Big Gun Heavy Defenses:

Ratios:

* Build Rocket Launchers as your fodder.
* Build 1 Light Laser for every 2 Rocket Launchers.
* Build 1 Heavy Laser for every 10 Rocket Launchers.
* Build 1 Ion Cannon for every 25 Rocket Launchers.
* Build 1 Small Shield Dome when you reach 10 Rocket Launchers
* Build 1 Gauss Cannon for every 50 Rocket Launchers.
* Build 1 Plasma Turret for every 100 Rocket Launchers.
* Build 1 Large Shield Dome when you reach 100 Rocket Launchers
* Build Anti-ballistic Missiles when you reach 100 Rocket Launchers

That means when you acquire 1000 Rocket Launchers, you should have:

* 500 Light Lasers
* 100 Heavy Lasers
* 40 Ion Cannons
* 20 Gauss Cannons
* 10 Plasma Turret
* 1 Small Shield Dome
* 1 Large Shield Dome
* some Anti-ballistic Missiles

The Total Cost of this method is:

* 4.390.000 Metal
* 1.550.000 Crystal
* 340.000 Deuterium
* + costs of silos and missiles

Some critics of this setup would may point out that there are too many big guns (Gauss Cannons & Plasma Turrets) in this type of defense; however, in order to deter attack from higher level players, Gauss and Plasma Turrets are necessary in order to make sure a defender can damage an attacker's upper tier ships (i.e. Battleships, Bombers, and Destroyers), since upper tier vessels can easily break through defenses lacking in big guns.

The Heavy Lasers included in this strategy are included to clear a path through the Light Fighters that players like to use as fodder in their raiding fleets, and the Ion Cannons are there for their strong shields.
