3 already existing Aircraft we need for BoM too (LaGG-3 most importantly)

June 18, 2015

All these Aircraft can be adapted to BoM with only a small number of changes in Visual and Flight Model. The Basis for all these has been laid out already in BoS.

LaGG-3 series 1-8

This is the early 5 or 4 gun series.

The main differences are:

1. VK105P/PA instad of PF. Different supercharger Setups with 1020hp T/O, 1100hp at 2000m and 1050 at 4000m. (PF is 1210 at T/O and 1260 at 700m)

Engines are generally tuned for medium altitude combat, unlike later machines.

2. Gun arrangement. -In Blisters on Cowling 2x7.62 Shkas Machineguns with 325 rounds each (650 rounds total)

-In Cowling 1 or 2 12.7 UBS. Starboard gun optional. 220 rounds each

-Through Propeller Hub: Either 12.7 (220) UBK or ShvaK (120)

3. Different profiles of Water Cooler and Oil Cooler. Differ between 1-8 series.

4. Weight: All these are heavier than series 29. Between 3350 and 3280 depending on wether tailwheel is retractable and gun arrangenment.

5. Tailwheel: Early models were retractable. (498kph at SL, 575kph at altitude) but heavier with worse turn.

Non Retractable Tailwheel 4-8 series: (475 kph at SL and 550 at altitude)

6. Rudder: Different or no balancing at all. Uncut fin. Balancing if available is external.

Rates of climb vary between 750m and 600m/minute depending on engine. apparently early models 1-3 outclimbed the later 4-8 series mainly due to installement of the 20 or 23mm cannon and other changes on later ones.

Should be a very good counterpart to Bf109E

Yak-1

Similar to later model except for engine

It's a VK-105P, It has inferior Top Speed at SL (470, 570 at altitude) but better rate of climb. 5.7 min to 5000m against 6 minutes of later model. Engine is tuned for medium altitudes. Carburettors cannot take negative Gs.

Ju-87D-1

Same as D-3, just less armor.

B-models also served in Operation Barbarossa. It was in fact one of the most important Aircraft of this Operation

B- models differ mainly in lower Bombload (500kg), less powerful JuMo 211D of 1200hp, weaker defensive armament of 1x MG17, Different Canopy Design.
