Akademik Mstislav Keldysh is a Russian research vessel operated by the Russian Academy of Sciences. Named after Soviet mathematician and academician Mstislav Keldysh, the ship is primarily employed for oceanographic, geological, and polar scientific missions, as well as for the deployment and support of deep‑submergence vehicles.

Capabilities
The vessel is equipped with a variety of scientific laboratories (hydrography, marine biology, geology, physical oceanography), winches, and a moon pool for handling submersibles. It features dynamic positioning and a helipad for medium‑size helicopters. The ship’s deck can accommodate and support deep‑sea submersibles such as the MIR and TURMER series, as well as remotely operated vehicles (ROVs).
Operational history
| Year | Mission / Note |
|---|---|
| 1989 | First major expedition: supported the MIR submersibles in the historic dive to the wreck of RMS Titanic. |
| 1991‑1995 | Conducted extensive magnetic and seismic surveys in the Barents and Kara Seas, contributing to Arctic resource assessments. |
| 1996 | Participated in International Ocean Discovery Program (IODP) drilling operations in the North Atlantic. |
| 2005‑2007 | Returned to the Titanic site for follow‑up surveys and high‑resolution imaging with MIR‑2. |
| 2008 | Served as the launch platform for the Russian “MIR‑2” submersible’s record‑depth dive to 10 700 m in the Mariana Trench (support role). |
| 2012‑2014 | Conducted multi‑year research cruises in the Arctic Ocean, focusing on climate‑related sea‑ice dynamics and carbon cycling. |
| 2016 | Assisted in the recovery of a Russian military aircraft wreckage in the Barents Sea. |
| 2020‑2022 | Underwent a mid‑life refit at the Sevmash yard, which upgraded navigation, communication, and scientific equipment, and replaced aging diesel generators with more efficient units. |
| 2023 | Supported a joint Russian–Chinese scientific expedition in the Pacific Ocean, deploying a suite of autonomous underwater vehicles (AUVs) for biodiversity mapping. |
Notable contributions
- The ship’s deep‑sea capabilities have made it a central platform for Russia’s MIR submersible program, enabling a series of record‑depth dives and the exploration of several historic shipwrecks.
- Data collected during Arctic cruises have been incorporated into global climate models, particularly concerning sea‑ice thickness and ocean heat transport.
- The vessel’s seismic and magnetic survey work contributed to hydrocarbon prospecting in the Russian Arctic shelf areas.
Ownership and management
Akademik Mstislav Keldysh is owned by the Russian Ministry of Science and Higher Education and operated under the auspices of the Russian Academy of Sciences’ Institute of Oceanology. The ship’s operational schedule is coordinated with national and international research programs, and it frequently hosts scientists from partner institutions worldwide.
Current status
As of 2024, Akademik Mstislav Keldysh remains an active component of Russia’s research fleet, regularly undertaking multidisciplinary scientific voyages in the Arctic, Atlantic, and Pacific Oceans. The vessel continues to serve as a primary launch platform for deep‑submergence vehicles and advanced oceanographic instrumentation.
