HMS Vigilant officers threatened to resign over affairs
News Media


Published on Oct 8, 2017
HMS Vigilant officers threatened to resign over affairs on board nuclear-armed Royal Navy submarine by captain and his second-in-command.
Five officers on board a British nuclear-armed submarine have threatened to resign amid reports of a love scandal involving the captain and his second-in-command.

HMS Vigilant was submerged below the North Atlantic when reports of the high-ranking submarine officials having sexual relations with two different women emerged - something which is forbidden between two serving personnel on the same vessel.

The incident came to light after a member of the crew alerted senior officials at the vessel's base in Faslane, near Glasgow.

UNDERWATER EXPLOSIVES & ANTI-SUBMARINE WARFARE U.S. NAVY FILM "CLOSE IS NEAR ENOUGH" 52084
PeriscopeFilm


Published on Feb 16, 2017
This “unclassified” 1974 US Navy film opens with a German submarine crew silently stalking and then firing upon an Allied vessel. During WW2, the film says, 47 major ships, 52 submarines, and countless lives were lost. The war also taught the Navy that close exposure to an underwater blast can severely damage a ship’s hull or propulsion systems, putting it out of commission. The film’s title, “Close Is Near Enough,” appears on the screen at mark 03:20 as the narrator echoes those same words. For this reason, the Navy established the Underwater Explosions Research Division (UERD) in 1946 to find way to strengthen ships’ hulls. The film shows footage of ships earmarked for the scrapyard being torpedoed as part of the test process before explaining what happens to a vessel during an underwater explosion (mark 04:45). We watch as a highly compressed gas bubble pulsates before creating a series of water plumes above the water line. The bubble causes severe pressure on any nearby object with the shockwave damaging a ship, even lift it into the air and slamming it back into the water. The film shows high-speed cameras being fitted into test ships to film damage (mark 07:30) with the captured footage shown and the details later analyzed (mark 11:00). The information ultimately will be used for new design techniques. There is a look of the UERD’s Submarine Shock Simulation Vehicle to evaluate the strength of submarines (mark 12:00) with additional footage of tests conducted using the vehicle as well as other ship explosions (mark 15:57) and experiments using simulated underwater mines (mark 18:00).

We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment! See something interesting? Tell people what it is and what they can see by writing something for example: "01:00:12:00 -- President Roosevelt is seen meeting with Winston Churchill at the Quebec Conference."

A RUSSIAN GHOST SUBMARINE, ITS U.S. PURSUERS AND A NEW COLD WAR || WARTHOG 2017
Warthog Defense


Published on Nov 3, 2017
The Krasnodar, a Russian attack submarine, left the coast of Libya in late May, headed east across the Mediterranean, then slipped undersea, quiet as a mouse. Then, it fired a volley of cruise missiles into Syria.

In the days that followed, the diesel-electric sub was pursued by the aircraft carrier USS George H.W. Bush, its five accompanying warships, MH-60R Seahawk helicopters and P-8 Poseidon anti-sub jets flying out of Italy.

Search for Missing Argentine Submarine Races As Crew’s Oxygen Dwindles
By: Ben Werner
November 21, 2017 12:02 PM • Updated: November 21, 2017 12:24 PM



The Navy deployed unmanned underwater vehicles Tuesday in the search for the missing Argentine submarine as officials worry about the crew’s remaining oxygen.

Under the worst-case scenario, the ARA San Juan—missing since Wednesday – could be running out of oxygen if the sub hasn’t been able to surface, Argentine Navy officials said Tuesday, according to news reports.

The search is focused on an area off the coast of Argentina, which for the past few days has been hammered by rough weather, including reports of 20-foot seas. Tuesday’s forecast called for calmer conditions to assist the search.

“This phase of search and rescue is critical,” Argentine Armada spokesman Enrique Balbi said.
“This is why we are deploying all resources with high-tech sensors. We welcome the help we have received to find them.”

The U.S. Navy is providing four unmanned vehicles to search underwater for clues to missing sub’s location, according to a Navy statement. The recently established Unmanned Undersea Vehicle Squadron 1, based in Pearl Harbor, Hawaii, brought to Argentina one Bluefin-12D (Deep) unmanned undersea vehicle (UUV) and three Iver 580 UUVs.

The Bluefin-12D can conduct search operations at 3 knots and down to a depth of nearly 5,000 feet, for 30 hours, according to a Navy statement. This is a smaller version of the UUV used by the Navy in 2014 to search for missing Malaysia Airlines Flight 370, thought to have crashed into the Indian Ocean.

The Iver 580s can operate at a depth of 325 feet, traveling at 2.5 knots, for up to 14 hours, according to a Navy statement. These UUVs cans search wide areas of the ocean using side scan sonar, which creates images of large areas of the seafloor, according to a Navy statement.

