Comments, please, if you have real information or experience with such systems? It seems obvious both that the Kitty Hawk knew there was a Soviet sub *in the area* (from contact with the KH's protecting picket ships) and vice versa. WCBS Radio in NYC explained the incident as follows: (1) The Kitty Hawk drug her keel over the sub as the KH overtook the sub from the rear. The sub was rising from a deep dive to periscope depth at the time. (2) The KH didn't know the sub's immediate position because the KH doesn't have sonar gear. (3) The sub didn't know the KH's immediate position because the sub has no sonar detection from her after direction (pickup would be drowned in her own screw noise). The sub's proper procedure before returning to periscope depth or surfacing from a deeper dive (in the Soviet Operations Manual, according to WCBS) is to *turn the boat around* and scan in all directions with the sonar to avoid being hit from its rear blind spot. Apparently the sub's captain failed to follow this procedure. (4) No significant damage was done to either vessel, although if the sub had managed to come only a few feet closer to the surface before impact, she would have been split in two by the KH, killing all 90 of her crew and possibly exposing the area to intense radioactive contamination from her fragile reactor core.
