Ivan Rogov-class amphibious assault ship

The Ivan Rogov (also known as the Project 23900) is the newest class of Russian amphibious assault ships intended as a replacement for the French Mistral class, two of which were ordered by Russia in 2011, but that France refused to deliver in September 2014 due to the Russo-Ukrainian War. A contract was signed on 22 May 2020 for the construction of two Project 23900 ships with a displacement of 40,000 tons. The construction is led by JSC Zelenodolsk Design Bureau, which is a part of JSC Ak Bars Shipbuilding Corporation. Previously, the Lavina, and Priboy designs were proposed by the Nevskoe Design Bureau and Krylov State Research Center as the replacement for Mistrals. Project 23900 is also a successor class to the unrealized Soviet Project 11780 program.
