Compared to the Titan 34D, the CT-3 Titan LV had an elongated second stage and an enlarged warhead to realize the possibility of launching two spacecraft simultaneously. In total, four launches were made, of which one was unsuccessful. Due to the high launch cost (higher than the competing Arian-4) in 1992, the launch of the launch vehicle was discontinued.
