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 standard, though is available in yields from 20 to 90 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, during the battle taking place on the planet, destroying the city and all the Covenant in it.

Trivia

 * Each HAVOK weighs about 5-6 tons.
 * Not likely named after the physics engine Bungie uses, HAVOK. Halo: The Fall of Reach was published in 2003, whereas the HAVOK Physics Engine was not implemented into the series until Halo 2, which was released a year later.
