Captured by Russian forces on 22 March 2014 (during the annexation of Crimea), half of the Ukrainian personnel, among them the captain of the submarine, had left while the others chose to begin their service in the Russian Black Sea Fleet with the submarine.

[2] In 1970 she was commissioned into the Soviet Red Banner Northern Fleet,[2] where she conducted 14 patrols, including a port call in Cuba.

But it was only in 2003 when Ukrainian government was able to buy a new set of batteries and make Zaporizhzhia's survival real.

Being on a years-long repair, Zaporizhzhia was an inactive military unit stated Defense Minister Anatoly Hrytsenko in April 2006.

[3] In January 2007, (Defense Minister) Hrytsenko stated that Ukraine intended to sell Zaporizhzhia.

[citation needed] Zaporizhzhia was placed under Black Sea Fleet control, after Ukrainian symbols were removed from the submarine.

On 29 March 2014, the Black Sea Fleet was reported to have refused to add the submarine to its ranks on the grounds that it was obsolete and suffered from a number of technical issues.

The Russian Navy then offered to return Zaporizhzhia to Ukraine to either continue its service or to be recycled as scrap-metal.

[18] As of 29 December 2020, Google Maps imagery showed U-01 afloat and pier-side in Yuzhnaya Bay in Sevastopol surrounded by containment booms, next to Romeo-class submarine S-49.

[19] From September to November 1970, submarine was at sea for 20 days, 422 hours (236 submerged, 186 surfaced).

During the service in the Atlantic Ocean in June through December 1971, the submarine was at sea for 210 days.
