Northrop Developing 6th Gen Fighter Plans

Northrop Grumman has stood a pair of teams dedicated to developing a "sixth-generation" fighter for both the Navy and Air Force, years before the US Navy or Air Force intends to issue requests for information on potential replacements for current aircraft.
Both the Air Force and Navy have begun preliminary planning for what is referred to as next-generation air dominance, or "sixth-generation" fighters. After working together on the F-35 joint strike fighter, the two services are looking at procuring their own respective jets.
The Navy's program is dubbed F/A-XX, while the Air Force's effort is known as F-X.
That program is expected to award a contract to either Northrop or its competitor, a team of Lockheed Martin and Boeing, in late spring or early summer.
