Valkyrie type battlestar
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Valkyrie type was deployed alongside a Galactica-type battlestar nearly fifty years before the Fall of the Colonies during the First Cylon War. At the time, they appeared to function as a support vessel in battlestar groups, and not as flagships (Blood and Chrome). In the years since, the type has become a forerunner in the Colonial Fleet, apparently outnumbering the Mercury class and remaining Galactica type battlestars. This type of battlestar is among the smallest ships in service in the post-war fleet, carrying fewer Vipers and Raptors than their larger counterparts. Despite this, their crews are not afraid to tackle threats head on, as three of them were seen attempting to engage Cylon basestars over Caprica before fleet communications went down (TRS: "The Plan").
Measuring over 700 meters long, the Valkyrie type was about half the size of a Galactica-type battlestar. Overall, it shares the common battlestar design, consisting of an "alligator head," mid-section with flight pods attached, and aft the propulsion section, housing the main sublight engines. Possibly because of its smaller size, much of its main layout is exposed or semi-exposed on the underside of the ship, the FTL drive being the most prominent (TRS: "The Plan"). Physically, it was far more "jagged" than other battlestar classes, with sharp edges offset by curved lines. The hull was covered with batteries, missile launchers, and numerous hatches, giving it a sharp and streamlined but functional look.
The flight pods on the Valkyrie type serve the same purpose as with its larger counterparts. However, they are not able to carry as many planes, or allow larger vessels to dock inside, as with the Galactica type or Mercury class. Despite being a Cylon War era design, the flight pods do not retract on this type, not even for FTL jumps.
The hangar deck facilities are smaller, and situated between the flight deck and the Viper launch tubes which run parallel to the pods. Having only three tubes per pod, the Valkyrie type has significantly less launching capabilities than its larger counterparts in the fleet. However, this doesn't preclude them from being assertively deployed, and may suggest a more offensively oriented approach to Viper launches. The tubes are also significantly longer than those of other battlestars. There are three separate points where Vipers could be lowered from the hangar into the tubes. It is possible that this allows for a much higher rate of launch. (TRS: "Hero", "The Plan").
Ships of the Valkyrie type have four sublight engines attached to the ventral side of the ship at the rear. There are also maneuvering thrusters placed in strategic positions along the hull.
The computer systems on the Valkyrie type were presumably non-networked in the early years of service. However, sometime during the forty years since the end of the Cylon War, these systems were upgraded, networked, and thus became accessible through the compromised Command Navigation Program like nearly all other ships in the Colonial Fleet. Thanks to this, the Cylons were able to take control of the battlestar's systems and shut them down before their attack.
Although a small hull (compared to battlestars like Pegasus or Galactica) these ships were heavily used. They type may have served a role similar to cruisers in modern navies, as they are shown being used for a number of missions, including patrols, covert operations, and even planetary protection. The smaller size, mass production, and apparent range of abilities presumably meant that it was perfect for a peacetime fleet, as they would be cheaper to produce than the larger Mercury class or Galactica type. They may also have lacked the ability to produce Vipers, unlike the Mercury class.
