Tom Clancy's SSN
Tom Clancy's SSN is a submarine simulation video game released in 1996 for Microsoft Windows, in which players command the USS Cheyenne, an Improved Los Angeles-class (688i) nuclear-powered attack submarine, during a fictional escalating conflict with China in the South China Sea.[1][2]
Developed by Clancy Interactive Entertainment and published by Simon & Schuster Interactive, the game features a 15-mission single-player campaign emphasizing anti-submarine warfare, surface ship engagements, and intelligence operations, with real-time control over submarine systems including sonar, weapons firing, and crew management.[3][4]
The storyline, authored by Tom Clancy, draws on his expertise in naval tactics depicted in works like The Hunt for Red October, placing the player in command decisions amid a limited war scenario that avoids nuclear escalation.[2]
While praised for its detailed simulation of submarine operations and Clancy's narrative integration, the title incorporates simplified visuals and mechanics, such as direct viewing of surface targets, diverging from stricter realism in later submarine sims.[4][5]
