The HFA is an acoustic “window” used in conjunction with the high frequency sail array.

The primary purpose of an HFA window is to provide an acoustically transparent interface to seawater from the HFA by allowing high frequency acoustic signals to pass through with little reflection or attenuation.

Secondly, the window provides protection to the array from afloat debris and provides smoother conformance to the hull, thereby reducing flow noise.
