Serna-class

The Serna class, designated Project 11770, is a series of air cavity system landing craft built for the Russian Navy. Vostochnaya Verf constructed 12 domestic vessels between 1994 and 2014. Of the 17 units originally planned, 16 were completed. An additional four vessels were produced in 1994 under the Project 11771 designation specifically for export.

The design utilizes an air cavity system to support amphibious operations. The craft is configured to transport main battle tanks, armored personnel carriers, or cargo. It can also be utilized for troop transport. The vessel is operated by a crew of five, including two warrant officers, and is powered by two diesel engines with additional diesel generators for onboard systems.

Current operators include the Russian Navy and the United Arab Emirates Navy. One export vessel was previously operated by Estonia but has since been retired from service. Thirteen units remain active in the Russian inventory. During the 2022 Russian invasion of Ukraine, the class saw operational deployment and sustained losses in the Black Sea. On 6 May 2022, a Serna-class craft was destroyed by a Bayraktar TB2 drone while docked at Snake Island. Ukrainian intelligence reported the destruction of a second vessel near Crimea on 10 November 2023.
