Page "Paveway" Paragraph 14

The original Paveway series, retroactively named Paveway I, gave way in the early 1970s to the improved Paveway II, which had a simplified, more reliable seeker and pop-out rear wings to improve the weapon's glide performance.

Both Paveway I and Paveway II use a simple ' bang-bang ' control system, where the CAS commands large canard deflections to make course corrections, resulting in a noticeable wobble.

This had relatively little effect on accuracy, but expends energy quickly, limiting effective range.

As a consequence, most users release Paveway I and II weapons in a ballistic trajectory, activating the laser designator only late in the weapon's flight to refine the impact point.
