Scinfaxi

Lore & Background

The Scinfaxi was built as part of Yuktobania's secret superweapon program, intended to counter Osean naval superiority. Unlike conventional submarines, it carries a flight deck and hangar capable of launching and recovering multiple fighter jets, allowing it to project air power far from any land base. Its most feared weapon is a battery of vertical launch system tubes that can fire ballistic missiles armed with cluster warheads, devastating large areas in a single salvo. The submarine's design emphasizes stealth and endurance, with a nuclear reactor enabling prolonged submerged operations. Its hull is reinforced to withstand depth charges and torpedoes, making it a difficult target to sink. The Scinfaxi operates as a fleet killer, able to cripple enemy carrier groups before they can respond, and its missile strikes can level ground installations from hundreds of kilometers away. In Yuktobanian doctrine, the Scinfaxi is a strategic asset, deployed only for critical missions. Its existence was kept secret until it was activated during the war, catching Osean forces off guard. The submarine's combination of air wing and missile arsenal makes it a self-contained task force, capable of independent action deep in enemy territory.

In Their Own Story

The ocean was a black mirror under the moonless sky. Deep below, the Scinfaxi moved like a leviathan, its reactors humming a low, constant thrum. In the control room, Captain Voronov watched the tactical display as missile tubes flooded and hatches cycled. 'Surface to launch altitude,' he ordered. The submarine rose silently, breaking the waves with barely a ripple. On the flight deck, YF-23 Black Widows roared to life, their engines piercing the night. 'Launch all birds,' Voronov said. The fighters screamed into the sky, and moments later, the first VLS cells opened. Fire and smoke erupted as missiles climbed on pillars of flame, arcing toward distant Osean bases. Voronov allowed himself a thin smile. 'Let them know we are here.'

Reader's Guide

The Scinfaxi is a hybrid submarine and aircraft carrier, designed to overwhelm enemies with both air power and missile strikes. It carries a complement of advanced fighters, typically YF-23 Black Widows, which can be launched from its deck while surfaced. Its primary offensive capability is its VLS missile system, which fires ballistic missiles with cluster warheads that blanket a wide area, making them devastating against ships and ground targets alike. In combat, the Scinfaxi relies on stealth and surprise: it surfaces only to launch aircraft or missiles, then submerges to evade counterattacks—a hit-and-run predator that strikes without warning and vanishes into the abyss.
