This design was inspired by an old DOS game, Star Legions. It's envisioned essentially as a giant weapon turret rather than military facility. The Star Legions version was a "Planetary Defence Phaser", which would land hits on orbiting war vessels.
It is probably not very good conventionally but the faction that designed it inhabits the moon while its rivals inhabit the earth. If war erupts in Earth Orbit, Lunar beam superiority will be essential. It doesn't quite have the range to compete with the Atlantis Council 20cm lasers, but they don't have the fire control tech to take advantage of that. At the worst, it drastically reduces their effective firepower. Protection of the orbiting habitats is critical, and any hit above strength 3 will penetrate their armor.
Eyeing the cost - rather than tonnage - also gave me an idea.

This design is classed as a Planetary Defence Centre and can be pre-fabricated in 4 sections The 'Antiproton Array' is a strength-3 particle beam with a level 1 capacitor. Weapon cost scales pretty much directly with capacitor strength so for almost the same cost as the Zeus, this version can mount 24 particle mounts. I went with the Str3 so I could keep the recharge reasonable.
