Question: Which lab did one of the inventors of a type of rocket artillery first built and fielded by the Soviet Union in World War II work at?
Context: Ivan Ustinovich Kharchenko (Ukrainian: Іван Устинович Харченко , 23 September 1918 - 1 July 1989) was a Soviet Army Military engineering Colonel and Hero of the Soviet Union.  During World War II, he was a platoon commander.  Kharchenko received was promoted to Junior lieutenant in 1939, lieutenant in 1943 and senior lieutenant in 1944.  He reportedly personally defused more than 50,000 explosives, including bombs, mines and shells.  For his actions in defusing explosives, Kharchenko was named a Hero of the Soviet Union and awarded the Gold Star and Order of Lenin on 2 November 1944.  In the citation for the Hero of the Soviet Union award, it was stated that Kharchenko personally defused more than 1500 bombs weighing more than 500 kilograms each and 25,000 other explosive objects.  After World War II, Kharchenko continued his military service until retirement in 1964.  Until 1956 he was personally engaged in rendering innocuous explosive items left over from World War II. The Wurfrahmen 40 ("launch frame 40") was a German World War II multiple rocket launcher.  It combined a vehicle such as the SdKfz 251 halftrack or captured ex-French Renault UE Chenillette with rocket artillery to form a more mobile and protected artillery piece than the towed Nebelwerfer.  It was nicknamed "Stuka zu Fuss" ("Stuka on Foot" or "Walking Stuka") and "Heulende Kuh" ("Bellowing Cow"). At the conclusion of World War II the Allied nations began the process of disarmament of Axis controlled regions.  Japan occupied Korea at this time and had been in control since 1910.  In 1945, the decision was made to have American Marines forces oversee Japanese surrender and disarmament south of the 38th parallel and the Soviet Union would facilitate the change of power to the north.  At the time there was no political motivation and seemed to be a logical and convenient plan of action.  The original agreement and intent was to create a unified and independent Korea out of the post Japanese occupation era.  Instead each side of the 38th parallel established its own government under the influence of the occupational country; the United States in South Korea and the Soviet Union in North Korea.  Both new Korean governments discredited the other and claimed to be the only legitimate political system.  Tensions between the North and South escalated and each side began to petition foreign powers for resources and support.  South Korea wanted weapons and supplies from Truman and the United States government while North Korea sought help from Stalin and the Soviet Union.  The United States was still war weary from the disruptive World War II campaign and refused South Korea's request for weapons and troops.  North Korea convinced the Soviet Union to supply them with the weapons and support they requested.  This decision coincided with the United States withdrawing the last remaining combat troops from South Korea.  North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War. The Wind-class icebreakers were a line of diesel electric-powered icebreakers in service with the United States Navy, United States Coast Guard, Royal Canadian Navy, Canadian Coast Guard and Soviet Navy from 1944 through the late 1970s.  They were very effective ships: all except "Eastwind" served at least thirty years, and "Northwind" served in the USCG continuously for forty-four years.  Considered the most technologically advanced icebreakers in the world when first built, the Wind-class icebreakers were also heavily armed; the first operator of the class was the United States Coast Guard, which used the vessels for much-needed coastal patrol off Greenland during World War II.  Three of the vessels of the class, "Westwind", "Southwind", and the first "Northwind" all went on to serve temporarily for the Soviet Union under the Lend-Lease program, while two others were built for the United States Navy and another was built for the Royal Canadian Navy; all eight vessels were eventually transferred to the United States Coast Guard and the Canadian Coast Guard. The 78th Field Artillery Regiment is a field artillery regiment of the United States Army.  Initially activated on 1 July 1916, the 78th Field Artillery Battalion did not see action in World War I, but would later be reactivated at the start of World War II and participate in the campaigns for Algeria-French Morocco, Sicily, Normandy, Northern France, Ardennes-Alsace, Central Europe, and the Rhineland with the 2d Armored Division.  The 78th Artillery Battalion's six batteries were reorganized into separate battalions in 1957, with the 1st Battalion, 78th Field Artillery being the only remaining active unit of the 78th Field Artillery.  The 1st Battalion, 78th Field Artillery is assigned to the 428th Field Artillery Brigade, supporting the Fires Center of Excellence mission through the conduct of Initial Entry Training in order to provide the Army with combat ready Field Artillery Soldiers.  The 1st Battalion, 78th Field Artillery conducts Advanced Individual Training for the 13-series (Field Artillery) Military Occupational Specialties (MOS) of 13B (Cannon Crewmember), 13F (Joint Fire Support Specialist), 13J (Field Artillery Automated Tactical Data System Specialist), 13M (Multiple Launch Rocket System Crewmember), and 13R (Firefinder Radar Operator). The Katyusha multiple rocket launcher (Russian: Катю́ша ; ] ) is a type of rocket artillery first built and fielded by the Soviet Union in World War II.  Multiple rocket launchers such as these deliver explosives to a target area more quickly than conventional artillery, but with lower accuracy and requiring a longer time to reload.  They are fragile compared to artillery guns, but are inexpensive, easy to produce, and usable on any chassis.  The Katyushas of World War II, the first self-propelled artillery mass-produced by the Soviet Union, were usually mounted on ordinary trucks.  This mobility gave the Katyusha, and other self-propelled artillery, another advantage: being able to deliver a large blow all at once, and then move before being located and attacked with counter-battery fire. Kurt Wilhelm Albert Karl Agricola (15 August 1889 – 27 December 1955) was a general in the Wehrmacht of Nazi Germany during World War II who held senior level occupational rear-security commands in the occupied Soviet Union.  A native of Saxony, Agricola entered army service in 1908 and served during World War I.  During the interwar era, he held staff assignments and continued to rise through the army's ranks in the Wehrmacht of Nazi Germany.  His career ended stalled in January 1939, when he was sent into retirement on political grounds because of his marriage to Martha born Hahn, a Jewish woman.  Reactivated again upon the start of World War II, Agricola received exclusively positions behind the front line.  As rear area commander of the 2nd Army in the occupied Soviet union during 1941–43, Agricola brought changes in the Wehrmacht's harsh occupation policies and was successful in maintaining control of his area of occupied territory from Soviet partisans.  Shortly after the war's end, he was arrested by Soviet authorities, convicted of war crimes and remained in captivity for a decade.  One of the last German prisoners in the Soviet Union, he was released in October 1955 and died shortly thereafter in West Germany. Soviet rocketry spanned the entire history of the Soviet Union (1922–1991).  Rocket scientists and engineers contributed to the development of rocket and jet engine propulsion systems, which were first used for artillery and later for fighter aircraft, bombers, ballistic missiles, and space exploration.  Progress was greatly augmented by the reverse engineering of German technology captured by westward-moving troops during the final days of World War II and the immediate period following. Vladimir Andreyevich Artemyev (Russian: Владимир Андреевич Артемьев ) (July 6 [O.S. June 24] 1885 in Saint Petersburg - September 11, 1962 in Moscow) was a Soviet Russian rocket scientist at the Gas Dynamics Laboratory.  He was one of the inventors of the Katyusha.  The first rocket propelled by smokeless trotyl-pyroxylin powder was launched under his direction in 1928. Forced labor of Germans in the Soviet Union was considered by the Soviet Union to be part of German war reparations for the damage inflicted by Nazi Germany on the Soviet Union during World War II.  German civilians in Eastern Europe were deported to the USSR after World War II as forced laborers.  Ethnic Germans living in the USSR were deported during World War II and conscripted for forced labor.  German prisoners of war were also used as a source of forced labor during and after the war by the Soviet Union and the Western Allies.
Answer: Gas Dynamics Laboratory
