PREFACE 



The TRIESTE program is presently administered under 

 BUSHIPS problem number S-R004 03 01, Task 052 8 (NEL 

 L4-2). Support for fiscal year 1960 was provided by the 

 Office of Naval Research, and for fiscal years 1961 and 1962 

 jointly by ONR and BUSHIPS. The technical and operational 

 control of the program was assumed by BUSHIPS in August 

 1959. 



The report covers work until the end of calendar 1961, 

 and was approved for publication 27 July 1962. In the future, 

 it is planned to issue annual reports to cover successive 

 fiscal years. 



The author wishes to thank Dr. G. H. Curl, Dr. A. B. 

 Rechnitzer, CDR R. D. Plunkett, and LT L. A. Shumaker
