Captain Condor Posted September 3, 2015 Share Posted September 3, 2015 I have seen pictures of an SU-15 with fixed belly mounted cannons in a special mounting. Unfortunately the front of the mounting is missing from the pictures. http://walkarounds.airforce.ru/avia/rus/sukhoi/su-15tm/ds_su-15tm_025.jpg http://walkarounds.airforce.ru/avia/rus/sukhoi/su-15tm/ds_su-15tm_024.jpg Has anyone seen any pictures with the complete installation showing the front fairing?

Lancbuilder219 Posted September 4, 2015 Share Posted September 4, 2015 Same weapon on Fencer aircraft? http://www.google.co.uk/search?q=gsh+23mm&tbm=isch&prmd=ivns&ei=s2fpVfWMMO-V7AaM_5wI&start=20&sa=N#mhpiv=16 Link to comment Share on other sites More sharing options...

The twin 23mm cannon pods fitted on most SU-15s and supplied in the SU-15 kits are much deeper than this installation. Allegedly the fixed cannons were only fitted to very few SU-15s.

Flankerman Posted September 4, 2015 Share Posted September 4, 2015 According to Yefim Gordon's 'Sukhoi Interceptors' (Vol 16 in his Red Star series).......... About the installation of a built-in GSh-23L cannon on the Su-15TM..... The third production example (c/n 0315304) .... was modified for testing this cannon installation ........... The cannon saga continued for almost three years.......... the results were similar to those obtained with the standard UPK-23-250 pods: thus the built-in cannon was recommended for production. Yet the accuracy of the cannon fire was still rather poor because the standard K-10T sight was ill-suited to working with cannons, and, as a specialised gunsight could not be installed due to space limitations, the built-in cannon never found its way to the production line. No photos are provided. Hope this helps Ken Link to comment Share on other sites More sharing options...
KRK4m Posted September 4, 2015 Share Posted September 4, 2015 (edited) So this museum piece is probably a prototype fitted with integral GSh-23L cannon, as known from MiG-21 and -23. Su-24 (and MiG-31) use Gatling-type GSh-6-23 cannon, while MiG-27 has similar GSh-6-30. Edited September 4, 2015 by KRK4m Link to comment Share on other sites More sharing options...
Captain Condor Posted September 5, 2015 Author Share Posted September 5, 2015 Looking at the pictures and at other installations the Mig-23 installation looks the closest. The back of the fairing looks much the same so I will go along with the Mig-23 gun pod and assume the front was also the same. From what I can see of the details they certainly look the same. Thanks for all the suggestions. Link to comment Share on other sites More sharing options...
Captain Condor Posted September 5, 2015 Author Share Posted September 5, 2015 Managed to find the identity of this aircraft. It is the third production SU-15TM (0315304) which was modified to test the installation of the Mig-23 gun pod and is now preserved at Zhukovskiy. The airframe number can be seen on the inside of one of the undercarriage doors. Thanks again to everyone for help. Link to comment Share on other sites More sharing options...
