A JGSDF Type 12 Surface-to-Ship missile launch vehicle from the 5th Surface-to-Ship Missile Regiment caught fire 468 meters inside the Kumamoto airport underground tunnel on Jul. 4.
The vehicle was returning to base from the JGSDF Hijyu-dai Proving ground and it was not carrying any live weapons at that time.
The incident forced the tunnel to be closed to traffic for three hours. Two people onboard the vehicle were unhurt.
