The (CVN-78), owned by the US Navy, is officially the most expensive warship ever built. It is valued at approximately 13 billion dollars (just over 11.4 billion euros, at the current exchange rate).
The vessel has a sophisticated electromagnetic catapult system (EMALS) and two Bechtel A1B nuclear reactors that generate a . The aircraft carrier has a displacement capacity of 100,000 tons, measures 337 meters in length and It can carry up to 90 aircraft.
However, all this technology is not capable of working if a power outage occurs. According to the Czech media specialized in military and defense information in that emergency situation Signal lights are used to send signals in Morse code.
In fact, in 2017 the US Navy itself confirmed that the aforementioned lights are used, a technology from 1940. In this sense, it should be noted that these signaling lights They are considered highly safe as they do not emit radio signals.. This prevents the enemy from intercepting the waves, which makes it impossible for cyber attacks to occur.
These advantages justify that today There continue to be specific military ranks dedicated to visual signals. In the specific case of the USA, beyond providing specific training and courses in this area, an application has been developed with which you can practice Morse code.
It should be noted that There are a large number of countries thatespecially in emergency situations, They resort to analog techniques. Some examples of this are the navies of other military powers such as United Kingdom, France or Germany. In addition, Russia, China or Iran also use flags and signaling lights if power outages occur.
