Octanitrocubane is a powerful high explosive compound. The United Nations Space Command makes use of octanitrocubane shaped charges, commonly known as octas,[1] with a yield equivalent to one hundred kilotons.[2]
Description
Octas are tubs of high-yield explosive that cost more than a HAVOK tactical nuclear weapon to produce. Despite this, they are considered worth making as they are shaped charges and their explosive yield does not decrease in a vacuum.[3] Octas have a yield equivalent to one hundred kilotons of TNT[2] and run on timed fuses. Additionally, octas have a sixty-minute automatic countdown that can be activated. This acts as a failsafe in case the person carrying the octa is killed or the octa falls into enemy hands. If an override code is not entered before the countdown ends, the octa will detonate on its own.[4]
Octadarts are a kind of explosive ordnance used by GA-TL1 Longswords. These relatively small laser-guided bombs make use of octanitrocubane charges powerful enough to blast through a warship's energy shields.[5]
History
In April 2526, during Operation: SILENT STORM, the Spartan-IIs and Orbital Drop Shock Troopers of the Black Daggers armed themselves with octas alongside HAVOK tactical nuclear weapons for an attack on the Covenant planet of Zhoist and the Ring of Mighty Abundance. During the mission, the Spartans and Black Daggers of Blue and Green Teams planted octas throughout the facilities of the Ring they passed through, destroying each facility.[6]
During the battle, eight of Green Team's Black Daggers were picked up by ships of the Fleet of Inexorable Obedience. The Black Daggers managed to sneak their octas onboard with them when they were captured, running on the sixty minute automatic countdown and as a result, only laughed in the faces of their captors when interrogated. When the timer ran out, the eight octas detonated, visibly destroying the six Covenant ships they went off on to the astonishment of the watching UNSC forces from their hidden Prowlers who realized what the Black Daggers must've done even after being defeated.[7] The Fleet of Inexorable Obedience was decimated by the attack.[8]
By October 2559, the UNSC had weapons called Octadarts which are relatively small laser-guided bombs filled with an octanitrocubane charges capable of simply blasting through the shields of an intrusion corvette.[9]
