Shiva-class nuclear missile

The Shiva-class nuclear warhead is a United Nations Space Command weapon.

It is a ship-mounted nuclear weapon used by UNSC capital ships. It can also be fitted on a Longsword interceptors for a low-profile insertion. They can be fitted with guidance computers for increased accuracy. It should be noted that Covenant capital ship shields have enough power to absorb a full nuclear blast far away but not directly, but if the warhead detonates inside the shield, the effect of the blast is multiplied tremendously.
