MOSCOW, January 25. /TASS/. The Project 11711 amphibious assault lead ship Ivan Gren will be delivered to the Russian Navy no sooner than November, President of Russia’s United Ship-Building Corporation Alexei Rakhmanov said on Wednesday.

"Perhaps, this will happen no sooner than November because quite a complex problem has surfaced with the degaussing system, on which work is currently under way, and we’ll be able to finish this work," Rakhmanov said.

The most important thing now is that scientists should confirm the accuracy of calculations so that "we do not have to slash it again" subsequently, he said.

"Unfortunately, the Ivan Gren has had such a hard fate: the ship has been under construction for almost 14 years, and not even an enterprise within the United Ship-Building Corporation began to build it, and over this time the technical requirements for the vessel have changed three times," Rakhmanov said.

The Project 11711 large amphibious assault lead ship Ivan Gren was laid down at the Yantar Shipyard in Kaliningrad in December 2004 and put afloat in May 2012.
