nal Research Council recently released a study concluding that adding “winglets,” those near-vertical wing tip extensions, to most cargo aircraft could save the Air Force millions of dollars in fuel costs, reports Stars and Stripes. The Air Force’s newest airlifter, the C-17 has winglets, but the NRC recommended more research to see if modifying them slightly would enhance fuel savings. It recommended adding winglets to KC-135 and KC-10 tankers and to the C-5 airlifter.
Weeks after senior Air Force leaders revealed the service would shed a number of the re-optimization initiatives pursued by their predecessors, Chief of Space Operations Gen. Chance Saltzman confirmed the Space Force is retaining all of the space-specific elements of the strategy.
