The Medium Fusion Destructive Device, or MFDD, commonly referred to in the UNSC as the "Mike Foxtrot Delta Delta" is a tactical nuclear weapon with a yield of 63 terajoules (approximately 15 kilotons TNT equivalent),^[1] used by the United Nations Space Command. It was manufactured by Misriah Armories.^[2]

An MFDD was used by Noble Team to destroy a CCS-class Battlecruiser during a battle on an unspecified human colony world during the Human-Covenant war.^[3]

TriviaEdit

• The concept art of the MFDD shows framework attached to the underside of the device, while the prop in the trailer has this framework removed. This was for the purpose of making the prop easier to carry around during acting.^[2]
• The MFDD was designed by Bungie's veteran concept artist Isaac Hannaford.^[2]
