The ship will most likely be nuclear powered. It will be capable of spending up to 90 days offshore without additional refueling or support.
The Leader-class destroyers are expected to be equipped with Kalibr-NK cruise missiles and S-500 air defense systems.
As exhibited by its mockup, the destroyer will be 200 meters long and 20 meters wide. It will be able to travel at a maximum speed of 32 knots.
The multipurpose warship will have anti-aircraft, anti-ballistic missile, anti-surface and anti-submarine capabilities.
It will further be equipped with P-800 Oniks supersonic anti-ship cruise missiles with a range of more than 300 kilometers. The Zircon hypersonic missiles could also be added to the arsenal.
The next-generation warship will also have a landing pad for two Kamov Ka-27 or Kamov Ka-32 helicopters.
The vertical launch systems (VLS) of the Poliment-Redut system will handle short-range aerial threats. The VLS will be controlled by the Poliment active electronically scanned array (AESA) radar system. The Leader may carry two modules of the navalized version of the Pantsir-M SAM/gun system.
The ship will displace about 17,500 tons, which will make it close enough to Project 1144 Orlan-class heavy missile cruisers in terms of dimensions.
