Currently, the strategic TU-22M3 bombers take flight from southern Russia at Modzok airfield; however, this newly signed military agreement with Iran will allow Russia to reduce flight time by 60%, saving the Kremlin both money and improving airstrike effectiveness, according to Al-Masdar News.
The distance of these flights equal roughly 2,150km to reach a target near Palmyra. In comparison, the Hamedan Air Base in Iran is roughly 900km from Palmyra.
