Pakistan Successfully Tested Babur 3 Cruise Missile launch from Submarine : ISPR

[Safriz]

@ShoutB

"Launching missiles from torpedo tube and calling it secpnd strike is so shameful."
Then the Israeli navy is also shamefull. And to the extent that USN and Russian Navy rely heavily on tube launched cruisemissiles (many of which are or can be nuclear armed), this is also a silly remark.

"For 1 second even if i believe that its launched from sub. Then its diving up submarine , nose up, and launching this missile from torpedo tube."

See my posts on (or look up) "encapsulated missile launch". The submarine doesn't 'nose up' for launching missile from torped tube.

The ISPR video has no tug boats in sight, which would be there if pontoon was used for the launch as pontoons need tugs to move and remain in place.
That itself is evidence that it was a submarine launch not a Pontoon launch

Independent underwater propulsion

Would mean additional security for boat and crew.

Short summary of capable countries.

The ISPR press release also mentioned "Independent underwater propulsion " system with Babur SLCM.
Any comments on that?

Sm-39 Exocet:
"Housed in a water-tight, highly resistant, propelled and guided underwater vehicle, the aerial missile is ejected as soon as it breaks the surface, to ensure a very low culmination altitude. It then rapidly homes into the target at sea skimming level: it uses an inertial navigation system followed by autonomous terminal guidance from an active RF seeker."

This can be used for other (kinds of) missiles too e.g. Mica anti-air missile.

Similarly Harpoon UGM version: encapsulated

You see there is a difference between Exocet and Harpoon as to when the missile leaves its capsule.

Whole world seems to b educating an illeterate randian.... and he does not want to learn...i m suspecting he is the expert from times now video

Good observation by the way about tug boat

You could anchor a pontoon.... or have it kept in position dynamically.

@Zaki @DESERT FIGHTER @The Eagle @Kaptaan @Basel @war&peace @Khafee @Rashid Mahmood @django @Zibago @Zarvan @AUz @Windjammer ... The world is Laughing at Pakistan for this Test ,and we are exposed once again .. for all those who can understand Hindi/Urdu Enjoy this peace of Comedy ... and one thing the Anchor say that i agree with , by the time this Video End , you all will be Laughing ..

Simply WOW..... These are same experts that lastly showed JF-17 on their defence day poster with an underbelly Indian flag as an Indian A/C so what to expect. Also, the same experts are not even aware of such horizontal/ encapsulated launch. The difference of colour is due to light effect and camera quality as well. Experts who actually calculate the speed through a shortened video which is shared merely for reference and doesn't contain much detail. However, the paid experts are actually propagating to have a bit of details to read the tech. They couldn't believe in another video, a CM could actually be filmed and video can be recorded and for all above, the standard of comparison is because India couldn't do.

However, the message is sent and professional knows what happened. Babur-III is actually proven as top psyop weapon in test that strikes many minds.

The Federation of Atomic Scientists’ explain the procedure used in the sub-launched Harpoons as follows:

“The submarine Harpoon is contained within a capsule and is called ENCAP for encapsulated. The ENCAP is the same size and general shape of a blunt nosed torpedo and is launched from submarine torpedo tubes. It has positive buoyancy (it floats), so when it is ejected from the submarine, it will rise to the surface, without power. The ENCAP consists of a nosecap, main body and afterbody. The missile is on shock isolator rails within the main body. The afterbody has fins which direct the ENCAP towards the surface at the proper angle for missile launch. Once the ENCAP breaches the surface, the nosecap is blown off by a small rocket and the missile is launched.”

Kongsberg encapsulated NSM

INcidentally, Northrop has yet another launch method.

So basically they meant the canister for babur. Thanks

Possible. But a more expensive option .
Anyway the canister can be seen here.

Hence the difference between Exocet and Harpoon capsules: that of Exocet is propelled and leaves the water befoare Exocet is started, that of Harpoon isn't and that missile launched as the capsule is are the surface.

Yes. Greater subs have vertical launch tubes. Pakistan subs have vertical tubes.

Exocet is propelled

is it gas pressure propelled ?

yeah , but the Video must have given you a good laugh bro , and you might now feel more sorry for these Indians haha

Yes?

I have no idea.

Found a technical explanation :

Actually, the submerged portion of the launch is on a column of compressed air, which gives enough boost to cut through about 150 feet of water before breaching the surface, where the rocket motors ignite.

The air is compressed by a small, contained explosion, something like the explosion in the cylinder of a gasoline powered automobile, but in this cases uses a column of super heated steam.

The inside of the missile tube is dry. After the outer hatch lifts away, a seal at the top of the tube is blasted away by a small charge. In a split second, before water can flood the tube, the shot of compressed air boosts the missile away from the sub. The momentum is sufficient to push the missile to the surface. Inside the missile, when sensors detect deceleration, the rocket motors ignite.
That gets us out of the water - but what happens next?

If you watch enough missile launches, you'll notice that many times the missile appears to be doing a bit of a dance before it finally flies true. That's owed to the uncertainty of launch conditions; sea currents, wind, variances in the column of compressed air, etc. In the equipment section of the missile, inertial controls detect the hull's deviation from course, and send correcting pulses to the TVC (thrust vector control) which steers the missile by changing the angle of thrust exhaust from the gimbaled motors.

Once on steady flight, an onboard camera starts looking for a certain star to use as a point of reference for celestial navigation -same principle as mariners used centuries ago. Once locked onto the star, corrections are made as required to keep the missile on course. Perhaps curiously, while GPS systems are carried on some vehicles, they are not part of the guidance package, for the simple reason that the GPS system, itself, might be compromised or out of service in the event of hostilities. Their purpose, where used, is to verify accuracy and refine accuracy of the other guidance instruments.

I have never seen indians so disoriented and dumb as i have seen them after launch of Babur 3. Is this the nation which claims to be a super power by 2030? You loosers cant even swallow achievements of Pakistan yet you try compete with like of China and US.

BC even we launch Babur 3 up your arse hole you will still try to prove it fake.
