The Doom of the Kursk and Its Crew Was on Putin’s Hands

 

The Russian nuclear powered attack submarine Kurst designed during the last days of the USSR was one of the most modern and prestigious ships in the new Russian Navy.  She was better maintained than most of the fleet but even she was not in top condition as noted by visible rust on her hull and her crew lacked training. 

Note—This is a reminder of how long Vladimir Putin has held sway over Russia one way or the other.  The Kursk affair exposed how hollow the Russian armed forces really were after the collapse of the old Soviet Union.  Now the War on Ukraine has chewed up and spit out his Army exposing beyond a few elite units troops were ill trained, poorly armed and equipped, and often actually hungry.  Vaunted Russian heavy armor and artillery was shown to be poorly maintained and apt to breakdown.  They were vulnerable to small arms attacks and shoulder fired rockets.  Their massive weight confined them to roads where ambush was easy and one dead tank could clog the road leaving columns vulnerable. 

On August 12, 2000 the Russian submarine K-141 Kursk sank in shallow waters in the Barents Sea (north of Russia and northeast of the Scandinavian Peninsula) after being ripped apart by two powerful explosions.  All 118 officers and seamen aboard died, although as many as 23 may have lived for days in an aft compartment fruitlessly awaiting the rescue which at the shallow depth of 354 feet should have been possible. 

The Kursk was the largest nuclear powered attack submarine ever built.  It measured over 500 feet long and was four stories high at the conning tower.  Designated by NATO as an Oscar II Class sub, it was designed in the waning days of the Soviet Union but was the first ship completed under the Russian Republic in 1994. 

It was a very technologically advanced warship.  It’s thick, extra-hard high nickel chrome content stainless steel was corrosion resistant and left a weak magnetic signature deterring detection by NATO Magnetic Anomaly Detection (MAD) systems. There was a nearly 7 inch air gap between the outer shell and a thick steel inner hull.  The ship could carry 24 anti-ship cruise missiles armed with either conventional high explosives or tactical nuclear war heads and several torpedoes. 

The Kursk was assigned to the Russian Northern Fleet and based at Vidyaevo in the Kolsky District of Murmansk Oblast.  In the turmoil following the collapse of the Soviet Union and the resulting economic crisis and hyper-inflation, the condition of the Northern Fleet deteriorated rapidly.  Much of the fleet was allowed to rust at anchor.  Maintenance of even active ships was neglected, including care for the Russian Navy’s specialized submarine rescue ships.  Sailors went without out pay for as long as two years and were sometimes seen in villages in the area literally begging for food.  Many experienced officers and men left or abandoned the service.  Training was neglected.  The Kursk, considered a show piece and object of national pride, fared better than most of the fleet, but certainly was not up to top operational standards. 

When tough guy Vladimir Putin assumed control of Russia in 1999, he made rebuilding the military and Navy a high priority.  The Kusk was one of the ships that benefited from his attention.  Freshly outfitted, Putin dispatched it on a mission in the Mediterranean to monitor the U.S. Navy Sixth Fleet during the Kosovo War. 

After that successful flexing of naval power, the Kusk was assigned that August to the Northern Fleet’s largest training exercise in nine years.  The exercise involved four advanced attack submarines, the fleet's flagship Pyotr Velikiy (Peter the Great) and a flotilla of smaller ships.  The Kusk was making attack runs at the Pyotr Velikiy using dummy torpedoes when an explosion wracked the bow of the ship at 11:28 AM local time followed by an even more powerful blast, which was recorded at the equivalent of 3 to 7 tons of TNT, a little more than two minutes later. 

The second explosion sent debris through most of the length of the submarine.  The ship sank quickly with the immediate loss of most hands.  However, the Captain, Lieutenant Dmitriy Kolesnikov, and twenty-two others made it to a sealed compartment in the aft where they survived for some time.  

 

 Kursk was salvaged by Dutch companies which cut away the bow where possible nuclear-tipped cruise missiles may have been located.

Russian authorities have always maintained that they must have died quickly, but evidence from salvage operations conducted in 2001by the Dutch companies Mammoet and Smit International indicated that they may have awaited rescue for days before being killed in a flash fire in the half-submerged compartment. 

Soon after the accident British and Norwegian ships monitoring the exercise offered to come to the rescue of possible survivors.  But Putin, who was on vacation on the Black Sea, and Navy brass turned down the offer out of a combination of national pride and to protect secrets about the ship’s capacity and armaments.  Russian attempts at rescue and recovery were unsuccessful.  Putin did not return to Moscow or issue a public statement on the disaster for a week. 

