The USS Tomcat science Department consists of the corps of officers who specialize in both scientific and medical research and control functions aboard the USS Tomcat. Members of the sciences division specialized in sensors, research, theoretical and physical laboratory work, biological studies, and also as technicians, medics, and surgeons.

Officers who belonged to the sciences division sometimes wore the division color of a department other than that in which they specialized. For example, if a science officer became a department head, he might have worn the colors of command or if he had a dual specialty in an operations division department, an alternate color might have been worn. On the uniforms used from 2350’s onward, blue had again become the sciences division color. Since the USS Tomcat is attached to the Star Fleet Marine Corps, Marines in the science division are denoted with a blue strip on their uniforms.

Science officers are responsible for observing and theorizing explanations for strange or seemingly unexplainable circumstances. The science officer is also responsible for sensor readings. General survey parties require the direction of the science officer. In a medical emergency, the findings of the science officer are heavily relied upon. The science officer is required to keep sufficient data. They are also required to supply the commanding officer with all reports, observations, and speculations that might have affected the safety of their vessel.
