The Project 21810 medium landing ship is designed to sealift and land assault troops and military equipment on unequipped shore; destroy enemy forces on the shore before landing; provide its self-defense.
The Project 21810 medium landing ship has improved design and seaworthiness, owing to the use of corrosion-resistant alloys, extruded sections and panels, and a powerful power plant.
Its peculiarity is a multiple rocket system designed to provide close support for the equipment being landed. Such a combination of a landing ship and fire support means indicates the mission of the ships in the face of strong enemy resistance.
The ship is equipped with an automated movement and facilities management system.
The Project 21810 medium landing ship is capable of delivering loads to the coastline areas within 2,500 miles.
Its seaworthiness makes it possible to use weapons and equipment:
- in sea point up to 4 inclusive ─ with no limits;
- in sea point up to 5 inclusive ─ with limitations on speed and maneuvering with respect to the wind and waves.
The ship stays afloat with any two adjacent main watertight compartments flooded.
