During sea trials of aircraft carrier INS Vikramaditya upgraded in Russia for Indian Navy, serious failures were found in some systems produced in Poland and Great Britain, said Russian vice premier Dmitry Rogozin.
"Some defects were revealed in aggregates delivered by Poland and Britain. But aircraft flight tests passed successfully", Rogozin posted on his Facebook page.
Earlier on, president of United Shipbuilding Corporation (USC) Andrei Diachkov reported to Dmitry Rogozin on the situation around the ship. According to him, Chinese materials were used when assembling of boilers for the carrier. "The boilers were made on India's design. In Russian Navy, we use oil-fired boilers. But Indian partners wanted us to make boilers working on diesel fuel", reports Interfax citing Diachkov.
Answering Rogozin's question what materials were used for thermal insulation, Diachkov said that "fireclay bricks were made in China". "Unfortunately, Russia has lost production technology of that material", added the USC director.
As for him, boilers cannot work in full swing during dockside trials at the shipyard's mooring quay. "They were tested at 40% power", Diachkov said.
When the carrier reached full power for the first time at sea trials, fireproof brickwork in boiler furnaces was partially destructed, said the USC director.
