The first of two upgraded C-5M-SCM Super Galaxy aircraft specifically modified to transport NASA space containers was recently tested to make sure the aircraft met NASA requirements, according to an Oct. 13 release. Officials with Lockheed Martin and Travis AFB, Calif., collected in-flight noise and vibration data by strategically placing 12 microphones throughout the aircraft’s specially modified cargo compartment. The aircraft has been retrofitted with General Electric CF6-80C2 engines as part of the C-5M Reliability Enhancement and Re-Engining Program (RERP). Air Force Space Command requested the test because the new engines provide “22 percent greater takeoff thrust, potentially altering the vibrations generated within the cargo compartment,” states the release. The average clearance between the Space Container Transportation System and the modified aircraft is about one? inch, “leaving little wiggle room should the cargo shift within flight.” NASA is currently analyzing the data to verify the aircraft’s compliance. The second C-5M-SCM is undergoing RERP and is slated to return to Travis in late 2017, states the release.
The Air Force and Boeing agreed to a nearly $2.4 billion contract for a new lot of KC-46 aerial tankers on Nov. 21. The deal, announced by the Pentagon, is for 15 new aircraft in Lot 11 at a cost of $2.389 billion—some $159 million per tail.
