First introduced in 2751 by the Terran Hegemony, the Extended-Range Particle Projector Cannon, or ER PPC for short, has a greatly increased range than that of a standard PPC. Capable of causing extreme damage at long range, it unfortunately generates a tremendous amount of heat, and so can be difficult to use effectively. The ER PPC is also noticable for having no minimal range.
After becoming lostech during the Succession Wars, the ER PPC was first reintroduced to the Inner Sphere in 3037 by the Draconis Combine. By this point the Clans had greatly refined the weapon, with slight reductions in size and weight, but most notably boosting its damage by fifty percent, making it capable of shaving off almost a ton of armor in a single hit. Despite the best efforts of the Great Houses, none have been able to successfully replicate this increase, though their efforts have resulted in the Heavy PPC which matches the damage potential (and heat) of the Clan weapon and has also led to devices such as the PPC Capacitor that can emulate the increase to a degree.
ER PPCs are manufactured on the following planets:
Aberdovey Mark XXX
Blankenburg Technologies 200
Ceres Arms Warrior
Johnston High Speed
Developed by Martinson Armaments for their SPT-N2 Spartan, the Kinslaughter H-Class was considered the apex of the ER PPC during the Star League era, noted for its inclusion of special insulating cones that made the weapon both easier to maintain and ensured it generated less heat than many other models of ER PPCs.  During the Clan Invasion era only ComStar and the Word of Blake were capable of building the Kinslaughter H-Class.

Type DDS "Kingston"
The Type DDS "Kingston" Extended-Range Particle Projection Cannon is one of the more modern and common types of Clan-spec ER PPCs in Clan and the Inner Sphere space following the FedCom Civil War. Debuted by Clan Cloud Cobra around 3059 in time for use on their new Four Legged BattleMech the Stalking Spider, Clan Star Adder and Clan Diamond Shark would secure the designs for the weapon for use on updated Phoenix updates of the venerable Glass Spider and Warhammer IIC manufactured in the Clan Homeworlds. The Diamond Sharks' forced evacuation from the Homeworlds would also result in the start of manufacture of the weapon in the Inner Sphere as well,  which the mercantile Clan Sea Fox would offer to Clan and Inner Sphere buyers such as the Capellan Confederation and possibly the Federated Suns.
