Title: Correct Fuel Tanks For P-38L
Post by: Mongoose on January 30, 2016, 04:14:51 PM
   I was looking at the specs for the P-38L (my favorite plane), and I noticed a few discrepancies.

On page 41 of this document:
http://trainers.hitechcreations.com/historical/p-38%2051-127-1.pdf

Internal fuel capacity is listed as 416 gallons.
In AH it is 410 gallons.

The drops tanks have a capacity of 165 gallons.
In AH it is 150 gallons per tank.

Now the 6 gallons of internal fuel isn't going to make much difference, but it would be nice to be accurate.

For the drop tanks, however, that extra 30 gallons could make a difference.

For some unspecified reason Wiki refers to the two US metal drop tanks as 75 gallon and 150-165 gallon.

Yes, but the manual that I referenced, which is not Wikipedia, but the official training manual for the P-38L, says the drop tanks are 165. 

I want my extra thirty gallons!   :x

  Agreed.  But only if the speed restrictions were enforced.

I think the P-38s we have in game are equipped with the sway bracers that allowed the P-38 to drop their tanks at any speed, empty or full.

From a purely game stand point, I would like twin 75 gallon drop tanks.  These may have been used in the early part of the war for P-38s.  Not sure about that.

The lack of symmetry of a single drop tank bothers me for no good reason.

The pilot manual for the P-38D-G models, 01-75F-1, lists 75, 150, and 300 gallon drop tanks on the weight and balance tables.

I wonder if the difference is between Imperial and US gallons?

  150 Imperial gals would be close to 165 Us gals....

I think they made different sizes. The manual specified US gallons.

they had the big 300 gal tanks too and could carry 2,000lbers

Please show me some proof of 300 gallon tank use on combat missions.  I thought they were purely for ferrying.  The 38 rarely carried 2000 pounders.  The risk outweighed the reward according to a 38 driver I talked to who did carry 2000 pounders in the ground attack role in the ETO.  The damage difference from a 2000 pounder and 1000 pounder for the job they did wasn't that much.

I don't have the documentation where I can get it, but I do remember reading that they used 300 gallon tanks on the mission to get Yamamato.  You might start there.

You might as well ask for B-25 bombers on CV's because of the Doolittle raid. Neither one was a typical combat mission.

Guppy research the droop snoot missions. This wasnt done very often due to several reasons but it did happen and they were used. It would be too OP for the game though If they ever do perkie load outs it should be one as well as 1,000lbrs on fighter A/C

1,000lb bombs shouldn't be perked, it wasn't a rare bomb load out.

1000 ponders on the 38 is perfect.  I do wonder how common they were used on the 51.

:airplane: A lot of people are not going to understand this explanation, but knowing you like to know the "nuts" and "bolts" of things, here is something I was told!
You have to remember that these 38's were operating off of un prepared fields of minimum length at best in some cases! The most important "speed" in any twin engine aircraft is the "minimum control speed on one engine"! If you are less than the minimum control speed and lose one engine, you are going to crash if it happens right after takeoff. Yes, the 38 had counter rotating props to counter act the effects of torque and "P" factor, but had no effect on VMC. The "off set" big drop tank added more danger to the pilot when installed! According to some of the manuals I have read on it, if you lose the right engine below VMC, the effect of drag the drop tank produced means nothing because you are going to die anyway! On one engine, below VMC, the aircraft is going to roll over and because of the "moment" arm of the engines, its going to nose down and then, a big fireball, with you as the "marshmallow"!
The effect of the drop tank is that it raises the VMC 8 to 10 knots, depending on which engine quits!

Old question but the 38 didn't carry 75 gallon tanks.  The 165 gallon tanks were designed for the 38.  Later the Jug and 51 lugged them on occasion.

The 38s on that mission carried a specially made 310 gallon tank on one pylon along with a normal 165 gallon tank on the other.  It was anything but a normal combat load.
