Yesterday when fiddling with AA guns setups for one of my ships i noticed there are 2 6.1" A trips.
One was the well known 6.1" DP gun popular on Yamato, SY and Amagi while the other one had several traits that made it unusual.
- It costs 0 credits.
- Despite being a "A" type gun it requires normal gunners.
- It can hold all types of shells
- Its HE shells have caliber set to 253 (while AP shells have 3 or 4)
- It has stats identical to 6.1" D guns aside of a faster reload.
I don't know how long the gun was in the game but i assume it came in one of the recent patches.
