The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Aeroplanes and Dirigibles of War by Frederick A. Talbot: to 400 horse-power.
So far as the French airships of war are concerned, the fleet is
somewhat heterogeneous, although the non-rigid type prevails.
The French aerial navy is represented by the Bayard-Clement,
Astra, Zodiac, and the Government-built machines. Although the
rigid type never has met with favour in France, there is yet a
solitary example of this system of construction--the Spiess,
which is 460 feet in length by 47 feet in diameter and has a
displacement of 20 tons. The semi-rigid craft are represented
by the Lebaudy type, the largest of which measures 293 feet in
length by 51 feet in diameter, and has a displacement of 10 tons.
