According to the Japanese wiki and some other teitokus, it was believed before that the yellow guns(fukuhou, sub-gun) had a kind of synergistic effect with the red guns(shuhou, main-gun), somewhat like sonars and anti-sub mines, and maybe they actually did, some time before updates. However recently some guys did tests on that combo and found that it doesn't work that way, at least not anymore. The only practical use seems to be when you're trying to limit your damage, so that some other ship won't take away the MVP and the experience from the ship you want to level.
