The C-130H is a mainstay of the United States Coast Guard air fleet.
From The Shield of Freedom, 2006: The Coast Guard's fleet currently includes five HC-130H (1500 series), 22 HC-130H-7 (1700 series), and six HC-130J models of the famous Hercules, widely recognized as the West's premier military transport.
The Coast Guard's history with the "Herc" dates to 1958, when it first ordered the R8V-1G (HC-130B) model, (now retired.) The configuration of these aircraft is suitable for a variety of missions.
The four-engine, high-wing aircraft can carry 92 passengers, although the usual number is 44, with 14 web seats and pallets with 15 airline-style seats each. The HC-130H can also carry 51,000 pounds of cargo, rescue, or oil-pollution-control equipment.
Operated by a crew of seven (7), the HC-130H can airdrop life rafts or dewatering pumps, or dispersant for oil pollution control.
