Navrotsky said the Northern Fleet and Zvezdochka shipyard signed the document about dismantling in the beginning of the year, but after K-159 accident the Russian Defence Ministry banned tugging of the retired submarines to the shipyards for dismantling. The ban concerns all the retired submarines regardless of the earlier agreements. The decision to relocate these two submarines to Zvezdochka would be made by the Ministry of Atomic Energy, Ministry of Economic Development, the Defence Ministry and only after approval of the technical project on tugging and not before 2004, Navrotsky added.