Also assisting the search is a Navy P-8A Poseidon aircraft and a NASA P-3 research aircraft. If a rescue is to be attempted, the Navy’s specialized undersea rescue team, based in San Diego, is already staged in Argentina if asked to help.

They've picked up an underwater explosion in the area being searched. An area that just happens to be right on the continental shelf. Why, if you're in peace time and in a damaged sub heading for a repair bay, would you take a course away from land? And what are the odds you'd just happen to have a catastrophic failure at the single point of that cruise where the water is deepest?

Something smells.

Argentine Navy: Water Entered Missing Sub’s Snorkel

November 27, 2017 by Reuters


ARA San Juan seen at its home base of Naval Base Mar del Plata. Photo:

By Hugh Bronstein BUENOS AIRES, Nov 27 (Reuters) – Water entered the snorkel of the Argentine submarine ARA San Juan, causing its battery to short-circuit before it went missing on Nov. 15, a navy spokesman said on Monday as hope dwindled among some families of the 44-member crew.

The San Juan had only a seven-day oxygen supply when it lost contact, and a sudden noise was detected that the navy says could have been the implosion of the vessel. Ships with rescue equipment from countries including the United States and Russia were nonetheless rushing to join the search.

Before its disappearance, the submarine had been ordered back to its Mar del Plata base after it reported water had entered the vessel through its snorkel, causing a battery short circuit, navy spokesman Enrique Balbi told a news conference.

“They had to isolate the battery and continue to sail underwater toward Mar del Plata, using another battery,” Balbi said.

After contact with the San Juan was lost, the Vienna-based Comprehensive Nuclear Test-Ban Treaty Organization, an international body that runs a global network of listening posts designed to check for secret atomic blasts, detected a noise the navy said could have been the submarine’s implosion.

The search for the 65-meter (213-foot) diesel-electric submarine is concentrated in an area some 430 km (267 miles) off Argentina’s southern coast. The effort includes ships and planes manned by 4,000 personnel from 13 countries, including Brazil, Chile and Great Britain.

Among the crew’s family members, fissures started appearing on Monday between those who refuse to give up hope and those who say it is time to accept that their loved ones will not come back alive.

Some relatives have said they are focusing on the lack of physical evidence of an implosion and the possibility that the submarine might have risen close enough to the ocean surface to replenish its oxygen supply after it went missing.

But Itati Leguizamon said she believed her husband, crew member German Suarez, had died.

“There is no way they are alive,” she told reporters, her voice shaking and eyes welling with tears. “It is not that I want this. I love him. I adore him. He left his mother and sister behind, but there is no sense in being stubborn.

“The other families are attacking me for what I am saying,” she said, “but why have they not found it yet? Why don’t they tell us the truth?” (Additional reporting by Eliana Raszewski; Editing by Lisa Von Ahn)

SALVAGE OF A SUNKEN SUBMARINE U.S. NAVY TRAINING FILM 21174
PeriscopeFilm


Published on Jan 3, 2018
The short U.S. Navy training film Submarine Salvage shows the process Navy salvage crews use to retrieve sunken submarines. USS Hoist ARS-40 is shown in operation in the film. The submarine shown being salvaged appears to be a WWII boat; the techniques shown probably would not work with a modern submarine due to the size of these vessels.

The film begins with a submarine sinking and the rescue of the ship’s survivors. Rescuing survivors is the only goal immediately following the sinking of a submarine. Once all survivors are rescued, the Navy’s next objective is salvaging the ship (02:23). Specialized equipment is used by salvage forces (02:45); however, depending on the operation, different equipment and methods are required for a successful salvage operation. Regardless of the various factors, three basic principles or steps are consistent for salvaging submarines: prepare a salvage plan, rig for lift, and execute lift. The first, prepare a salvage plan, includes evaluating the environment, choosing an appropriate lifting method, and determining the required lifting force. Officers gather information they need to formulate their salvage plan, operating out of the shipyard where the sunken submarine was built (03:41), giving them access to the engineering plans and other details of the ship. The ocean bottom is taken into account as the ocean environment is examined. Depth plays a role as to what divers can accomplish, and weather is also a factor that must be considered. Planners must also know the state of submarine, which comes from interviews with survivors and communication records from the ship. Shipyard managers assist the planners in what needs to be done to make the sub airtight, if possible. A diver is then sent down (06:24) to survey the ship and gather on-the-spot information, most importantly whether the hull is partially buried or not. This allows for planners to determine the lifting method. The different lifting methods are: patch and pump (07:41), pontooning (08:30), self-lift, and lift ship (08:55). Patch and pump is the most common, but it requires the most diver time. Pontooning is the only practical way to lift in deep waters (up to max depths of 300 feet). Lift ship is usually only performed in shallow water. Depth and time requirements determine which method should be used. Lifting force (09:57) involves taking into account displacement and mud suction to calculate the lifting force required to raise the sub. The salvage ship moves out to prepare to raise the sub (11:06). The second step is to rig the sub for lift by placing wires under the hull. Sometimes tunneling is required to accomplish this. Divers can also set wires via lancing. A chain sling (13:38) is used to cradle the sub during lift. Prior to the lift, the sub is made to accommodate as much self-lift as possible. Divers prepare by rehearsing each step and conducting every test necessary on a sister ship (15:40) so they will know exactly what to look for and do. The third step is executing the lift (16:56), which can be done by raising with pontoons, by liftship (stern lift or bellylift), or by self-lift. Pontoons are moved into the water in preparation for lift (17:08). The submarine is gradually lifted over several stages of lifting to shallower depths. Lifting ships, such as YHLCs (19:16), the Navy’s heavy lift ships, can be used to pick up a sub. This must be done in pairs, and can lift via a bellylift or a stern lift. The submarine is lifted to the surface (28:06) during the salvage operation using a pontoon lift. Though the Navy’s increase in submarines comes with an increase in accidental sinking, well-planned salvage operations make it possible to retrieve sunken submarines and minimize Navy losses.

