Base in 2019, with principal combat elements at Chernyakhovsk, Chkalovsk, and Donskoye; the supplied placemarks are consistent with that disposition.

Chernyakhovsk
The division’s fixed-wing strike element is the 4th Guards regiment at Chernyakhovsk. Open sources reviewed confirm Su-24M and Su-30SM/SM2 activity there, and Baltic Fleet reporting in 2025 described joint Su-24M and Su-30SM2 training against maritime and land targets, consistent with a naval strike and coastal-support mission; the exact aircraft counts in the placemark text were not independently verified from authoritative sources.

Chkalovsk
Chkalovsk has been the fighter node of the formation. FOI identified the 689th Guards Fighter Aviation Regiment there with Su-27 fighters, UAV support, and a transport/VIP element, maintaining quick-reaction alert for air-policing and reconnaissance tasks over the Baltic approaches. However, Russian state-media reporting in mid-2024 said the 689th regiment was removed from Baltic Fleet naval aviation and subordinated to the 6th Air and Air Defence Army, so this hierarchy may now be partly outdated.

Donskoye
Donskoye remains the helicopter base associated with this aviation grouping. FOI identified a helicopter regiment there with Ka-27PS search-and-rescue, Ka-27PL/M anti-submarine, Ka-29 naval transport, plus Mi-8 and Mi-24 helicopters; later Baltic Fleet reporting described Ka-27 and Ka-27M anti-submarine drills and routine flights from Donskoye, reinforcing its ASW, SAR, and fleet-support role.

Khrabrovo
Khrabrovo is a joint-use airfield publicly identified by Kaliningrad city authorities and a 2024 analytical map as the home of the Baltic Fleet’s 398th Independent Transport Squadron. The official local-government source specifically lists An-24 and An-26 aircraft there; broader current fleet details in the placemark text were not authoritatively confirmed in the sources reviewed. As a separate transport node inside the Kaliningrad semi-exclave, Khrabrovo supports regional movement and sustainment for the wider Baltic Fleet aviation grouping.
