That's not how the system works. Any firepower exceeding 150 is square rooted, so using any overweight gun on fast battleships reduces all additional bonuses to 80% as all fast battleships can reach firepower cap in parallel with merely 35.6cm guns alone. The Vittorio Venetos are optimal on 381mm Kais instead, and approach the head-on firepower cap.

Unupgraded 41cms will allow Yamato-classes to reach firepower cap in head on, unupgraded 41cms will allow both Fusou and Nagato classes to reach firepower cap in parallel, and upgraded 51cms are needed for Nagato classes to reach firepower cap in head-on. The overweight penalty's magnitude on Nagato classes is identical between this gun and the 46cm, except this has 6 firepower less. The Yamato-classes have neither penalty nor bonus for using either this or the 46cm, but get fit bonuses for 41cms - and they never need to use anything beyond 41cms as they already have max range and firepower cap in head on with just those.

For support shelling where overweight penalties and upgrades don't exist, this provides much less FP than the 46cm triple with no significant accuracy upgrade, making it inferior to using those together with radars.

With overweight penalties as they currently are, this gun is, as Mikan said, the worst heavy gun in existence. If the Yamato class either get a fit bonus from this gun or Nagato class has the overweight penalty for this gun erased, then this gun will have its niche. As it is, it's good for nothing except unlocking the card in the item collection.
