However The news is not correct regarding the Retirement plan of Indian Navy
The news states that India currently has 14 Subs ie 10 Kilo Class and 4 Type 209 Subs , out of which India would be left with 7 Subs by 2015
That Figure is absolutely bogus , it is based on the assumption that indian navy will retire its subs after 25 yrs in service
However as per Navy chief first of Kilo class will Retire in 2015 after 29 yrs in service while the first Type 209 will retire in 2017
Also news says that Indian fleet will decline to 7 by 2015 , which is also not correct as it doesnot take into account 3 Arihant class and 1-2 Akula II Class Subs which india will induct in next 5 yrs
By the way India is also upgrading 7 Kilo class and 2 Type 209 Subs , out of which 7 Subs ( 5 KILO , 2 Type 209)have been upgraded , after these upgrades these 9 subs could serve if required till they are 35 yr old
Let us just assume that India does retire a few subs before 2015 , i still dont think that combine number would fall below present 14 ie it could be 10 diesel electric + 4 Nuclear Powered , frankly i dont see India retiring the upgraded subs before 2018
