Moray program was terminated without a prototype or an order when RDM bankrupt.
Walrus is a pretty good design, on par with equivalent and contemporan western submarines.
Has its goods and its bads.

I heard that the hull of T-212 has a design-flaw making it kinda noisy (especially in the wrong frequence) at certain speeds. Didn’t see it improved on the improved version yet.

Well, on the defence of the UK:
– the boats were brought to fight the Warsaw Pact. With the fall of the communism, they became useless. So it was easier at that time to discard them or sell them then continue to work with them.
– the canadians (especially intern fights between opposition, mainly PQ and the gov at this time) took 10 years to take the decision.
What MoD was supposed to do then?

That was a tread off of course, and some died of it.

There are two papers/books to read on the subject to know it:
– One is Report of the Standing Committee on National Defence and Veterans Affairs, which is online to read.
– The second is the book by Julie H. Furgusson “Deeply Canadian, New Submarines for a New Millenium”.

Compare to what?
What is the purpose of any asset?
To be compared or to do the mission as best as possible?

Would the Scorp do the job better then a 636 or a 212?
Well, who knows? And who cares?
Because two navies don’t have the same exact use (nor training, nor doctrine) for a similar asset.

Smaller fleet have defeating bigger ones all the time in history.
You need one guy who can do things the others won’t dare to, and do it well, and the troups to follow.
That is not because one army has 201 planes that it will beat the one that has only 200, or even 50!

Remeber that japanese army had a 1 to 5 odd when taking Singapore.
In how many days? And they were bad equipped!

No, there are informations.
Need to look for it (and not in PakDef LOL!):

Type 800 was delivered before the first drawings of the 212/214.
If I look at the genealogic tree fo the HDW family, not much links the first to the two others.

You should have made a poll like:

Which is the strongest navy in China’s Territorial Waters:
(o) China’s People Army, Naval Section

Because discussion is useless!

That is why I worry about the Scorps that will be built in India.

Now, I am not sure UK will go to SSK anymore.
They already said they will reduce their force of SSNs (plus I just read the shrinking numbers of T-45s and other stuff).
SSK would be a return to the past, a downgrading.
And a budget for a mixte fleet is not there.

So you will be stuck with less SSNs, but they will (hopefully) have a better disponibility level then the prev. gen.

If you go nuke, you don’t go back.
