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." As of 2003[update], 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.
