Russia admitted on Thursday that a secret plan of a new long-range nuclear torpedo was revealed on state-controlled television stations.
During ordinary news bulletins from NTV and Channel One, a military official was shown looking at a confidential document containing a plan of the "Status-6" torpedo designed by the St. Petersburg based company Rubin.
"It's true that some secret information was caught by the camera and therefore it was subsequently removed," Kremllin spokesman Dmitry Peskov said after the footage appeared on TV.
"We hope this will not happen again," Peskov added.
According to the document, the system has nuclear submarines carrying massive long-range underwater drones which could create "extensive zones of radioactive contamination."
The document also said that the Status-6 system is designed to "destroy important economic installations of the enemy in coastal areas and cause guaranteed devastating damage to the country's territory by creating wide areas of radioactive contamination, rendering them unusable for military, economic or other activity for a long time."
The footage of the plan was captured during a meeting between President Vladimir Putin and military officials in Sochi on Monday.
The two state controlled TV channels removed the footage, however, some websites have continued to host it.
However, the taking down of the videos did not end the questions over the leak of the plans. It remains unclear how the images could be shown by accident on the tightly state controlled channels.
Some Russian and US weapons-watchers have claimed that the TV leaks may have not been accidental, but rather might have been a way to send a message to the US, whose officials believe that Kremin is developing a nuclear “drone.”
Following the incident, the leading state-run paper, Rossiskaya Gazeta, reported details regarding the weapon, without showing the diagram that appeared on TV.
Since the conflict in Ukraine began last year Putin and other Russian officials have made frequent references to the country’s nuclear arsenal.
Putin announced in June that Russia would deploy 40 more missiles, claiming that there is no choice for the country aside from boosting the capablity of nuclear weapons to defeat US missile-shields.
