Last week during the Aerial Firefighting conference there were two interesting aircraft at McClellan Airfield parked in the hangar near the static display of the 747 Supertanker and other firefighting aircraft.
The other aircraft in the same hangar was a Coast Guard C-27J Spartan. A few years ago the U.S. Forest Service attempted to acquire a bunch of the former military aircraft to use them as air tankers. But the Coast Guard intervened, and unloaded seven of their old C-130Hs to the USFS, so they could get the C-27Js.
More information about the C-17J from the Coast Guard, December 18, 2015:
Coast Guard Air Station Sacramento is preparing to become the first permanent home of C-27J Spartan medium range surveillance aircraft, with operations expected to start in 2016.
The HC-27J Asset Project Office will assist with the transition by providing a forward-deployable maintenance team and pilot, aircrew and maintenance technician instructors, said Cmdr. Peter Beavis, APO executive officer. An aircraft to be used for training was repositioned to the air station Dec. 2.
Four aircraft will be transferred to the air station in fiscal year 2016, said Lt. Robert Hovanec, C-27J platform manager with the Office of Aviation Forces. Sacramento will have six aircraft at full capacity, with the remaining two arriving in 2017.
