In what year was the first official naval radio message successfully sent from ship to shore?

The first official naval radio message successfully sent from ship to shore occurred in 1899. This event marked a significant advancement in naval communications, demonstrating the feasibility and practical application of wireless technology in maritime operations.

The message was transmitted by the British Royal Navy's ship, HMS Volunteer, to a coastal station, thus establishing a critical link between vessels at sea and shore-based commands. This 1899 event was pivotal as it laid the groundwork for subsequent developments in both naval and general communication technologies.

Further, the successful transmissions in the years that followed, such as those in 1901 and beyond, while notable, were built upon the earlier achievements of the late 19th century. Thus, 1899 stands out as a landmark year in the history of naval communications.
