why IJN had no PT Boats?

[Onime No Kyo]

The latter. Heck, they couldnt come up with a decent sonar or anything approaching a good areal radar or fire control the prox fuse would be a little outside expectation. When they said they fought with spirit against technology, they wern't kidding.

The Japanese did not use their boats as aggressively as the Americans did and there is very little mention of them in the history books. We originally had about 50 in the Combined Historical Scenario but removed them so we could use the “slots” for more useful ships.

There are still a lot of free slots (2900 - 2999) for Japanese ships, just what are they being saved for?[&:]

How about posting the data for the different Motor Torpedo Boats that were removed![;)]

Being saved for Brady's midget subs and for Shinyos?[;)]

I think your "slot" information is a little out of date:

Using the Ian Allen book as a referance,(Japanese Warships of WW2 by Anthony J Watts),I believe Don is referring mostly to the Japanese "Type T-36",which was apparently the most numerous built of the MTB's built by Japan,(and this book sez all of their MTB's were based on a captured Thorneycroft boat)
The Type T-36 was 23 1/2 tons,59 ft long,2 petrol motors,speed 21 knots,1x13mm or 1x25mm AA gun,2x18in torps,with a crew of 7 men..used numbers 411-450,and 470-473..
The Type T-14 were 15 tons,49 ft long,1 motor ,speed 33 knots(!),1x25mm AA gun,2x18in torps,2 DP launchers..Used numbers 538-555 and 839-848,871-889...
The book lists several other models,but these were the most prolific....
Found this info on page 293,this issue printed 1978....

Oh, thanks Don. However, I'm still ticked that the Japanese don't get proximity fuses.

They couldn't produce a decent infantry rifle, or a good MG. Their artillery sucked, and
so did their tanks. Did you really expect them to master the proximity fuze? Or are
you just speaking tongue-in-cheek?

According to Hara in his book, in his death ride with the Yamato, his CL Yahagi was armed with homing torpedoes, and had proximity fuzes and radar controlled guns (p. 272 Ballantine Books edition.) They also were equipped with bayonets for their eventual beaching off Okinawa so they could stab Americans. Of course, they never made it that far...

BTW, Hara was in charge of training IJN PT forces between his assignment to Shigure and Yahagi. He said [despite whatever the designers had planned] "Insofar as I know, only 200 or so boats, ranging from 15 to 30 tons, were produced under emergency wartime program beginning in 1943." . "All were equipped with aircraft engines, and none could make better than 25 kts. Their V-shaped hulls of wood or steel were 45 to 55 feet overall. Manned by a crew of seven, these boats were armed with two small torpedoes and one 13-mm machine gun. But none ever came up to the standards I would have desired." [p261]. After testing the first of these, he said "This is no torpedo boat. It is nothing but a barge. This scow would be of no real value in a fight"".

Yep....That pretty much matches that Ian Allen book,but the start dates for the Type 36 were a little earlier......

the japanese did have a proximity fuze. one proximity fuze. that is, a single proximity fuze was used in combat. however, it was photo-electric rather than radio, and it was not rugged. it was installed in a bomb dropped on an airfield near war's end. it worked perfectly.
there were no japanese rugged proximity fuzes, so capt hara must be mistaken.
japan got its first mtbs in 1920--four boats purchased from thornycroft. apparently they failed to impress because nothing further was done for twenty years. in 1940, the italian-built h-1 type boat (in japan, h is for mgb and t is for mtb) ran trials with a pair of captured chinese boats (probably wwi leftovers of the italian mas-218 type) and a homegrown 19-ton prototype. the initial conquest of 1941-42 earned a new crop of dutch boats, plus the filipino q111. of all these boats, only this last was more than 20 tons. the japanese made a single attempt to build large boats; these were a knockoff of german s-boats, and they were as bad as any cheap knockoff could be.
the main line of mtb construction centered on the t-1 specification of 20 tons. however, there was not just a single t-1 class, as the scramble for engines led to numerous variants. so when you see classes named t-23 up to t-39, mostly you're just looking at different engines. (t-23 had a top speed of 17 knots.) when you see a figure of 238 mtbs completed by the japanese, it's in reference to this series.
there were also two smaller designs, about 15 tons. and there were more than a hundred h-type boats, plus t-types completed as simple launches. the h-boats could carry torpedoes.

Not for Scenario #15, using version 1.4!

Reviewed stuff on the web, and as far as i can tell, you are correct in this. No indication of proximity fuzes for the IJN.

Sorry, my response to your response to my comment concerning Combined Historical Scenario. Obviously Scenario 15 is unchanged. It is CHS that is out of room.
