S-2 Standard Missile

The System-2 Standard Missile series is a family of air-to-air, air to surface, surface-to-air, and surface-to-surface missiles, based on pre-existing designs of the Babkhan "Ubiquity" air-to-air missile, but with updated electronics, and modular target guidance and or homing-seeker sensors that are interchangeable depending upon selected and programmeable mission types.

Characterised as an "anti-aircraft missile that can be flung at anything", the design characteristics of the S-2, originally developed for the GAV(P)-5 Nereid, tended to lend towards a reduction in production costs through modularity - the interchangeability of parts in a manner consistent with the core components and electronics of the missile - and an inherent adaptability that suited the missile to a variety of launch platforms.
