Good Friday afternoon Valin. Only a few more hours left of foolin' to do!

Air Power
Yokosuka P1Y1 "Ginga"

The Allied forces facing Japan in the Pacific War had a number of highly effective fast twin-engined light and medium bombers to choose from. Japan, however, lacked an equivalent aircraft until 1944, the year the Army's Ki-67 Hiryu first saw combat and the Navy received its first examples of the P1Y1 Ginga (Milky Way). Designed by the Yokosuka Naval Air Technical Arsenal and built primarily by Nakajima (with some examples made by Kawanishi), the sparkling performance of the prototype led the Navy to order it into production almost immediately. But the serviceability and reliability of the Ginga right off the production line was very low; thus, it wasn't formally accepted by the Navy until October 1944, and it saw no combat until the Okinawan campaign in 1945.

The Yokosuka Arsenal in 1940 began development of the Ginga to fulfill the requirements of a specification calling for a fast twin-engined bomber capable of making dive and torpedo bombing attacks. The specification was clearly influenced by the Junkers Ju 88 which was just entering combat in Europe, but the aircraft created by Tadanao Mitsuzi and Masao Yamana was no mere copy of the Ju 88. It was a cleanly designed twin-engined airplane with mid-mounted wings on a narrow fuselage of circular cross-section. The proposed engines were twin Nakajima Homare eighteen-cylinder air-cooled radials, which were then in the design stage. With a pair of Homares, the new aircraft was expected to reach a top speed of 345 mph at altitude, and as range was considered all-important for a Japanese land-based bomber, eight protected and six unprotected fuel tanks with a total capacity of 1,218 gallons were to be installed in the wings. Provision was also made for two underwing 48-gallon drop tanks, and oil tanks in each engine nacelle. But armor was restricted to a single 20mm plate behind the pilot's head. The proposed defensive armament was to be just two guns, one in the nose and the other in a flexible dorsal mount; by European/American standards, this was wholly inadequate, and the plane was expected to rely on its speed and maneuverability to escape interceptors. As for the offensive payload, one 1,764-lb. torpedo was to be carried semi-internally under the fuselage, or else two 1,102-lb. bombs were to be carried in the ventral bomb bay.

While the design of the Y-20, as the Imperial Navy designated the prototype, was proceeding, actual production of the new aircraft was assigned to Nakajima. When production of the G3M3 bomber (Nell) terminated as scheduled in February 1943 with the last five examples being rolled out of the Koizumi plant, the G3M3 assembly lines were swiftly dismantled to allow the Y-20 to be built in quantity. The first prototype, powered by a brace of Nakajima Homare 11 engines rated at 1,820 horsepower and driving three-bladed constant-speed propellers, was completed in August 1943. It made its first flight shortly afterward. Both the company's and the Navy's test pilots were enthusiastic about the new plane's high turn of speed and ease of handling in the air, but the ground crews-even the expert mechanics from Nakajima-complained bitterly about the Y-20's troublesome hydraulics and unreliable engines. Even with the favorable conditions obtained during the flight-testing program, the Y-20 was cursed with horrendous maintenance difficulties, and although ordered into production before all six prototypes were built and flown, its formal service acceptance was delayed for thirteen months. Thus, 453 examples were built in all that time, yet they sat idly by while the war situation deteriorated alarmingly for Japan.

During that thirteen-month period, a number of changes and simplifications were made on the assembly lines. The former curved windscreen was replaced by a flatter one incorporating a bulletproof panel, flat-headed rivets were used in the fuselage's construction instead of flush rivets, and the former collector-ring exhaust stacks were replaced by individual stacks to give thrust augmentation. Later production examples also differed from the prototype by having the slightly more powerful Homare 12 (1,825 hp) replacing the Homare 11 (the three-bladed propellers were retained throughout the craft's service life), and by fitting a fixed tailwheel in place of the former retractable one. The prototype Y-20 had a single 7.7mm machine gun in the nose and a 20mm cannon in the dorsal position, but production aircraft had a 20mm gun in the nose, and later, single or twin 13mm machine guns replaced the slow-firing 20mm cannon in the dorsal mount. Very late production aircraft, towards the end of the war, had air-to-surface search radar, and it was also planned to use the P1Y as a mother craft for the Ohka flying bomb, as will be related below.

Finally in October 1944, the Navy gave its blessing to the Y-20, and it became formally known as the P1Y1 Navy Bomber Ginga Model 11

So what are your thoughts on whether or not this was mishandling of ammo or a hit from a Japanese midgit sub?

[snippy_about_it]

Yes, I believe she is, rather was, the AE29 or 26 and she was decomissioned, they held a ceremony and had relatives of those lost on the AE-11 attend her decomissioning.

[snippy_about_it]

The thing that would do me in would be my total lack of patience.

LOL. I'm sorry, I just had to butt in on this post and to laugh at your comment. You are soooo patient yet so antsy. Someday I'll find the words to describe what seems to be a conflict of these two things I admire about you. ;-)

[Professional Engineer]

You can say that again!

[Colt .45]

I would say it was probably more a case of the former, than the latter. Look at the Port Chicago disaster and tell me that sailors weren't lax about what they were dealing with. Of course anytime there is a disaster and the inquiry happens, sailors will always look for other things to blame it on. But the truth is carelessness causes most ordnance mishaps. I know this first hand having survived the USS NIMITZ Flight Deck fire of Nov. 30th, 1988. It was cause by an ordnanceman NOT FOLLOWING proper procedures and taking a short cut.

[snippy_about_it]

Good afternoon and welcome to the FReeper Foxhole.

[snippy_about_it]

Good afternoon Colt .45, it is a reminder that many, many jobs in our services are highly dangerous. We thank you for your service.

[snippy_about_it]

Thanks Johnny. I've never heard of this one before.

[snippy_about_it]

Thanks for your thoughts on this.

[Colt .45]

I know that it is probably not what you wanted to hear, but its the truth.

[Diva Betsy Ross]

Thanks! I have been meaning to stop by for a long time.. I am glad my friend SW pinged me here.

[Valin]

I'm takin the day off!

[SAMWolf]

Thanks Johnny. I wasn't familiar with this one.

[SAMWolf]

Morning DD. Prayers offered for your Father-in-Law, George and the family. Sounds like a feisty guy, good for him!

[SAMWolf]

Hi Diva Betsy Ross. Welcome to the Foxhole.

Nice patriotic screen name. :-)

[SAMWolf]

Morning PE.

This is the USS MOUNT HOOD that came to Portland every year for the Rose Festival

USS Mount Hood (AE 29)
decommissioned

USS MOUNT HOOD was the fourth ship in the KILAUEA class of ammunition ships and the second ship of the fleet to bear the name of the extinct volcano in the Cascade Mountain Range of Oregon. The "Good Hood" as it was called by the ships it served, was deployed to the Western Pacific for the first time on 27 April 1972, and has completed three war-time and thirteen peace-time cruises since that time. MOUNT HOOD was homeported in Concord, CA, and as of December 1999, she is held in reserve at Bremerton, Washington, and is designated a Naval Fleet Auxiliary.

[SAMWolf]

I think he knows everything

I wish! :-)
