Yak-3

Does anyone know what year this type entered service and how did they perform against the Luftwaffe?

The Yak-3 entered service in the Summer of 1944.

It had great success against the Luftwaffe. Some people will claim that the Yak-9U is the better performer, but really they are different beasts. The 3 was a lightweight fighter, that was supposed to have nearly the equal in speed/climb, but better manueverability. The flipside, was that it was a bit more fragile.

It had better roll/turning characteristics. I'd prefer the Yak-3 over the La-7 for Soviet sorties, if they added it...

No, it was not the equal to the Yak9....


The Luftwaffe didn't issue commands to pilots NOT to engage the Yak3 under 15k alt (or so), just the Yak9.

The Yak 3 was underpowered, but was more manuverable, from what I remember. The LW didn't have any problems fighting it (at least not the restrictions placed on fighting the Yak9)

Err, I thought the order was to avoid combat with "Yakolev fighters without an oil cooler under the nose" (paraphrasing here) which covers both the 3 and the 9U

One other thing:

The Yak-9U and Yak-3 both had the Vk-107 engine, yet the Yak3 was a bit lighter. So I don't think it was underpowered.

Maybe you're thinking of the Yak-7?

Sikboy,

No, the wartime Yak-3 had the VK-105 engine.  The Yak-3 with the VK-107 engine was too late to see service in WWII.

According to http://www.wio.ru/tacftr/yak.htm , Yak-3 with VK-107 was too late for WW2 and only 48 were built.

Comparison of Yak-3 and Yak-9U:

Max speed at sea level: 567 / 575 km/h  (352 / 357 mph)
Max speed at altitude: 646 / 672 km/h (401 / 418 mph)
Altitude of max. speed:  4100 / 5000 m (13450 / 16400 ft)
Climb to 5000m (16400ft): 4.5 / 5 min
Turn time: 17 / 19.5 s
Ready weight: 2692 / 3200 kg ( 5930 / 7050 lb )

Yak-3 was much lighter with less engine power,slightly slower, but better climbing and turning.

Yes, German pilots were issued warnings about the Yak-3, before the 9U came around. It's in my Military History of WWII book.

Very nice, and it's only 96 mph slower than this....

(Image removed from quote.)

541 mph ground speed on second leg of world record run... 9 mph tail wind helped.

If it was up to me Holden would get his Yak, and Widewing would get his Bearcat ... I don't think either would be much of a threat since both are unarmed racers. ;)
