Perimeter Action Group 6 (also known as PA Group 6) was a Starfleet battle force extant in the late 23rd century. (Ships of the Star Fleet, vol. 2) PA Group 6 consisted of USS Akitsu, USS Buran, USS Akita and other vessels. It was homeported at Starbase 25. Perimeter action groups may have been the counterpart of what were called pursuit groups in other continuities.
