Navy Begins Series of Tests on First Submarine of the Class, Sea Trials Are Expected to Last Until the First Half of Next Year

After being launched into the sea on December 14 of last year at the naval base of Itaguaí, the submarine “Riachuelo” of the Brazilian Navy began its sea trial yesterday (09/25) from the naval base of Itaguaí, in Rio de Janeiro.
The Riachuelo submarine (S40) is the first of four diesel-electric attack submarines S-BR (modified Scorpène class) from the Submarine Development Program (Prosub).

According to the Navy’s schedule, the sea trials will take place until the first half of 2020, and the commissioning of the submarine is scheduled for October 2020.
In addition to the submarine’s equipment being subjected to tests, the Brazilian Navy also plans to launch a heavy torpedo F21 of 533 mm from Naval Group and a mock-up of an anti-ship missile MBDA Exocet SM39 Block 2 Mod 2 during the sea trials.

The Second Hull

ICN, Itaguaí Naval Construction, responsible for the construction of the submarines, has already completed the transfer of the four sections of the second submarine of the series that were built at the UFEM factory, also in Itaguaí.

The sections were the last to be received at ICN, and now the shipyard will begin the final joining phase of the sections aimed at closing the hull of the vessel, which will be named “Humaitá”.

The Second Hull

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

Workers were opening a new road connection near the Marginal Tietê when they found, in the underground of the construction site, remnants of locomotives, wagons, and boilers from the 19th century linked to the forgotten history of Lapa.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

The river that “dies” in the desert never reaches the sea and yet gives life to one of Africa’s largest natural refuges in a truly impressive way.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.
