To reduce drag and therefore improve performance and efficiency.
Airplanes are streamlined in order to reduce drag (coefficient of friction). This allows for less resistance, less fuel consumption, and greater speed.
They are streamlined and have powerful engines.
Their shape and aerodynamic efficiency makes them streamlined.
They are bigger and more streamlined than they used to be.
so that it is streamlined and it can go faster
