Battery

Colonial Fleet

On board Colonial warships, a battery is a group of large gun turrets working together or in concert. A battery may consist of any number of gun turrets, usually four (The Captain's Hand).

Ammunition

The large turrets found on Colonial battlestars fire large-caliber flak ammunition (Scattered). These shells are too large to be loaded quickly and efficiently by crew members, and as such are loaded by mechanical hoists (33).

The massive recoil caused by firing these flack rounds make it impossible for the cannon to have a fast rate of fire like the point-defence turrets also found on battlestars.

Firing Solution

When engaging enemy targets over any kind of distance, a firing solution must be obtained. This requires several pieces of information to be input to a battery's fire-control computer, including the target's speed, course, and range; and the firing platform's speed and course- velocity of the shells would be known, and would also be a constant, given that there is no air friction in the vacuum of space. The resulting computation would allow the gun captains to accurately aim their weaponry to such a degree that firing will result in a probable hit.

Operation

As with modern naval cannon, Colonial gun batteries have several modes of operation.

• Salvo Fire: this calls for a battery, or elements of a battery, to fire simultaneously at a single target. (The Captain's Hand)
• Full Attack Mode: a battery's commander (Gun captain, 33) will target and engage targets of oppertunity.

There are likely other modes of operation for these batteries, but none have been explicitly stated on screen.

Limitations

Since their turrets are relatively slow to traverse, a battlestar's main guns would be a poor choice for engaging enemy fighters which are small, fast and extremely maneuverable. They would also be impractical for defending against enemy missile attacks, which would be more suceptible to attack from point defence weapons or Vipers.

The turret's slow rate of fire also means that a single turret, if left to operate alone- either due to damage, power failure or any other events- may not be a very effective method of attack. It is for this very reason that the turrets are grouped in batteries.

Cylon Fleet

Whereas the Colonials prefer artillery-style guns, the Cylons appear to favor chemically-propelled missiles. Their basestars also use large masses of Raiders instead of gun emplacements and appear to have no point defense weaponry.

Centurions cannibalized parts of their Heavy Raider on Kobol in order to create an anti-aircraft missile battery. This was later used to attack a search and rescue mission launched from Galactica (Fragged).
