No it isn't. Any warship commanders worth their salts would know what kind of ammunition to use in different situations. Equipping Type 3 shells for all engagements is like using HE shells against both unarmored and armored target ships, sure they'll work, but they're not optimal against the latter. Against non-installation enemies, especially heavily armored ones, AP shell is highly recommended, if not an outright must.
