Hi all!
Some corrections from me. The ANT-12 (I-5) fighter was projected from late 1927 to 1929, not in 1930. It was a counterpart of Polikarpov I-6 prototype. By the order, September 1929 was appointed as its rollout date, but the project wasn't completed. The works were abandoned, and the task was transferred to TsKB-39 NKVD special design bureau (where Polikarpov and Grigorovich created their well-known I-5, first flown at April 29, 1930). But it wasn't the end for ANT-12 project: engineer V. Rodionov suggested to continue project at free time, as a community work. Almost all TsAGI engineers undertook a commitment to work 70 hours free on this project, and it became known at TsAGI as Obschestvennyi Samolet  - "community plane" or "volunteer plane". It wasn't scheduled into official plan of prototype aircraft production, but at December, 1929 the UVVS issued a specification for it. Since then, the aircraft was classified as interceptor fighter and obtained a new official index - I-8 (ANT-13)! So, ANT-12 and -13 are actually two stages of the same project!

The volunteer work resulted in real prototype which was first flown at December 12, 1930 by Mikhail Gromov. The I-8 was tested until April 1932, but wasn't delivered to the official state tests because its performance was worse than required by the specification. Another reason was that I-8 was powered by foreign engine (Curtiss Conqueror).

Now about the ANT-24: it was projected as a bigger version of TB-4 (ANT-16) with four (unrealized) powerful M-44 engines, 2000 hp each, instead of six 830-hp M-34. It was a precursor of giant ANT-26 (TB-6). The TB-4 specification was issued at March 1930, and the first flight was at July 3, 1933. And in March 1932 the production of ANT-26 prototype beginned - it means that design works were already completed. The ANT-24 was only a preliminary design, and I think it could be from early 1931.

ANT-30 (SK-1) was 4-seat "flying cruiser", further development of R-6 (ANT-7) and ANT-21 (MI-3); also a bomber version was projected. ANT-46 (DI-8) was also twin-engined heavy fighter / cruiser, derived from SB (ANT-40), and it was 3-seat; only one prototype was built. See more about both these aircraft at http://www.secretprojects.co.uk/forum/index.php/topic,7951.0/all.html.

Alexander

Great thred! Thanks a lot redstar72 for those clarifications.

Do you confirm there actually was an A.N.T. 41 (T. 1 / LK. 1) prototype in 1936?

Yes, ANT-41 prototype actually existed in 1936; it was first flown at June 2 by A. Chernavsky, but one month ago - at July 3 it crashed because of wing flutter (the crew rescued with parachutes). It looked much similar to ANT-40 (SB) but was notably bigger, with powerful Mikulin M-34FRN engines (1275 hp each) and with large bomb / torpedo bay (6.5 meters length - 40 % of whole fuselage length) suitable for 920-kg TANF torpedo. Its army designation at final stage was T-1 only. Yes, when ANT-41 design began at early 1935, it was proposed as multirole aircraft: not only torpedo bomber, but also "normal" bomber and combat aircraft / flying cruiser, and the last purpose was the main one. In April 1935, the appropriate specification was confirmed by the head of UVVS, Yakov Alxnis, and ANT-41 obtained army index in "LK" category (some sources specify it as LK-1, some others as LK-4 - I can't say which is right). In every case, at 2nd half of 1935 the specification was revised and torpedo bomber become the main role for ANT-41. In accordance with this, the army designation was changed into T-1 (Torpedonosets 1).

Thanks! I've been cross-comparing my files with all that has been shared in this thread, and SURPRISE! I have found a reference for A.N.T. 39...

According to Aviation Magazine #172, the A.N.T. 39 was a 1934 twin-engined fast bomber based on the ANT-29. Possible designations appear as SB. 1 and MI. 13, though TSB. 1 and even AR have also been quoted! The same source gives A.N.T. 40 as SB. 2 ONLY.

Some guy at Aviation Magazine in the 1950s used to be pretty close to someone at Tupolev from what I've heard, so it may be worth considering... What do you say about this, redstar72?

