• The Type 89 grenade discharger was introduced in 1939, the Type 91 fragmentation grenade was fitted with a propellant base and time fuse.
• As with the Type 10, a threaded socket in the bottom of the body allowed for the attachment of an auxiliary propellant canister for use in a Type 89 grenade discharger.
• This feature was incorporated as part of the Type 91's other uses as a rifle grenade or as a shell fired from the Type 89 grenade discharger, as the long delay enabled longer time-in-flight to distant targets.

• A late example of such a system was the Japanese Type 91 grenade, which could be used as a thrown hand grenade, or fitted with adaptors to either be fired as a rifle grenade or used as a projectile by the Type 89 grenade discharger, a light infantry mortar.
• Introduced in 1931, the Type 91 fragmentation grenade could be thrown by hand, fired from a cup-type grenade launcher ( the Type 100 ), discharged by a lightweight mortar-like projector ( the Type 89 grenade discharger, or " knee mortar " ) . or fitted with tail-fin assembly and fired from a spigot-type rifle grenade launcher.
