PT boat

PT's always fascinated me.

[castor troy]

what can someone achieve with two depth charges?

[DuckofTindalos]

More than with none. All the major MTB/PT users in WWII equipped their boats with them, and they weren't just for use against submarines, either. Depth charges could just as easily be used against surface ships, for instance to discourage pursuit.

[m10bob]

They are also great for fishing and places to store your beer.
(O.K. now, by a show of hands, how many people did not know a .45 auto comes with a bottle opener?)

"PT crews became adept at scavenging parts and supplies to keep their boats running."

The background behind McHale's Navy?

[DuckofTindalos]

Well, most military units, irrespective of branch of service, tends to magically contain a master scrounger or two...

[mdiehl]

I recall, from something I read at least 25 years ago and have forgotten the source, that one thing the PT boat crews may have done with depth charges is toss them in front of Japanese barges. They're basically deployed by something like a K-gun mount as I recall. It's hard to imagine the DCs being very useful in that role though.

In the solomons some were specifically field modified as barge busters. The torps and DCs removed and replaced with various MGs and automatic cannon.

[DuckofTindalos]

The depth charges on the drawing weren't K-gun mounts; just over the side, same as the torpedoes.

Sink two F-Lighters.

You make a high speed pass by the F-Lighter(barge) (usually in shallow water) roll a depth charge off as you go by, set to a shallow depth (that's why it has to be a high speed pass). The depth charge explodes the compression wave strikes the sea bed and reflects upward to the bottom of the F-Lighter causing it to lift up out of the water thus breacking it back. Result one sunken barge. [&o]

Since the usage of torpedos decreased during the war most PT's discarded the aft two torpedo's and tubes to lighten the boat, the extra weight was replaced with additional automatic weapons for barge busting (a very poor torpedo target). 20mm, extra .50 cal, 37mm auto cannons from old P39's, rockets, 40mm gun, in one case an M16 gun turrent were all added in combination and singularly.

Hi all,

Oh my... wait until "AdmiralLaurent" sees this... he lost number of DDs and CLs against those (and mostly from 20mm and 40mm hits)... [;)]

BTW, and IMHO light weapons on PTs (i.e. the forementiones 20mm and 40mm) should be toned down and their usage against ships much more limited... the DDs and CLs should not suffer tremendous losses from engaging PTs...

I read an account one of a PT dropping it's DC's infront of a JAP destroyer that was in pursuit that was trying to ram them.

Though I actually don't disagree with your statement much the system presently has the aforementioned CLs, etc sinking PTs in droves.  That never happened IRL...something like 7 PTs sunk by IJN naval craft during the entire war.  So the model is more or less "broken in both directions" now to be more bloody (pretty much the norm for all the models).
 
A model where the PTs shoot and scoot (and mostly miss) but don't get hurt much in return would be more realistic but maybe a bit more boring (except for the code writers who would have to get the system to produce those kind of results).

I'd like to see a DD try to ram a PT...if the PT sees it coming, I don't think the DD has a chance.

[Feinder]

I think DDs are too vulnerable to most (actually *all*), "light" weapons.  The problem is, their armor is 0.  And with all weapons in WitP, whether it's a strafing fighter or a PT boat, if the penetration of the attacker is greater than the armor rating of the defender (in the case of DDs = zero), then you take damage.  I think it would be useful to put a little bit of armor on the DDs. 
 
As I understand the rating system, each point of armor generally equates to 1mm of thickness.  I have no idea the thickness of the hull of a DD, but I'd wager it was thicker than 0mm...[;)].  If you set the DD's armor rating at about 5, that's going to make them "mostly immune" to 20mm guns or less (30cal, 50cal, 7mm, 13mm, 20mm).  A 40mm will penetrate.  But you won't have a fighter strafing a DD and putting it out of action on the first pass.

I think fighters -should- be able to damage DDs (at Wake, they even sank one - lucky hit on the DC racks).  But given the constraints of the engine (all or nothing), it's IMO better to make them a bit more survivable vs. the (relatively) smallish weapons.

In my games they never do. I have seen PTs open up with 20mm and 40mm guns but never seen any serious damage from it...just my observations

Edit: in fact in my 3x3 game two squadrons of Dutch and Britt PTs got basically slaughtered by 4 DDs. 7 out of 8 sunk and not a single torp hit on the DDs. I think I may have gotten 1-2 shell hits.

Depending on the surface conditions it shouldn't be able to catch a PT. PTs should be a bit faster and certainly a lot more manueverable...not to mention they fly apart when anything hits it. Get within machine gun range and blast it out of the water.

[DuckofTindalos]

Yeah, PT-109 was more or less an accident. Did the Jap destroyer even notice them?

Do people actually see this in the game? [&:]

I usually set the Dutch fighters to strafe on naval attack to get them experience. I have seen them get lots of hits but never score any real damage on ships.

[DuckofTindalos]

Me either, but then again, the Dutch fighters don't have much firepower. Maybe if we put a Beaufighter on the job...
