FIELD: aircraft engineering.
SUBSTANCE: fire-fighting airship comprises semirigid airframe filled with gas easier than gas . System of power drives, system of propulsors with variable thrust vector, system of ballast, control system, cargo compartments with water tanks, set of device to pumping the water in said tanks and spot water rejection. Said airframe features cigar-like shape. Heat-protection coating is applied on the airframe outer shell. Systems of propulsors and ballast can direct the airframe to vertical position with the help of control system. Water gun is arranged at airframe nose.
EFFECT: minimised windage in heated air upflows.
