Trinary Star Shipping is the interplanetary trading and shipping division of the Murasaki Keiretsu.

Trinary Star Shipping (TS) is a commercial cargo transportation and trading fleet that operates throughout the Kikyo Sector. The company is based upon White Harbor Station in the Anisa System System and is owned by the Murasaki Clan.

The Senmu (Executive Director) of the company is Murasaki Natsume, wife of Murasaki Ryosei – the Shachō / CEO of the Murasaki Kereitsu and Daimyō of the Murasaki Clan.

Founded BYE 127, Trinary Star Shipping is the oldest branch of the Murasaki Keiretsu and actually predates the formation of the corporation. In many ways it is the Keiretsu's most successful company, dwarfing with its size and revenue the more recently established branches like Murasaki Technologies and Murasaki Orbital Shipyards. For over a century Trinary Star Shipping has been a market leader and has had a strong presence in the shipping routes throughout the Kikyo Sector, especially in regions around Yamatai's core systems. The company owns a great many freighters of varying sizes – ranging from small in-system cargo haulers and shuttle services up to vast interstellar tankers.

Trinary Star Shipping typically conveys at least 12.8 billion metric tonnes of freight each month. Before its destruction, a good portion of its business was supplying refined ore to Hoshi no Iori for the massive quantity of Star Army of Yamatai construction projects located there, as well as transporting foodstuffs and completed equipment from the megastructure to various inhabited worlds.

In YE 38, Trinary Star Shipping expanded to almost every world in the Yamatai Star Empire as well as securing a regional center in Concourse F on Pisces Station.

The Trinary Star Shipping company operates a fleet of merchanter ships and freighters to conduct trade and ferry cargo as part of its normal operations. Most ships spend weeks or months going along various trade routes between planets and stations before returning to White Harbor for maintenance. Presently, the vast majority of these ships have been manufactured by other organizations unrelated to the Murasaki Keiretsu.

The following is a list of all starships owned and operated by Trinary Star Shipping. Smaller support vessels such as shuttles are not included within this list.
