Torpedo protection level

[linnet]

Hello I have just developed torpedo protection level 4 and am wondering what  the practical effect of each level of protection is and whether I should go for the highest level on all new capital ships,also is there a recommended level for light cruisers and cvl's.Sorry but I can't really see this information elsewhere.

I also would be interested in the practical effects of each level of protection, but that is more to know what research level I should set my Damage Control to rather than what level of torpedo protection I give my ships.

I use as much torpedo protection as allowed for my capital ships, CAs, and CVLs. The reason is that torpedo protection itself is free and only takes up space: you are only paying for the increased weight. And weight is pretty cheap usually. I guess if I had to choose between one or 2 extra planes on a CVL versus more torpedo protection, I'd have to make a tough decision but that hasn't come up for me yet.

For the same reason, I don't put torpedo protection on CLs, because their weight maximum can be better used for other things usually, and they are replaceable enough that being able to build slightly more of them is worth the risk of losing them to torpedoes. Plus, they are naturally harder to hit with torpedoes at least in my experience. However, I would be interested in others' anecdotes if they have successfully used torpedo protection on CLs.

Overall torpedo protection is cheap and it takes only displacement. So I would suggest best torpedo protection if there is no reason to do otherwise. Some reason can be:

- treaty displacement limits

- ship is too small that other system are better choice (usually CL, sometimes CA, CVL)

- shipyards limit (it can sometimes be in case of BB/BC but overall at least I would stick at least with TDS 2 as usually more expensive (displacement) is going to odd TDS level.

note: I would not limit TDS for carries and fast battleships (after 1920)

Thank you for the answers.I assume you need higher protection levels as torpedoes become faster and more powerful through research?Would an old battleship with level one or two protection become too vulnerable at a certain point to use safely?

I think Ludovic's advice on use of TP is very sensible. I myself don't understand how a CL can have the same torpedo protection than a BB, when it depends very much on displacement and beam of the ship to allow protection in depth.

I have made my own rules, although AI of course does not abide to them and really it's a bit cumbersome:

B, DD and KE: no TP ever.

Ships started before 1910: no TP

Ships started 1910-29:
CL, AV: 0
CA, CVL: up to 1
BB, BC, CV: up to 2

Ships started after 1930
CL, AV: up to 1
CA, CVL: up to 2
BB, BC, CV: up to 4

Anyway the idea is that the TP system inbuilt in the game should apply differently depending on the type of ship (allowing for example up to 4TP for a 1940s BB but only 2TP for a CA of the same period)

As far as I can tell, each level of TPS reduces flooding from torpedoes by somewhere between 25% and 50%, and reduces the odds of critical damage by about the same factor. To compensate, there are four torpedo techs that increase damage by an unknown amount (but not nearly enough to fully offset the wonders of TPS4). My personal policy once TPS4 is available is to put TPS4 on all BBs/BCs, TPS2 on CAs and fleet carriers, and TPS1 on any CLs or CVLs that have room for it. Note that TPS3->TPS4 costs almost nothing, so it's usually worthwhile to go all the way.
TPS also slightly reduces flooding from shell hits. You can see the basic formula here.

Thank you for the very helpful replies,I have been playing this game for about six months and find the depth of detail fascinating.

How effective is it to apply bulges to an old battleship/battlecruiser with TPS protection level from 1 to 2?

I do things exactly the same way and it seems to work fairly well.
