TsKB - Central Design Bureau - Projects
The aircraft developed in the Central Design Bureau had, in addition to the standard designation of the Air Force, its own, "proprietary". It consisted of the abbreviated name of the organization and the ordinal number of the project to be executed. For this reason, the maneuverable fighter I-15, designed by brigade No. 2, was also referred to in the documentation as CKB-3.
This whole thing is a bit of a mess, since there were at least three distinct entities using the TsKB designator, "the" TsKB associated with TsAGI, and the two numbered TsKB associated with the secret police.
| TsKB-39 (XII.1929 - VIII.1931) only some numbers are known | |||
|---|---|---|---|
| No.5 | LSh | Kocherigin | attack biplane (not finished) |
| No.6 | TSh-1 | Kocherigin | armored attack biplane (Probably TSh-1 is wrong designation. Some documents mean it as “TSh-2 first version”; according to those, TSh-1 was Tupolev ANT-17 project known also as the TSh-B). |
| No.7 | I-Z | Grigorovich | fighter |
| No.8 | TB-5 | Grigorovich | heavy bomber |
| No.9 | DI-3 | two-seat fighter | |
| No.10 | R-5a (MR-5) | Polikarpov | float version of Polikarpov R-5. (Not U-2M / MU-2!) |
| No.11 | MDR-3 | Chetverikov | flying boat |
| No.21 | TSh-2 | Kocherigin | (or “TSh-2 second version) |
| No.23 | ShON | Kocherigin | carrier-based attack biplane |
| No.25 | MBR-2 | Beriev | flying boat |
