The Air Force has declared the newest Global Positioning System satellite to be fully operational, according to a Dec. 19 statement from prime contractor Lockheed Martin. Air Force Space Command operators shepherded launch of the GPS IIR-16M satellite from Cape Canaveral AFS, Fla., last month. It is part of Lockheed’s eight-satellite Block IIR-M series. On-orbit, it joined two other Block IIR-M satellites and 12 original IIR satellites, according to Lockheed.
F-35As from the Vermont Air National Guard have deployed to Puerto Rico in recent days, continuing a major buildup of U.S. Air Force assets in Latin America aimed at combating drug trafficking and pressuring the regime of Venezuelan leader Nicolas Maduro.
