Impressive. Looks like what the Soyuz launcher should have already have evolved into by now. I guess the olive-colored devices on each core are a propellant (kerosene) connection to the pad; where might the LOX connections be?No clear indications of roll control thrusters on the core; perhaps the whole thing stages at the same time?
Liftoff thrust of Angara 5 is similar to Proton, I am not sure how the vehicle can lift more than Proton, unless it is made out some very light materials, and has a really capable upper stage.
Wonderful gallery from wonderful Igor Marinin !!http://novosti-kosmonavtiki.ru/foto/1151/2206/#prettyPhotoBriz-M seems to have a strange serial number... (88801)

(88801)Maybe different serial number and Briz-M version for Angara at Plesetsk?? that is my first guess, otherwise and dev version to test revisions. Not really sure. maybe Manik might have an idea.
Has a "carwash" for Angara payloads been constructed yet?
- Area 35 (launch complex), for Breeze M filling and SC launch. …5.2.7 Integrated LV Handling at the Launch Complex The following work is carried out during assembly of the Angara A3 integrated LV: - Transportation of the integrated LV to the fuel filling station, with thermal control; - Filling Breeze M with propellants; - Transportation of the integrated LV to the launch complex, with thermal control;
