HAVOK tactical nuclear weapon

The HAVOK thermonuclear warhead is mainly used in missiles fired by UNSC Bombers or Cruisers. However, an alternate use is to simply place the warhead on a ground target and detonate it with a remote. Its yield is thirty megatons

Around July of 2552, during the battle of Sigma Octanus IV, Blue Team detonated a HAVOK nuclear warhead at the city of Cote D'Azur, destroying the city and the Covenant in it.
