337th AS train to fly the C-5M Published March 16, 2017 By by Senior Airman Monica Ricci 439th Airlift Wing WESTOVER AIR RESERVE BASE, Mass. -- The nest is still empty at Westover, but come summertime, our birds are expected to start making their way home.It’ll take some getting used to. The familiar whine of the C-5B Galaxy’s engines that has saturated the air at Westover for decades will be reduced to a much quieter hum when the first of eight C-5M Super Galaxies returns in June.With the new C-5M, comes key upgrades: off-the-shelf engines, LED lighting, and improved electrical, hydraulic and fuel systems are just a few of many.If you ask the flight crews what they’re most excited about, however, it’s the reliability the rejuvenated aircraft promises. In the C-5B’s absence, the base has received five C-5A “loaners” to keep Westover’s mission moving.“We’ve gone down from 16 aircraft to eight, and now to five with the A models,” said Lt. Col. Tim Robinson, operations officer from the 337th Airlift Squadron. “Training has suffered, we’ve had to cancel multiple locals [training missions].”In preparation for the big return, a cadre of pilots, engineers and loadmasters are headed to Dover Air Force Base, Delaware to get spun up on all things C-5M. Once they’re done, they’ll return and train the rest of Westover’s crews.The base will also be receiving a brand new C-5M simulator to replace the current C-5B simulator as early as March. Robinson said simulators provide a more cost-efficient way for pilots to train, and provide a platform for pilots to practice emergency situations they otherwise wouldn’t be able to in the air.
