main anchor load line is faked on the side of the launch vehicle base 

 adjacent to the eye in the projectile, secured to the acceleration- 

 activated release mechanism on the side of the base, and extended outward 

 toward the intended direction of major loading (if loading will have a 

 lateral as well as an upward component). The piston retrieval line is 

 faked on the opposite side of the launch vehicle base and may be lightly 

 secured to the launch vehicle or extended to the sea surface. The 

 lengths of these lines may be adjusted to fit the water depth, the 

 mooring design, and the connections to be completed after firing by 

 divers or by remote mating devices. The characteristics of these lines 

 as used at Diego Garcia are given below.
