The older primary telescope at Green Bank Observatory was a 300-foot-dish Radio Telescope, now commonly referred to as the Green Bank 300ft (Radio) Telescope, the Green Bank 91m Telescope, the Green Bank 90m Telescope, or GB300. It went into service in 1962 and collapsed in 1988, and the Green Bank Telescope (GBT) is a replacement.
