The Il'Emaar (Courier)-class Merchant Transport is a new starship design of the T'au Empire developed as part of the Kor'or'vesh fleet initiative, and was a response to the need for a new kind of fast transport that could make long, deep dives in support of T'au fleets and quickly replenish forward-deployed flotillas.
The T'au Empire's long and protracted war with the Orks during their Second Sphere Expansion proved early on that the numerous but relatively fragile merchantmen that were the life-blood of the rapidly expanding T'au Empire were woefully inadequate.
Continuing raids decimated the fleets of these small ships, leading to the development of a much larger class of heavily armed transport in the form of the Il'Fannor. As time progressed, smaller transport classes almost disappeared entirely until the development if the Il'Emaar.
The T'au Empire thrives on the trade between its Septs, and transports are the workhorses of the trade routes. While this vessel was originally designed to support the Kor'or'vesh, the obvious utility of these vessels was expanded to the greater Empire, and now these easily produced starships are common sights throughout T'au space and beyond.
Small vessels, with limited crews, Il'Emaar (Courier)-class Merchant Transports are only armed for self-defence, with a single prow Railgun battery, one defensive turret, and standard T'au starship shielding. As befits a transport, Il'Emaar also have large holds for transporting goods and supplies.
