Bharat Karnad ji is known for spinning yarns about India-US-Russia relationship which has to be taken with a pinch of salt . We started negotiating with the Russians from 2004 for leasing two Akula-II class attack nuclear submarines and placed order for one of them in 2005 We also negotiated and...

I don't know but I don't think they are going to increase the fuel mass to empty mass ratio of the boost glide control vehicle . Gravity shaped is nothing but gravity turned trajectory where missile is turned in its early boost phase during the pitch maneuver guidance control in the open loop...

A look at the three trajectories MET , Lofted and Depressed with their CEP probabilities .

You have to balance the variables in testing in depressed trajectory the lift and drag force , re-entry heating , burnout parameters etc Once the vehicle has reached its pre determined apogee which will be lower than minimum energy trajectory the RV (Re entry vehicle ) trajectory now depends...

All our SLBMs will henceforth will not be fired with Minimum energy trajectory but only with depressed trajectory .Congratulations to all the people who are involved in the K-series program development. Now if only they could provide us a pic of K-4 .

Nobody knows but due to the lack of testing our warheads have low YTW ratio than Chinese making them only effective if they are launched in larger numbers . The reason for keeping reasonably high number of CANDU derivatives outside safeguard was precisely this to increase the amount of fissile...

No Arihant class may ever be converted to SSN/SSGN duty because of the under powered reactor and not enough second strike capability even with the larger boomers especially with our puny warheads period. If it is true then it is a good news . Well Russians might not help us as it will violate...

Don't know but upto 4 (guessing ) theoretically but the big problem will be the ejector system won't be able to eject the missile at great depth due to the small size of the system so the sub will have to come more near the surface making it vulnerable and the vibration of the launch will...

Actually it depends upon the Weight of the missile , Height of the missile (Able to fit in the hull basically around 13 to 14 mtrs), diameter under 2.5 meters and the capability of the cold launch/hard launch system to eject the missile from of the tube. You make a gas launch system able to...

Actually it depends upon how much is transferred to the turbines . Virginia's S9G reactor transfers 30 MW or 40 000 SHP but for Arihant it is lower more like 20 to 25 MW .

Seeing that Arihant is 6000 tonnes surfaced it would be possible that Arihant would probably have 8000 tonnes as submerged displacement. there is an mk-1 and mk-2 version of K-4 SLBM ?? Do you have any time periods for the future SSBN class after the three Arihant class because I don't think...

Arihant's weight is not known as information is sketchy but according to Bharat Karnad it is already 8000 tonnes submerged . Arihant can carry 4 K-4 SLBMs or 12 K-15 SLBMs. The S3 and S4 will be bigger than Arihant though how big we don't know though collectively they will be known as the...

It depends upon the diameter of of K-4/K-5 slbms they are trying to cap the height of the missiles at 13.1 meters given the pontoon testing of K-4 I think they may have achieved it . Agni-6 will have features which will have similarity with k-4/K-5 which means MIRV tech will be tested on Agni-6...

DT asymmetric SLBM K-4 and K-5 with MIRV will be our main stay of our SSBNs , India will probably put 250+ warheads in naval platforms in the future with 700+ in triad formation with fissile material for 2200 warheads in nuclear bunkers. We should try to make our submarine's SL spectrum...

Except probably KLT-40 (Sevmorput) how many Russian reactors have HEU as fuel . Most Russian reactors don't even have 100 GWdte burnups so Russian subs need to be refuelled every 10-12 years not like American subs which can operate upto 33 years at a stretch and need only one non reactor related...

How the hell did they even know about the exact power rating of our reactor , reactor geometry of Arihant the number of fuel pins and assemblies of our core etc obviously the SHP looks fishy for Arihant . Most naval reactors don't use HEU except probably US and Russian ice breakers so achieving...

It is between 80 to 86 MWth not MWe as real figures have not been revealed yet for this boat or anything like its SHP , cycle rate , burn up level , amount of fuel loading etc so every thing is in the area of pure guess work.

I think it will be wrong to unveil it especially with so many foreign navy present and any sophisticated submarine with passive sonar systems, such as towed array of hydrophones can ascertain the SL level of our SSBN , propeller cavitation signature ,engine and pump noise of ATV so it is not...

whatever little is available publicly Arihant reactor model 86 Mwt around 44000 SHP with modestly enriched fuel of around 40 to 45 % U 235
