During 1942 Watanabe designed an ASW aircraft to meet an Imperial Japanese Navy requirement for a specialized aircraft in this category. Designated Kyushu Q1W, this was a cantilever mid/low-wing monoplane with retractable tailwheel landing gear, and powered by two Hitachi GK2C Amakaze 31 radial engines. Operated by a crew of three, the Q1W was planned to use an advanced search radar, but this failed to materialize and instead the Q1W had to make do with an earlier and somewhat ineffective radar complemented by MAD (magnetic anomaly detection) equipment. First flown in September 1943, the Q1W1 was ordered into production in early 1944 as the Navy Patrol Plane Tokai (eastern sea), later allocated the Allied codename 'Lorna'. It proved to be unsuccessful in operational service, too slow and too vulnerable to attack by Allied fighters, and only about 150 had been built by the time the Pacific war ended.

There were 153 built by the end of the war including a small number of Q1W2 variants with a wood construction rear fuselage. There was also one Q1W1-K training variant built with four crew including instructor.

old never heard of & just learned of Kyushu mfg. If this little beauty Q1W Tokai isn't a Ju 88 'homage' nothing is.

Now, if i had good fighter cover, i think i would have enjoyed flying in something as aesthetically pleasing and just plain pretty as this baby.

The Q1Q was the worlds first purpose built anti-submarine warfare (ASW) aircraft.

An aviation enthusiast since 12 yrs. old, this 52 yr. old never heard of & just learned of Kyushu mfg. If this little beauty Q1W Tokai isn't a Ju 88 'homage' nothing is.
