Recently, a research team led by Prof. YANG Jun from the Institute of Acoustics (IOA) of the Chinese Academy of Sciences designed and fabricated a 3D underwater acoustic carpet cloak (UACC) using transformation acoustics. Like a shield, the carpet cloak is a material shell that can reflect waves as if the waves were reflecting off a planar surface. Hence, the cloaked target becomes undetectable to underwater detection instruments like sonar. Continue reading

Below the Radar: Russia’s S-400, S-500 Set to Become Invisible to Enemies

In an age when stealth is the game-changing capability everyone aspires to achieve, Russia’s top-of-the-line air defense systems, the S-400 and the S-500, will receive an upgrade that will allow them to hide from enemy satellites, spy planes and radars, Izvestiya newspaper reported, citing an anonymous source in the Russian Defense Ministry.

The S-400 Triumf with the NATO designation SA-21 Growler and the S-500 Prometey, also known as the 55R6M Triumfator-M, will become undetectable thanks to a special container that will also be used to shield mobile command centers, air defense systems, radar stations and other hardware with complex electronic equipment.

Russia’s stealth ‘black hole’ submarine prepares for 4,000km trip, deep water trials

 

A new Russian advanced stealth submarine, dubbed a “black hole” by NATO for its ability to be undetectable, has begun preparations for deep water tests. However, it must first make a 4,630km journey to the Barents Sea in Russia’s north.

“The crew of the electric diesel submarine Rostov on Don which was handed to the Russian Navy by Admiralty Shipyards has started the preparation for the passing from the Baltic Sea zone to the Barents Sea,” Captain Igor Dygalo from the Ministry of Defense said. Continue reading

Russia to Strengthen Mediterranean Force With ‘Stealth’ Subs

MOSCOW, February 20 (RIA Novosti) – The combat capability of Russia’s naval task force in the Mediterranean will increase significantly following the first deliveries of Varshavyanka-class submarines to the Black Sea Fleet in 2015, Navy Commander Adm. Viktor Chirkov said Thursday.

Russia formed a permanent naval task force in the Mediterranean last year to defend its interests in the region. The move was widely seen, however, as a response to calls for international intervention in the worsening civil war in Syria, Russia’s longtime ally. Continue reading

Russia has launched its new state-of-the-art Novorossiysk submarine, which set sail from a St Petersburg shipyard to become the first of six diesel-electric stealth subs delivered to the Russian Black Sea fleet in the next two years.

The Novorossiysk belongs to the Varshavyanka-class (Project 636), which is characterized by advanced stealth technology, making it virtually undetectable when submerged. Continue reading
