 Boeing plans to offer a solution based on their Boeing 737-700 commercial jetliner airframe; the 737-800 configuration is already in military service with the U.S. Navy as the P-8 Poseidon for maritime surveillance, and would be favored if the Air Force chooses a larger platform.The decision on airframe size may be based on whether the Air Force thinks it can have processing capabilities off-board or if it wants to keep everything on the physical platform.Northrop Grumman has also announced their intention to compete for the future of Joint STARS, although they have not confirmed what airframe they will use.
