Soo.. contemporary stuff.. I like alternate space programs that are a bit more.. exciting.. than the endless budget cuts of real life. This is an image challenge, so excuse the big image: It's the sub-orbital warhead platform so chillingly envisioned for Assignment: Earth, with some very bleak flavor quotes from TOS. From that dialogue, it seems Gary Seven was not particularly succesful. Or at least the Soviets had orbital nukes to wich the Americans responded. I suspect there may be room for the Dyna-Soar or similar craft in Trek's timeline to complement the orbital platforms (the Outer Space Treaty apparently was not created in the TOS timeline). The episode only mentions one warhead on the launched platform, but in general they are described as 'multi-warhead'. The one sabotaged in TOS is probably a lighter version or some kind of prototype.
