List of lost Russian or Soviet submarines

These Russian or Soviet submarines either suffered extensive crew casualties or were entirely lost to enemy action or to "storm or perils of the sea." A dagger (†) indicates that the boat was lost.

According to the U.S. Navy, "The former Soviet Union secretly disposed of about 16 submarines by sinking them in the northern oceans."
