Afternoon all,
Just thought I'd post this
There have been four lengths of fairings used with Briz on Proton
Elongated fairing
14C75 or 813MITS-9
Length: 13.200mm
Raduga, Gorizont, Ekran-M, AMC9, GLONASS, W3A

14C75 or MITS
Length: 11.600 mm
Nimiq-2, Arabsat-4A
Standard commercial fairing
PLF-BR-15255
813MACL
Length: 15.255 mm
Intelsat-1002, Amazonas-1, AMC-15, AMC-12, DirecTV-8, Anik-F1R, AMC-23, Hotbird-8, Anik-F3, DirecTV-10, JCSat-11, Sirius-4

Length: 13.305mm
Measat-3

Hi Stan, there are more than 4 Briz-M plf´s in my drawings (found on the net) ... but I think there were only used the 4, which you wrote.
The GLONASS-launch in 2003 and the new Raduga-1M used the 11,60m-variant. The older Raduga-34 (launch failed) had the 13,20m-variant.
The newer BR-13305-variant was also used with the Express-AM33-launch.
I also try to identify all the Briz-M-plf´s - for building 3D-models! ;-)
greetings... Soeren

Judging from pictures is difficult apart from angle of the nose.
GLONASS...
The ILS Proton Launch System Mission Planner’s Guide (revision 6 page A-26) lists 14C75 and MITS; 14C75 is long 13.200m and MITS is short 11.600m.
Also there is reference to 14C75 813 MITS-9 on the web, in connection with GLONASS. Is 9 for the length of the cylindrical section?
www.ilslaunch.com/ils/assets/pdf/pmpg_ae.pdf13.200 is no longer listed (mentioned in revision 5) instead 13.305 is now listed.
The 813-M designator on Proton hardware is a design shorthand reference. When an acronym follows the M, it usually refers to the commercial program a certain article was developed for.
The M indicates a Proton-M vehicle.
813-MITS-9 refers to the INTELSAT-IX program (I-903 was launched).
813-MACL refers to the Astrolink program, which never flew, but had some design effort associated. (The C is a Cyrillic S in this case.)
I have only seen these designators on program design documentation and hardware logbooks. I am not sure they are used for anything external to the commercial programs.

Now that makes things a lot more clearer... thanks
Intelsat-9 was originally booked for Proton-M
So 813INT is for INTEGRAL and AST is for Astra!
So what is the Khrunichev designations for the fairings?
Just watching rollout of a Proton, the fairing caught my eye- lots of little bits sticking out all over it, almost makes it look hairy. What is the fairing made of?
Thanks

that is the insulation. It will be removed before flight
