I would love a full set of VVS ac................. but sticking the realism hat on and thinking of best return for investment I would go for a full compliment of Yaks (even tho my historical bent is toward Lavochkin)
The Yak is yet to be updated so step one to widening the VVS GPW range would be to broaden the Yak range to equal that of the Spitfire/Bf109/ P40/P38/FW190 et al...........
Looking at the Yak we see this
Yak1 Mid 41 to Mid 43 (razor back unboosted M105)
Yak1b Late 42 to Early 44 (bubble canopy partially boosted M105)
Yak7 Late 41 to Late 42 (razor back converted Yak 1 trainer, unboosted M105)
Yak7b Mid 42 to Mid 43 (razor back, lightened Yak7 partially boosted M105)
Yak9 Early 43 to Mid/Late 44 (bubble canopy version from the Yak7D, partially boosted M105,later versions permanently boosted VK105PF) (D,DD, B variants in the same fuselage)
Yak9T Early 43 to Late 44 (bubble canopy long nosed Yak9 early versions partially boosted M105, later versions permanently boosted VK105PF, 37mm cannon)
Yak9M Early 44 to Late 44 ( 20mm cannon version of the Yak9T permanently boosted VK105PF))
Yak3 Mid 44 to Late 45 (Tsagi development of the Yak 1M {b variant} lightened with slightly shorter wings clear bubble canopy permanently boosted VK105PF)
Yak9U Late 44 to Late 45 (Alloy sheathed Yak9T with troublesome permanently boosted VK107)
Well we are not going to get them all! So which to prioritise!
Looking at the major battles of the GPW, Barbarossa, Moscow, Stalingrad, Kursk, Bagration and (I suppose) Berlin and Manchuria.
We see
Barbarossa Yak1
Moscow Yak1, Yak7
Stalingrad Yak1, Yak7b, Yak1b.
Kursk, Yak1, Yak7b, Yak1b, Yak9, Yak9T
Bagration, Yak9,Yak9T(PF), Yak9M, Yak3
Berlin Yak3, Yak9U
Manchuria Yak3, Yak9U
The Yak1, Yak1b, Yak9T, Yak9M, Yak3, Yak9U Give us a very good spread across the GPW.
The Yak9T, Yak9M, Yak9U all use an extremely similar fuselage. Indeed the Yak9T and Yak9M could be considered the same ac with differing cannon packages.Yak9T/M
The Yak1b & Yak3 use a very similar fuselage albeit the Yak3 has slightly shorter wings and a clear front canopy.
IMO if we could only have 3 Yaks it would be the Yak1b, Yak9T/M, Yak3. If we were granted a 4th the Yak9U comes cheap (we already have the flight model). If we were granted a 5th then the Yak1 would be the start of war hanger queen beside the Hurri IIa and the C202.
