MSRC’s dispersant program was designed to meet the US Coast Guard planning requirements for tank and non-tank vessels. MSRC’s dispersant aircraft and dispersant stockpiles are staged to meet the time requirements of these regulations. The use of aircraft to spray dispersant allows for a wider coverage area within a shorter period of time than spray systems based on vessels. A C-130 has a larger dispersant payload with a minimum capacity of 4,125 gallons. The C-130 is crewed by three personnel, which includes a Captain, First Officer and Flight Engineer. Other personnel may be required for extended operations. Typical transit speed of the C-130 is 300 knots. The aircraft can stay airborne for a maximum of ten hours, depending on speed and payload. During a typical spray sortie the aircraft descends to 75 feet above the water and slows to approximately 130 to 170 to conduct spray operations.
