Hangor Class Submarine | Updates & Discussion

2000 NM is like 3700 km. Why so less range ?

It is the submerged range, not the surface range.

If you need a nearly unlimited submerged range with inexpensive and operable price, you have to go with the Type 041.

The purpose of the Hangor class submarines is to defend Pakistan's maritime sovereignty in the Arabian Sea.

Got it. Thanks.

By the way what is the final news on Type 041 ? Is it conventional powered or nuclear ?

It's double the range (using AIP) of the 90-B. I think it's excellent.

Range of Hangors​


The range of Hangors is taken from wikipedia page which is obviously wrong. Somebody wrote that range out of their butt without a reference. I have corrected several pages over the time, don't have time anymore to do same thing over and over again.

Agosta 90B, a 90s submarine (much smaller battery & diesel capacity than hangors) has range of 8500 miles.

I don't have exact range for the Hangors but it should be 8,000+ miles. For reference, the Yuan 39B submarine has a range of about 9500 miles.

Since all top class AIP submarines in the world got a range of close to 10,000 nm like Hangor, but this indicator is most likely aligned with its surface range.

While the submerged range will be significantly less.

Realistically, it can submerge at the speed of close to 5 knots without being noisy.

So basically 9 km per hour, then 9 * 24 * 30 ≈ 6000 - 6500 km.

Since an AIP sub has realistically 30 days of endurance without being resurfaced.

A Type 41 can have much longer range being submerged, and can sail much faster underwater without being noisy.

yep that's snorkeling range with its diesel engines on.

The point is 2000 nm range in that wikipage is WRONG as some random guy have put up that number over there and now other blogs also copying same incorrect stats. They do not even mention if its submerged range OR else. When you only say "range" of the conventional submarine, then it usually means its range via its diesel engines which should be minimum 8000 miles plus. Hangors could be anywhere between 8000 to 12,000 miles.

It was probably edited by some Indian or American Wikipedia users.

Hangor with its submerged mode can cover up the entire Arabian Sea and the Northern Indian Ocean.
 
If AIP alone is used, the 90-B has a range of 1,700 kms. It's AIP tech is regarded as the least efficient... ethanol and liquid oxygen.

Hangor uses a Stirling engine AIP which is the most effective. It's range on AIP alone is far more.

The ranges mentioned earlier might be for AIP alone (which will happen rarely).

Just a technical spec... nothing to do with real range.

I haven't studied the new Hangor class in detail. But the Stirling engine is only used for stealth when very near to the target or when trying to avoid detection. Because it generates very low noise..
It's not used for increasing range .

Correct.

I never said it was for increasing range.

Just explaining the numbers quoted earlier. And that those numbers do not matter in real operations and have nothing to do with real range..
