Tom Clancy's SSN

Tom Clancy also wrote a book by the same name as a tie-in. SSN is also the title of a board wargame published by Game Designer's Workshop in 1975, and was the first attempt at a serious modern submarine and anti-submarine warfare simulation game published for the entertainment market. It was designed by Stephen Newberg and developed by Marc Miller.

Tom Clancy SSN uses video briefings and fictional news reports to enhance the atmosphere both before and after missions. The view during gameplay is from the perspective of an external trailing rotatable camera. In the game player weapons are limited to submarine-launched torpedoes, with a VLS system for launching Tomahawk missiles at off-map targets (as a mission objective). The player is provided with a simplified scanning screen display for sonar. Thermoclines at various depths are simulated as well, affecting sonar readings and accuracy. Commands are limited to directional steering, ballast tank and periscope controls, basic sonar functions, and weapons targeting and firing, providing an arcade like feel to the game play, as opposed to a true submarine command simulation.

In the near future of 1997, the fragile power balance in China collapses as the death of Deng Xiaoping sparks a coup led by Premier Li Peng. In his bid to seize control, Li Peng seeks to capitalize on newly discovered oil deposits in the Spratly Islands by ordering an invasion. This act ignites a chain reaction: a Chinese submarine attacks a U.S. aircraft carrier escort, which retaliates, destroying the attacker, irreversibly heralding the onset of fully scaled war. The U.S. response involves dispatching a state-of-the-art Los Angeles class attack submarine, USS Cheyenne (SSN‑773), under the command of Captain Bartholomew "Mack" Mackey. Departing from San Diego, Cheyenne receives orders to sail via Pearl Harbor before entering the hostile waters of the South China Sea. At first, the crew operates under strict defensive orders, permitted to engage only if fired upon. However, this restraint soon shatters when a Chinese sub fires, prompting Cheyenne to respond with lethal force. As Cheyenne goes near the conflict zone, she joins the USS Independence carrier group as an escort and on the way, she engages and sinks a Chinese Luda‑class destroyer, its escort, as well as multiple submarines, including Romeo-class threats. While continuing to protect the battle group, the submarine’s missions escalate as Cheyenne ventures into the Spratlys, tasked with destroying a Chinese submarine base and engaging numerous surface and underwater threats. During these operations, Cheyenne sinks additional Luda destroyers, Romeo‑class subs, and even a Han‑class vessel, uncovering evidence of Russian involvement within Chinese forces. The theatre of war intensifies as Cheyenne executes patrol duties, launches Tomahawk strikes on coastal airfields, and defends an American oil rig called Benthic Adventure, now under attack. This period sees the sub fend off multiple waves of Chinese naval aggression, including a massive task force threatening the carrier group. Amid escalating conflict, the submarine makes logistics stops, including at Subic Bay, before launching strikes on Russian-crewed subs embedded in Chinese forces. The mission then pivots to facilitating the safe return of deposed Chinese leader Jiang Zemin, who resurfaces in Taiwan. Cheyenne enters the mine-infested Formosa Strait, defending Jiang’s convoy from further threats. The culminating confrontation unfolds when Cheyenne hunts down a Russian Typhoon-class SSBN, supported by Akula escorts, in a high-stakes mission to preempt a nuclear threat. Emerging victorious, Cheyenne presses on, clearing enemy submarines surrounding Taiwan and ensuring Jiang's safe passage back to mainland China. In a final act of diplomacy, Jiang declares a ceasefire, effectively bringing the war in the South China Sea to an end. Captain Mackey’s crew earns commendations from both American and Chinese authorities.
