There were two variants of the 10 cm/50 Type 88 naval gun. One variant had a removable barrel liner while the other had an autofretted monoblock barrel. Both variants had horizontal sliding block breaches, hydro-pneumatic recoil mechanism, and Fixed Quick Fire ammunition. They were dual-purpose guns mounted on HA/LA central pivot mounts with a wide range of elevation that allowed the guns to be used against surface and aerial targets. The gun was capable of a theoretical rate of fire of 12 rounds per minute but this was limited to a practical rate of fire of 6 rounds per minute due to the speed of the pneumatic shell hoist.
