Question concerning VVS' Boston A-20 subtypes

[yogybär]

For my planetable, I'd like to know as exact as possible which A20 the VVS usedPlease have a look at this webpage.

There are several subtypes of A20 mentioned:
1) Boston A-20G, DB-7b
2) Boston A-20G (with guns)
3) Boston A-20G, 10-DÎ
4) Boston A-20G, 20-DO
5) Boston A-20U, A-20Ê

My question is:
What do #1,3,4,5 look like? Do they have no guns in the nose?

TIA!

Hello,
I would recommend you to have a look in my book Red Stars Vol.4 (Lend-lease aircraft in Russia), with almost 100 photos of various Soviet Boston a/c. See the publisher´s web-page http://www.apali.fi/uk/uk.html

For an independent presentation of the book, see eg:

that chart contains a few errors. mostly in letter-designations for the different models.
this is compounded by translation errors from American to Russian.

A-20B's and A-20C's had 2 .50 cal guns in the 'cheek' positions
the A-20G-1 had four 20MM cannons and the .50's
the A-20G-5 had four .50 cal in the nose plus the two in the 'cheek'
this remained unchanged for the rest of the 'G' types
the A-20J and K were again glass nose planes with the two 'cheek' .50 cal
did you want to know about rear armament also ?

Thanks, Kurlan!

So would you interprete the table like this:
1) Boston A-20C
2) Boston A-20G 4x20mm
3) Boston A-20G 4x.50
4) Boston A-20G 4x.50 + 2x.50-turret
5) Boston A-20J&K glass nose + 2x.50-turret

My task is to split all A-20 in the subtypes 1) and 4) as fair as possible for online wars based on Il2-game.

Do you also know when A20G was first used in VVS? I estimate early '44...

Carl, I'd love to buy all RedStar-books, but money's a topic at 50Euros/book... "Jagdwaffe" i.e. is there for ca. half the price.

IIRC A-20G-1 4*20mm + 2*.50 in nose and 1*.50 in dorsal position + 1*.30 in ventral tunnel
A-20Gs from G-5 to G-15 6*.50 in nose and 1*.50 in dorsal position + 1*.30 in ventral tunnel
A-20Gs from G-20 onwards 6*.50 in nose and 2*.50 in dorsal turret + 1*.50 in ventral tunnel
A-20J & K 2*.50 in nose and 2*.50 in dorsal turret + 1*.50 in ventral tunnel

And IMHO that was also what Kurlannaiskos wrote.

OK, we are in consens apart fro mmy names' spelling: "Jörg", not "Jörk" .

I'll put all J&K into the A20C-group in my table.

I'm terrible sorry for my typing error!

BTW I don't know if this have any relevance to You but late Js and all Ks had the ability to carry extra 2000 lbs of ordanance externally, i mean that over the normal 2000 lbs internally.

actually that was the H and the K.
they both featured a slightly more powerfull engine than the G an J
R-2600-39 instead of the earlier R-2600-23
1,500 hp or 1,700 for take-off (as opposed to 1,350/1,600 for the -23)
the A-20G were in production from Feb 43 to Jun 44
as to when thay actually started service with the VVS ....a bit more complicated.
you would need regimental records or ones from the ZAP's
(Ferry Regiments)

to yogybar ;
I don't think it is fair to group these aircraft together that way.
the Soviets recieved more 'G' models than any other so to simplify matters you could probably just list the G and leave the others out for now.
(to be added at a later date ???)

Juha, no problem... I also do typos way too often.

At least the earlier one will definitely come into the "A20C"-group, if such a plane is in the Sim.

Concerning J&K: I think, the "A20C" will have the usual super-real bombloadouts of PF and thus, it would fit well apart from the turret and better engine. What would you propose for the J & K?

grouping the A-20G-5 and -10 in with the A-20C actually makes some sense ; I forgot to mention earlier that the A-20C also has two .50 cal guns in 'blisters' mounted outside the 'cheek' positions so these aircraft (A-20C,A-20G-5,A-20G-10) all had four .50's in the nose and one flexible .50 in the rear (G) or two .30 (C)
I don't know if the difference in 2 X .30 vs. 1 X .50 makes a difference in your sim.
th only other difference would be the nose ; the C is a glass nose and the G is a 'hard nose' (no glass)

as for the J and K the only difference is in the more powerfull engine on the K. (same engine on the H )
