Figure 15 Shows the Kollmorgen Photonics Mast System (PMP) and its control console. The PMP is the
AN/BVS-1. It is non-hull-penetrating. Its sensors include infrared (IR), black and white (B&W), color; various
modules can be mounted on the PMP to customize radio sensing capabilities. It is capable of depluming, RAS, and
thermal signature control. The PMP uses a rotary seal and pressure compensation for rotation.

The Sea Sentry is an Unmanned Aerial Vehicle that launches from a canister in the sail and performs ISR. The
wing and tail are folded against the fuselage during storage in the canister and extend to full span during launch.
Figure 16 shows the sea sentry in flight and Figure 17 illustrates launch.

In typical sail arrangements, the radar is located in the forward section and the snorkel is far aft. Masts and
communications equipment are placed between these components. Towed arrays are attached to the trailing edge of
the sail. There is generally space left available for the addition of equipment over the life of the submarine. Figure
18 shows arrangements for four sail configurations – the 688, 688I, Virginia Class, and SSN 21.
