The sinking by a torpedo hit of the Iranian frigate IRIS Dena on February 4 - some 375 km from the Indian shores - has ignited a fierce debate. The sinking of the warship returning to Iran after taking part in a multi-country naval fleet review in India cut too close for New Delhi’s comfort both in terms of its nautical proximity as well as its political fallout for Prime Minister Narendra Modi. Although the strike happened in the international waters, and reportedly after the US submarine commander warned the Iranian frigate, it has set off several questions. To understand some of the details MCR spoke to C. Uday Bhaskar, one of India’s foremost strategic and military affairs experts and a retired Indian Navy commodore.

00:16the sinking by a torpedo head of the Iranian frigate iris dina on February 4th some 375
00:27kilometers from the Indian shores has ignited a fierce debate in India. The sinking of the warship
00:33returning to Iran after taking part in a multi-country naval fleet review in India
00:38cut too close for New Delhi's comfort both in terms of its nautical proximity as well as its
00:45political fallout for Prime Minister Narendra Modi. Although the strike happened in the international
00:50waters and reportedly after the US submarine commander warned the Iranian frigate it has
00:57set off several questions. To understand some of the details MCR spoke to see Uday Bhaskar one of
01:04India's foremost strategic and military affairs experts and a retired Indian Navy Commodore Uday
01:13Bhaskar. Welcome to Mayank Shire reports Uday it's always a great pleasure to have you.
01:19Ditto Mayank you know I always look forward to being invited by you. Uday how common or normal is it
01:27for a
01:27nuclear submarine from any country let alone from the US to be essentially brushing past about 200
01:35nautical miles or 370 kilometers to the exclusive of the exclusive economic zone is that a common
01:42number one? Number one nuclear powered submarines are a very rare kind of underwater platform they're not too
01:53many of them only the major powers have them as in the United States Russia UK France China and India
02:02are
02:03the only nations that have this capability and when they are deployed they remain undetected
02:11generally and this is a thumb rule they do not come very close to the coastline of any other country
02:20unless there is an overwhelming operational need so in the specific instance that we are talking about
02:28which is the sinking of the Iranian ship the IRIS Dheena by the United States using an SSN which is
02:37the nuclear
02:38propelled submarine at a location which is approximately 30 nautical miles in Sri Lanka's exclusive economic zone so it's very
02:51approximate whether you say it was 20 nautical miles or 40 nautical miles it's a very small kind of difference
02:57you know in the
02:58maritime domain so that is unusual unless there is as I said an overwhelming tactical operational need and in this
03:08case it appears that the United States
03:10found it necessary or came to a determination that they would acquire this Iranian ship and neutralize it which is
03:16to say sink it by using a torpedo so this is an unusual occurrence both in terms of the proximity
03:25and the choice of the
03:28a spot in the ocean that is a spot in the ocean that is so close both to Sri Lanka
03:32and to India
03:35is it then are you saying clearly that nuclear submarines are not detectable period
03:42yes that's the thumb rule I mean that's why they are considered to be such potent platforms the idea of
03:48a nuclear powered submarine is that it remains underwater for extended periods it can be for months on end
03:55the endurance the endurance the endurance is determined not by the material state of the boat or the reactor but
04:00by the endurance of the crew
04:03otherwise
04:03I was thinking more in terms of when it approaches the surface as or it doesn't have to approach the
04:11surface
04:12nuclear powered submarine does not surface it only surfaces when it leaves harbor enters harbor
04:19I'm I'm the reason I'm asking these elementary questions is because these not these have not been explained by anyone
04:26so
04:26I'm glad you're clarifying that
04:28so that's the whole idea that when the first nuclear powered submarine the US is Nautilus had carried out a
04:35successful patrol
04:36it remains totally undetected and underwater so this is the USP of a nuclear powered boat that it can remain
04:44underwater for extended periods and the only sort of determining factor is human endurance or in the very unlikely event
04:54that there is some kind of a technical failure or a technical glitch that compares the submarine to surface
05:02okay
05:03okay
05:03so that's the difference between nuclear powered boat and
05:06and it could have fired the torpedo from any depth
05:10say again
05:11it could have fired its torpedo from any depths
05:14well technically the torpedo will be fired only when you have acquired the target
05:18fair enough but I'm thinking what depth should it be
05:21well basically it should be at you know a depth that would ensure that contact is made
05:27if you go too deep you know you have to traverse water which means that is three dimensional
05:33right
05:33you have to traverse a certain length you also have to surface to be able to hit the surface ship
