Bars are shown relative to the strongest structure of its class (Achille). Defense is static — it has no speed or cargo hold. "Weapon points" — one structure's contribution to combat power.

Effectiveness against fleets

"Rock-paper-scissors": a structure has its own effectiveness multiplier for each ship type. ×2…×5 — how much harder it hits a favorable target; ×0.5 — an unfavorable one. On top of that, combat applies rapidfire ×1.5 (a separate multiplier, it is not multiplied).

Effective against

"Rapidfire" is a combat mechanic of the engine. More details — section Combat system.

Calculator: defense versus ship

Pick a structure and a ship — we'll show the defense's effectiveness multiplier against that ship.

Requirements

To build this structure, you need to raise the following to the required level:

Defense is built on the planet (the same place as the fleet). Technologies are leveled up in the Laboratory — section Research.

Description

The second-class anti-siege gun Achilles DM was designed specifically to deal with the Taran FM bombers. This is the only mobile PKO in the middle class. Possessing an out-of-orbit sanitation weapon, these systems easily hit bombers even on approach to the planet. Themselves remain inaccessible to guided bombs. System deployment time between mobile and combat mode - no more than 30 seconds
