About
In accordance with the specification of the customer. On the basis of the basic upper stage “Fregat” a number of highly efficient booster blocks have been created. The use of additional fuel tanks and a dropable block of tanks (upper stage “Fregat-MT” and upper stage “Fregat-SB”) at upper stage “Fregat” allowed to significantly increase the mass of refueling and, thereby, increase the efficiency of the upper stage.
