10. GENERAL DISCUSSION AND QUESTION AND ANSWER 

 PERIOD RELATING TO THE FIRST DAY'S TOPICS 



2/ 

 Donald L. McKernan, Chairmaji, and Panel— 



MR. GLENN R. CARLEY (Naval Ordnance Test Station, Pasadena): 

 What type of acoustic measurements are planned for the expanded 

 system for survey ships? Will they include measurement of the 

 absorption or reflection properties at the bottom? 



CAPTAIN R. D. FUSSELMAN (HO): The subject will be discussed 

 tomorrow by Mr. John J. Schule, Jr. , in the ASWEPS program. 

 A rather active project is under consideration to try and resolve 

 this absorption and reflection problem, but again. Jack Schule will 

 touch on this in a little nnore detail tomorrow. 



DR. RALPH L. ELY, JR. (Research Triangle Institute): Is the 

 free submarine vehicle pictured in the lobby operational or pro- 

 posed? 



CAPTAIN R. D. FUSSELMAN (HO): This is an unclassified pro- 

 ject, and as I mentioned earlier, one of the products that we point 

 to with pride. We were up to New London recently, and the suits 

 of instruments shown are in use in the nuclear boats. 



THE CHAIRMAN: Can you tell us the speed and going power of the 

 free submarine vehicle pictured in the lobby? 



CAPTAIN R. D. FUSSELMAN (HO): I am sorry. I got off on the 

 wrong track. I had reference earlier to the submarine instrumen- 

 tation equipnnent which we have in the lobby. I think this directs 

 itself to the free vehicle. 



This is a torpedo- size vehicle, hopefully being able to program 

 itself over a distance of about 20 to 25 miles, taking a series of 

 successive dives to some 1, 000 or 1, 200 feet, recording the varia- 

 bles in which we are interested to smoke out the oceanographic 

 features between ourselves and the suspected target. It is a joint 

 contract between ONR and HYDRO, and it is barely underway.
