Mass of weapons and ship components

To calculate the exact empty mass of a ship the the used beam weapons and torpedo launchers are added to the hull mass of a ship design.

Note that neither engines nor fighter bays have their own mass, since they are integrated in the hull mass during the construction process.

Beam Weapons Mass Torpedo launchers Mass
Laser 1 kt Mark 1 Photon 2 kt
X-Ray Laser 1 kt Proton Torpedo 2 kt
Plasma Bolt 2 kt Mark 2 Photon 2 kt
Blaster 4 kt Gamma Bomb 4 kt
Positron Beam 3 kt Mark 3 Photon 2 kt
Disruptor 4 kt Mark 4 Photon 2 kt
Heavy Blaster 7 kt Mark 5 Photon 3 kt
Phaser 5 kt Mark 6 Photon 2 kt
Heavy Disruptor 7 kt Mark 7 Photon 3 kt
Heavy Phaser 6 kt Mark 8 Photon 3 kt

The table shows the mass for one beam weapon, respectively one torpedo launcher.
Should a ship design for example have 4 beam weapons installed, the beam mass must be taken x4.
