The Firestorm-class recon craft was designed with secrecy in mind. At full speed it would produce a sonic boom that would announce its presence unmistakably; however, while filling its purpose as a reconnaissance craft it was virtually invisible to most small sensors. This did not make it immune from detection by ships, however. An orbiting vessel, if it knew to look, could easily spot the Firestorm using active sensors.