05:39because the surface ship will only have a draft of between three to five meters you know depending on the
05:44size of the ship
05:45so therefore the submarine has to be launched at such a depth that it can both traverse the longitudinal you
05:52know the x axis and also the y axis to be able to reach that particular height
05:58so that's a very calibrated kind of a decision
06:00so in this case I'm sure the u.s submarine would have found an appropriate depth to make sure that
06:06the target was acquired and the torpedo made contact and the ship sank
06:09so it was successful but also historically I think the u.s secretary of war mr hexet made this point
06:15that it's after 40 1945 the end of world war 2 2026
06:23so we are talking of almost 81 years in terms of the use of a torpedo by a u.s
06:31summary because the last time there was such an exigency was in the four planes war of 1982
06:37and knowing your point is quite possible that you covered that war
06:41you are like Ripran Winkle
06:43now there is no war that we have not covered
06:47unfortunately unfortunately not
06:48but I'm glad
06:50Royal Navy UK used submarine at that time against Argentina
06:54but that which is why I said the use of SSN is a rare occurrence that's my point
07:00yeah
07:00now it's it's an interesting segue you gave me I was going to ask you about the fact that it's
07:05for the first time in Asia
07:0681 years that a torpedo was used how do you read is there any particular significance to that or just
07:12an operational detail
07:14no it's an operational detail meaning that if you have a capability you decide when to use it
07:19okay
07:20we just said earlier on that only six nations have nuclear propelled underwater platforms within that the United States leads
07:28the pack
07:29right
07:30the United States has only nuclear power submarines
07:33other countries have diesel submarines because they cannot afford to have only nuclear submarine nuclear powered
07:38and the SSN of the United States is in a class by itself
07:42it's a very lethal platform
07:44and any country uses military capability on an as required basis
07:48so in this particular case clearly
07:50President Trump and his team came to a determination
07:53that they would pick up an adversary an enemy ship in the Indian Ocean
07:57did they need to do it?
07:59my reading is perhaps not
08:01but then I'm not privy to the intelligence that the United States has maybe
08:04and this is my conjecture
08:06they could say that they had received intelligence that the Iranians are going to use the ship
08:10to pick up an American asset in the Arabian sea
08:14and therefore they have to neutralize it
08:16anyway this is actually not a point that we can really question because at war
08:22any enemy ship I'm talking about the naval maritime domain
08:26is a legitimate target
08:28right
08:29nobody I mean personally I would say that one cannot question as to
08:32was the US you know within its rights as it were in the conduct of war
08:38to carry out this torpedo attack
08:41the short answer is yes
08:44just one last technical detail before I get into a broader picture
08:49the Dina was a 1500 ton frigate
08:52typically how long does it take for a vessel like that to sink fully?
08:58oh that's an interesting question
09:00much depends on the extent of the damage
09:03suppose a boat is hit by multiple torpedoes
09:06you know there are cases where ships have been struck by more than one torpedo
09:10in which case the rate of sinking is much faster
09:14suppose you have three gaping holes
09:16at the right depth in terms of the ship taking in water
09:23then the rate of sinking would be much faster
09:26if the ship is struck only at one point
09:29where the crew is able to in a way
09:32make sure that it is watertight
09:34and only that part of the ship has water entering
09:37this has happened in World War II
09:38ships have been hit by torpedoes
09:41and they have managed to carry out damage control
09:44and in a way sanitize
09:45not sanitize but seal that compartment
09:47and ensure no more water would enter into the rest of the ship
09:49and they have actually used their propulsion
09:52to enter harbor and limp their way back to harbor
09:55it's an extraordinary phase of endurance
09:57so the warship is a very sturdy platform
10:00and of course if it is hit in a very very damaging way
10:03like in India
10:04if you remember we had the iris cookery
10:06in the 1971 war
10:08the Argentinians lost the cruiser
10:10in the 1982 Falklands war
10:12so much depends on where the ship is hit
10:15and the rate at which water enters
10:18and you know basically
10:20okay
10:21unstable and safe
10:22you know going by the unclassified video
10:25released by the U.S. Department of Defense
10:28one gets the sense that it's practically split into half
10:32and if you go purely visually
10:34yeah yeah
10:35you're right I mean that were the images that we saw
10:37that were released by the United States
10:40that it was yeah you're split
10:41it was literally I think you know
10:43hit your head center
10:45leading to this kind of destruction of the ship
10:48and it's falling
10:49which led to the thinking
10:50and just the final question about that part
10:53as a sailor of great standing yourself
10:57you were there in the Navy for 37 years I think
11:00right
