Ship weapon
There are two different types of starship weapons: Energy Weapons and Kinetic Weapons. Energy Weapons do equal damage to both a starship's shields and hull. Kinetic Weapons do full damage to a starship's hull but shields have an innate 75% resistance to kinetic weapons, though some types of kinetic weapons have improved shield penetration. Energy and Kinetic weapons both have different damage subtypes — for example, Phaser and Plasma are two types of Energy Weapons.
Different ships will have different resistances to each damage subtype depending on hull plating and engineering modules equipped, if any.
Note: see also Shuttle Weapons.

Firing Arcs[edit  edit source]
A weapon's firing arc is the angle of view, measured in degrees (°), inside which an enemy ship must be located. Targets outside of this arc cannot be fired upon by the weapon; you must turn so that the target is within the firing arc in order to fire. (Note that the firing arc for aftmounted weapons is measured from the rear center, as opposed to the front center for fore weapons.)
You can preview a weapon's firing arc by holding the mouse cursor over that weapon's icon on your action bar. The firing arc only represents the angle at which the weapon can fire; it does not represent its range.
The following table shows the firing arcs of each weapon type in Star Trek Online:
45°  90°  180°  250°  360°  No Arc 

Broadside[edit  edit source]
A vessel that equips Beam Arrays both fore and aft is most effective when firing from the Broadside i.e. either the port or starboard side of the ship. This is because the 250 degree firing arc of beam array weapons means that there is region where the forward and aft firing arcs overlap. As such, a ship can fire both fore and aft weapons at a target within that overlap region. As the ship is effectively moving sideways relative to the 70 degree overlap region on either side of the ship, it is easier to keep a target within the optimal broadside firing arc.
Cruisers are best suited to firing from the broadside, as they lack the maneuverability to use weapons with a narrower firing arc. Cruisers also have more weapon slots than other types of vessel at the same tier, and so can potentially deal more damage from the broadside. In a tier 5 Cruiser it is possible to fire eight beam arrays in a single shot to devastating effect, though this causes an enormous power drain.
Autofire and Firing Priorities[edit  edit source]
You can set your weapons to autofire, by right clicking on the weapon icons of your ship. The icon will have a green outline and the tooltip should now read "Autofire enabled". The order in which you activate autofire also determines the firing priorities for weapons with shared cooldowns. This is especially important for torpedo weapons. In practice this means the weapon you enable autofire on first, will have higher priority over the weapons you selected last.
Spherical Damage Range[edit  edit source]
There are weapons that make a sphere of damage on impact. If otherwise mentionned, the impact affects every enemy currently in the sphere created from the impact point's coordinates. The Advanced Radiant Quantum Torpedo has the highest spherical damage range of all weapons with 10km in diameter.
Firing Cycles[edit  edit source]
Energy weapon cycles can be divided into two parts: firing cycle and recharge cycle. During the firing cycle, weapon deals damage and power is drained from weapon subsystem. On cycle end, there is weapon lockout for 12 seconds during the recharge cycle when no damage or power drain will occur.
Weapon type  Base damage  Shots per cycle  Seconds per cycle  Base DPS 

Beam Array  100  4  5  80 
Dual Beam Bank  128  4  5  102 
Single Cannons  72  4  3  95 
Dual Cannons  86  4  3  115 
Dual Heavy Cannons  173  2  3  115 
Turret  45  4  3  60 
Torpedo launcher firing cycle is affected by global cooldown and type specific recharge time. Firing a Torpedo activates a recharge time (seen in the table below) before it can be used again. It also activates a shared cooldown of 2 seconds for all slotted Torpedoes. These intervals prevent multiple Torpedoes to be fired at the same time (like Energy weapons are used) and bound them to firing in a sequence.
Torpedo type  Recharge time/Reload 

Photon  6 seconds 
Quantum  8 seconds 
Plasma  8 seconds 
Chroniton  10 seconds 
Transphasic  10 seconds 
Tricobalt  30 seconds 
Rapid Reload Transphasic  8 seconds 
Gravimetric Photon  8 seconds 
Elachi Subspace (Tricobalt)  10 seconds 
Quantum Phase  10 seconds 
Crystalline Energy  12 seconds 
Neutronic (Quantum)  15 seconds
