The Soviets run a whole program of satellite interceptors in the 60s: http://www.russianspaceweb.com/is.html

It was a maneuverable satellite designed to destroy an enemy satellite by collision. They even launched a special armored satellite that could be used as a target for multiple test interceptions.

Also the R-23M Kartech[1], test fired in 1975.

    The results of the tests still remain classified. However it appears that the
    follow-up Almaz station was to be equipped with a pair of interceptor missiles
    rather than a cannon.
