Blohm & Voss made its mark for World War 2 Germany as a large flying boat maker. However, its engineers were hard at work in selling the Luftwaffe on various cutting edge - if sometime unorthodox - designs. The P.207 was one of the submissions passed on to the Air Ministry for consideration and was developed against the concept of a single-seat, conventionally-powered fighter.

The P.207 was given a stout, deep fuselage with the single-seat cockpit aft of a rounded nosecone assembly and under a lightly-framed canopy. The fuselage (showcasing a trapezoidal appearance from the forward profile) was well-tapered at both ends with a cruciform-style tailplane used at rear. The nose assembly would house the four-cannon armament comprising 2 x 30mm MK 103 seated over 2 x 20mm MG 151/20 weapons. This was made possible by the rear placement of the propeller unit, arranged as a "pusher", positioned aft of the tailplanes. The engine itself was installed aft of the cockpit and a drive shaft used help to deliver power to the propeller. An air intake was set aft of the chin running under the cockpit floor. The wing mainplanes were installed low at midships and were straight in their general appearance with a slight rounding of the tips. The mainplanes were to exhibit some dihedral. A wheeled tricycle undercarriage completed the list of features and gave the P.207 a rather tall stance when ground-running.

Power was to come from either a Junkers Jumo 213 series engine of 1,800 horsepower or an Argus As 413 engine of possible 4,000 horsepower output. The As 413 was to be based on the earlier As 412 which was prototyped as a 24-cylinder H-block engine but the As 413 itself was never built. On the other hand, the Jumo 213 saw some 9,000 production units built during its run and powered such types as the Junkers Ju 188 fast reconnaissance platform and the class Focke-Wulf Fw 190 fighter (both detailed elsewhere on this site). It was developed from the successful Jumo 211 V-12 series which saw nearly 70,000 units made.

As no test subjects of the P.207 were completed, there are no specifications available. Its wingspan is estimated to be around 39.5 feet. Drawings indicate a seemingly adequate fighter save for the rear placement of the propeller unit competing with the ventral rudder fin. This would have posed an issue during take-off and landing actions. The raised dorsal spine behind the cockpit would also have limited views to the rear.

A revision of the core P.207 (P.207.02) design was the P.207.03. The single-seat, single-engine (pusher) arrangement remained but a bubble canopy was added and the tail planes reworked (the dorsal fin was deleted and the ventral appendage made larger). The wing mainplanes were now tapered toward the tips and the chin airscoop moved much further aft in the design. Wingspan was 32.6 feet with an overall length of 32 feet. Power was to come from a Daimler-Benz DB603G series engine of 2,000 horsepower. Proposed armament was 4 x 30mm MK 108 cannons.
