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.

only some numbers are known

TsKB-25I-19Polikarpov There were two totally different projects under this designation. The first one was I-16 derivative for Gnome-Rhone Mistral Major (M-85) engine (kind of I-180 precursor; some sources also proclaim it a base for infamous Silvansky I-220). It was projected in mid-1935 but soon cancelled, and the designation was re-used for I-17 version with Mikulin M-34 engine.
