Leonid Kurchevsky

In 1916–1918, Kurchevsky headed the design bureau of the Moscow Defense Industry Committee (Конструкторское бюро Московского военно-промышленного комитета, (Konstruktorskoye byuro Moskovskogo voyenno-promyshlennogo komiteta).

In early 1934, they organized Special Projects Commissary Directorate (Управление уполномоченного по специальным работам, Upravleniye upolnomochennogo po spetsial'nym rabotam) especially for Kurchevsky.

In his experiments with recoilless guns, Leonid Kurchevsky strived to cover a wide range of artillery weapons.

In 1937, Kurchevsky was arrested, charged with designing poor weapons systems at the Tukhachevsky Case, and sentenced to death on November 25, 1937.

His gun systems were never used in the Great Patriotic War and all work on recoilless artillery in the USSR was stalled for a long time to come.
