Massive boost to French naval capabilities   

Yeah,  I am Norwegian.  This sounds legit, though badly translated.     The reason the warship sank by the way, is because they anchored the ship to land to keep it steady. But it was a poor

More submarine news - the Indian navy forgot to close a hatch on their SSBN: http://www.thehindu.com/news/national/ins-arihant-left-crippled-after-accident-10-months-ago/article22392049.ece

Three days ago a USMC AAV sunk on the sea near San Clemente island, California. It looks like eight marines and one sailor died in the accident with several others being injured (two are said to be in critical condition). So far only one body of those missing was found.

   Not totally warfare, but still interesting. Oceanbird is a concept of wind-powered cargo ship.

 

Quote

   A cargo ship is suitable for transporting large volumes of cargo only using wind energy. At the same time, the dimensions of the vessel will be truly huge. The capacity of such a ship will be enough to transport 7,000 vehicles.

 

   The Oceanbird's main power source will be the computer-controlled 80-meter retractable sails. Computer will calculate how to use wind energy most efficiently. A regular fuel auxiliary engine can be used as a standby and to enter and exit the harbor.

   The maximum speed of the ship will reach 10 knots. It will take about 12 days to cross the Atlantic Ocean. An ordinary modern cargo ship passes this route faster - in 8 days.

 

   To develop the Oceanbird's design, the researchers used a lidar to track the flow of wind over ships at altitudes up to 300 meters. After analyzing the results from 35 million different measurement points, the company's engineers found that the wind speed changes less than expected.

 

   Another important discovery was that not only sails, but also sterns allow to extract wind energy. The team then ran a series of tests using computer simulations and real life scale model tests. The authors of the project wanted to find out with what design it is possible to transport goods across the ocean, using exclusively the force of the wind.

 

   It is noteworthy that the new technology can be used not only in Oceanbird, which has yet to be built from scratch. The wind will work for fossil fuel ships, including cruise ships.

   We'll have to wait a while to see how Oceanbird makes its maiden voyage: the ship's design will be finalized by the end of 2021. The ocean-ready vessel will not appear until 2024.

Ekranoplan "Lun" of project 903 now.

 

   Despite the fact that at the end of July it was towed to the Derbent area, where it was supposed to become an exhibit of the Patriot park, the Lun continues to remain in the same place.

 

   At the same time, as reported by eyewitnesses who visit the site, the ekranoplan is partially filled with water from the damage, making it impossible to implement attempts to pull it ashore with construction equipment.

   Great job, just a great job.
