Is There A Chance The Yak 1b Will Be Added?

[SYN_Ricky]

Hang on. Which year is the summer map going to represent?

Only option for a Stalingrad summer map is 1942, as in 1941 the Germans were not there yet, and by summer 1943 the fighting had already shifted westwards again.

Thats what I was thinking too. For a second there I was getting the impression people were expecting the summer of 1943.

The Yak-1B is definitely an upgrade in terms of the rearward visibility and extra armor. Also in terms of firepower with the single Berezin UBS being much more potent than two ShKAS. In terms of speed the Yak-1B at Stalingrad would be the same as the Yak-1 Series 69 that we have already both using the upgraded 105PF engine upgraded from the earlier models that used the 105P as others have mentioned too.

 

The Yak1B was faster then the Series 69. Either at ground level, also at altitude. Reason was the streamlined planeshape. It also had a better climbrate, and a better turning circle. So there would be more enhancements then just the visibility and firepower..

Nope. If anything the razorback shape of the Series 69 is more aerodynamically efficient, because the semi-bubble canopy and cut-down fuselage can create a bit of turbulence immediately behind the canopy. The effect will be slight approaching insignificant though.

 

Any source I've seen for the Yak-1B/Series 69 lists almost exactly the same values for top speed and climb performance.

From what I can gather from this (I don't speak Russian) the numbers for the latest of the 1942 Yak-1s are almost exactly the same as for the 1943 lightened Yak-1B. The B is very slightly faster at sea level (5km/h) and is 10 seconds faster to 5000m. That's less difference than you'd expect between individual aircraft from the same series of Soviet fighters in 1942.

Forget the ones with the stars (***) they are prototyps. The Series 67 according to the russians sources flies 510 at ground level, and 571 at altitude, and needs 6 minutes to reach 5k. The Yak1b with PF engine flies 531 at ground level, 592 at altitude, and needs 5,4 minutes to reach 5k. The only difference in the english source is the ground speed of the series 67 flying 500 instead of 510.

I call that a huge difference. 20 or 30 kph (which source you take) at ground level is game changer.

So let's rather forget about your "nope" up there..

Then we'd be talking Yak-9T, Bf109G-6, etc. Looking into the future I'm assuming we'll move towards spring and summer of 1943 where the available aircraft changes a fair bit despite being only a few months out from Stalingrad.
