Very strange Star,
Even a C 103A -late 1938-was described in the a fore mentioned book..

Very strange indeed. But the strangest aspect of this is that a DB- designation indicates a bomber, so why give it to an aircraft that would be submitted as a transport from the start?? ??? ??? ??? ::)
 
I would strongly suggest that the Douglas C 103 discussed here has nothing whatsoever to do with the Grumman C-103s that were impressed in November 1942. I suggest different sets of designations, with the Douglas C 103 probably being a company designation.
 
Gentlemen , it looks like there is a little misunderstanding here..

"C-103" in this case is not a Douglas nor a Grumman design as such
but the number of an Army AirCorps specification calling for the
development of an experimental attack bomber design and the
construction of a prototype. It was released on 10 September 1938
and replaced by revised specification C-103A on 15 December 1938.

Thanks for clarifying this point! Of course now that you mention it it makes sense, but I've got to say it's a bit hard to understand the numbering systems that the Air Corps and then the Air Force used for its aircraft competitions... The Design Competitions in C-, X- or XC-, the Circular Proposal such as 39-640, the MX- specifications—and even later the Weapon Systems designations starting in WS- ! Wish I could find some serious literature on the subject...

The above is correct, but since I don't read Polish and I'm not the only one, allow me to share the same info from my own Douglas file in English, with a little more detail. You'll also noticed that L+K forgot to mention the R3D-3 designation.

  • c/n 411 was the DC-5 prototype (no known model designation). It was registered NX21701, then NC21701. What L+K forgot to mention is the fact that this too was impressed by the U.S. Navy during the war, as the R3D-3 (BuAer #08005).
  • c/n 422 was to be a DC-5-518 for Pennsylvania Central, but wasn't completed.
  • c/n 423 was to be a DC-5-518 for Pennsylvania Central, but wasn't completed.
  • c/n 424 was a DC-5-510 for KLM on their West Indian routes. At various times of its career it carried the civil registrations PH-AXA, PJ-AIV(-AIW?), PK-ADD, and VH-CXB. In KLM guise, it was christened Wakago. In military guise, it was impressed by the U.S.A.A.F. as a C-110 (s/n 41-424, ater as 44-83231). When damaged, it was finally used for spares for VH-CXC.
  • c/n 425 was to be a DC-5-535 for SCADTA in Colombia, but wasn't completed.
  • c/n 426 was a DC-5-510 for KLM on their West Indian routes. At various times of its career it carried the civil registrations G-AFYK, PH-AXB, PJ-AIZ, PK-ADC, VH-CXC and VH-ARD. In KLM guise, it was christened Zonvogel (which means "sunbird"). In military guise, it was impressed by the U.S.A.A.F. as a C-110, probably as 41-426.
  • c/n 427 was to be a DC-5-518 for Pennsylvania Central, but wasn't completed.
  • c/n 428 was a DC-5-511 for KNILM. At various times of its career it carried the civil registrations PK-ADB, PH-AXE and VH-CXA. In military guise, it was impressed by the U.S.A.A.F. as a C-110 (s/n 41-428). It was apparently destroyed in 1942, though other sources claim it was later later impressed again as s/n 44-83230.
  • c/n 429 was to be a DC-5-518 for Pennsylvania Central, but wasn't completed.
  • c/n 430 was a DC-5-511 for KNILM, registered as PK-ADA. It was then purchased and evaluated by the Japanese Imperial Air Force.
  • c/n 606 was built as an R3D-1 for the U.S. Navy (BuAer #1901).
  • c/n 607 was built as an R3D-1 for the U.S. Navy (BuAer #1902).
  • c/n 608 was built as an R3D-1 for the U.S. Navy (BuAer #1903).
  • c/n 609 was built as an R3D-2 for the U.S. Marine Corps (BuAer #1904).
  • c/n 610 was built as an R3D-2 for the U.S. Marine Corps (BuAer #1905).
  • c/n 611 was built as an R3D-2 for the U.S. Marine Corps (BuAer #1906). Some photos show it sporting the number "152-J-2".
  • c/n 612 was built as an R3D-2 for the U.S. Marine Corps (BuAer #1907).

Please note that constructor's numbers were from the El Segundo system, taken over from Northrop. Aircraft c/n 411 was the first real Douglas aircraft built there, as most of c/n 346 to 410 consisted of Gammas or their A-17/Model 8A derivatives. Also the so-called "model numbers" for Douglas at the time consisted more in contract numbers, the different variants being mostly similar. They worked in a way like North American's charge number (NA-) system or Boeing's hyphenated 7*7-*** series.
 
Some addition to this listing:

1. C/n 422 to 430 were originally ordered by Britain with registrations G-AFYG to G-AFYO.
2. the 1941 serials were applied locally in Australia and are not formally part of the USAAF serial listings. Then, sometime in 1944 the USAAF in Australia decided to send a 'write off note', or something similar to (I would presume) the Pentagon where somebody probably said "oh sh**, we cannot write these off without having them entered into the books" so the three aircraft were serialled 44-83230 (c/n 428), 44-83231 (c/n 424) and 44-83232 (c/n 426) and were probably written off on the same day.
3. c/n 426 eventually ended up in Israel.

