Lockheed Martin announced that it successfully completed thermal vacuum testing of the Air Force’s second Space Based Infrared System geosynchronous satellite, moving it one step closer to its launch into orbit next year. During the testing, the company exposed the satellite, which is designated GEO-2, to extreme hot and cold temperatures, like those it will experience on orbit, in order to verify functionality and performance. Thermal vacuum testing was the last of several environmental evaluations to ensure the spacecraft’s overall design, quality, and survivability. “With the completion of environmental testing on GEO-2, the government and industry team is well positioned to deliver this vital spacecraft for launch,” said Dave Sheridan, Lockheed SBIRS deputy program director. In August, Lockheed announced the completion of GEO-2’s acoustic testing. Next up are integrated spacecraft and system tests before GEO-2 ships to Cape Canaveral AFS, Fla., for mating with its launch vehicle and subsequent shot into space.
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.
