Nikita missile

The Nikita Missile is a remote-controlled missile whose functions were derived from micro air vehicles. Its primary function was as a reconnaissance scouting drone to scout out enemy positions, although it also included a warhead in case it was to be utilized as a weapon.

During the events of the Shadow Moses Incident in 2005, the Sons of Big Boss stored some Nikita missiles in the armory as well as in the main lobby of the first basement floor of the Warhead Storage Building. Snake, under the advice of someone identifying himself as "Deepthroat", procured some Nikita missiles so he could destroy the generator for an electric floor system so he could access Otacon's lab easily. Snake later used the Nikita missiles to his advantage when fighting Vulcan Raven in the warehouse.

During the events of the Big Shell Incident in 2009, Raiden procured some Nikita missiles in the flooded Basement 2 area of Shell Core 2, in order to deactivate the electric floor that was currently active outside of President Johnson's cell. Because the Sons of Liberty, when taking over the Big Shell, set up an electronic interference field around the Big Shell with the intention of preventing any UAVs that didn't belong to themselves from infiltrating the Big Shell, it was only able to function indoors.

Although they weren't used during this time, Snake remembered his using them against the electric floor generator, and expressed irritation that the missile, due to being overloaded with electronics, having a warhead that only had enough power to temporarily shut down the electric floor generator rather than destroy it outright, which was later demonstrated when Otacon reactivated the electric floor in order to stop a Gekko that was patrolling the area.
