Table 13 lists the sail components with their related weight, vertical center, area, outboard volume, and power
consumption rates. The radar system provides navigation and surface surveillance.

The AN/BPS 16 is the latest upgrade to the BPS 15 radar. It is currently used on the Ohio, Seawolf, and
Virginia Class submarines. SSG(X) uses the AN/BPS 16 radar for navigation and surface surveillance. It has a
range of 50 kilometers. The upgrade from the BPS 15 includes a 50 kilowatt frequency-agile transmitter in the Iband.
The AN/BRA-34 mast is used for navigation, communications, IFF, and receiving VLF and GPS frequencies,
two-way HF, and UH.
The OE-315 is a rope buoy system included in every option. It is a towed buoy that operates on the surface and
relays visual images to the submarine while it is submerged at cruise depth. It uses a real-time fiber-optic data link
to transfer images. This system provides the functionality of a periscope without required transit at periscope depth
Figure 13 shows communications capabilities required of SSG(X) operating in stealth, covert, low risk, and
overt modes.
