MD的NGAD(Next Generation Air Dominance)进展到什么程 ...

Next Generation Air Dominance[1] is a development and acquisition program for a future sixth generation air superiority fighter to replace the US Navy’s F/A-18E/F Super Hornet beginning in 2025. It is planned to incorporate sixth generation stealth capability. The aircraft is to be operated with or without a pilot, depending on the role. The new fighter is to perform strike, air superiority, ground support, precision bombing and reconnaissance roles.[2] Only Boeing is known to have interest in the program though Northrop Grumman is known to be developing a carrier-based aircraft known as the X-47B. A 1/16 scale model shown at the Navy League Sea Air Space Exposition 2010 shows a 'Flying wing' design with no vertical tails and twin engines.[2]

In late 2011, the Navy plans to analyze alternatives for the NGAD program with a technology demonstration phase beginning in 2013.[1] One of the alternatives being considered is the Lockheed Martin F-35 Lightning II, which would double the Navy's purchase of that aircraft.[3]
