Interstellar Alliance Nolo'Tar Class Frigate

Lightly armed for a Ranger vessel, the Nolo’Tar is a throwback to the generation that survived Valen. It was used to bring teams of Rangers from one place to another without having to resort to masses of Flyers or Nials. Especially useful in training missions and practice evacuations, this transportation frigate became a common sight during Valen’s great Shadow War but fell out of use during the following thousand years.

It was resurrected quickly when the Rangers began to deploy in larger numbers again during the next Shadow War, mostly to ferry refugees from planet to planet when the war drew too near. While not atmospheric in and of themselves, they carry a number of smaller shuttlecraft to bring people and supplies aboard through their oversized hangars. While rarely allowing outsiders to do so, the Nolo’Tar could possibly house up to twice their common allotment of shuttles or Flyers if the need arose – which it did several times in 2261, when the First Ones were destroying whole planets in their war.

One particular and heavily modified variant of the Nolo’Tar hull, the Liandra, was fitted with several experimental weapons and control systems by the Anla’shok just after the Earth-Minbari War and put into storage and basically forgotten during the rise of the next Shadow War. It was used only in few minor missions, until a time where it would later be needed by a controversial young Ranger named David Martel in his battles against a mysterious foe called ‘The Hand of God’.
