The 'E' variant of this aircraft is upgraded from previous models to have enhanced digital avionics, improved radar, and an upgraded flight control system.

CGAS Detroit was established in 1966 at Selfridge Air National Guard base, Michigan and initially flew three Sikorsky HH-52A Seaguard helicopters with an area of operations encompassing Lakes Ontario, Erie, St. Clair and southern Lake Huron. Since the retirement of the HH-52As in the 1980s, the unit has operated five MH-65D Dolphins. The Dolphin has gone through a series of upgrades since they were first assembled in Grande Prairie, TX, including a change of engines (from Lycoming LTS101-750B-2s to Safran Arriel 2C2-CGs turboshafts) and new navigation systems and "glass" cockpit displays.

Ooops....I almost missed my flight back home.
