Task Force 63 was a Starfleet task force extant in the late 24th century. It was part of the Starfleet Sixth Fleet. In 2377-78, Commodore John Risely-Pritchard was Task Force 63's commanding officer aboard the flagship USS Thunderchild (an Akira-class heavy cruiser commanded by Captain James Bakken). Task Force 63, deployed on patrol missions, was then homeported at Deep Space 3. (Ships of the Star Fleet, Vol. 4: Star Fleet Operating Forces. )