Thanks Stargazer, it's an interesting info. But there are some questions. First of all, it's undoubtly fixed now that army index for ANT-40 was simply SB, without any digits. The popullar names "SB-2" for early production version and "SB-3" for the late one, widely used in literature during many years, both are incorrect. I guess that "SB-2" false index "derived" from the full "long" designation of the aircraft - SB 2M-100, where "2" is only the number of engines - such as, for example, "4" in TB-3 4M-17F. By the same principle, the ANT-57 project (PB 4M-105) is sometimes wrongly mentioned as "PB-4".

The index "MI-13" also looks strange, if ANT-39 was a bomber project: "MI" means Mnogomestnyi Istrebitel - multiplace fighter. Of cource, it could be designation for heavy fighter / cruiser version designed in parallel. But why such a big number? As far as I know, any aircraft designated MI-5 to MI-12 never existed.

And another strange thing: what's the difference between probable ANT-39 and the ANT-40, if the second was also an evolution of ANT-29 concept? (Though ANT-40 was first flown before ANT-29 - such a paradox :) ).

If the Aviation Magazine info had real basis, than it's possible that ANT-39 was a preliminary designation for some early ANT-40 concepts. Also it could be an alternative design from Sukhoi brigade, who worked on ANT-29 (ANT-40 was created by Arkhangelsky brigade). But it also could be a mistake: the authors might define the first SB prototype, with Wright Cyclone radials, as "ANT-39" - while it was also ANT-40.

It is interesting that V. Rigmant wrote in his cycle of articles in "Aviatsia i Kosmonavtika" magazine, that any info about ANT-39 project isn't known.
Best regards,
Alexander

I'm sure the truth will be hidden for many years to come, possibly forever now...

Just one more piece of information from Aviation Magazine: they give the ANT-40 (which they call SB-2) as a derivative of the ANT-39, itself a derivative of the ANT-29.

The fact that they mention turrets as the main characteristic on ANT-40 may signify that ANT-39 could have been used for early prototype work in the form of an airframe WITHOUT turrets. Well, just a theory.

Some more corrections to AM's table.
There were two prototypes of "62" long-range bomber (Tu-2D). But, despite the identical designation, they had some notable differences. The first, converted from production Tu-2 #718, retained standard Tu-2 nose and 4-member crew (the differences from Tu-2 were: enlarged outer wings and vertical tail fins, larger fuel capacity, new propellers and modified pilot's canopy). Its factory tests took place from July 3 to September 23, 1944 (first flight at July 12), official state tests from November 20, 1944 to April 23, 1945. Later it was used for different experiments until 1947, and then was scrapped.

Unlike it, the second "62" (#714) had new longer nose with navigator in prone position and a crew of 5 (the co-pilot was added, his place was behind the commander). It underwent factory tests from October 20, 1944 to March 1, 1945; official tests from July 18 to October 31, 1945. Later, in July 1946, it was converted into a torpedo bomber version called "62T" (factory tests August 2 - September 28, 1946; official tests January-March 1947), and then into "69" (Tu-8) prototype. The "65" and "67" prototypes also were derived from second "62".

The main difference of "65" machine were liquid-cooled Mikulin AM-44 engines (1650 / 1950 hp each) with AM-TK-1B (TK-300B) turbo superchargers. The single prototype was converted from production Tu-2 #201 in May 1946. Its factory tests proceeded from May 21, 1946 until May 6, 1947, but only a few flights were done (the first only at July 1, 1946) - the cause was very unreliable work of turbo superchargers.

The "67" with diesel Charomsky ACh-30BF engines (1500 / 1900 hp each) was also a single prototype (# 402). It was built at November 1945; factory tests from January 15, 1946 to January 2, 1947; maiden flight at February 12, 1946. Neither the "65" nor "67" weren't transmitted to the official tests.

Alexander

The SDB ("63") also existed as two different prototypes. The first was converted from the first "103" (ANT-58) prototype and had only 2-men crew. Its maiden flight was at May 21, 1944. The second, tested from November 1944 to April 1945, was of special built; it was 3-seat and looked closer to production Tu-2. During 1946, this second prototype was converted into Tu-1 ("63P") heavy interceptor.

About Tu-4 (B-29 copy): according to V. Rigmant, 847 were built, not 1000.
