The N.G. Kuznetsov Naval Academy located in Saint Petersburg is the only academy of the Russian Navy. In 1827 Admiral Ivan Kruzenshtern initiated an Officers' Class at the Naval Cadet Corps. In 1862 the Class was reorganized into an Academic Course of Maritime Science. In 1877, to mark its fiftieth anniversary, the Class was renamed the Nikolaev Maritime Academy (Nikolayevskaya Morskaya Akademiya) and in 1910 was completely detached from the Naval Cadet Corps.
