A phased-array is an electronically scanned device with active phase shifters at each radiating element. There are non-phased arrays, usually called something like "slotted waveguide array" or "planar array". This is what you will find in the nose of an F-14,-15,-16, or -18. These arrays are mechanically steered. Slightly older vintage fighters use mechanically scanned reflector antennas, e.g. F-4 and F-111. The U.S. does have one phased-array equipped combat aircraft: the B-1B. It has a phased-array with mechanical augmentation.
