Project 1710 Makrel (Russian: 1710 «Макрель»; NATO reporting name "Beluga") was a Russian SSA diesel-electric submarine.

It was an experimental vessel used for testing propulsion systems, hull forms, and boundary-layer control techniques.

Development was undertaken by the Malakhit Design Bureau with construction at the Admiralty shipyard in St. Petersburg.

Launched in 1986 and moth-balled around 1998, the last operation of the vessel is thought to have taken place in 1997.
