Slipstream missiles are a class of ballistic missiles which make use of FTL drives to acheive extreme speeds and are able to strike planets many light-years away within a timeframe of minutes.
After the invention of the TransLight Drive in 2076, military powers began to look into the technology for use on weapons systems. Many prototypes were developed, the most successful being the British SM-1 missile, with a range of around 80 lightyears and capable of carrying a nuclear payload, it was the most powerful weapon every developed.
After the controversy surrounding a Russian missile test, the UN outlawed slipstream missiles and all development and research ceased.
In 2230, once again slipstream missiles came into the spotlight after a home-made slipstream missile impacted the Inner Colony world of Tauron, killing 563 people. The trajectory of the missile indicated a launch site on the Inner Colony world of Lima
The first ever deployment of a Slipstream Missile was the British SM-1, which was deployed on ground stations in Staffordshire, England circa 2080, for the purpose of defence from extrenal threats, which was a great fear at the time. The missile's standard payload was a MMX-303 nuclear payload, which contained 8 IRV's, each carrying a 25 Mt nuclear warhead, for a total yield of 200 Mt (if used in direct impact mode).