11:00yes I was
11:02describe to me what goes through a sailor's mind
11:05I know it's difficult for you to speculate on that
11:09but something like that happening at sea
11:12what happens
11:13you know again I can only speculate conjecture
11:16in India because my you know own experience at sea has been limited
11:19I never took part in a war war
11:21for India the big naval war was 1971
11:26and we were under training at that time I had just joined the Navy
11:29but I do know by from talking to colleagues and those who were part of the 1971 war and who
11:36were on the cookery
11:38as a matter of fact I had course mates you know my contemporaries
11:41who were midshipmen sub-lieutenants at that time on board the cookery
11:46and their tales you know were something that we all shared as young people
11:49so that was a first-hand kind of account
11:51that it all happened in a split second
11:53you know meaning the ship is hit
11:55and there is obviously a lot of shall we say attempt to try and ensure that the damage is controlled
12:01which is why we use the term damage control on the ship
12:05but it's not successful
12:07and then in a matter of minutes you know you have lifeboats being lowered
12:11you have life rafts being cast
12:13and much depends whether it's dark or there is light
12:16has it happened in daytime or at night
12:18if it happens at night it becomes that much more difficult
12:20there is obviously a lot of chaos
12:23and there's a lot of shall we say you know
12:26destruction that has happened in the ship itself
12:28there could be fire
12:29there could be explosions depending on where the attack has taken place
12:33so it's a very very tragic kind of shall we say sequence of events
12:38now some of these of course have been brought into a visual frame
12:42particularly when you think of films like the titanic
12:45or if you think of any of the world war 2 films
12:47when you see both you know the expanse of the ocean
12:52and how puny the individual is the human being
12:56and then you are really at the mercy of nature and the ocean
13:02and when the end comes it's very swift
13:05unfortunately we cannot think of any first-hand accounts
13:08because once you have lost your life at sea
13:11only you know what are the thoughts
13:14the rest of it is we talk about people who were rescued
13:18and those accounts are with us
13:19but I think those final moments you know when you go down to the bottom of the sea
13:23and this is not something that's happened you know recently
13:28for centuries ever since the human species has endeavoured to cross the oceans
13:34ships have been sunk by natural disasters by storms or by human intervention which is to say that war-like
13:44activities have led to ships being sunk
13:47and many lives have been lost it's tragic
13:50it's also epic at one level you know when you think of how the human lives can be lost at
13:57sea
13:57yeah to broaden a bit do you think the US Navy should have or indeed did give its Indian counterpart
14:05any heads up on the presence of the submarine
14:08I'm not saying they are obliged to but do you think they should ask
14:13no again you know let me sort of try and attempt a nuanced response
14:16number one no submarine no Navy is going to give the adversary a headlong
14:22you are at war so the submarine commander would have been given instructions to pick up you know the target
14:28every Iranian ship is a legitimate target
14:31he the submarine would have definitely been given inputs
14:34there would be other agencies in the United States military tracking the ship
14:39so that information would have been made available
14:41and the entire US network that was engaged in this operation
14:47from the headquarters at different levels would be aware
14:50nobody would disclose the submarine's location or what kind of action it would take that is left to the commander
14:56but and this is the but that I want to introduce
14:59the United States could have perhaps done something more than what it did
15:04to ensure that there was a better rescue at sea
15:09more lives could have been saved
15:11that is my limited point
15:13no no I think you perhaps misheard
15:16I was not saying they should have alerted the Iranians
15:19I'm saying they should have perhaps given heads up to India
15:22given that we do not tired of talking about
15:25the 21st century's most important strategic relationship between the two countries
15:30you're right there's a lot of dismay in India
15:34about the fact that India was you know surprised
15:36the Iranian ship was a guest
15:38we had the international police review
15:40and the optics for the Modi government were not looking good at all
15:45and yes there's been a lot of dismay
15:47the opposition parties have also made very strong statements about this
15:51but objectively keeping the politics aside
15:54I would say that definitely for India
15:57this was a setback
15:59in terms of shall we say the optics of the whole event
16:03for the United States
16:05an operation of this nature
16:07would they have shared this information with India
16:10unlikely
16:11you know submarine operations are very confidential
16:14very secret
16:15only the submarine commander
16:17and his immediate vertical
16:18would know about the operation
16:20so I think it would be unfair to say
