Missile launching satellite

Here’s a mid-1980’s Martin Marietta painting depicting a satellite  capable of holding and launching a multitude of missiles. As this came from a promotional video dealing with the Star Wars program, these missiles are presumably anti-missile missiles. Oddly, they seem to launch from both ends of the satellite.

Was this painting derived from a serious engineering design? I don’t know, but I do know that it bears an uncanny resemblance to the Soviet bomb satellite model built for (but cut from) “2001: A Space Odyssey.”
