California startup  (Long Beach, Calif., U.S.) has unveiled an all-composite blended wing body (BWB) aircraft design targeting the commercial midsize aircraft and defense tanker-transport markets. Known as the Z-5, the aircraft is designed for a range of approximately 5,000 nautical miles and to carry up to 250 passengers.

JetZero hopes to boost the development of its commercial BWB with interest from the U.S. Department of Defense in a prototype for a large-scale advanced tanker-transport aircraft for the U.S. Air Force. According to a recent , JetZero, in partnership with Northrop Grumman (Falls Church, Va., U.S.), has submitted a proposal for the Air Force program in late March, and is preparing for flight tests of a NASA-supported subscale demonstrator. The company claims that because of its fuel efficiency, the Z-5 can carry up to twice the fuel of the Boeing KC-46 tanker.

Featuring a wide single deck and high-aspect-ratio wing, the Z-5’s reduced weight and power requirements will enable the use of derivatives of existing single-aisle engines and conventional fuel tanks, while the BWB configuration affords space for liquid-hydrogen fuel tanks in the future.

The Air Force says it plans to select a winning proposal by midyear with demonstrator flights targeted for 2027. JetZero is targeting the Z-5’s entry into service in the 2030s.
