It is identical to the BLU-111 with the exception of the amount of PBXN-109 explosive filler
. The aft end of the BLU-126 bomb is packed with approximately 27 pounds of explosive filler
with the remainder of the bomb being filled with inert material.
The main section holding the explosive filler
is threaded at both ends: The fuse assembly forms the third part.
The US Air Force has long been confident of making medium altitude tactical incursions, allowing hard targets to be attacked with more conventional bombs, using penetration warheads with thick forged steel casings and a Tritonal or PBNX-109 explosive filler
. They were initially designated I-500, J-1000, and I-2000 (the numbers indicating approximate weight in pounds), and later BLU-111, -110, and -109 respectively.
In the more serious example, the suspect provided accurate details when describing a basic pipe bomb recipe: pipe, viable explosive filler
, and a fuse to initiate the device, lie shows that he has knowledge to make a device, and it suggests that he put time, energy, and resources into his plan.
The explosive filler
was Octol, a very expensive chemical explosive also used to trigger nuclear weapons, with a detonation rate of over eight thousand meters per second.
