It is interesting to read about LORAN in the Korean War. During my seagoing career, we avoided the usage of old LORAN A equipment in coastal waters due to low accuracy and time-consuming procedures. It was OK in the oceans as a substitute for the sextant, especially when satellite schedules were not maintained. (GPS was not available yet, only Transit). Still, I prefered Omega system and its Soviet clone RSDN-20 due to simplicity of the receivers and considered LORAN A boxes just as another layer of redundancy.
Kudos to air navigators who managed to exploit LORAN to its full capabilities in its first generation form.
