United Launch Alliance Delta IV heavy lift expendable launch vehicle successfully boosted the last Defense Support Program satellite into orbit Nov. 10 at 8:50 p.m. The Northrop Grumman-built DSP separated from the booster six hours and 20 minutes later, states a company release. Slated to be replaced by the Space-based Infrared System, the DSP constellation should serve “well into the next decade” with the addition of DSP 23, said Alexis Livanos, head of Northrop’s space technology sector. The DSP system has been in service for about 40 years.
Impure metal used to make a gear in the proprotor gearbox of a CV-22 caused it to fail, leading to a mishap and emergency landing in November 2024 that resulted in nearly $2.8 million in damages and a brief operational pause for the entire Osprey fleet, according to a new Air Force report.
