Originally a small company producing various military parts and sub-systems, with the loss of Terran manufacturing capacity ComStar chose to upgrade the company's facilities to meet the needs of both the Com Guard and KungsArmé. The new start-up quickly obtained contracts to produce both new as well as classic designs, ensuring its profitability.
When Clan Ghost Bear joined the Free Rasalhague Republic during the Jihad, Grumium Creations failed to secure funding to upgrade its production lines. As a result, the plant shut down the Crockett line. As of 3079 Grumium Creations had lost no personnel to the conflict, though production was operating at 60% of its maximum capacity, but in 3080 a Level III from a Manei Domini Shadow Division struck Grumium and managed to penetrate the Grumium Creations compound. The 2nd Kavalleri Cluster stationed on world was able to eject the Word of Blake forces, at the cost of a third of Kavalleri's strength, but not before the mothballed Crockett line was smashed.
