The 1991 dissolution of the Soviet Union led to a severe decline in the Russian Navy. Defense expenditures were severely reduced. Many ships were scrapped or laid up as accommodation ships at naval bases, and the building program was essentially stopped. Sergey Gorshkov's buildup during the Soviet period had emphasised ships over support facilities, but Gorshkov had also retained ships in service beyond their effective lifetimes, so a reduction had been inevitable in any event. The situation was exacerbated by the impractical range of vessel types which the Soviet military-industrial complex, with the support of the leadership, had forced on the navy—taking modifications into account, the Soviet Navy in the mid-1980s had nearly 250 different classes of ship. The "Kiev-"class aircraft carrying cruisers and many other ships were prematurely retired, and the incomplete second "Admiral Kuznetsov-"class aircraft carrier "Varyag" was eventually sold to the People's Republic of China by Ukraine. Funds were only allocated for the completion of ships ordered prior to the collapse of the USSR, as well as for refits and repairs on fleet ships taken out of service since. However, the construction times for these ships tended to stretch out extensively: in 2003 it was reported that the "Akula"-class submarine "Nerpa" had been under construction for fifteen years.
