This from Defense Industry Daily,
Lockheed Martin has delivered the first of eight C-130J-30 Super Hercules aircraft to the Youngstown Air Reserve Station in Ohio as part of a project to modernize the installation’s aging military transport fleet. The plane incorporates a new configuration of aerial spray capability to secure large areas from disease-carrying insects and other pests as well as to disperse oil spills in water surface domains. Lockheed wrote that this function marks the 19th unique mission feature of the C-130J product line. (Emphasis Applied–Chuck)
Usually, we try to recover oil at spills, but using fixed wing aircraft to disperse oil spills might be a capability the Coast Guard could use, either organically or by tapping other service resources.