16:23that the United States should have informed India
16:25because then the onus on India becomes even more difficult
16:28you know suppose hypothetically
16:30the Indian government or the prime minister was informed
16:33what does he do
16:34can he inform Iran
16:36does he keep it with himself
16:37so I think this is not a
16:40understood
16:40probable situation
16:42yeah
16:43India was not in the loop
16:45indeed
16:46I have no smoking gun
16:48but I repeat this point
16:50that
16:51after the submarine had discharged its ordnance
16:54the torpedo and the ship were sinking
16:56the United States had the ability to ensure
16:59that the distress signals were picked up
17:02in a more enabling manner
17:04in this case if you remember the sequence of events
17:08it was the Iranian ship that put out the distress signal
17:11as they were sinking
17:13that was picked up by various agencies
17:15including Sri Lanka and India
17:16and because it was closer to Sri Lanka
17:19the Sri Lanka Navy was the first to respond
17:22and in turn they coordinated some activities
17:25but I personally am off the view
17:28I've said this in print when I wrote about this
17:31that
17:32perhaps the rescue effort
17:34could have been more nimble
17:37could have been more collective
17:39and could have been more empathetic
17:42and I believe that more lives would have been lost
17:44yeah
17:45and if you permit me since you are going to be showing this
17:47in the United States
17:48I have written an article in which I flipped the whole situation
17:51and spoke about a hypothetical scenario
17:54where if an American platform
17:59had been in a similar situation
18:01and it was American sailors who had to be saved
18:04because their ship had been struck
18:07and they were similarly
18:10shipwrights or survivors to be picked up
18:13and a distress signal had been sent
18:16my sense is that the regional response
18:20including that of India
18:21would perhaps have been far more nimble
18:25and more effective
18:26and more lives would have been saved
18:27so this is the slightly I would say to me uneasy
18:30and you know I am a bit
18:34saddened if I could put it that way
18:36that the code of the sea
18:38you know the code of the sea is that
18:40whenever there is a survivor who has to be picked up
18:42rescued
18:44it doesn't matter what national
18:45right
18:47the code of the sea says that whoever
18:49is able to should respond
18:50whether it's a merchant ship
18:52a warship
18:52it can even be a sailing boat
18:54I mean we have had instances in India
18:57of Indian sailors
18:58we have a very well known sailor in India
19:00Tomi Abhilash who won the Golden Globe
19:02who spoke about you know an occasion
19:04when he diverted his own sailboat
19:06because there was somebody who had to be picked up
19:09at sea because he was there and he heard
19:11he had got the signal
19:12so it's in that sense
19:14I'm of the view
19:15personal view
19:16minority view
19:18that the rescue effort
19:21could have been more empathetic
19:23and the United States is culpable in this
19:26okay
19:27to conclude
19:27we now know that India has indeed given refuge
19:31to another warship at Kochi
19:34which is at Kochi right now
19:35that's what I heard and read
19:37and that the Indian Navy did indeed respond to the Dina's distress call
19:42how do you read that in a broader strategic frame
19:45given that India has given severe criticism
19:49you know this is a very complex issue mainly because as you know apart from India
19:53Sri Lanka has also given access to another Iranian ship because it had a technical problem
20:00now what happens is that the United States and Iran are at war
20:05it's actually US plus one which is US and Israel you know versus Iran
20:09any nation that is seen to be providing support
20:14could be termed belligerent
20:16and given the kind of characteristics that we associate with President Donald Trump
20:21and the fact that he takes umbrage even you know shall we say
20:25when nations act in a certain manner it is seen as a personal kind of insult to him
20:30and he has used various measures to punish nations
20:33he has insulted leaders in public
20:36so nations are very wary
20:39and there is a protocol which says that if a man of war of a state that is at war
20:44has any kind of machinery failure or a humanitarian exigency
20:50and it has to enter harbour then there are certain guidelines under which a coastal state
20:56whether it's a Sri Lanka or an India in this case can provide that kind of access and support
21:01but this is a limited window
21:03but Sri Lanka has dealt with this I would say very intelligently
21:06which is that innovatively that they have allowed the Iranian ship to enter
21:11and they disembarked the entire crew
21:14the Iranian crew is technically now under quarantine
21:17not quarantine but definitely they are not on board
21:20so that way they are I am sure they are consulting and keeping the Americans informed
21:23but we have not had such a situation where the United States has been directly involved
21:28and smaller states whether it's Sri Lanka or countries like India
21:32have had to take a decision about how to deal with the humanitarian part
21:37because there is a convention a protocol to say that if a ship is in distress
21:41there is an obligation as per the conventions to provide that assistance
