| Despite termination of trials in 1951 with the SU derivative
of the MiG-15 featuring paired 23mm cannon on
articulated mountings, the basic concept of gun armament
capable of elevation and depression for air-air use
was persisted with by the MiG OKB. In 1953, flight testing
of a more sophisticated development of the concept
began as Izdeliye SN. A variation of the MiG-17, the SN
was the first fighter of MiG design to feature lateral air
intakes, the 2900kg VK-1A turbojet
being fed via circular orifices against concave fuselage
sides forward of the wing roots. This arrangement permitted
installation of the so-called SV-25 armament
system consisting of a trio of 23mm TKB-495 cannon
mounted asymmetrically (one to port and two to starboard)
on an articulated mounting in the nose section.
Operated electrically, the cannon could be elevated to
27� 26' and depressed to 9� 48', the complete
SV-25 system weighing 469kg. Trials
with the SN were discontinued owing to aiming complexities
combined with advances in air-to-air missiles.

I agree with "bombardier" that this could have become a very interesting aircraft if the true potential of the increased space in the nose had been utilized. reply | bombardier, e-mail, 12.10.2011 16:10 If they had used the space in the nose for a large and powerful radar and not for a complicated pivoting cannon arrangement a very good interceptor would have been born. reply |
