Class-D nuclear warheads are a type of nuclear weapon used by battlestars and their Viper squadrons.

After news of the Cylon attack on the Twelve Colonies and the Colonial Fleet, Commander Adama orders a desperate search through Fleet database records for munitions depots to rearm Galactica as its own munitions had been destroyed as part of her scheduled decommissioning.

Little else is noted about the weapons, except that Colonel Tigh's records indicate that 50 pallets of these warheads are kept at Ragnar Anchorage along with missiles and small arms ammunition (TRS: "Miniseries, Night 1").

Use of Colonial nuclear weapons

Insufficient information exists as to whether the other nuclear warheads seen through the series are also Class-D or of some other type. It is probable, but not verifiable, that Pegasus gave some of these weapons to Galactica, when the two battlestars pooled their resources.


  • In the United States military, Class-D is the designation of a relatively light-weight thermonuclear weapon. The W-28 warhead in the B-28 TN bomb is an example of this type.
