Angara - Russia's Replacement For The Proton Rocket

Angara is supposed to be Russia's first purely domestic rocket, the rockets developed under the Soviet Union all depended on states other than Russia. Angara was supposed to be a modular design which could scale up to a range of payloads using common Universal Rocket Modules. Except that it's taken almost 25 years to get to a 3rd launch, and we're not even sure if there's a payload on it.
