The faulty fuzes led to multiple mishaps where a bomb would detonate within several feet of the aircraft after being jettisoned, destroying the entire aircraft and crew.

 Italian aviators were the first to use bombs in a warfare capacity in 1912 during their campaign of Tripoli. These first bombs were conversions of existing cannon ammunition and were effective only against personnel as they did not provide a strong enough provision to damage hardened equipment or structures. As lifting capacity of aircraft increased, so did the ability for them to carry more and larger explosives.
-For the United States, bomb design did not become a priority until the middle of 1917 when a French official came to the U.S. with several samples of the Gros Andreau bombs which the French were using in large quantities at that time. Immediately these bombs were accepted by the U.S. and used as a standard in developing the first three sizes to be implemented in the military. These three bombs were known as the early "Mark" series, 25 lb Mk.I demolition bomb, 50 lb Mk.I demolition bomb and the 100 lb Mk.I demolition bomb. By December 1917, only six months later, the military put forth requirements for the development of bombs larger than the existing 100 lb bomb. After two more months of development, production of demolition bombs up to 1,000 lbs was started. Rejected 3-inch artillery rounds were the basis for early 25 lb bombs which were modified into a streamlined shape, very similar to the British Cooper bombs of the time. Larger bombs were manufactured and filled with explosive filler, all of which were placed into a streamlined body, of which a cylindrical shape was the most advantageous.

Larger bombs were manufactured and filled with explosive filler, all of which were placed into a streamlined body, of which a cylindrical shape was the most advantageous.
 Early on, the Mark series of bombs proved to be largely unsatisfactory in a number of different areas. The bomb body itself was weak due to the sheet metal it was made from and the number of welds needed to join the pieces together. The stabilizing fins were made of flimsy metal which tended to distort during both the handling and flight of the bomb, adversely affecting accuracy. For the field technicians, inserting the fuse was a complicated process which required removing the stabilizing fin structure potentially damaging the fins. The fuses tended to have a high fail rate and due to their design, they would instantly arm after release from the aircraft posing a direct to the delivery aircraft. Later modifications would eliminate many of the negative factors to include adding a nose fuse, time delaying arming of the fuse, strengthening of the stabilizing fins and adding primer detonators to ensure proper explosive train sequences. Other changes including streamlining all bomb bodies and utilising 100% T.N.T. as an explosive filler resulted in the newer "Modified Mark" series of Army bombs.
