Whats the difference between these two planes? On the surface they seems completely identical, which one came first and which one is a better?

No their not , they look different and the yak 1 is a bit shorter.

1942: engine is the m105PA
Weapon: ShVAK [120] + UBS [200]
Load: 2 FAB-100
Speed sealevel 478kmph, 4850m @ 563 Kmph
Climb to 5km, 5.9 min
Turn 19 sec
Ceiling KM: 10.4
Ready weight 2883 kg
Range 650Km

Yak 9 1943

1943: engine is the m105PF
Weapon: ShVAK [120] + UBS [200]
Load: none
Speed sealevel 520kmph, 4300m @ 599 Kmph
Climb to 5km, 5.1 min
Turn 17 sec
Ceiling KM: 11.1
Ready weight 2873 kg
Range 650Km

Yak 1 was first to come.
Yak9 is a great Turner BTW one of the best.
I'll choose yak 9 anytime.
The yak9 1943 can turn with the i-16 and Yak3 1944
After an other Yak9 great is the 1943 yak9-T(Yak-9-37)with the same engine and NS-37 [30..32] + UBS [200..220] weapons

The Yak-1 "light" was ecceptional as well.

Interesting! If the Yak 9 is 1943 plane then how come I can fly it in Stalingrad campaign at Sept 1942? http://ubbxforums.ubi.com/images/smiley/blink.gif

he was wrong! the yak9 is a 1942 plane!!

Just as a note, in a book I have called Aircraft of WWII it states that the Yak-9 is essentially a 1942 aircraft while the Yak-1B was not put into service until early 1943. I believe I have seen other sources that state the Yak-1B (sometimes called the Yak-1M) didn't see service until 1943 but I would have to check.

The Yak-9, itself produced in a number of variants, represented the culmination of a highly successful line of single-engined fighters and trainers from the Yakovlev design bureau whose combined production total was some 30,000. It stemmed from the 1-26 prototype of 1938, which became the Yak-l in production in 1940, via the Yak-7, and the machines which acted as Yak-9 prototypes were originally designated Yak-7D1, signifying that they were designed as long-range fighters. They appeared in the first half of 1942, differing from the standard Yak-7B fighter chiefly in making greater use of light alloys. Production began in autumn 1942, and the Yak-9 was in operational service by the turn of the year in the Stalingrad fighting. In 1943 the Yak-9 began to be used as an anti-tank aircraft, being modified for this purpose as the Yak-9T to carry a 37mm cannon or a lighter weapon in the forward part of the fuselage. This was followed in 1944 by the Yak-9K, mounting a 45mm cannon that fired through the propeller shaft. The Yak-9B was a fighter-bomber version equipped to carry a 9921b (450kg) bomb internally, and in 1943-44 the Yak-9D and Yak-9D emerged as variants with their range further increased to provide fighter cover foi advancing troops and for bombing raids over enemy-held territory. One squadron of these. flying from southern Italy after the Italian armistice, provided support for the partisan forces in Yugoslavia, and other Yak-9 variants served with Polish and French units (including the celebrated Norrnandie-Niemen group) fighting in the USSR. The last major version to serve during the war was the allmetal Yak-9U, whose prototype flew in January 1944. This became operational during, the second half of that year and was characterised chiefly by further aerodynamic refinements and the adoption of the new l,600hp VK-107A engine which raised the top speed to 435mph (700kmh). The Yak-9U climbed from sea level to l8,400ft (5,OOOm) in nearly 30 seconds less than the Messerschmitt Bf 109G. The final Yak-9 variant (known briefly as the Yak-Il) was the Yak-9P of 1945. This saw little service in World War 2. but was a standard postwar fighter and fighter-bomber with Soviet air forces, including the North Korean Air Force during 1950-53.

The I-26 prototype

The first fighter designed by Alexander Yakovlev was the Ya-26 Krasavec. This fighter was first flown in March of 1939. Designed to the Soviet fighter requirement issued in 1938, the Ya-26 utilized wood as its major construction material. Determined to be the better of those designs submitted by the various design bureaus, it was ordered into production in as the I-26. Re-designated as the Yak-1, production had barely begun when Germany invaded in June 1941. By October of that same year, all production had been transferred east of the Ural mountains to protect the manufacturing facilities from German bombing attacks. Within 2 months, miraculously, production had actually increased to levels greater than those before the move. Albeit, the level of overall quality would not rise to that level for several more months.
Designed to be as simple to manufacture as possible, while still retaining the robust strength that had always characterized Russian aircraft, the Yak was surprisingly nimble and fast for its generation of design. The Yak-1 had considerably closed the "fighter gap" that existed at the beginning of the Russo- German conflict. The Yak-1 was able to hold its own to some degree with the Bf-109. Never satisfied with almost good enough, the Yakovlev Bureau maintained a constant development program. This resulted in the Yak-1M (see errata notation at the end of the article). This improved fighter had the fuselage behind the pilot cut down and a new cleverly designed semi-bubble canopy was installed which provided for vastly improved rearward vision. What the Yak-1M lacked in sophistication, it made up for simplicity of service. Unfortunately, the little fighter was under-armed although it matched the weaponry of its main rival, the Bf-109F. The -1M was fitted with the Klimov VK-105PF V-12 engine. The original intent was to install the more powerful VK-107 engine. However, due to development problems the Yak-1M was built with lesser output motor.

The Yak-3 was a further development of the Yak-1M.
The yak9 essentially a development of an experimental Yak-7
Yak9-U First flown in December of 1943

"The common designations for Yak-1 fighters used by most Western sources are erroneous in several significant respects. The biggest error is the use of the 1M designation for the "bubble canopy" version of the Yak-1. In actuality, the -1M was an experimental prototype used in the Yak-3 development program, and only a few were built. What most everyone calls a Yak-1M was not really given a separate designation at the time. It was just another Yak-1, and these came in several distinguishable versions themselves. For the sake of postwar discussions, these have come to be known as the Yak-1b, but I think that is only an after-the-fact designation, as indeed so many designations are for Soviet wartime aircraft. During the war the Russians themselves seldom bothered with the same sort of elaborate designations and sub-designations that the other combatants used, other than to sometimes designate major engine changes".
