Sergei Kovalyov, the designer of three generations of Russian strategic submarines said that due to lack of funding, the developers had been unable to conduct test launches from a floating pad to test the underwater segment of the missile's trajectory. He also said that there were insufficient funds to conduct ground-based test launches. Both types of testing had been standard procedure during Soviet times. Kovalyov also criticised the poor quality of missile components provided by a large number of sub-contractors and the absence of military representatives at manufacturing plants.
