And how many patrols does the Indian Navy manage a year, according to US naval intelligence's definition of a patrol? Zero?
No patrol doesn't mean staying at base.
Chinese Submarine Patrols Doubled in 2008 » FAS Strategic Security Blog
Note that it mentions that China conducted more patrols than Russian in the same period.
Assuming that deterrent patrols entail voyages with nukes, neither of India or China conducts or will likely conduct them. Both countries keep warheads and missiles stored separately.
The few Russian Kilo's China imported are of poor quality, as are the imported Sovermeny's. One of the Kilo's' battery blew up a few years back. The Russians blamed it on the Chinese crew. Later, the same thing happened with an Iranian Kilo operated by a Russian crew. Several Chinese Kilo's have been in dry dock for extended periods of time and they rarely go on patrols. And of all the modern surface vessels in the Chinese Navy, only the Sovermeny's haven't bee on anti-piracy missions.
@ No one in particular and in response to ice berg's post
Most members on this board do have big mouths. World class military industrial complex comes from hard work, investment and time. No one is inherently more innovative or adept at quality control. Even if some one is, its usefulness is over-shadowed by effects of organisational structures, institutional framework, funding and accumulation of know-how over time. If they think slogans like 'Chini propadanda' can nullify years of trying, they've got another thing coming.
While most nationalistic Chinese and Pakistani fan boys think that Arjun II will be a failure like its predecessor, I'm of the contrary opinion, because the Indians will learn from any mistakes they've made in Arjun. Same thing with the Chinese, except that the Chinese has had way more experience, made way more mistakes and learned way more than you.
