but only a concerted effort of science, technology and colonization 

 will produce lasting and significant results. 



Major problems for the Navy are the adaptation of existing 

 ships and equipment to conditions, including extreme cold, for 

 which they were not designed initially, and the maintenance of 

 ship readiness and personnel efficiency while in the high latitudes. 

 New ships and equipment are being designed for extreme climatic 

 conditions in addition to standard and other special requirements. 

 New materials of basic industries (steel, rubber, plastics, textiles, 

 food, petroleum products, etc.) must be developed to replace con- 

 ventional materials, the physical behavior of which becomes modi- 

 fied to the point of unreliability or uselessness at extremely low 

 temperatures. Prevention of icing of upper works of ships and 

 de-icmg of exposed equipment are problems in need of solution. 



Major problems in connection with military aviation in cold 

 weather areas are ground maintenance of aircraft, rapid engine 

 starting, erection of aircraft shelters, solution of manifold and 

 complex materiel problems, prevention of ice formation on air-
