Hangor Class Submarine | Updates & Discussion

[Ak01]

Yeah but they still need something till it bears fruit.

not 1 billy worth of something!

 

[Pakistan First]

Anything about the torps? BTW it took basically exactly 2 years from launch to commissioning for the hangor based on this we could see at least 2 Chinese hangors being delivered next year and 1 more either later that same year or early 2028, we might see the first Pakistani hangor launched too next year hopefully.

Yup I think All 4 chinese ones will be commissioned by the end of 2027. Baki Pakistani wali Allah jany. Don't expect any of them to be commissioned before 2030.

I think the first being built in KSEW could be launched by end of this year. Here's few months old satellite photo:

its not that bad

5th units and 1st from Karachi was steel cut 9th Dec 2021 and keel laid in 24th Dec 2022
6th units and 2nd from Karachi was steel cut 24th Dec 2022 and keel laid 14th feb 2024

when they cut the steel plates they then build the block or module and when the module is completed they lift it down into the construction hall which is what they call laying the keel

so 5th unit is 54 months on and 6th unit is 41 months on

Because Pakistan previously built the later boats of the French-designed Agosta 90B-class submarine programme at Karachi, the shipyard already had submarine construction experience before the Hangor project started

so 5th is expected to be launched in Q1-Q2 2027
and 6th is expected to be launched in Q1-Q2 2028

and since the program is not single 1 staggered test and evaluation but rather a simultaneous synchronised program the 7th should get steel cut after 5th is launched and so on

the 2nd, 3rd and 4th units from China will be delivered by end of 2027

with 5th from Karachi in the water plus the 1st one that is commissioned thats 5 units

so we will have 5 x Hangor Class in the water within 12-18 months, this program is moving very fast

This is not a Hangor but a Agosta, look at the fins near the nose

 

[Princeps]

And none on the sail, so this is a Agosta 90B.

no no, thats submerged, snorkel range is 8500nmi!

MESMA will almost always give higher speeds and endurance because it priorotises higher power ceilings.

In its workings MESMA is literally a nuclear reactor, where the nukey bits are replaced with ethanol and liquid oxygen for heat. In theory, PN could actually reverse parts of MESMA into a functioning nuclear propulsion system, if they were able to develop an approriate SMR. MESMA is probably louder (we talk in relative terms because all of these are designed with accoustic stealth in mind anyway) vs stirling, it has alot of pumps, turbines, and moving parts, whereas stirling cycles are relatively simpler. But being lower power, you wont have the kinds of endurances or impressive speeds of MESMA. One of the biggest benefits of a nuke boat is its big underwater speeds, maybe like 5-10x that of stirling cycle aip, whereas MESMA equipped A90B will submerge at 2x the speed of a Yuan if needed. Basically, MESMA is a massive key in NRDI/PAEC possibly being able to develop the downstream for a nuclear propulsion system for boats.

Unless I am jumbling up my memory - they did look into it further but the additional study, SMEs and other resources required were not present.

The approach for the currently mothballed SSN concept was looking at an older gen "allied" reactor for which they had identified willing partners(read folks from Eastern Europe and other places who dont mind spending their winters in Pakistan for a hefty compensation) to "modernize" the otherwise mid 60s design.

But as usual...

PN has an original HWT torpedo program, guess this has something to do with it.

And more impressive off board shooter programs that tie into providing coverage where a Hangor or A90b hears something, pushes to something in the air and that air pushes to something else which loiters around various areas -- and which is the shooter.

What the IN is trying to accomplish with the MQ-9s, their land launched long range AsRoc - the PN has nearly duplicated at 1/10th of the cost.

Turkiye might be keeping an eye for re: funding. They also want an SSN, but no known fuel-cycle program to develop a reactor, at least not in the timelines of that SSN program. Meanwhile, PAEC...

OTOH, interestingly, Turkiye is also lining up bilateral uranium investment and mining deals with Niger and some other countries in Africa. This all seems to be outside of the NSG framework, so, we might finally see PAEC gain access to enough uranium to drive indigenous energy reactors (i.e., SMR programs).

Not only that, but the 3 Agosta 90Bs and 8 Hangors are also equipped with ESM equipment. So, in peacetime, we'd have 11 boats (plus other surface and airborne assets) for ELINT, i.e., tracking as many Indian naval vessels and aircraft and their emissions as possible.

In reality you have currently 1 boat on patrol, 2 available in short notice and the other needs a bit of replenishment - The remaining 7 are years off from full strength.

I think what you said MESMA It should be a fuel cell system. It's no more powerful than a Sterling engine,
For example, the fuel cells of the German U-214 submarine can each provide 120KW ，Germany has installed two fuel cells that can cruise at 2-6 knots for 20 days.
China's 039B Stirling engine can provide 110KW thrust，China has installed four Stirling engines capable of cruising at 6 knots for 20 days
In 2015, China reported that the power of the Stirling engine had reached 160KW, if so, the cruising speed will be faster.

Oh, shit, I just checked DeepSeek, so that's what you were talking about.MESMA,It's a French closed-form cycle steam turbine, which even Indians refuse to use, but you think it's far better than Sterling. What are you talking about
