In transiting situations these Navy ships are not manning CIC, they can’t be. They have 3 radars capable of ‘seeing’ those merchantmen. The surface search radar even has a repeater on the bridge and it has Furuno components… tech that can pick up birds! A vessel so equipped must maintain a proper radar watch. If the plan is that the repeater on the bridge relieves the responsibility of manning CIC then the repeater on the bridge requires a dedicated watchstander… just as a helmsman does not qualify as a lookout, using the OOD as the radar watch is irresponsible. This is all besides the fact that we had dedicated port and starboard lookouts. Every target on radar was relayed to the lookout for visual confirmation or their heads-up. All of those data points that you see on the verbose version of an AIS display, we calculated all of that by hand at the top of every minute, for every target until they were either resolved to be DIW, stationary or clear of us. Info on targets of interest were relayed to the bridge at suitable increments on the 1MC. Nothing ever got anywhere near us without fully knowledge of the watch, Nothing, Ever.
I was on 3 auxillaries during my 5 years on the Navy, 250 to 580ft. We never had a radarman or sonarman assigned, they were all on ships of the line, Gulf of Tonkin. I was an electronics technician but my watch station was a ‘nav’ watch in CIC. We had a 1/4MW surface search radar. '50’s vintage, it had 28 knobs and switches, nothing automatic. Once you became one with the radar you could do anything with it. Watch passenger planes take off from HNL and track them over 100 nm towards the mainland from Lahaina Lake. Pick up a submarine’s periscope long enough to compute her course… more than once. Spot wooden masts 15nm away DIW in the Alenuihaha Channel and tow them back to Hilo… more than once. So, from my perspective, I have no concept of how these M-o-W allow any cargo vessel get anywhere near them, let alone collide with them. That this situation exists aboard these warships constitutes nothing short of gross negligence.
