At this site:

You'll find:
Objectives of Project Vanguard were: to develop and procure a
satellite-launching vehicle; to place at least one satellite in orbit around the
earth during IGY; to accomplish one scientific experiment; and to track flight
to demonstrate the satellite actually attained orbit.

Vanguard was supposed to be the first US satellite. It lost out to 
Explorer 1. Of course, Sputnik beat them both.
