The KOMZ Gun Camera S-13 was installed in Soviet and Soviet-Bloc fighters and helicopters to record a pilot's success with his machine gun and rocket fire.
Aircraft machine gun camera S-13-300-100-OS (фотокинопулемет / фотопулемет C-13-300-100-OC) 
The camera is powered by 27V DC. Both camera and magazine have a grey hammer metal finish. The camera has a rotary shutter that passes the film gate. The film pressure plate is a sheet of glass with a cross-hair ensuring that the resulting image shows the target accurately. The gun camera was mounted either in the body of the aircraft or in an external photography pod. As the camera did not have to be removed to change the film, harmonisation of the alignment of the camera with the alignment of the aircraft's machine gun or cannon was required only during standard maintenance. In the case of installation in a Mi-24 'Hind' attack helicopter, the S-13 tracked the tractory of rockets carried in weapons pods underneath the port and starboard stub-wings (instead of gunfire).
35mm. The cassette holds 5.2 m of fast (~1000ASA) 35 mm aerial b&w film of type A1000.
The camera S-13 is a fixed focus design that could be fitted with a number of lenses depending on the aircraft it was installed in. On record are:
- S-13 (C-13) 100mm f/6.3 with aperture stops 6.3, 9, 12.5 
- FS-2 (фс-2) 300mm f/4.5 with aperture stops 4.5, 5.6, 8, 11, 16 (firm, audible clicks)

The basic design of the camera remained more or less unchanged since the late 1940s. Starting with the Mikoyan-Gurevich MIG-15, the camera was installed as a gun fire recording camera in a wide range of Soviet and Warsaw Pact aircraft:
- Mig-15 (1949–)
- Mig-15UTI – Training (1949–late 1970s)
- Mig-17 (1951–) 
- Yak-17 (1947– ) 
- Yak-17 UTI (1947– ) 
- -17 experimental (1949) 
- Aero L-29R Delfin (1959–1974) 
and has since then seen modifications for use in other aircraft, including the
In more recent aircraft units, the long-lensed S-13 could be fitted into a camera pod that could be mounted externally
The camera was still in use in 2001 as it is listed as one of skills required of "Repairman Arms" for Belarus According to the website of CDB Photon a subsidiary of KOMZ, the camera system is still in production as Фотоконтрольный С-13А (‘Fotokontrolny S-13A’).

If the GOMZ standard serial numbering system also extended to the S-13/FS-2, then the lens was made in 1981 and the camera in 1982. The camera photographed here was kindly given to me by Siim Vahur (Tallinn, Estonia) who sourced it from a former Soviet airbase in Estonia.
