 The primary intelligence agency that needed the Titan IV's launch capabilities was the National Reconnaissance Office (NRO).When it was being produced, the Titan IV was the most powerful uncrewed rocket available to the United States, with proportionally high manufacturing and operations expenses.By the time the Titan IV became operational, the requirements of the Department of Defense and the NRO for launching satellites had tapered off due to improvements in the longevity of reconnaissance satellites and the declining demand for reconnaissance that followed the internal disintegration of the Soviet Union.
