Improvised UNSC bomb

This Unidentified UNSC bomb was used to destroy the UNSC base known as Crow's Nest during the Battle of Voi in November 2552. Little is known about the bomb, other than the fact that it has a large blast radius.

Trivia

 * The bomb appears to be non-nuclear. It is likely a thermobaric weapon, which is commonly used to take out enemies in caves or tunnels. Thermobaric bombs generate a lot of air pressure as the result of a fireball effect, which comes from the dispersion of a compound like aluminum oxide or iron oxide. This effect generates a fuel air mixture, and it removes most of the oxygen from the tunnels or caves, causing lungs to collapse. Additionally, the large bomb appears to have smaller charges mounted on its main body casing. It is connected to many smaller bombs throughout Crow's Nest, destroying most of Crow's Nest, except the basement and the motor pool.
 * It appears that these bombs can also be found on the level Sierra 117. After the cutscene where Johnson is thrown into the small room, jump down off the cliff and turn behind (once enemies have been eliminated, or in Theater) towards the gate. Stored within the gate are two more bombs, probably duds.
 * It has been a joke at Bungie about how Miranda, in the original Halo 2 script, was supposed to "weld a thermobaric bomb to the Master Chief's armor" in a deal with the Prophet of Regret. Jason Jones, on the Halo 3 Legendary Edition commentary, said he wanted to put this in Halo 2, and was going to add this to Halo 3. This bomb may be a reference to it, as Miranda is in charge, and the Master Chief has to arm it.
