The Navy’s underwater drone is the future of submarine warfare

The Navy could theoretically procure many armed Orcas for the price of a single Virginia.

Here’s What You Need To Remember: The Orca isn’t the first underwater drone under construction, and it certainly won’t be the last.

At a military parade celebrating its 70th anniversary, the People’s Republic of China unveiled, amongst many other exotic weapons, two HSU-001 submarines—the world’s first large diameter autonomous submarines to enter military service.

The unarmed robot submarines visibly had communication masts and sonar aperture suggestive of their intended role as tireless underwater surveillance systems intended to report on the movements of warships and submarines of other navies in the Pacific and Indian Oceans.

While the United States may not be the first to operationally drone a Large Diameter Unmanned Underwater Vehicle (LDUUV), it is not far behind with a slightly smaller sub Extra Large UUV. In February 2019, the Navy awarded Boeing a $274.4 million contract to build four (later increased to five) Orca autonomous vehicles, beating out a more elongated and cylindrical design proposed by Lockheed Martin.

New offshore wind energy and transnational grid projects will boost use of submarine power cables

submarine cable market

The worldwide market for submarine electrical cables has surged over the past decade.

Eighty wind turbines are now under construction in the German North Sea.  They will eventually generate enough power for some 400,000 homes. That power will travel via advanced cables buried along several miles of ocean floor, part of a growing move toward undersea transmission of electricity.

The submarine was named after famous independence fighter Yun Bong-gil (1908-1932).

South Korea has launched its fifth 1,800-ton-class attack submarine last week as part of efforts to boost its underwater warfare capabilities against North Korean submarines, the Navy said.The 214-class submarine, named after famous independence fighter Yun Bong-gil (1908-1932) and manufactured by Hyundai Heavy Industries Co., will be delivered to the Navy in late 2015 and commissioned the next year, a Navy officer said.

DeepFlight Super Falcon flying submarine

DeepFlight Super Falcon

The DeepFlight Super Falcon (DFSF) is a sleek vehicle that flies, but it’s not flying in the air, it’s flying through the water. It is shaped like a stout fighter jet with two stubby 8.8-feet wide “wings” at each side, with a super slim chassis and domed semicircle waterproof windows. The 20.11 feet DFSF soars through water instead of simply sinking like traditional submarines. (Video)

China aims for world’s deepest dive in a manned submersible in 2012

The Jiaolong

The Jiaolong reached 16,591 ft in a dive in international waters in the Pacific.

Scientists in China aim to complete the world’s deepest dive in a manned submersible in 2012 by going to 7,000 meters (22,966 ft) beneath the sea after a successful test dive in the Pacific Ocean, state news agency Xinhua reported Tuesday.

Navy prepares submarines for first female officers breaking one of the last gender barriers in the U.S. military

U.S. Navy prepares women for submarine duty.

The biggest concern about serving on a submarine for Ensign Peggy LeGrand is not spending weeks at a time in tight quarters with an entirely male crew. What  really worries her is the scrutiny that comes with breaking one of the last gender barriers in the U.S. military.

Shark Submarine Can Jump 12 Feet in the Air Then Dives Under the Waves

shark submarine 1

The Seabreacher has a top speed of 50mph, seats two people and can jump 12ft from the surface.

As we scud over the surface of the water, the theme music from Jaws is the last thing I want to hear. But inventor Rob Innes begs to differ. He’s playing the tune at top volume over the sound system.  The Seabreacher X  –  co-created and now driven by Rob  –  is the ultimate millionaire’s boy-toy: a James Bond-style craft that can dive under water, roll from side to side and jump 12ft into the air. (Pics and video)

Pedal-Powered Submarine To Go On The Market

Going Green Under The Sea
A pedal-powered submarine capable of diving up to 30 metres has been developed by a Russian company. The craft can be powered by two people with no specialist training and moves at about walking pace.

The pedallers sit side by side in the craft, most of which is made from a special acrylic glass. Its designers say this will give occupants “spectacular underwater views”.

Apart from two sets of pedals, controls are limited to a steering wheel and a few buttons to make operating the submarine as simple as possible.

Shark Submarine Allows Divers A Close-Up View

Hey didn’t they steal this idea from Jaws

Growing up on the beach in Florida, I’ve had my little run-ins with these eating machines.

The most notable of these encounters happened when I was in high school. Summer in Florida demands multiple visits to the beach. In this instance I was body surfing. I saw a slight difference in the current, then felt something like sandpaper scrape against my leg. The both fins broke the surface (the tail fin is level with the dorsal fin-that’s the easiest way to tell that it’s a shark and not a dolphin).

Homemade Soviet-era Russian Submarine

Rub a Dub Dub a post-Soviet Sub

40-year-old Mikhail Puchkov decided to design and build a personal submarine during the stifling era of Leonid Brezhnev’s regime when he was barely twenty years old. He built it secretly in an attic in Ryazan, about 120 miles southeast of Moscow.

“I was not satisfied with the fate that was laid out for me. I wanted to satisfy myself and to have some respect for my life. If I learned to respect myself, I felt it would be easier to find my niche in life. I didn’t know it would work. I just hoped.”

His family, particularly his father, condemned him and his submarine flights of fancy, and the longer the construction took, the more he complained. The first test of the sub came in 1984 and it “sank like a stone,” in Puchkov’s own words, breaking a rudder in the process and setting a climate for the early dives, which were always a bit tense. He said of those times:

Mini Submarines To Explore Human Body Nearing Reality 

 

Ever since the 1966 Hollywood movie, doctors have imagined a real-life Fantastic Voyage  a medical vehicle shrunk small enough to “submarine” in and fix faulty cells in the body. Thanks to new research by Tel Aviv University scientists, that reality may be only three years away.
