"The Russian armed forces attacked the village of Velika Pisarevka in the Sumy region with a heavy ODAB-1500 aerial bomb. The military analyst of the German newspaper BILD, Julian Röpke, states that after the impact of the ODAB-1500, a cloud of smoke with a height of 1 km rose into the sky.
The volume detonating aerial bomb (UDAB) is a Soviet-era thermobaric projectile that releases an incendiary liquid in the form of an aerosol about 10 meters before striking the target and igniting it. This is called a volume explosion. Such ammunition has a greater striking power than the classic ammunition.
Previously, the Russian armed forces used ODAB, but with a smaller mass: from 170 to 500 kg. Röpke calls the use of a 1.5-ton bomb in the village "a new bottom in Russia's war against Ukrainian cities".
