MiG-17 Questions

I’m sure people got tired of the MiG-23/27 thread, but I learned a heck of a lot from it so I was hoping to do the same thing regarding the Fresco.

From what I can tell the MiG-17 (not talking about Polish Lim-5/6 or Chinese J-5/JJ-5 examples) was produced in the following models:

MiG-17 Fresco-A: first production variant with non-afterburning VK-1 engine – some fitted with VK-1A and called MiG-17A Fresco-A

Armament: 2xNR-23 (80 rds. each), 1xNS-37 (40 rds.), two underwing hardpoints for PTB-400 (I guess that’s the right designation as they were 400 litre tanks) tanks or 50/100-kg bombs.

MiG-17P Fresco-B: first radar equipped variant (RP-2 radar) still fitted with non-afterburning VK-1 or VK-1A engine

Armament: 3xNR-23 (100 rds. each), two underwing hardpoints for same stores as Fresco-A

MiG-17F Fresco-C: definitive variant with afterburning VK-1F engine

Armament: 2xNR-23, 1xNS-37, two underwing hardpoints for same stores as Fresco-A

MiG-17PF Fresco-D: radar-equipped model (RP-5) also fitted with VK-1F afterburning engine

Armament: same as Fresco-B

MiG-17PM Fresco-E: radar-equipped bomber interceptor fitted with RP-5 radar and four AA-1 Alkali (Soviet designation RS-2U) AAM’s

Armament: No guns, four AA-1 missiles, two pylons for tanks as on all earlier variants

Now……any corrections to that is great because I’m looking to be accurate on this.

My confusion really lies with the MiG-17F and another variant I’ve heard of all called the MiG-17AS, which apparently was fitted with inboard pylons for unguided rocket pods or bombs. Is the MiG-17AS simply a MiG-17F fitted with two more pylons and still known as Fresco-C or was it a Fresco-A conversion? Could MiG-17F’s be fitted with these two pylons and still be called MiG-17F Fresco-C?

Any and all help is appreciated.
