the Black Sea Fleet significantly. Analysis undertaken by Micheal Peterson of the US Naval War College suggests that since the Russian seizure of Crimea, the modernization of Russian shore-based assets and of the Black Sea Fleet itself has assisted in re-establishing Russian military dominance in the region. Specifically Peterson argues: "Russian maritime dominance in the Black Sea is back. The shift was made possible by Moscow's 2014 seizure of Crimea and subsequent buildup of combat and maritime law enforcement capabilities in the region". Prior to the annexation of Crimea, divergent announcements were made concerning the future composition of the fleet. In June 2010, Russian Navy Commander-in-Chief Admiral Vladimir Vysotsky announced that Russia was reviewing plans for the naval modernization of the Black Sea Fleet. The plans include 15 new warships and submarines by 2020. These vessels were to partially replace the reported decommissioning of Kerch, (decommissioned in 2011 and sunk as a blockship in 2014), several large support ships, and a diesel-electric submarine. Also in 2010, Russian Navy Headquarters sources said that, by 2020, six frigates of the Project 22350 Admiral Gorshkov class, six submarines of Project 677 Lada class, two large landing ships of Project 11711 Ivan Gren class and four class-unspecified ships would be delivered. Due to the obsolescence of the Beriev Be-12 by 2015, they would be replaced with Il-38s. Sukhoi Su-24M aircraft were planned to be upgraded to Su-24M2 at the same time. Since the annexation of Crimea, the composition of the Black Sea Fleet has shifted to focus on the Improved Kilo-class submarines instead of the Lada, the s and at least three new classes of missile corvettes (the , and Buyan-M classes). The deployment of the Admiral Gorshkov-class frigate with the Black Sea Fleet was still anticipated, though in reduced numbers. The replacement of the Black Sea Fleet's Soviet-era missile boats and corvettes with vessels of more modern design has been a priority since 2010. A similar modernization is also taking place in the Baltic Fleet and the Caspian Flotilla. Utilizing Russia's internal waterways provides the Russian Navy with the capacity to transfer both corvettes and other light units, such as landing craft, among its three western fleets and the Caspian Flotilla as may be required. Analysis in May 2022 suggested that it may be feasible for the Russian Navy even to move its Kilo-class submarines between the Black Sea and the Baltic via
