France has unveiled new “Seabed Control” where they will have drones, mines, submarines and missile platforms to fortify their coastal defenses out to the bottom of the ocean. This is somewhat like a 21st version of the Atlantic Wall or the Maginot Line. However, the new plan and having military vehicles that can go all …
The US Navy is developing the hypersonic glide body that all the services will use, as well as a booster to launch the Navy’s weapon off a yet-to-be-determined platform. The conventional prompt global strike program has the goal of being able to hit anywhere on earth within one hour. They are developing the cone hypersonic …
After a year-long search, the wreckage of the missing Argentine submarine ARA San Juan (S-42) was found by Texas-based underwater mapping firm Ocean Infinity. The sub was found resting in a ravine about 3,000 feet below the surface, about 323 nautical miles east of Comodoro Rivadavia in the Atlantic Ocean. San Juan’s crew of 44 …

The vehicle is being developed by Generation Orbit Launch Services, Inc. under contract to the Air Force Research Laboratory (AFRL), Aerospace Systems Directorate, High Speed Systems Division. It is an air-dropped liquid rocket, specifically designed for hypersonic flight research to mature …
China has started building a Type 039B (Yuan-class) diesel submarine for Thailand. They expect to deliver it by 2023. It will displace 2,600 tonnes, and have a top speed of 18 knots and can stay submerged for up to 20 days. It will have latest acoustics and electronics technologies, and be able to carry 16 …
Elon Musk has tweeted out short video of underwater tests of the rescue mini-subs. These mini-subs could be used to save 8 boys and their coach who are still trapped in caves in Thailand. Four of the boys were already saved with two buddy divers assigned to each boy. The tests were performed in a …
A team of 90 expert divers – 40 from Thailand and 50 from overseas – has been working in the cave system.

Russia’s new Husky-class fifth-generation nuclear-powered submarine armed with Zircon hypersonic missiles is expected to be built by 2027. The construction will start in 2023 and the first sub will be delivered by the end of 2027. The Husky will feature a two-hull design traditional for the Russian Navy and displace 12,000 tonnes. The submarine will …
Penn State University researchers have made progress on shielding large objects from sound. Chinese researchers have also published substantial progress on cloaking from sound. Both might lead to submarine sonar stealth. Chinese researchers presented the design, architecture and detailed performance of a three-dimensional (3D) underwater acoustic carpet cloak (UACC). The proposed system of the 3D …
China confirms that are testing an electromagnetic railguns on a navy ship. Zhang Xiao, associate research fellow at the Wuhan-based PLA Naval University of Engineering, led a team to develop repeating pulsating direct current power system that could charge the railgun. The same team solved technical issues for shipborne electromagnetic launching systems that will be …
Russia in a speech by Putin claims it has a new nuclear reactor that is 100 times smaller than those used by nuclear-propelled submarines and generates more power. The reactor can also reach its peak power 200 times faster than a conventional nuclear power plant The miniaturization of a nuclear reactor will give Russia another …
