Starting in 2009, Coast Guard Jayhawks have been tasked with a secondary mission of drug patrol/enforcement. These missions are usually conducted in cooperation with coast guard cutters.
In 2016, some Jayhawks were delivered in a yellow color scheme celebrating 100 years of Coast Guard aviation. The yellow color scheme represented colors used on certain Coast Guard and Navy helicopters in the 1940s and 1950s. The first of the operational aircraft in this color scheme was delivered to Air Station Astoria in Oregon on January 15, 2016. The Jayhawk along with the Eurocopter MH-65 Dolphin are the two helicopter types in the Coast Guard inventory.
