Chemical Automatics Design Bureau (CADB), also KB Khimavtomatika (Russian: Конструкторское бюро химавтоматики, КБХА, KBKhA), is a Russian design bureau founded by the NKAP (People's Commissariat of the Aircraft Industry) in 1941 and led by Semyon Kosberg until his death in 1965. Its origin dates back to a 1940 Moscow carburetor factory, evacuated to Berdsk in 1941, and then relocated to Voronezh city in 1945, where it now operates. Originally designated OKB-296 and tasked to develop fuel equipment for aviation engines, it was redesignated OKB-154 in 1946.

In 1965 A.D. Konopatov took over leadership. He was succeeded by V.S. Rachuk in 1993, then by Victor D. Gorokhov (RD-0124 Chief designer) in 2015. During this time the company designed a wide range of high technology products, including liquid propellant rocket engines, a nuclear reactor for space use, the first Soviet laser with an output of 1 MW and the USSR's only operational nuclear rocket engine. The company has designed more than 60 liquid propellant engines with some 30 having entered production.

KB Khimavtomatika's original mandate was to develop aviation fuel systems for Soviet military during World War II. Kosberg had spent ten years working at the Central Institute of Aircraft Engine Construction on fuel systems and was tapped to run the new bureau. Approaching German armies required the group to relocate to Berdsk, Siberia, where Kosberg and his team of about 30 specialists developed direct injection fuel systems, eventually implemented on the La-5, La-7, Tupolev Tu-2 and Tu-2D. The new fuel systems provided a significant increase in performance over conventional gasoline fuel systems and eliminated carburetor float problems caused by aggressive combat flying. They competed with direct injection systems developed by Daimler Benz at the time. After the end of the war, the design bureau was moved to Voronezh, where it continued to design fuel systems for piston, turboprop and jet aircraft.
