Somewhat of a replacement for the Mistral-class that Russia (with some controversy even in making the order in the first place) never managed to get from France several years ago. A 40,000 ton Universal Amphibious Assault Ship with the ability to carry helicopters, armored vehicles, air defense systems and several hundred naval infantrymen.
Interfax said:As Interfax reported, in July 2020, the first two ships of Project 23900, developed as an alternative to the French Mistral helicopter carriers, were laid down at the Zaliv plant in Crimea. Universal amphibious assault ships (UDC) are designed to receive, transport and disembark amphibious assault forces using landing boats and helicopters. An industry source told Interfax that these ships could go to the Pacific Fleet. "The decision will be made by the Ministry of Defense, based on the assessment of the balance of forces at sea," the source said.
