Question concerning VVS' Boston A-20 subtypes

[Juha]

Jörg
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.

Juha

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 )

There may some confusions in russian documents because many A-20s were modified in soviet service, notably to reinstall a glazed navigator position in versions which didn't have one (using among others glass panels from Il-4s).

Others were provided with a soviet-made radar,...

That may explain the "appearance" of new subtypes in soviet service.

Hope this can help,

Kolya.

P.S. : I think that on this webpages, the second A-20 photograph depicts such a modified airplane.

there is confusion , but it is not in soviet records.
the confusion comes from us in the west trying to put things into little boxes where they do not belong.
to the Soviets it is simply a 'Boston' not a '-this' or '-that' they really did not care for such record-keeping problems.
the Soviets did make many modifications to the Boston,everything from cold-weather improvements to armament upgrades to bomb racks and torpedo bridges for external ordnance.
your use of the term 're-install' is somewhat misleading as the 'G" model was built for the attack role , not for bombing.
instead the metal panels designed for maintenance access to the four .50 guns were removed and replaced with clear ones, and a navigators station was built in the space where the guns were.
some aircraft were modified with this navigator's station in the rear, some feature glass in the front and rear!

it may have been made in the USSR , but it was a copy of a captured German unit.

Yes , indeed it does !
this plane was an A-20-G35-DO that was converted in the USSR for the anti-shipping role as it was operated by one of the MTAP's (Mine and Torpedo Aviation Regiment)
in the US this aircraft is designated A-20G-36-DO to indicate a Soviet modification to a G-35
this particular plane 'Tallinsky AP' is translated as 'Tallin Air Regiment' and was applied as an honorific.

a bit further research indicates the A-20C actually had four .30 cal guns not.50's
this would make it a lot easier to fit them in the 'cheek blisters'

a bit more research on the aircraft pictured above reveals
it was Manufacturer's Serial Number 15344 and had a fuselage number 2130 (2,130th G built)
it was manufactured sometime between September 1943 and February 1944, I am sorry I cannot be more specific as the data is just not that detailed.
