Yes. There are human beings on the bridge with binoculars, radar scopes, and two sailors whose only duty is to look out for anything that may come close to the ship. Our ships do not sail around on iron mike with the watch officers sitting in the wardroom watching the movie. At least they did not do that in the Navy I sailed with.
Thanks. I could not imagine that human eyes had been dispensed with — neither technology nor individuals can be relied upon 100%, and there always has to be redundancy. The Fitzgerald collision occurred close to the Japanese coast, between major ports. I could accept that the commercial freighter was negligently flying blind, but that does not explain how a USN warship could fail to notice a container ship on course to t-bone them. Truth is in short supply.
