Specialists of subsidiaries of the state corporation “Roscosmos” – the Space Center “East” (branch of the center of exploitation of objects of ground-based space infrastructure) and the scientific and production association named after S.A. Lavochkina successfully completed operations to refuel the overtaking block “frigate” with fuel components and compressed gases.
Acceleration unit is transported from a reference-neutralized station building to an assembly and test case of spacecraft to prepare for the assembly of the Soyuz-2.1B rocket.
Overclocking block “Frigate” is intended for the 49th mission as part of a contract with a foreign customer OneWeb with an Eastern cosmodrome. The launch of another party from 36 ONEB spacecraft will be the sixth fully commercial start from the east.
Universal accelerated block “Frigate” was created in NGOs Lavochkina and is intended for use as part of medium and heavy class missiles in order to remove spacecraft to various set orbits.
Basic “frigate” marked the beginning of a whole family of highly efficient acceleration blocks, which are created and created on its basis. The use of additional fuel capacities and a discharged tank block (“frigate-MT” and “frigate-SB”) on an accelerated block “Frigate”) made it possible to significantly increase the mass of fuel refilled and, thereby, increase the efficiency of the accelerated unit.
