The Mercury class battlestar is an advanced Colonial capital warship/carrier introduced into the Colonial Fleet sometime after the First Cylon War.


Following the end of the Cylon War, the original battlestars remained in service as other battlestars were built. Their numbers steadily increased to a grand total of 120 ships in the Colonial Fleet. Newer models employed networked computers which had been prohibited during the war. Being networked (and compromised by the Command Navigation Program) allows the Cylons to hack the computer systems, disable them with electronic attacks, and render the ships defenseless (Miniseries).

A Mercury class battlestar sports several features not found aboard Galactica such as automated sliding doorways and basic computer recognition stations at vital areas. At the time of the Fall of the Twelve Colonies, a Mercury class battlestar was a top-of-the-line vessel.

The physical appearance of the Mercury class is different than that of the original battlestar. The "neck" section is smaller, and the Mercury class is equipped with eight sublight engine pods, compared the older class's six. These are also more "boxy" in appearance than those of the original. Unlike Galactica type battlestars, the Mercury class has a full armor "skin." Each flight pod consists of two stacked landing bays with adjoined decks and hangars. Combined with computer assisted landing, this gives the class a faster rate of Viper recovery than previous battlestars.

This, probably the largest of the battlestars, may be able to carry a maximum of 50 Raptors and 200 Viper Mark VII fighters (8 squadrons and two reserve squadrons color coded blue, red, green, yellow, orange, purple, black, white, and reserve squadrons gold and silver) [2].

The gun batteries on the Mercury class are arranged very differently from Galactica's. Whereas the Galactica's type battlestars' twenty-four large guns are clustered along the dorsal and ventral sides, with secondary batteries concentrated along the flight pods, the guns of the Mercury class are found all over the ship (The Captain's Hand). The greatest concentration of large turrets are found along the side of the ship, within the valley created by the upper and lower halves of the hull, including the flight pods. Four are mounted on the underside of the upper hull on the ship's bow, below which sits four non-turreted large guns; these form the main forward batteries. Six turrets are mounted on each underside of the alligator head, grouped in pairs. There are also three turrets on the side of each flight pod along two more turrets are mounted on the front and back of each flight pod. This amounts to a total of thirty-four main gun batteries, ten more than the Galactica type Battlestar. In addition, the turreted guns of the Mercury class have a higher rate of fire than Galactica's turreted guns when operating in flak mode, as evidenced by the skirmish with the Cylon War-era Raiders in Razor.

Comparison of original series battlestar and Mercury class

Based on figures from the episodes "Pegasus" and "Razor", the standard crew complement of a Mercury class battlestar is in excess of 2,500, which is significantly lower than found on a Galactica type battlestar. Despite being larger in size than its preceding ship class, this level of crew appears to make operating battlestars of this class manageable, due to heavy computer automation.

The Mercury class battlestar has production facilities to build new Viper Mark VIIs from basic resources (Scar).

Unlike Galactica type battlestar, which must retract their flight pods to execute an FTL jump, the Mercury class' flight pods are fixed in place and do not retract during a jump (The Captain's Hand). This suggests that its jump system is more advanced than the older battlestars's.

Known Mercury class battlestars


The shape of the Mercury class resembles the Original Series battlestar more than the Re-imagined Series' Galactica. Its engine pods number eight, compared to Galactica's six engine pods. The pods aboard the Mercury class battlestar appear more directly integrated with its rear section, and its flight pods share the original angular shape.

The visual effects artist of the re-imagined Pegasus, Jose A. Perez, has commented that, "The new design was somewhat of a cross between the look of the old class battlestars, and yet with elements of the new one. Aside from that, it has mostly hull plating (to absorb more damage) , as opposed to the Galactica which has more ribbing." Mr. Perez also commented that, "The harder edges [ of the Pegasus ] were intentional as well, to match the interior style of the sets more."
