The navy has announced that it will procure over 7-10 years 28 (or more) destroyers belonging to two classes dubbed, the Praetor class DDGN. They are based on an extremely lengthened and broadened KDX-III hull, while employing many new stealth technologies, such as the Advanced Enclosed Mast/Sensor (AEM/S) System. These battlecruisers are well-armed to provide fleet defence against a wide range of threats. It also employs the SURTASS II-M system which is a smaller version of the SURTASS II system.

The Praetor class DDGNs are among the largest of cruisers that utilize the S-500F battle management system and uses a state of the art torpedo defence system that uses a towed decoy to simulate the ship's acoustic characteristics, and also a combination of an evolved RBS-12000 mortar type firing decoys and hard kill torpedo rockets, counter torpedoes (supercavitating Skhval type) and supercavitating bullets.

  • Surface Ship Torpedo Defence for hard and soft kill torpedo defence using decoys and counter torpedoes (utilizing the 533mm tubes)
  • Nulka ship decoy system

Power and HullEdit

  • Propulsion: Nuclear with electric drive (2 Nuclear reactors delivering ~200,000 hp for up to 35 knots. Approximately similar to the Kirov's reactor power output)
  • Backup power: 2 turbines delivering ~30MWt each (to allow at least 10 knots speed)
  • Hanger and landing pad for 2 helicopters and launching UAVs.
  • standard displacement estimated ~ 16,000 tonnes
  • total displacement estimated ~ 19,000 tonnes
  • Cost estimated ~ 2-3 billion
