Modern Naval Warfare

Modern Naval Warfare is a tactical submarine simulation in which you command advanced nuclear-powered submarines. You operate their systems and weapons, interpret acoustic and sensor data, and take part in missions across the South China Sea.

Submarines and the world

The simulation uses real-world GIS data to represent the environment, with physically based rendering and world lighting. Volumetric clouds, dynamic GIS-assisted weather and a multi-layered spectral wave system shape conditions at sea. The world also includes digital twins of modern military and civilian platforms, with civilian traffic assisted by GIS-AIS data.

You can explore accurate 3D representations of the Virginia class (Blocks I-IV) Combat Information Center, with fully clickable, feature-complete control stations.

Acoustic and physical systems

Sound serves as your primary means of detection. A 3D sound propagation model calculates transients, flow noise and sounds from individual components such as engines, pumps and propellers in real time. FFT analysis supports Narrowband, LOFAR and DEMON applications, with results shaped by the characteristics of specific sonar arrays.

Objects use real-time hydrodynamic and hydrostatic calculations. Weapons movement, explosions and material reactions to underwater pressure are physics-based, while damage control includes detailed damage modeling and volumetric flooding based on shipbuilding concepts such as permeability.

Stations and equipment

You take on different crew roles through station interfaces in their native languages. At the Pilot Station, you control depth, speed, course, trimming and masts. The SONAR Station covers Broadband, Narrowband, Active Intercept and Tactical Decision Aid; Fire Control provides advanced TMA (Target Motion Analysis), interactive rulers and mission planners for Harpoon and TLAM missiles. ESM and RADAR stations let you intercept threats and monitor AIS signals.

The submarines carry RADAR, SONAR and EO/IR sensors, as well as electronic warfare equipment. RF signal propagation is affected by wavelength, line of sight and antenna configuration. You can deploy torpedoes, multi-stage missiles with individual stage envelopes and mines, and defend the boat with noisemakers, sonar decoys, chaff and flares. Navigation systems include INS, GPS/GNSS, Tercom and DSMAC.

Campaign and operations

The 18-mission campaign takes place in the South China Sea. Its operations include Anti-Submarine Warfare (ASW), convoy hunts, special forces insertion and espionage. You can also play a 3-mission training sequence or create challenges with the quick mission editor. The game supports both lone operations and taking part in a strike group.
