Large landing ship "Ivan Gren"

The development of the next generation large landing ships began at the turn of the century. The basic project has been repeatedly adjusted in accordance with the changing views of the Russian Navy on the tactics of using and operating landing craft. Events in Syria once again confirmed that such ships are in great demand. Logistical support for the grouping of Russian troops and the government army deployed in the Arab Republic required the active use of the large landing ships projects 1171 and 775 of the Black Sea Fleet, involving the same type ships of the Northern and even the Pacific Fleets. The age of many is about fifty years or more, which, however, did not affect the successful nature of their use. Competent decisions of designers of the Nevsky Design Bureau make themselves felt.

A reliable, robust housing, coupled with a simple power installation, allow domestic past-generation large landing ships to still work as a Kalashnikov assault rifle. “The weapon must be simple and reliable. Trying to bring this idea to life, we strive to make the new generation ship as reliable as its predecessors. We really hope that a big series will go,” Yukhnin explains.

According to the results of tests and initial operation, the Russian Navy is satisfied with the technical solutions implemented in the ship of Project 11711. Accordingly, the Ministry of Defence decided to build another pair of such ships. "Vladimir Andreev" and "Vasily Trushin" laid at the Yantar Shipyard in the spring of this year. At the same time, the customer made a number of comments and suggestions. Based on them, a decision was made to improve the operational characteristics of Project 11711 ships. So, the aft superstructure moved forward, which, together with other measures, allowed the designers to increase the size of the hangar and helipad. The composition of the air group grew to four Ka-27s. This is a significant increase, against the background of the fact that the large landing ships of past generations did not have permanent helicopters at all, and could only temporarily take one machine to the upper deck section.

The greatest length increased by thirty meters, up to 150, width (on design waterline) - by two meters, up to 19.5, displacement - by two thousand tons (standard 7000, total 8000 tons). The possibility of using the ship and unmanned aerial vehicle is claimed. The ship will additionally receive a 76-mm artillery mount and an integrated electronic warfare subsystem. At the same time, the remaining technical solutions were preserved, so it was decided to keep the project number. For the first time, a large-scale model of the ship of the adjusted project (11711E) was publicly presented at IMDS’2019.
