Backs and sides are open with sections stabilized by sway braces
. Units utilize Hi-Performance[R] shelves with box posts at the front and offset angle posts at the rear.
We learned from the combat loads at AIR WARRIOR that the CBU-87 has a larger diameter and shape, which creates a different relationship between the bomb lugs, sway braces
, and sensor switches.
