Type VIIB. Second variant, now the Type VII has a stern torpedo tube.
Type VIIC. The workhorse of the Kriegsmarine. Somewhere in the 500s were built and commissioned until 1945.
Subversion was the Type VIIC/41, which gad much improvements, including better anti air armament, thicker skin for deeper diving and some had radar, schnorkel and more. (The Type VIIC/41 us also my personal favourite). 91 were built, U-995 is the only surviving Type VIIC/41 (also the only one of the Type VII family)
Another subvariant of the Type VIIC was the Type VIIC/42, over 100 were ordered, some were layed down, but those were cancelled in favour of the Type XXI. It would’ve been even more an improvement over the Type VIIC/41.
U-Flak. Type VII uboats modified to carry a boatload of Anti Air weaponry, including 2 × 2cm Flak Vierlings I believe. Could carry 5 pre-loaded torpedoes. Just a few were built/modified, but after some time most were reconverted into normal Type VII Uboats if I remember correctly.
Type VIID. Longer hull, 5 vertical tubes for minelaying, longer hull also resulted in more storage for fuel and food. Also retained the normal torpedo tubes.
And finally Type VIIF. This was the Supply version of the Type VII. It was longer and the heaviest variant of them all. Lacked the deck gun and retained the usual torpedo armament of the other Type VIIs, except for more torpedoes stored, which they could supply to other Uboats at sea when they expended their ammo.
A cool modification for Type VIIC, Type VIIC/41 and Type XXIII Uboats would be the Alberich rubber plating, which helped them becoming less visible on sonar and less noisy. A few of those Uboats were equipped with it, lije the U-480, which was a Type VIIC which sank in a minefield in the English Channel.
Yeah that’s a really cool one. Fun fact the name is borrowed from the dwarf king Alberich, a legendary figure from Germanic mythology who can make himself invisible using an invisibility cloak.
its possibly planned for next year they said that there we “currently no plans to add them to the regular game” but currently is not the same as saying that they will never be added
I hope Gaijin reworks naval detection before/alongside implementing subs. The current spotting system makes it pretty easy to detect your opponents.
The Battle of the Atlantic event’s stealth system was… pretty minimal to say the least. It was really amusing to see that changing course (!) greatly increased your noise radius (obviously your position should have an effect on stealth/detection, but not like that).
The tricky thing will be making the system approachable for new players while still following real-world logic.
Sonar will be unuseable (because of the noise of the ship) if the ship carring sonar drives too fast.I hope Gaijin can make this feature into the game.Then submarines will be less likely to be found unless the enemy slows down , which will make the enemy a big target.
