Designation system of Gorky aircraft plant No.21 (USSR)

[AM]

The Gorki aviation plant No.21 (now - Open Society "the Nizhniy Novgorod aviabuilding plant "Sokol") used accurate enough system of designations of production: types. Types of planes of factory No.21 are used to distinguish updatings Polikarpov I-16. Though the designation "I-16 type 24" is actually a mix of two designations: official "I-16" and intrafactory "type 24".

The plane type is used in serial number. For ГАЗ-21 serial numbers have the following appearance:

NN21SSPP​

Where
- NN - an type (article) number, one or two figures
- 21 - aircraft factory number
- SS - series number
- PP - plane number in a series

Hi all!
The Type 16 and Type 23 were also I-16 versions. Type 16 was a version with two synchronized 12.7-mm ShVAK machine guns - three prototypes were built (I posted a bit more info here). The designation Type 23 was used since April to August 1939 for the I-16 armed with ten RS-82 unguided rockets; later this weapon became standard and the special designation was cancelled.

The Type 11 wasn't attack version of the I-16, but another trainer version - UTI-3 with Nazarov M-58 engine (single prototype built in 1935: see here).

The Type 21 was firstly assigned to unbuilt I-16 version with four synchronized ShKAS machine guns, later reassigned to Pashinin fighter. The Type 22 was another unbuilt I-16 version, also with four synchronized machine guns but just two of them were ShKAS - the other two were Savin/Norov SN with even higher rate of fire (the same weapon was used on Type 19).
