Default Why does the shuttle throttle on ascent?

That's one launch out of many Pat. I've seen pictures of a Polaris

Actually if you watch that, it's a salvo launch of two missiles.
And yes, I've seen photos of Polaris coming out of the water at an
angle, then strightning out after motor igniton; in this case the
Trident comes out straight, then pivots over on motor ignition, as it
sets itself on its ascent trajectory at only a few hundred feet in the air.
