The science vessel

Science vessels have been in use since at least 2478.[2]


The terrans of the Koprulu Sector built Explorer-class science vessels to conduct a wide range of research and development projects, stationed at points throughout the Koprulu Sector and beyond to study anomalous phenomena[3] and early on, search for alien life.[2] In addition, the Confederacy's Epsilon Squadron used science vessels extensively for border surveillance and study.[3] Explorer-class commanders and crewmen required a PEB (Preferred Experience Base) of any hard science and electronic warfare.[4] The primary function of the science vessel was the employment of its detection abilities. Other functions, with the appropriate equipment, included the creation of a defensive matrix, the generation of a short ranged EMP[3] (alternatively this could be detonated at a distance via the launching of a warhead)[5] and irradiation of a target via a high-energy stream of radioactive particles developed from technologies in nuclear waste disposal, saturating it with damaging energy.[3] For increased energy output, a titan reactor could be installed.[3] All science vessels possessed Ghost Program files, stored in a secure room at the bottom of the vessel, in case a ghost required "repair" (what amounted to medical aid in the program).[6]

When contact with the protoss and zerg devolved into open warfare, many Explorers were requisitioned by military authorities to provide electronic warfare and support for forces in the field,[3] along with aiding the research and development of new weapons and technologies.[4]

After the Brood War, the Terran Dominion substituted the raven for the expensive science vessel in the battlefield support role.[7]


During the Second Great War, Raynor's Raiders were able to develop a new class of science vessel. This model can carry out hull repairs through nano-technology and retains the irradiation function from its predecessor.[8] The Dominion Armed Forces were seen using this type of science vessel later in the war.[9]


The Kurzweil-class science vessel is an experimental craft, designed by Valerian Mengsk, and in service by 2505.[10]

Science vessels acted as unseen support units in StarCraft: Ghost. Nova was able to call down irradiation,[11] EMPs and a scan function that gave info on enemy strengths, weaknesses and history.[12]
