The SF-40 light and heavy and the AF D1 are 3 german coastal vessels at 2.7, and they are ridiculously overpowered. They all have excellent weapons, the SF-40s have ok survivability, and the AF-D1 is a VERY tough nut to crack, and the only thing limiting them is their low speed.
So, lets start with the AF-D1, which is boasting 2 shielded 4x 20mm AA gun turrets, a 37mm autocannon, and 2 shielded 8.8cm flak guns, which compared to contemporaries, is a LOT of gun. It also has very good survivability with 57 crew, shielded weapons, 50mm armor plates around the midship, 25mm armor plates towards the front-middle part, and to top it off, a near indestructible bridge surrounded by 100mm of armor. Its basically a heavy cruiser at that BR.
To compare, the PR191, a soviet “armored” gun boat at that same BR gets 14 crew, armor that will get penned easily by a 50 cal at most ranges, and 2 2x 12.7mm machine gun turrets and a single 85mm gun (tbf the entire soviet coastal tree around this BR is a joke)
Now, on to the SF-40s. For starters, they both have decent survivability and are also slow as shit, but they have amazing armaments (all of which are shielded)
The SF-40 heavy has 2 37mm autocannons and 4 88mm flak guns, and 2-3 88s’ can be fired in one direction at once, which is a shitton of explosives at that tier and that should be able to take out most boats in 1-4 salvoes. The SF-40 light is the SF-40 heavy but with one 37mm autocannon and 4 4x 20mm autocannon turrets instead of flak guns, and this thing can easily create a no-fly zone and also a no-boat without a destroyer damage model zone due to the sheer amount of lead it can piss out.
the light has a insane DPS, and the heavy can easily cripple or destroy most boats with one salvo.
Sure, they are slow and destroyable by torps, but that doesnt matter when you can spray down torpedo boats and planes easily, and just camp in a cap point.
anyways, please move them to at least 3.0. A single one of these things can lock down a entire area and farm the server.
