What are the performance specs for the non-prototype version of the Yak-9U?

No way it will upset arena balance. It will however upset P51 and P38 pilots.

yeah those 190 and 109 guys wont have any trouble with it

la5 will kick yak 9's butt
hehe

you get the idea

bring it on though

I love a good challenge

Yak-9U Production Model

Speed at SL = 357 mph
Speed at Altitude (16,500 ft)= 417.5
Climb to 16,400 ft (5km) = 5.0
Turn time = 20

A plane has never done that to me. It's always been the pilot behind the control stick.

Some (quite a few actually)pilots you could put in a Feiseler Storch with a rifle and they would still give me fits. Others you can give 'em an ME-262 to and even I could still shoot them down.

Citabria, Westy-

Perhaps what I should say is that the Yak-9 doesn't offer the combination of performance/firepower that say, the F4U-1C did when it was introduced. While the Yak's performance (according to the numbers) should be superlative, it will not have an overwhelming gun package. Your rank-and-file pilot won't kill with impunity, they will have to develop marksman skills to make the meager ammo load count.

But let's compare to the 51 and 38. How do either excel above the Yak? It won't be in turn if the wingloading numbers are to be believed. Acceleration? Doubtful. Climb? Nope. 1,500 hp on nearly 7,000lbs loaded means great initial climb and acceleration. As I look at the numbers, the Yak starts to look like a Spit IX you can't run from. The only possible advantage the 51 and 38 might have that I can see is zoom climb. I suppose we'll have to wait and see on that.

Really, my remark was in jest. Funny though, I got the top advocates of the 38 and 51 in one post!

In reality, if you have a good Yak Pilot and good 109, 190, 51, 38 pilot most fights end up in a stalemate. Cause generally those planes will B&Z a yak, and the yak will escape and try to manevour onto your six but you will extend away. This could go on forever had we an endless supply of fuel. But as Leonid said be prepared as you have never seen a plane stall turn like a yak, and I dont wanna hear the famous that plane is hacked statement....YAK's SU Air superiority at it's finest...

Vermillion · « **Reply #38 on:** April 27, 2000, 06:17:00 PM »

Well, the P-51 has a much higher ammo load, can carrying a wide variety of external ordinance, has twice the range, and will outperform the Yak over 25k. Otherwise in a pure air to air role, the Yak is slightly better.

The P-38? Well except for its superiority in the Air to Ground role, if a P-38 pilot spots a Yak-9U he better start praying and rubbing his lucky rabbits foot, if he isn't over 30k ft.

I wonder what the comparison looks like if the P-51 only carries the same amount of fuel as a fully-gassed-up Yak-9U (range was about 500 miles, right). I suspect that the Yak is still the better pure A2A fighter, but at least you're comparing apples to apples at that point.

Bear in mind that the latter VVS iron were built in response to their immediate enemies, the Luftwaffe. Thus, they were designed to outperform their German counterparts at what they did best - Boom 'n Zoom. Granted, it was only within the low to medium altitude range, but combat never got much above 16,000 feet there anyway. So, in a general sense the late-war VVS iron were better E-fighters than the main Luftwaffe fighters (Soviet aircraft were generally more maneuverable horizontally than Luftwaffe fighters throughout the war).

hmm according to gatt´s chart a yak9u with ~6% more wing surface and 25% less power is faster compared to the G10?
grmmpffffff:-)

niklas,
The Klimov 107 inline engine that powered the Yak-9U had a normal maximum power of 1500hp. It's military maximum power was more like 1650-1700hp. I think the Yak-9U's top speed was with military power, not normal power.

a question: what´s the difference between a yak3u and a yak9u?

at http://hep2.physics.arizona.edu/~savin/ram/
i only found something about a yak3u. Did this guy make a mistake, is this the yak9u?
