There are initally 3 defense buildings in the game currently. More will be given from City Hall awards on later game.

 1- Lunar Security (Police Station) fires slow guided rockets that deals 50 demage on impact per 57s ( ~ 0.87/dps) with (2x2) space. This building is a powerful defence on mid game. it is specially very strong against single targets. However becosue of rockets slow movement specially on multiple enemies, rocket's target sometimes being destroyed by something else which wastes the 57s refire rate. Or they can target enemies with low hitpoints. That stuation creates a demage leak. You cannot always use this building with its full potential.

 2- SkyShield Missles:   Attacks invaders and asteroids with  10 dmg  per 49s ( ~ 0.2/dps) Fires rockets which follow and boom at target. Same demage leak/waste stuation also happens in this building too. even info says so, this building is not upgradeable currently.

3-  SkyShield  Laser Beams deals 2 dmg per 13s ( ~0.15/dps )  Lasers are instant and one tick of its damage is lower than rockets. So you waste your damage output less than SkyShield Missles. This building is upgradeable with alien metal. (you will need alot) and a fully upgraded laser beam does   5 dmg per 13s  ( ~ 0.38/s)



if we compare all buildings with (2x2) building space (required for Lunar Security)

SkyShield Missles:  ~  0.81 dps (damage will be wasted)

 Lunar Security :  ~  0.87 dps  (damage will be wasted even more)

Sky Shield Laer Beams (pure) :  ~  0.61 dps  (no waste at all)

 SkyShield  Laser Beams (fully upgraded):   ~  1.52 dps (some little damage waste can happen)

 i see alot of maps with many Lunar Security buildings at bottom. Including mine. But i suggest you to build 4x SkyShield Missles instead becouse of demage waste, if you have enough power to supply. Then turn them to 4x Upgraded Laser Beams by time.
