The reliability of SUS signals, underwater sound explosives as acoustic sources is an important consideration when these devices are used in ocean propagation measurements. Records have been kept on the performance of many MK 61-0 SUS, set to fire at 800 ft depth, that have been launched from aircraft over the past several years in a series of propagation experiments. While the majority performed satisfactorily, a significant number detonated well outside of the intended depth range, did not explode, or exhibited abnormally slow sink rates. Partial detonations also occurred, but infrequently. While the observed deficiencies do not render the current stock of SUS useless to the oceanographic community, the reliability of SUS procured in the future for ocean acoustic measurements might be improved by effecting minor design changes.
