What???Well, even if/when it is leased to India, formally it would still be in the VMF (Russian Navy). My understanding is that the Indians would conduct realistic training on it (or another SSN) under Russian sailors' supervision.
Russian expert hints gas mask shortage raised submarine toll: reportOlder generation non-water based fire suppression systems are pretty fearsome once activated, they typically destroy the oxygen content in the air in a matter of seconds. Ordinarily an alarm will sound prior to activation giving the crew time to don breathing apparatus or get the hell out of there. Sounds like the Russian's are using an older system, which has largely been replaced in the West by an non-water based solution, which does not rely on the removal of the surrounding airs oxygen content.
exactly. none of us should lose sight of the fact that people lost their lives. the technology issues need to bear that in mind.I hope a genuine and sincere effort is made towards identifying the cause of this accident so that such tragedies do not occur in future.
