Battery

From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide

On Colonial warships, a battery is a group of guns or missile launchers operated together at one place. A battery may vary in number and arrangement depending on class ^[1].

Galactica type battlestars are armed with 24 gun turrets, with two gun barrels each. Eight are mounted on the dorsal and sixteen on the ventral hull. Of these sixteen, eight are mounted on the bow and are thus able to fire directly forwards. It is likely that the term "battery" refers to several of these turrets acting in concert. One of the forward dorsal turrets is destroyed either during the liberation of New Caprica or the Battle of the Ionian Nebula (He That Believeth In Me) ^[2].

On Mercury class battlestars, on the other hand, four forward guns are grouped to a battery (The Captain's Hand) ^[3]. In addition, many smaller, 2-barelled turrets are located along the sides of the flight pods. Unlike Galactica's rapid-fire point defense guns, these have a slower rate of fire and are also used for offensive action ("Pegasus", "Exodus, Part II").

• In modern day naval nomenclature, a vessel's "main battery" is its primary offensive weapon. Since the battery of four two-barreled gun turrets at the bow of Pegasus has been referred to as such on several occasions, it is likely that this battery - presenting the battlestar's smallest profile to the enemy - is used primarily for offensive actions, while the others could be adapted for use as per mission parameters.

Ammunition

The large turrets found on Colonial battlestars fire several types of ammunition, depending on the objective:

• Flak ammunition: this ammunition employs exploding metal fragments at high velocity, creating a defensive barrier around the battlestar which can shear enemy fighters or incoming missiles. This, along with the point-defenses, keep the enemy at a distance, allowing the battlestar's Viper forces to safely deploy and engage (Scattered).

• Offensive ammunition: in this configuration, salvos from the main cannons are extremely lethal to the unarmored Cylons basestars, which furthermore posess no such weapons or point-defense themselves. As such, this is a battlestar's main weapon against other capital ships ("Resurrection Ship, Part II", "Exodus, Part II").

It should be noted that the massive recoil caused by firing these flak rounds makes it impossible for the cannon to have a fast rate of fire like the battlestar's point-defense turrets. These shells are also too large to be loaded quickly and efficiently by crew members, and as such are loaded by mechanical hoists (33).

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. The velocity of the shells would be known, and is 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

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, called gun captain ("33", "You Can't Go Home Again"), will target and engage targets of opportunity ^[4].

On Mercury-class battlestars, gun batteries can be set to one of several automatic firing modes (Exodus, Part II). It is unknown if the gun batteries on older battlestars have this capability as well. There are likely other modes of operation for these batteries, but none have been explicitly stated on screen.

At least on Galactica-type battlestars, the turrets appear to be manned and manually fired.
