fl ew for the fi rst time on March 9, 2007.
Developmental Testing (DT) with the three
upgraded test aircraft was completed on
August 18, 2008.
The SDD aircraft were formally handed over
to the USAF on December 9, 2008, February 9,
2009 and March 2, 2009. By early 2009, RERP
production plans were reduced to just 49
aircraft, comprising 47 C-5Bs and 2 C-5Cs. The
fi rst production aircraft arrived in Marietta on
August 18, 2009 and C-5M serial 83-1285
made its maiden fl ight following RERP
modifi cations on September 19, 2010. The
aircraft arrived at Dover AFB on November 6.
Prior to delivery the aircraft was fl own to
Stewart ANGB in Newburgh, New York,
where interior restoration was carried out.
That involved the installation of new
insulation, trim panels, environmental
insulation and paint in the cargo and troop
compartments. During operational test and
evaluation (OT&E), which began on October 1,
2009 and concluded in January 2010, the three
test aircraft fl ew 1,333 hours.
Incorporating the RERP modifi cations into
the C-5B typically takes nine to 11 months
per aircraft. Eleven C-5Bs are currentlyDimensions
