"No enemy fighter can catch us." The Saiun was a high-performance carrier-based reconnaissance plane - the high speed of its brilliant design ensured no enemy fighter could keep pace with it.
The Saiun flew over the sea reconnoitering enemy movements as the war situation turned grim. The 4th Reconnaissance Squadron, equipped with these very planes, scouted out Leyte during Operation Sho I; afterward, they continued to play an important role as eyes for the 343rd Naval Air Group, which mainly flew the Shiden Kai.
