The primary spray aircraft, all delivered in the late 1980s and early 1990s, feature upgraded electrical connections,

paratroop doors with a sealable port that accommodates the four-inch diameter pipe for the spray nozzles, and

internal plumbing for an inner and outer set of spray bars mounted under each wing. “The spray bars give us extra

coverage per pass, but they are not used on most missions,” notes Townsend. “We mainly use the door nozzles.” The

nozzles and spray bars are installed on the aircraft after arrival at a deployed location.
