Kawasaki Ki-45 "Toryu" (Nick), 13 Sentai

Today's set of photos feature a Kawasaki Ki-45 "Toryu" (Nick) found by US forces at Cape Gloucester Airfield (Tuluvu) belonging to the 13th Sentai. Some of the photos were contributed by our friend Patrice Fresnel, others are from NARA and the net.

Kawasaki Ki-45 "Toryu" (Nick) flown by the 13 Sentai found at Cape Gloucester (Tuluvu) in January 1944. The aircraft had made an emergency landing, note the bent propeller blades, and then was straffed but otherwise it was in fairly good condition.

As with most, if not all, "Nicks" the rather complicated top camouflage was applied at the Kawasaki factory and therefore it was very neatly painted and was less prone to flaking than those applied at the depots. Note that unlike the fuselage hinomaru, the wing hinomaru do not have a white ring and the camouflage is painted around them. On the fuselage, the hinomaru have white ring and they were painted over the camouflage. 

In this and the previous photo we can see that the port engine is missing but the landing gear is still keeping the plane upright. 

In the belly of the "Nick" a Type 98 37mm Tank Gun, standard equippment of the Type 95 "Ha-Go" Light Tank, was installed. This was a special modification for only a small number of aircraft to give the aircraft some punch against the heavier US bombers. All Japanese sources agree that the particular aircraft was a Ki-45 Kai-Ko.

Unfortunately the Type 98 37mm Tank Gun was hand loaded by the rear observer and therefore its rate of fire was approximately one round every 30 seconds, making it virtually useless during aerial combat. It could deliver a devastating blow against a bomber though. In the photo we can see the gun breech in the observer's position.

The unit's tail marking at the time consisted of a stylized representation of the unit's number "13" comprised number "1" and three bars. The serial number of the aircraft was "1023" and the last two digits were repeated on the tail above the unit marking. In the previous photos the part of the tail marking on the rudder looks darker than the rest of the marking and some artists have depicted it in red, suggesting that perhaps it was a replacement? Nevertheless the camouflage pattern on the rudder matches the rest of the tail and the number "23", from the aircraft's serial number, is painted on the rudder; if the rudder was from a different aircraft it would have a number not matching the serial number. There are many reasons why the canvas covered rudder would look darker than the metal covered parts of the tail.

The formation ceremony of the 13 Sentai was held on March 15, 1938, at Kakogawa Airfield, Hyogo Prefecture.
At that time the unit was equipped with Kawasaki Ki-10 "Perry" fighters but these were soon replaced with Nakajima Ki-27 "Nates".
