Alignment between radar track data and launcher coordinates is essential because the interceptor’s guidance relies on a single, consistent reference frame. The radar provides the target’s position and motion in its own frame, while the launcher uses its own position and orientation to execute a launch plan. When these frames aren’t aligned, the system mixes measurements with the wrong geometry, which biases the calculated intercept point, closing velocity, and required tracking guidance. That misalignment means the predicted intercept trajectory is off, reducing the chance to hit and often necessitating recalibration to bring the radar and launcher into agreement. So the main consequence is an incorrect intercept solution that calibration and alignment procedures are designed to fix.

The other ideas miss the point: misalignment does affect launch accuracy because the targeting solution depends on accurate geometry, not something like data link encryption. And it certainly doesn’t improve interception probability; it tends to degrade performance unless corrected.