Much of this info comes from the work by a John Hopton that I received in hard copy some ten years ago (far too much to scan, so please do not ask!). If there is interest I could, however, extract relevant data from Hopton's detailed lists for these aircraft and make that available through here.
 
Wow! Some worthy addition to the subject, for sure!

Or... you could start work on a book devoted to the DC-5. It has been overlooked by all publishers to this day and I'd love for it to get the profile book it deserves!

Interestingly, I've just found out that my own Douglas constructor's numbers database, elaborated over the years from many different sources, indicates that Santa Monica c/n 2001 was allocated to the DB-4 which is given there as the XBLR-2/XB-19... I know I wouldn't have written it that way if the source had been dubious.
 
Yet some other part of my data contradicts this, since DB-4 also appears next to the DB-280, which was the RCAF Digby I version of the B-18A... So I guess we're back to square one on this question...

Not feasible - would have to rely too much on Hopton's work.

From my dear Stargazer,

and when he talk about the Kaman TD-31,in the same site
I found this;

Model 1242-D was Dougals Sparrow II missile.

True. According to my notes, XAAM-N-3 was the Model 1242C and the AAM-N-3 was Model 1242D.

Hello Stargazer,

thank you very much for calling me "they".
ABCDlist is a one-man thing...me.
The information in your post made quite a few things clear.
I had the serials, just could not match the c/n's.
Having said that, there is one little problem:
You state c/n 3266 - 3360 are BuAer numbers 10956 - 11051.
I'm sorry, but that is not possible: 95 c/n's and 96 numbers.
At this time I have ommited 11051 from my list and that would do the trick.
But I don't know if that is correct, when it is :
than c/n 1892/1912 would be cancelled SBD2-1 09064/09084 (some of your missing c/n's).

Also 2971/3235 could then be identified as a cancelled batch of Douglas BT2D-1/-1Q, to have been BuAer 21742/22006
Cheers,
Peter
 
Hi Peter! Glad to see you on this forum. First of all, congratulations on your website, which has been (and still is) of great help, and certainly helped me made tremendous progress in the early stages of my Douglas c/n listing.

You state c/n 3266 - 3360 are BuAer numbers 10956 - 11051.
I'm sorry, but that is not possible: 95 c/n's and 96 numbers.

It would indeed... but if I'm to trust my listing, it is 10957 that was omitted, and allocated instead to an SBD-5 (c/n 1283). Now that is strange I must admit, since it would be a lone SBD-5 in the midst of an earlier SBD-3/-3A order... There is a mystery here that definitely needs solving.

Stargazer, you're a genius!! ;D
I had BuAer 06546 twice (on c/n's 1283 AND 1314) until now.
I am going to change 1283 to BuAer 10957.
Stranger things have happened to Douglas c/n's in the 1930's and 1940's, so I'm not surprised at all.
It all fits now, thanks.

Cheers,
Peter
 
Douglas Designations: Specifications 400 to 499

Thanks to our fellow forum member Clioman, who got hold of fragments of company listings many years ago, I was able to reconstruct quite a bit of the Douglas designations. Here is what I have in the 400+ range, the most complete slice so far.

NOTES:
1°) DS = Design Specification; TS = Type Specification; GS = General Specification (the difference between these being rather unclear at this point).
2°) Designs that didn't have an company type number such as DC-4 or DB-7 were simply designated by their specification number. Hence the DS-400 specification resulted in the unbuilt "Model 400". Addition of the D- prefix (as in "D-400") was only specified in the early numbers of the list, but is probably implicit here.

My dear Nugo,


nothing called D-1033,but Model-1033.
 
Douglas Model 2085---SOR-182/C-141 competitor proposal.
Douglas Model 2204--- military jetmaster, heavy-lift turbofan transport.
 
Following lark's suggestion, I have attempted to rework existing profiles to portray the unbuilt Douglas DS-262 (Army XB-22), which was to be a B-18A Bolo with the then brand new Wright R-2600-1 Cyclone engine.

As no existing type used the -1 variant, I took the -3 from the Douglas XB-23 Dragon instead.

This is an approximation and should therefore not be regarded as definitive!

Once again hesham I must differ on the use of the D- prefix. Nowhere in the source you mention is that prefix used for these aircraft!

What we have is:
DC-2-124
DC-2-165
DC-2-346
etc.

I do not know of "D-" designations being assigned by Douglas before the 500 series.
 
OK Stargazer,


we can say D,DS or DT,all of them used before "500",and we can also say Model,
but there are a Douglas designations,and Nugo explained before the reason for
that.

hesham, both you and nugo know a lot of things but that doesn't mean you should invent prefixes that do not exist just to make your lists look nicer...
