Descended from an ancient defense contractor based on Terra, Grumman Amalgamated was once a proud and important part of interstellar commerce. Today, their output is limited to the Ontos and a few other combat vehicles. They shouldn't be discounted however, as many of the components they produce are also used in other companies' products. In particular the Light Gauss Rifle they produce under license from Imperator is popular with many units. As of 3067, Grumman focuses on production of the Ontos and several variants.
In 3139 forces from the Free Worlds raided Shiro III, which was a member of the independent Duchy of Andurien. The target of the raid was the Grumman Amalgamated plant, and the defending Andurien forces quickly pressed Lamprey Transport Helicopters into service, first by using their SRM launchers to ignite fires to channel and slow the League forces, and then to deploy battle armor squads in the rear area of the League echelons. With the infantry deployed, the Lampreys then engaged the League BattleMech forces, forcing one 'Mech to retreat and destroying a second despite taking several direct hits from heavy weapons.
An apocryphal source (Bruderkampf) names one Alfredo Garcia of Shiro III as Grumman Amalgamated's CEO and co-owner at an unspecified time period (implied to be towards the end of the Succession Wars era) when the Duchy of Andurien is still serving House Marik.
