Most of the information is simply taken from the stats panel in the tactical screen with a few bits here and there obtained by testing. Still missing is rate of fire and for many burst/volley fire weapons the number rounds fired per attack.

For upgrades I only listed upgrades which have effects not immediately obvious from the equip screen tool tip.

"...the personification of the Harbinger fleet, our Executors danced through the battlefield like angels of death, felling heretic fighters and capitals alike."

Hull: 100
Shields: 200 (with ENERGY SHIELDS upgrade)
Speed: 149
Boost Speed: 412
Weapons: 1 x Executor Primary, 1 x Executor Secondary, 1 x Executor Heavy

AC-1437 AUTOCANNON
"The AC-1437 AUTOCANNON cannon fires fast-moving kinetics slugs that possess average range and damage characteristics."


Hull Damage: 16
Shield Damage: 4
Range: 3,600 m
Fire Rate: approx. 450 rpm
Capacity: 35 (continuous fire from zero heat).
Reload: 2 seconds
Note: The AUTOCANNON uses a heat system. The weapons continuously cools off and in effect passively "reloads". However using the reload button speeds this up immensely.

M5-LONGRIFLE
"The M5-LONGRIFLE delivers a superheated plasma core to the target, which ignites upon impact and allows the round to penetrate even the heaviest of armor. Useless up close and highly ineffectual versus shields."

Hull Damage: 120
Shield Damage: 2
Range: 12,000 m
Fire Rate: approx. 24 rpm
Capacity: 2
Reload: 5 seconds
Note: The LONGRIFLE fires as fast as you can pull the trigger. Hence the fire rate is mostly limited by the 5 second reload time.

DG-FLC BLUNDERBUSS
"Flechette cannons are imprecise, savage weapons. Magnetically accelerating shrapnel using the vessel's drive engines is both simple and extremely dangerous."


Hull Damage: 12 (240)
Shield Damage: 2 (40)
Range: 1,000 m
Fire Rate: approx. 70 rpm
Capacity: 3
Reload: 2 seconds
Note: Fires 20 flechettes per shot

6B-VII FURY MISSILES
"Also known as the Yellowjacket, the 6B-FURY launcher delivers variable salvos of anti-fighter warheads to the intended target, chopping through shields but struggling against hull. Because of their renowned tracking ability, FURY MISSILES excel at dismantling enemy drones."
Hull Damage: 20
Shield Damage: 75
Range: 1,800 m
Fire Rate: approx. 250 rpm
Capacity: 15
Reload: 2 seconds

4985J ECM-PULSE
"Imperial bounty hunters often equip their vessels with ECM Pulse cannons that disable their targets, preparing them for boarding operations."


Hull Damage: 0
Shield Damage: 50
Range: 5,000 m
Fire Rate: approx. 190 rpm
Capacity: 21 (continuous fire from zero heat).
Reload: 4 seconds
Note: The ECM PULSE uses a heat system. The weapons continuously cools off and in effect passively "reloads". However using the reload button speeds this up immensely.

DKE-SCARAB TORPEDO
"SCARAB TORPEDOES are designed to provide our fighters with situational heavy strike capabilities. They are old technology and are easily countered by point defense systems."

F4-PURIFIER BOMBS

Shield Damage: 10
Range: 2,400 m

Hull: 10
Speed: 600
1 x DR-SL REPAIR PULSE

KAMIKAZE CHASSIS

+2,500 FIGHTER COLLISION DAMAGE
+3,000 DAMAGE PER HEAVY ROUND
Note: This appears to count each bomb so PURIFIER BOMB equipped fighters will gain 6 x 3,000 (18,000) kamikaze damage. This plus the base damage and the 2,500 bonus is enough to
one-hit kill a Traitor Flagship.
