The MG 151/20 anti-aircraft triple mount (designated Fla-L 151 D/B) was a light anti-aircraft weapon developed by the German Wehrmacht starting in 1944; it combined three MG 151/20 autocannons—originally designed for aircraft—onto a single rotating mount. This development was driven by the growing need for effective weapons to counter low-flying Allied aircraft. The system could be deployed in a stationary role or mounted on various vehicles and trailers; the most well-known production version was installed on the Sd.Kfz. 251/21.

Each of the three 20 mm cannons had a rate of fire of approximately 700 rounds per minute, giving the triple mount a theoretical combined rate of fire exceeding 2,000 rounds per minute. The belt-fed ammunition system—utilizing a 450-round belt for the center gun and 240-round belts for each of the outer guns—allowed for significantly longer bursts of fire compared to the magazine-fed 2 cm Flak 38. The 20×82 mm*Minengeschoss (high-capacity explosive shell) ammunition was particularly effective, valued for its high explosive impact against aircraft and unarmored ground targets. The mount offered a 360° traverse and an elevation range of -3° to +49°, and was operated by a three-man crew using simple ring or floating-circle sights.

Although the Fla-L 151 D/B was among the most capable light anti-aircraft weapons in the Wehrmacht's arsenal, it saw service in only limited numbers during the final months of the war. In addition to its standard installation on the Sd.Kfz. ... Contemporary photographs also document improvised mountings of the 251/21 on trucks, tank chassis, and trailers. However, due to its late introduction, the weapon could no longer exert any significant influence on the course of the war and remained a technically interesting but rare development in German armaments during the final stages of the conflict.
