Named after the historical figure Ivan Mazepa, the Ukrainian Cossack leader who famously opposed Peter the Great, the ship was officially laid down on 7 September 2021 and launched on 2 October 2022.

In the 1990s, the Ukrainian Navy primarily comprised of naval vessels inherited from the Soviet Black Sea Fleet and Soviet Border Troops. However, economic hardship after Ukraine's independence led to many of these vessels being scrapped or sold.

Following the 2014 revolution, relations between Ukraine and Russia soured, culminating in the annexation of Crimea by Russia. This resulted in most of the Ukrainian Navy, including major ships like the corvettes Lutsk and Ternopil, being seized.

The drastic reduction in the navy's combat capabilities necessitated the acquisition of new ships. A memorandum was subsequently signed with Turkey, leading to the purchase of Baykar Bayraktar TB2 attack drones and the construction of two corvettes, with an option for two more.
