The Pollux ADA Heavy Tank was a dedicated anti-aircraft artillery vehicle designed to serve as a component of Terran Hegemony's planetary defense forces. The tank's creation was due in part to Hegemony worlds feeling they were left undefended due to the focus of using a Space Defense System as their only means of defense. The Pollux's weapons systems were geared to handle airborne threats on the surface. First Lord Jonathan Cameron authorized the creation of the vehicle to appease these worlds' governments. However, the Pollux also was appealing to the SLDF, which had sought dedicated anti-aircraft defense vehicles since the days of the Reunification War.

Hadley Incorporated was asked by the SLDF to build the vehicles, however up to that time they had only built GAD-14 automatic air defense turrets for SLDF's facilities. They teamed with GM who helped them design a combat vehicle chassis to mount a down-scaled version of the GAD-14 turret. After production began in the early twenty-eighth century, the vehicle was quietly deployed evenly to both SLDF and newly created planetary ADA (air defense artillery) garrison units. However, the practice was ended in 2718 when officials complained that these units, which were supposed to be deployed solely to their planet garrisons, were going to SLDF's ADA units.

During the Periphery Uprising, General Aleksandr Kerensky quietly transferred specialized Pollux combat units to the regular army as part his efforts put down rebels in the Periphery. These Pollux ADA units were ironically deployed as part Kerensky's liberation force to free Hegemony worlds that it was designed to defend.[2]

Weapons and Equipment[edit]

Based on Hadley's highly automated air-defense turret, the Pollux's main weapons would remain the same. The Hegemony Arms DAT/96 Sniper Artillery Piece would be mounted in turret along with Blankenburg LB 10-X Autocannon. Both guns would carry typically only flak ammunition, with 3 tons space dedicated for each weapon. While a turret mounted Medium Laser & forward facing Small Pulse Laser would give the tank some means of close-in self-defense. Also protecting the tank is 6 tons of Grumman-5 Ferro-Fibrous armor giving its hull modest strength ward off light attacks as its escorts take out would be attackers.

Powering the vehicle is a GM 225-rated standard Fusion Engine, giving the vehicles modest speeds to keep with typical vehicle formation and heavy 'Mechs.[3]


  • Pollux II ADA Tank 
    Developed and used by the ComGuard rebuilt First Division, this variant of the Pollux uses a Light Fusion Engine for power. It carries a Guardian ECM Suite and a Small X-Pulse Laser in the front. The turret carries a Silver Bullet Gauss Rifle and an Arrow IV missile launcher as air defense weapons, along with an additional Small X-Pulse Laser. The Silver Bullet Gauss rifle has three tons of ammunition, while the Arrow launcher has six. The rear armor of the tank is doubled as well. BV (2.0) = 1,224[4]


The Vehicle's Armanent fluff names individual Sniper weapon as a cannon. However, this not a true Sniper Artillery Cannon, which lighter and short-ranged than a regular Sniper Artillery Piece. Pollux's record sheet & weapon break down shows that Sniper listed is regular Artillery Piece version.[5]
