Notes "The MK-19 practice bomb was used for high-altitude horizontal bombing. The MK-19 had an overall length of 13.06". The diameter at its largest point was 2.62". The fins were 3.67" in length. The main body was made of lead-antimony while the fins were made of steel. The weight, when armed, was approximately 13 lbs-2 oz. The spotting charge was a 10-gauge shotgun shell as the signal (AN MK-4) as explained below. This bomb could be used against armored-deck target boats have a 1/2" armor deck. The maximum altitude at release could not exceed 6,000 feet which was far greater than the altitude of 2,500 feet for both the smaller MK-5 and MK-43 practice bombs. Five bombs could be carried in the MK-43 Bomb Rack and eight could be carried in the MK-47 Bomb Rack." []

"Mk 19 Mods 0 and 1, and BDU-2/B practice bombs are painted black with white markings stenciled on the bomb body. The Mk 4 signal cartridges are unpainted with black markings stenciled on the cartridge case. These bombs are impact fired signal-generating, practice bombs used for training aircrews." []

"The United States Navy uses a series of practice bombs ranging from 3lb to 1000lb. originally these bombs were painted black or, some examples were left unpainted. Modern versions of these bombs will be painted blue in accordance with standard colour coding for practice munitions." []
