Russian help for the Indian Navy:

INS Vikramaditya has failed sea trials and its delivery to the Indian Navy may be again delayed by almost a year, Russian media reported citing defence and industry sources.

Seven out of the aircraft carrier’s eight steam boilers broke down when they were run at maximum power to enable the ship develop its top rated speed of 30 knots, an unnamed official of the state arms exporter Rosoboronexport told the Kommersant daily.

The official explained that the firebrick insulation of the boilers crumbled under impact of high temperatures...

The designer explained that the Indian side had objected to the use of asbestos in the insulation of the boilers because of feared health hazards and the manufacturer used other material which turned out to be sub-quality.
