The Luftwaffe, the German Air Force, is testing the Twinvis passive radar, developed by the Hensoldt company, in real conditions, to determine its effectiveness and its ability to integrate into the detection device in charge of monitoring the German skies.
In 2019, the passive radar from the German company Hensoldt made the headlines of many specialized sites. Indeed, an article published by the site C4ISRnet.com, renowned for its seriousness, revealed a very juicy anecdote about it, but above all, which concerned the F-35.
Hensoldt's Twinvis passive radar challenges F-35 stealth in 2018
According to the American site, the two F-35As dispatched by the US Air Force and Lockheed-Martin to participate in the Berlin Air Show a year earlier, had been forced to remain in static demonstration on the ground for the entire duration of the show, so even though Berlin had discreetly started negotiations to acquire the device.
In question, a test carried out by the German electronics manufacturer and radar specialist Hensoldt, concerning its new passive radar Twinvis. It would, in fact, have managed to follow the two stealth planes (but probably equipped with radar reflectors to integrate with air navigation), throughout the duration of the transit flight over Germany.
Worse, the American planes would never have been aware of having been detected by this system throughout the flight. And for good reason ! As its designation indicates, the Twinvis is a passive radar, that is to say, it did not emit, of its own, any electromagnetic signal likely to be detected and identified by the fighter's powerful electronic warfare system. American.
Whether or not this detection was at the origin of the absence of a flight demonstration of the F-35 during the 2018 Berlin Air Show, this information made the Twinvis famous, and took Hensoldt for a while, and the technology passive radars, at the forefront.
The Twinvis in service with the Luftwaffe
Since then, it is clear that the German electronics manufacturer has remained rather discreet on the subject, and that he has never repeated this type of resounding declarations, which probably provoked the anger of the United States.
However, the development of the Twinvis has not stopped, quite the contrary. The system and its performance had obviously convinced the Luftwaffe, the German air force.
Indeed, the Twinvis is now operational and tested in real conditions by the Luftwaffe, according to information obtained by the American site Defensenews , during an interview with Lieutenant General Ingo Gerhartz.
According to the German general officer, the objective of the current tests, which would only concern a single system, would be to determine to what extent the Twinvis radar is capable of providing additional relevant information to the detection systems used for monitor German airspace, and in particular be able to detect and track aircraft seeking to go unnoticed by them.
