First fielded in 2765, the Atlas II was designed by the Hegemony Research and Development Department, Weapons Division of the original Star League to maintain the technological edge over the other Great Houses. It was exclusively for the SLDF's Royal Regiments.
In 2785, when General Aleksandr Kerensky put out his call for loyal forces to join him in his Exodus, every Atlas II pilot responded and left with him, leaving none of these designs behind. These 'Mechs are prized by the Clans when they were found. One such 'Mech was spotted in 3052 during the Battle of Tukayyid.
In the early 3070s, the design was resurrected by the Word of Blake when they captured Hesperus II's factories. After the liberation of Defiance Industries, Devlin Stone's coalition forces kept the 'Mechs in production.
 Weapons and Equipment
The Atlas II is armed with an array of weaponry, including an LB-X Autocannon/10, a pair of ER Large Lasers, and a 20-tube Long Range Missile Launcher for long range attacks. For close range combat, the 'Mech is equipped with a pair of Medium Pulse Lasers and a Holly Six Pack. In addition, the 'Mech has been given CASE for both sides of the torso in order to keep an ammunition cook-off from consuming the 'Mech.
The weapons payload gives the design more broad range attack ability versus the Atlas's brawling weaponry and its limited long range attack capacities.
 Custom Variants
- AS7-D-H Devlin
- Used by Devlin Stone, this Atlas variant used a combination of Clan and Inner Sphere technology to maximize survival. The ER Large Lasers, XL Engine, and heat sinks came from Clan sources. A Heavy Duty Gyro is also fitted to enhance survivability. The LRM and SRM launchers have been replaced by a single MML-9 with an Artemis IV system. CASE II protects each side torso from ammunition explosions, an Angel ECM suite foils Blakist communications gear, and for additional protection the left torso carries an Anti-Missile System. For additional protection the cockpit, sensors, and life support system in the head are all armored. BV (2.0) = 2,491
