Early in 1945, a Blohm & Voss (B&V) aircraft designer called Thieme began work on Drawing Number Ae 607, within the standard drawing numbering system at B&V. His design for a jet fighter was radically different from anything that B&V had done before. A flying wing, it approximated to a 45° delta planform.
Reports of its existence were not confirmed until 2017, when the drawing was published. No Project number is recorded for the design and its intended status is unknown.
