Width of rotating band: 10 mm.
Fuzing: Type 10th year A.A. time (weak).

Type 88 field A.A. gun: Case, 19 9/16 inches.

Remarks: Projectiles designated "Target" in Japanese Army nomenclature are believed to be actual parachute-suspended aerial targets for antiaircraft practice. The drawing and the data given here are from captured documents. Though operation was not described, it is presumed that the time fuze ejects the parachute at the desired altitude and that the projectile body remains attached as weight. The descending parachute then serves as a target for A.A. fire. No ejection charge other than the magazine charge in the fuze is indicated in the document, and the fuze is designated as "weak". It is assumed that this arrangement is intended to decrease the force of explosion to the minimum neces-sary to eject the parachute.

Color marking: Black body, no color bands, the symbol stencilled near the middle of the body.
