Its dense double hull, modeled on that of a Russian Typhoon-class supersub, had also been reinforced with a unique, impact-absorbing alloy found only in one remote and isolated African kingdom. For offense it used lasers, Tomahawk missals ordinary, and Shkval, an experimental torpedo developed by the Russians in the late seventies, and improved upon since, could reach a top speed of 100 meters per second, while an ordinary torpedo could travel at best 130 kilometers per hour; it operated on the principle of supercavitation, which reduced hydrodynamic drag by enclosing the torpedo within a self-generated bubble of water vapor and gas.
