Cast Ductile Iron Practice Bombs

Practice Bombs

Full scale inert practice bombs which simulate the ballistic properties of tactical General Purpose Bombs used by the Air Force and Navy.


BDU-50 (500lb) Bomb

The BDU-50 is a 500lb. practice bomb, an inert version of the MK82. This inert “heavyweight” bomb is dropped either with a parachute for “High Drag” or “Slick”, which has no drag device. Delivery of a BDU-50 High Drag Bomb from a low altitude, low dive angle results in the bomb impacting at or near the target and has very little or no ricochet, due to the aerodynamic effect of the high drag retard device. However, when the high drag system fails to deploy, the weapon takes on the characteristics of a low drag weapon and has a significantly increased slant range to impact (up to 4,000 ft longer under certain conditions). The bomb is manufactured as a forged configuration and manufactured as a cast ductile iron configuration.


BDU-56 (2000lb) Bomb

The BDU-56 is a 2000lb. practice bomb, an inert version of the MK84. This inert “heavyweight” bomb is dropped either with a parachute for “High Drag” or “Slick”, which has no drag device. Delivery of a BDU-56 High Drag Bomb from a low altitude, low dive angle results in the bomb impacting at or near the target and has very little or no ricochet, due to the aerodynamic effect of the high drag retard device. However, when the high drag system fails to deploy, the weapon takes on the characteristics of a low drag weapon and has a significantly increased slant range to impact (up to 4,000 ft longer under certain conditions). The bomb is manufactured as a cast ductile iron configuration.


BDU-61 (1000lb) Bomb

The BDU-61 is a 1000lb practice bomb, an inert version of the MK83. This inert "heavyweight" bomb is dropped either with a parachute for "High Drag" or "Slick", which has no drag device. Delivery of a BDU-61 High Drag Bomb from a low altitude, low dive angle results in the bomb impacting at or near the target and has very little or no ricochet, due to the aerodynamic effect of the high drag retard device.
