Submarine on fire.

On 7th April K-266 Orel (Eagle) caught fire during some repairs in Zvezdochka Shipyard in Severodvinsk. Insulation material in the ninth section of the sub has caught fire during welding works done by shipyard's workers.
Nuclear reactor was shut down, and the fuel was unloaded before the repairs started so there was no risk for radioactive contamination.

The sub was burning for 3 hours. There was no information about casualties on board of the sub.

K-266 Orel is an Oscar-class submarine the same type as Kursk which sunk in 2000 during exercise on Barents Sea. Both Kursk and Orel are type 949A which is designated Oscar II in NATO codenames.

Update.

British submarine dented.

British submarine HMS Talent suffered structural damage to the conning tower (sail) while surfacing under ice. At least officially. It's probable that the sub hit ice but you have to bear in mind that it was a popular excuse for sub damage during the Cold War. On May 23, 1981 HMS Scepter suffered damage after allegedly striking ice. It was later revealed that it collided with a Russian Delta III ballistic missile sub.

According to Daily Mail, ice ripped 6 ft hole in the sail. Submarine was able to reach port for repairs and will be out of service for several months.

The details of the incident are classified and we will not be able to know the details for a long time.

According to Royal Navy repair of the damage will cost 500 000£.

HMS Talent is a Trafalgar-class submarine. It was commissioned in 1990, as the sixth vessel of Trafalgar-class. This class of subs was designed as a hunter-killer. It has 5,300 tons of displacement and a length of 85.4 meters. Its power comes from one Rolls Royce PWR1 nuclear reactor. HMS Talent can reach up to 32 knots (59 km/h), submerged.

Russians intensity submarie patrols

Admiral Chirkov said on Submariner Day that Russian Navy intensify submarine patrols up by 50%. Good.  They keep their motherland secure as the admiral suggested.

In my opinion, however, the intensity of patrols went "over the roof"  because Russian Navy recently received a lot of new subs. Simply speaking they have vessels to use and perform detergent patrols and finally, since the collapse of Soviet Union, Russian submariners can do their jobs. Keep uo the good job.
