Russia has begun building shelters for strategic aircraft used to strike Ukraine at Engels-2 air base in Russia’s Saratov Oblast.

In early September 2026, the OSINT community AviVector reported that satellite imagery showed construction beginning on the first of 16 planned shelters.

The shelters are being built as the range and intensity of Ukrainian strikes increase. On the night of Aug. 28, Ukraine’s Defense Forces struck a Tu-95MS strategic bomber at Engels airfield, along with an ammunition depot and a fuel and lubricants depot. The Ukrainian drones traveled 800 km to reach the target, Ukraine’s SBU Security Service said.
