Just one ping: WTD 71 revolutionises sonar performance analysis

Gepostet von | 20 Mar 2025 | , , | 0

Submarine hunting is a highly complex business. In order to remain at the cutting edge of technology, WTD 71 is developing a demonstrator for modern sonar performance analysis. Sonar performance analysis is an important tool in submarine hunting and in determining the betrayal range of own submarines against possible enemy detection. It predicts how reliably and up to what distance a potential underwater target can be detected by an active or passive sonar system. In the case of an active sonar system, a sonar ping is emitted at a specific source level. It travels through the water and loses intensity due to various propagation effects, resulting in a loss of propagation. After reflection at the...

The US Navy requires helicopters for a wide range of different missions. The Sea Hawk family is a multifunctional type. During the 1970s, the US Navy was looking for a successor to the ageing Kaman SH-2 Sea Sprite sub-hunter helicopters. The main focus was on the newly developed Light Airborne Multi-Purpose System III (Lamps III), which integrated both air and ship systems. IBM Federal Systems was selected by the US Navy as the main contract partner. As the Sea Sprite was no longer large enough to access marineforum digital+ Are you already a registered user? Now...

Whether in Ukraine or the Red Sea, drones pose a real threat today. In the medium term, laser weapon systems could play an important role in defence against these autonomous small aircraft. When analysing the war in Ukraine and future scenarios, the question currently arises as to how effective lethal defence against unmanned systems and small targets can be achieved. Obviously, guided missiles will not be the first choice for defence against drones in the future due to their high price, and the hit probabilities of artillery systems are low for small targets with access marineforum digital+ Are you already a registered user?

After the Sea Lion, the German Navy is about to introduce the Sea Tiger. An insight into the status of further development of one of the world's most modern naval helicopters. As part of the multinational NATO Helicopter 90 (NH 90) project, a helicopter family in the nine to eleven tonne class was developed for transport and naval missions. The initiators of the development programme were France, Italy, the Netherlands and Germany. Starting from a common basic helicopter, two basic versions were developed, a naval helicopter (NFH) and a transport helicopter (TTH). National helicopter variants were derived from the respective basic versions in order to fulfil specific national requirements. The German Navy operates the NH 90...

Digitalisation leap in marine radio

Digitalisation leap in marine radio

The world of work is changing rapidly through the use of artificial intelligence. There are many opportunities for its use, especially in the maritime environment. Today's "digital" maritime radio systems are a safety-relevant component and feature tried-and-tested, robust technology that works reliably over long distances. They are therefore essential, as mobile radio networks are no longer available just a few kilometres from the coast. However, connection quality varies depending on the distance between transmitter and receiver and the height of the antennas used, and can be further impaired by local weather conditions. Then there is the "noise" of radios and noisy ship operations from propulsion, cooling and ventilation systems...
