thousand feet. The velocity of the larger projectile can also be up- 

 graded to about 300 feet per second, also at water depths to a few 

 thousand feet. This will be done for at-sea testing. During the at- 

 sea test program, propellant with a .074-inch web will be used, the 

 same size as used during the on-land test program. This size web is 

 being used because it is available from stock on-hand and is very near 

 to the chosen web size.
