The Tharkad Aerospace Group (better known as TAG), is a Lyran based DropShip manufacturing company. The company is noted as being one of the oldest manufacturers of DropShips still active.


TAG was founded in the twenty-fifth century, just after the Lyran Commonwealth government chose Tharkad as its new capital world.

The company situated its main manufacturing facilities in a set of orbital shipyards which have been given the name of Aesiria. From the yards, the yards produced during times leading to the Succession Wars a mix of Civilian and Military type DropShips.

After the League fell, the company came into hard times, with production falling off substantially. The company opened its orbital shipyards for repair and refit work for anyone, including local corporate rivals.

By the thirty-first century, TAG had developed something of a good working relationship with its friendly rival, Semier Data Tron. In this time, Semier granted TAG a joint license to manufacture Fortress Class DropShips. TAG began refitting older Fortress Class DropShips with the Movem-XL Drive from its Mammoth production line.[1]

Prior to the Jihad, TAG's corporate leadership begun bolstering its private aerospace defense force. In turn, its rival Semier did the same for its surface factories and orbital facilities. This produced question if leadership of both companies had lost their fondness each other begun turn bitter rivalry.[2]

During the Jihad and Word of Blake occupation of Tharkad, TAG's factories took heavy losses. The manufacturing facilities were reduced to a quarter of their pre-Jihad output. With only 15% of their workforce coming through the Jihad, this isn't surprising.[3] Aesiria Station was only producing Mule and Intruder class DropShips in 3079.[4]


The Company's CEO in 3067 was Duke Lawrence Rothschild.[2]

As to location, two sourcebooks show that TAG was originally on Gibbs. However, Handbook: House Steiner has the shipyards in Tharkad's orbit with a history stretching to its founding in the 2400s. Writers of BattleTech have ruled that TAG's location over Gibbs was an error and it is and has always been in orbit of Tharkad and that the original Objective Raids was in error.[7]
