The U. S. Navy are building at Lakehurst, N. J., the ZR-1 modeled after the Zeppelin L-49. The ZR-1 will be of 55,000 cubic meters (1,940,000 cu. ft.) gas capacity and is intended for use as an experimental and training ship.

Luftschiffbau-Zeppelin is building (August, 1922) at Friedrichshafen a Zeppelin of 30,000 cubic meters (1,059,000 cu. ft.) gas capacity to be used for experimental and training purposes. It will be finished in the winter of 1922-23 and in time to take advantage of some of the worst of winter weather conditions for experiments having to do with airship navigation under the extremes of weather and temperature.

Considerable of the information contained in these pages has been furnished by Luftschiffbau-Zeppelin for which the author is greatly indebted to them.
