Can the Kawasaki T-4 carry weapons?
The Kawasaki T-4 actually has three hardpoints that can carry weapons
: one underfuselage and two wingpoints (also confirmed here). The possible armament includes gun pods, long-range anti-ship missiles, air-to-air missiles, free-fall or retarded bombs and pods with 70 mm unguided rockets. Hence no way it could be said it cannot be armed.

This aircraft seems more for training but can be used in light attacks.
