Lockheed Martin has delivered its eight and final new Global Positioning System satellite in the Block IIR production program. A company release states that there currently are three IIR-M satellites on orbit, along with 12 of the original Block IIR spacecraft. The Air Force plans to launch the fourth Lockheed-built GPS IIR-M, with enhanced operations and navigation signal performance, late this year.
