There are 3 defense buildings in the game currently.

1- Missles:   Attacks invaders and asteroids with  10 dmg per 49s ( ~ 0.2/s) Fires rockets which follow and boom at target. Because of rockets slow movement, sometimes their target will explode before it arrives. Sometimes they have less health than the rockets damage amount. Even tooltip says various upgrades are available this building is not upgradeable currently.

2- Laser Beams deals 2 dmg per 13s ( ~0.15/s ) But 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)

3- Lunar security this building also fires rockets that deals 50 demage per 57s ( ~ 0.87/s) with (2x2) space they are also slow

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

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

Lunar Security :  ~  0.87 dps  (damage can 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 damage waste can happen)
