Roscosmos is preparing its response to Elon musk rocket “proton Lite”

Center. M. V. Khrunichev announces the expansion of the product line of launch vehicles (LV) “proton” with upper stage block “breeze-M”. “Medium” and “light” version is planned to run alternately in 2018 and 2019.

-Today in Russia there are no launch vehicles that could be competitive in emerging market segments over the last 4-5 years, ” explains chief designer of launch vehicles, spacecraft Alexander MEDVEDEV. – Offer Center. M. V. Khrunichev will cover those market segments where there are potentially large income and domestic funds are not available.

It’s about the fact that Russia has no missiles “average” capacity and it gives a chance also to Elon musk and other market players to make tangible competition in the market launch of payloads that was a long time ago. But, as you can see, our designers are not sitting idle.

Today the only modification of “Protonproton – M” has three steps. This “heavy” variant, which is far more expensive flying missiles the guise of “Falcon” and not always suitable for launching small satellites.

In the Center of them. Khrunichev decided to “optimize” the “heavy” proton. Here removed the second step and the third lowered at first. This option, as explained “MK” Alexander Medvedev, becomes very competitive in comparison with the “Falcon” taking off from the equator.

Moreover, light-weight there will be two options. The first launch of a two-stage “medium” version of the carrier rocketproton” is scheduled in 2018. This booster will have a standard configuration of RN “proton-M”. This media is used fairing with a diameter of 4 meters. In 2019, the planned start “light” version of proton. This modification will have four engines on the first stage and fairing with a diameter of 4 meters. Both versions will use the upper stage “breeze-M”.

Commissioning of the “light” and “medium” of “Protons” will allow a more effective insertion into the geostationary orbit of space vehicles of light and medium classes.

Comparative load capacity of modifications to the Proton at the exit to geosynchronous transfer orbit with a speed of 1500 m/s:

The PH of the heavy class “proton-M – 6300 kg

The PH of the middle class “proton Average” -5000 kg

Light-class launch vehicles “proton-Lightweight – 3600 kg
