History of Blohm and Voss Bv p. 197

Mid-1944 proved to be a turning point for the Germans in World War II (1939-1945). The Allies made steady progress in the Italian campaign on the vast eastern front and now managed to gain a foothold in northern France on their way to Berlin via Paris.

Ultimately, it was decided to focus on controlling the effects of the Allied bombing campaign, which wreaked havoc day and night on every aspect of the German war machine and its people.

One of the main needs of the Luftwaffe was a high-speed, high-altitude interceptor capable of defending against the threat posed by Allied bombers. As the profitability of turbojet technology continues to increase, a new generation of Luftwaffe aircraft can demonstrate unprecedented performance, surpassing any aircraft available to the Allies.

In the summer of 1944, German authorities established requirements for such an aircraft, which included a single-pilot design, powered by twin-turbojet engines, and capable of flying at high altitudes against the bomber threat.

According to the draft, the aircraft has a barrel length of 29.5 feet and a wingspan of 36.4 feet. Estimated total weight is 12,855 pounds.

The end result was an elegant fighter jet design that represented one of the cleanest "paper planes" of the war, and due to its inherent performance and small size, would be one of the fastest aircraft in service in Germany. The draft was ready in August 1944.

Performance estimates include a top speed of 620 to 660 mph with a service cap of just over 40,000 feet (requires cockpit pressurization and ejection seat system). The rate of climb is optimistic at 5,000 feet per minute (at best, a classic Me262 can reach 3,900 feet per minute with two Jumo 004 engines).

The proposed weapon is an impressive 4 x 30mm MK-103 automatic cannon, all nose mounted to concentrate fire. This arrangement was enough to take down an Allied heavy bomber with a single fire. However, the size of the projectile will limit the ammunition depot on the ship.

Another weapon scheme consists of 2 x 30mm Mk 103 cannons and 2 x 20mm MG151/20 cannons in the nose.

Nonetheless, the P. 197 turned out to be nothing, as the German authorities showed little interest in this impressive Blohm & Voss design.
