The Soviet Union's response to the Atomic Annie gun from the US is the 2B1 "Oka." They opted to create their own version because they were lagging behind in technology. At the height of the Cold War, it was developed. On August 20, 2018, a member of the Ukrainian army checks his phone as he waits to lean against a tank for a parade practice in Kyiv before the country's independence day celebrations on August 24. The parade on August 24 will feature 4,500 service members and 250 pieces of military hardware, including the newest ones made in Ukraine. According to Interesting Engineering, the 2B1 "Oka" is a transportable, heavy artillery piece with a huge caliber that is meant to launch nuclear-tipped munitions. It took its cue from the "Atomic Annie"-named initial testing of the M65 gun. Soviet Union’s Atomic Mobile Mortar ‘2B1 Oka’

The Council of Ministers of the Soviet Union devised a covert plan in November 1995 to produce their own version of "Atomic Annie," with factories creating two new atomic munition delivery systems in various cities. The "Condensator-2P" and the "Oka 2B1 mortar" were them. The "Oka" was created as a result of a Soviet engineering initiative to create a mortar with a 1,653-pound nuclear projectile that could travel up to two kilometers. Additionally, it was made to be dependable, strong, and fire at a respectable rate. It is also portable, which is essential for this kind of machinery. Soviet Union’s Atomic Mobile Mortar ‘2B1 Oka’

The Kirov Company created the chassis by altering already-existing technology to complete the task. The Oka mortar was built on the base of the IS-5, the most powerful Soviet tank. A V-12-6B diesel engine with 750 horsepower was installed in the chassis. However, due to the weight of the 55-ton gun that had to be affixed to it, the engine could only travel around 125 miles. Furthermore, it was planned for the chassis to be typical for the "Condenser -2P" and "Oka" mortars. Then, they attached the 65.5-foot-long, 420-mm gun to it with a kickback dampener that was built into the main chassis to manage recoil.
