As war progressed, Everybody and their uncle carried radar. According to post-war report about Japanese electronics warfare, radars were frequently installed by initiative of repair crew, during vessel maintenance. Most of it was actually some local modification using wire, and some wooden filling, including chair.

Regardless of whether or not Japanese MTBs carried radar of any sort or not, NONE of the ones in the in-game data base have 4 torpedo tubes. The boat in picture #1 is either some designers wet dream or a post war MTB (perhaps produced in Japan) assigned to the JDF.

The first 3 in the data base all have 2 tubes with 45cm torpedoes and ammo set to 2. The last in the data base has 1 tube with a single 63cm torpedo and ammo set to 1.

PT-15 was a post war boat. It was commissioned in 1975. https://www.1999.co.jp/eng/image/10041916/80/1



I don't think the WW2 Japanese Type T-51 MTBs should have a reload. The database is in error. I believe spence is correct. Here is info about the T-51: http://www.ptboatworld.com/PT_Boat_Info ... seMTBs.htm (which states "The boats were armed with three 25mm cannons and two 45.7cm torpedoes." emphasis added) and http://www.navypedia.org/ships/japan/jap_aux_t51.htm .

Here's what you get if you google Type 11 torpedo boat.

8 torpedoes? 113 crew? Big mfer

This is decidedly what would pass as a WWI torpedo boat, not a MTB, or PT. Look at the stats... 544 tons, 269'.

Given the stock database probably aint going to change anytime soon, there's always the editor to use as a fix for something that appears to just be an error.

Yes it appears to be an error, but there are many the database, from too generous range of some Japanese destroyers , from many allied support ships that arrive to early AE Mauna Loa for example. AK and AP's

I would not change it in the editor. Maybe a game design decision.

The designers may have added a little more firepower to balance the game some in late war.
This would make one boat the firepower equivalent of two boats.
That is a reasonable compromise in this type game.

Remember that the boat numbers were scaled way down in the game:

“During World War II, Japan built two hundred forty eight MTBs in fifteen different classes.”

“Of the Type T-51 boats, only nine were completed before the war's end, and another two hulls were left unfinished at war's end.
The Type T-51boats were deemed to be unsuccessful and relegated to being used as what the Japanese referred
to as "Guard Boats" and had two of their four engines removed.”

You have a good game as designed and I would not screw with it.

I would say; don’t try to drive this game towards a simulation, you may screw up the fun factor.

Just my two cents.

What is the best use for mtg or mtb boats? Try to difficult landings or crosses. Any other use?

Disrupting landings (and maybe causing collisions) is their best use. Causing bombardment TFs to use ammo and ops points is the second most useful thing, but you tend to lose some or all of your PTs that way.
IRL they were often used as barge busters, and their crews added 37mm AT guns or 40MM Bofors to their foredeck to outrange the MGs on the barges.
Of course since "Patrol" is part of the boat classification, they can be used to gain info on enemy movements, minefield locations or even weather at an enemy hex you want to attack by air.
Although they carry depth charges, I haven't seen any have success against a sub since McHale's boat torpedoed one on TV.

geofflambert: The Tomozuru (and Otoris) were (without looking it up from memory) post WW1 small destroyers. As most nations went with bigger fleet DDs (with the French and Japanese in the lead) those old "DDs" were re-classified as torpedo boats. In 42 + 43 however their class would again change to "escort" losing a 12cm gun for some more 25mm AA and 4 DC racks, quite usefull ships in that role.

spence: Nice find, I was recently looking up stats of these IJN boats and this detail escaped me. The variants with 45cm torp indeed show a reload. The bigger ones with 65cm not. Problem I see here compared to Allied PTs (which are super annoying and one of their "secret waepons" imho) they have not many guns and the range of the 45cm torp is dismal (2k).

Btw. these ships are also in the shipyard build - when they are ready built will they go to the pool or will they appear like any other ship ready built? I cannot wait for building starting even if only 50% as good as the Allied counterparts...[8|]

I assume the boats that have 6 x old T95 DCs are perhaps good for harbour safety? Has anyone had any success with these? I mean 6 of these outdated DCs will not do anything to Allied subs I guess.
