<P> The Arihant - class submarines are nuclear powered ballistic missile submarines built under the Advanced Technology Vessel ( ATV ) project . They will be the first nuclear submarines designed and built by India . The submarines are 112 m ( 367 ft ) long with a beam of 11 m ( 36 ft ) , a draught of 10 m ( 33 ft ) , displacement of 6,000 tonnes ( 5,900 long tons ; 6,600 short tons ) and a diving depth of 300 m ( 980 ft ) . The complement is about 95 , including officers and sailors . The boats are powered by a single seven blade propeller powered by an 83 MW ( 111,000 hp ) pressurised water reactor and can achieve a maximum speed of 12 -- 15 knots ( 22 -- 28 km / h ) when surfaced and 24 knots ( 44 km / h ) when submerged . </P>
