В общем подправил машинный перевод как мог, но некоторые пункты так и не смог развидеть.

Because the submarine's mechanism has been greatly changed, the U-47 is more adaptable in a single ship attack.

And because of the emergence of u-101, the entire U-boat system has reached the basic 3 gold bottom line to hold the group in the future, while the non-U-boat has to build the boat team or the mixed team around the auxiliary capacity of i-13.

u-101: u-101's own output is the top level, but it is more affected by the enemy ship. Because of the special mechanism of the face, it is equivalent to improve the hit and play a good loss.
But more importantly, u-101 has the ability to attack and defend the U-boat, which is the core of the U-boat team, so the final evaluation of T0.5

i-168: Basically, it is the upper version of i-19. It increases the carrier's special attack and does not say that the violent bomber lightning damage is also much higher.
So give T0.5 evaluation.
The two new gold subs are less than T0 because T0's U-47 and i-13 have higher levels of strategic value and are not limited to pure submarine output capabilities.
i-56: Castration Bars Edition i-19, but in fact the output barely touched a top exhaust, T2 evaluation
U-522: Into the national army in 49 years, if the submarine does not change the mechanism, this stable map strike can ensure the submarine support of the boss battle, but it is not particularly necessary after the revision.
However, there are some uses in the bad activity maps of some map environments, in addition to this is a standard U-boat, T2 evaluation
i-25: There are many functions but they are not used for critical purposes, and the values are not high. In fact, they are somewhat tasteless but better than the T3
whiteboards.
The original T2 i-58 was downgraded to T3, and the submarine's T2 is now not left with a whiteboard level submarine.

London change: top output level and bottom of the patrol survival, It means that she is essentially a heavy patrol gun drive. The main gun is equivalent to a torpedo replacement for her. Compared with Wichita, the ability to attack is actually
worse, but the ability to abuse torpedoes is stronger, and the auxiliary is also used.
She has more competitors, traditional artillery (smoothing and sauerkraut) Newcastle (bombardment aid) Wichita (glass cannon re-patrol) can be considered her specific
competitors.
However, the basic T2 evaluation is the most appropriate. It is obviously too brittle compared with the previous offensive and defensive weight, but it is significantly
stronger than the output and assistance of the following German Bell Val ley.
May have a good play in the Green Sea week.
