My point was regarding it's ejection mechanismand not about it being intermediate or Intercontinental.How many intermediate class missiles are featured in SSBN worldwide ? most are near or over 2m dia class.
read my post again I said about necessary depth.... What other purpose do u think that nose fearing is for if not for providing necessary push to missile from sea.No submarine ever fires its missile from deep down. The max depth for such missile launches is just abt 80m.
