[not verified in body] Initially, the "Priboy" and "Lavina" helicopter carrier designs were first revealed in June 2015 during the "ARMY-2015" military-technical forum, as a replacement for the two undelivered Mistral-class vessels ordered by Russia in 2011 under a $1.3 billion contract.
[citation needed] However, due to the international sanctions against Russia, the French refused to proceed with the delivery and the deal was suspended in 2015.
[9][10] In June 2017, Vice President of the United Shipbuilding Corporation Igor Ponomarev said the "Priboy" helicopter carriers were implemented in Russia's New State Armament Programme for 2018–2025 and that the construction of the ships could be carried either by Severnaya Verf, Baltic Shipyard or Sevmash.
[17] On 28 February 2021, it was reported that the shipbuilders had begun to build the hulls of the two future amphibious assault ships.
Infrastructure facilities initially intended for the second Mistral-class vessel are being prepared in Sevastopol, scheduled to be ready by the time the ship is commissioned.
[17] On 14 December 2021, it was reported that the Project 23900 ships will be able to carry strike and reconnaissance drones, which will greatly enhance the helicopter carriers' combat capabilities.
[22][23] On 20 June 2024, it was reported that Ivan Rogov will be ready for factory and sea trials by the end of 2027, and should be delivered to the Russian Navy in Q3 2028.
