Chromium-plated stealth airship capable of in-flight refueling.

This invention relates to a combined war and passenger airship which, at an appropriate altitude, will be invisible.
The cover is made of chromium metal, which has the power of resisting a pressure of 40 kilogram per □ mm. (25 tons per □") and has a specific gravity of 2.7. It excels all other base metals in resisting oxydation, and is extremely tough. The metal will be highly polished, giving it the reflective power of a mirror.

The bottom of the vessel tapers into a tetrahedron shape. "The reflection of the triangular exterior equalises light and shade; the vessel will therefore always take the colour of its surrounding elements, and consequently, be invisible.

Divided into numerous compartments, with extensive interior framing.

In front of and adjoining the traveling car is a lift or elevating car, suspended by four diverging steel wire ropes. This contrivance fulfils the following purposes:—in war time, the airship can hover over a marine warship and take up from the latter fuel, explosives, or gas, without landing. In peaceful traffic, passengers, mails, ballast, etc., can be taken on board from, or lowered down to, intermediate stations. Hence there will not be any difficulty whatever for the airship to remain in the air for months if necessary. Before the car is lowered, the airship pays out a steel hawser, which is anchored on the land or marine warship. The car is steaded by the diverging wire ropes and can be lowered to a considerable extent without being set in swinging or rotating motion.
