Project 11982 is a series of research vessels being built for the Russian Navy, developed by the Almaz Central Marine Design Bureau. The primary mission of this class is to conduct hydrographic and oceanographic surveys, as well as research activities in deep waters.

History

In November 2019, the Russian Ministry of Defence took the Pella Shipyard to court over delays to the project, with Ladoga being delivered to the Russian Navy two years behind schedule. The vessel Ilmen was scheduled to be handed over in 2018, however there has been no public information about its transfer to the navy.{{Cite web|url=https://newprospect.ru/news/articles/slishkom-usovershenstvovannoe-oruzhie-minoborony-i-pella-zaputalis-v-milliardakh/|title=Слишком усовершенствованное оружие.