The best reconstruction of the accident indicated that a hydrogen peroxide fueled supercavitating torpedo exploded when the highly concentrated propellant seeped through rust in the torpedo casing and exploded.  Heat from the first blast set off six or seven torpedo war heads and the secondary explosions were probably fatal to the ship.  

 

Vladimir Putin was interviewed in 2000 about the Kursk catastrophe on RTR, the international service of VGTRK, a state-owned Russian broadcaster.  He denied there were nuclear weapons aboard and tried to deflect blame.

These kind of hot torpedo accidents were a known hazard to submarines.  A similar accident sank the British sub HMS Sidon in 1956 and is the principle suspected cause in the loss of the U.S. Navy’s USS Scorpion in 1968. 

Russia always denied that the ship’s missiles were armed with nuclear weapons, but it was a concern for the salvage companies, who cut the ship’s bow away from the rest of the boat before raising her.  The bow, including much of her armament, was destroyed by explosive charges in 2002.  The reactor was defueled and taken to Sayda Bay on the northern Kola Peninsula where reactor compartments were floated on piers.  The rest of the hulk was cut up for scrap.

 

 The conning tower of Kursk today serves as a memorial in Murmansk.

The loss of the pride of the Northern Fleet, the botched attempts at rescue, and the fact that salvage had to be performed by Western companies despite a shallow depth close to Russian shores remains an embarrassment for Russia and for Vladimir Putin.

The USS Nautilus Was First Under the Ice and Across the Pole

 

The USS Nautilus under the Polar ice cap. 

On August 3, 1958 the USS Nautilus, the U.S. Navys first nuclear powered submarine, crossed the North Pole under the Polar icecap.  Under the command of Captain William R. Anderson, 111 officers and crew plus four civilian scientists were on board when the ship submerged off of Point Barrow, Alaska and sailed without surfacing over 1,000 miles before passing under the Pole.  She then continued submerged until she finally surfaced between Greenland and Spitzbergen on August 5. 

Within days the achievement was touted to the press as a scientific breakthrough as part of the widely hyped International Geophysical Year.  President Dwight D. Eisenhower awarded Anderson the Legion of Merit.  

 

The1968 action thriller Ice Station Zebra starring Rock Hudson and Ernest Borgnine, a U.S. nuclear submarine is sent on a mission to save the crew of a weather station on the ice near the North Pole but are confronted by Soviet paratroopers in a stand-off that could lead to nuclear war.  The film was based on the dangerous game played by both nations at the top of the world  

But there was more—much more—than science afoot in the Arctic.  The real reason for the mission was the strategic game of cat and mouse being played between the U.S. and the Soviet Union over control of Arctic waters.  Submarines of both nations prowled the water there for decades during the Cold War often resulting in dangerous, but highly classified, confrontations.  The films Bedford Incident and Ice Station Zebra were based on this perilous game. 

The USS Nautilus was built in Groton, Connecticut by General Dynamics Electric Boat Division under the personal supervision of Admiral Hyman G. Rickover, the Father of the Nuclear Navy. Her power plant was the S2W naval reactor, a pressurized water reactor by Westinghouse Electric Corporation and is the basis for the design of nuclear propulsion still used by navies around the world.  

 

 Mamie Eisenhower did the honors at the launch of the Nautilus in 1954.

She was christened by Mamie Eisenhower on January 21, 1954, ran under nuclear power on the morning of January 17, 1955, and was commissioned on September 30, 1954, under the command of Commander Eugene P. Wilkinson.  She almost immediately began to smash records for endurance—total time submerged, and distance traveled.  In the mid-‘50s she was the most publicized ship in the Navy, her very existence a cautionary shot over the bow of Soviet naval ambitions. 

She was named for the famous submarine build and sailed by mad Captain Nemo in Jules Vernes pioneering science fiction novel Twenty Thousand Years Under the Sea first published in France in 1870.  As you may recall Nemo wanted to build a super weapon that would enforce world peace by making war too terrible to contemplate—just the supposed mission of American nuclear arms.

The ship remained in service until decommissioned in 1980.  Since 1986 the USS Nautilus has been on display at the Submarine Force Museum in Groton.

Today the vast polar ice cap under which the Nautilus sailed has greatly shrunk under conditions of relentless climate change.  For summer months there is now open water completely around the sea ice, which is also thinning and apt to break up.  Polar bears, walrus, and fur seals are all endangered as are the livelihoods of indigenous peoples in the Arctic from Siberia, Alaska, Canada, and Greenland.

Nuclear submarines from the U.S., Russia, and the United Kingdom have all surfaced through less than three feet of ice near the Pole.
