Question: The Tupolev ANT-37 design team operated under the guidance of a Soviet aerospace engineer who founded what?
Context: Mikhail Klavdievich Tikhonravov (July 29, 1900, Vladimir – March 3, 1974) was a Soviet aerospace engineer and scientist who was a pioneer of spacecraft design and rocketry. Nine years prior to the creation of the bureau, Pavel Sukhoi, a Soviet Russian aerospace engineer, took over team no. 4 of the CAHI's AGOS aviation, flying boat aviation and aircraft prototype engineering facility, in October 1930.  Under Sukhoi's leadership, the team of the future design bureau started to take shape.  The team, under the Tupolev OKB, produced experimental fighters such as the I-3, I-14, and the DIP, a record-breaking RD aircraft, the Tupolev ANT-25, flew by famous Soviet aviators, Valery Chkalov and Mikhail Gromov, and the long-range bombers such as the Tupolev TB-1 and the Tupolev TB-3. Tupolev (Russian: Ту́полев , ] ) is a Russian aerospace and defence company, headquartered in Basmanny District, Central Administrative Okrug, Moscow.  Known officially as Joint Stock Company Tupolev, it is the successor of the Tupolev OKB or Tupolev Design Bureau (OKB-156, design office prefix Tu) headed by the Soviet aerospace engineer A.N. Tupolev.  The company celebrated its 90th anniversary on October 22, 2012.  The Russian government merged Tupolev with Mikoyan, Ilyushin, Irkut, Sukhoi, and Yakovlev as a new company named the United Aircraft Corporation. Semyon Alekseyevich Lavochkin (Russian: Семён Алексе́евич Ла́вочкин ; September 11, 1900 - June 9, 1960), a Soviet aerospace engineer, Soviet aircraft designer who founded the Lavochkin aircraft design bureau.  Many of his fighter designs were produced in large numbers for Soviet forces during World War II. Mikhail Leontyevich Mil (Russian: Михаи́л Лео́нтьевич Миль ; 22 November 1909 – 31 January 1970) was a Soviet aerospace engineer.  He founded the Mil Moscow Helicopter Plant, which is responsible for many well-known Soviet helicopter models. The Mikulin AM-34 (M-34) was a Soviet mass-produced, liquid-cooled, aircraft engine.  Before the war, the Russian aero engine industry was mainly engaged in producing engines of foreign design, notably Wright, Bristol, Hispano-Suiza, and Gnome-Rhône.  Several engines of so-called original design have been developed, although these were probably largely based on foreign models.  The M-34 was thought to have been originally designed in Italy by Fiat for the Russians; its design closely follows Italian in-line aero engine practice.  Its initial development was troubled, but it eventually became one of the most successful Soviet aircraft engines of the 1930s.  It was utilized on the Beriev MBR-2, Tupolev TB-3, Tupolev TB-4, Tupolev ANT-20, Petlyakov Pe-8, Kalinin K-7, Polikarpov I-17, and Bolkhovitinov DB-A aircraft as well as the G-5 and various prototype motor torpedo boats.  A version of the maritime model was adapted for use in several prototype heavy tanks in 1939, although none were placed into production. V. M. Myasishchev Experimental Design Bureau (Экспери­мен­тальный Машин­ост­роительный Завод им.  В.  М.  Мясищева) or OKB-23, founded in 1951 by Vladimir Myasishchev) was one of the chief Soviet aerospace design bureaus until its dissolution in 1960.  Vladimir Myasishchev went on to head TsAGI.  In 1967, Myasishchev left TsAGI and recreated his bureau, which still exists to this day.  The bureau prefix was "M." s of 2003 , its workforce is estimated at approx­imately one thousand.  Myasishchev and NPO Molniya intend to use the V-MT or M-55 as launch vehicle for sub-orbital spaceflight. The Tupolev ANT-37 (or DB-2) was a Soviet twin-engined long-range bomber designed and built by the Tupolev design bureau, the design team operating under the guidance of Pavel Sukhoi.  The aircraft did not enter production, but three examples of the type were used for research and record breaking flights. Pavel Osipovich Sukhoi (Russian: Па́вел О́сипович Сухо́й ; Belarusian: Па́вел Во́сіпавіч Сухі́ ) (22 July 1895 – 15 September 1975) was a Soviet aerospace engineer.  He designed the Sukhoi military aircraft until the 1970s, and founded the Sukhoi Design Bureau. Boris Pavlovich Lisunov (Russian: Борис Павлович Лисунов , 19 August 1898 – 3 November 1946) was a Soviet aerospace engineer.
Answer: Sukhoi Design Bureau
