Satellite images of 21 October, analysed by Radio Liberty and reported by Ukrainska Pravda, show at least 33 air-defence positions built around the Alabuga special economic zone in Tatarstan since spring1. They include towers for Pantsir and Tor short-range air-defence systems and anti-drone nets over workshops. Dnipro Osint, a Ukrainian open-source imagery group, estimates 42,000 square metres of underground space at the site, and images from late August showed at least ten new workshops2.
Alabuga houses a factory for the Geran, Russia's descendant of Iran's Shahed attack drone; Russia also flies jet-powered versions, the Geran-4 and Geran-5. In August Ukraine's military intelligence agency (HUR) said Russia had no turbojet of its own and relied on Chinese engines for the jet Gerans3. Militarnyi, a Ukrainian military news site, reported in August that the Geran-5's Chinese engine produces 2,000 newtons of thrust4, five times the turbojet threshold in China's new export-licence rule. Jet Gerans made up about half of Russia's nightly launches at Ukraine on the nights to 20-22 October.