USS Hoist (ARS-40) was a Bolster-class rescue and salvage ship acquired by the United States Navy during World War II. Its task was to come to the aid of stricken vessels. Hoist was launched 31 March 1945 by the Basalt Rock Company shipyard near Napa, California; sponsored by Mrs. William E. Howard; and commissioned 21 July 1945, Lt. Cmdr. R. M. Brunner in command.

Amateur Built Submarine "Euronaut" - First Aid Training
Deep Blue Sea


Published on Jan 11, 2018
Despite every car driver and most of the recreational divers in Germany visited a first aid course at least once in their lives, drills are necessary to make life saving in case of an accident more efficient. But no of these courses teaches how to handle and to transport an unconscious person in a very cramped space such as a submarine with narrow passages and hatches. The crew of Euronaut has to figure best rescue methods first. That most probable scenario is a diving accident. Valuable information has been gathered during this training, that lead to the overworked safety concept and a new equipped rescue case.

Shot in August 2016

"Euronaut" is a private project of a research and diver support submarine around Carsten Standfuss - a German naval architect. It has been designed between 1988 and 2000. Then it took another 12 years to build it on holidays, weekends and after work. Most systems on board are second hand and homebuilt.

The sub has overall length of 16 m (52 ft), surface displacement of 57 tons and is capable of diving up to 250 m (820 ft).
Transit speed is up to 6 knots with a 190 hp diesel engine. Electric drive measures 40 kW.
The life support system provides air for the crew of six persons for a week. The diving chamber allows saturation dives to the depths similar to the operational depth of the submarine.

AMERICA'S NEW NUCLEAR MISSILE SUBMARINES MIGHT HAVE A PROBLEM || WARTHOG 2017
Warthog Defense


Published on Jan 11, 2018
The Government Accountability Office is raising concerns about the technological maturity of the Columbia-class ballistic missile submarine.

The new boomer, which must become operational by 2031, will feature a host of new technologies that are supposed to increase the vessels’ survivability into the foreseeable future. However, as the GAO notes, many of those features are unproven and no prototypes have been built or tested.

NEXT BIG SPENDING PROJECT for the US Military Columbia-class submarine the F-35 of the sea
ArmedForcesUpdate


Published on Jan 13, 2018
The Columbia-class submarine, formerly known as the Ohio Replacement Submarine and SSBN-X Future Follow-on Submarine, is a future United States Navy nuclear submarine class designed to replace the Trident missile-armed Ohio-class ballistic missile submarines.[3] The first submarine is scheduled to begin construction in 2021 and enter service in 2031 (some 50 years after its immediate predecessor, the Ohio class, entered service).[4][5] From there, the submarine class will serve through 2085.[6]

General characteristics[edit]

Graphic artist concept (2012)

Cutaway image
Although still evolving, the following are some of the ship characteristics for the SSBN(X) design:[4][25]

Expected 42-year service life (it is planned that each submarine will carry out 124 deterrent patrols during its service life)[26]
Life-of-the-ship nuclear fuel core that is sufficient to power the ship for its entire expected service life, unlike the Ohio-class submarines, which require a mid-life nuclear refueling[13]
Missile launch tubes that are the same size as those of the Ohio class, with a diameter of 87 inches (2,200 mm) and a length sufficient to accommodate a D-5 Trident II missile
Ship beam at least as great as the 42-foot (13 m) beam of the Ohio-class submarines
16 missile launch tubes[2] instead of 24 missile launch tubes on Ohio-class submarines. A recent report (as of November 2012) suggested that the boats will have 12 submarine-launched ballistic missile (SLBM) silos/tubes.[27] However, other sources do not support this.[28][29]
Although the SSBN(X) is to have fewer launch tubes than the Ohio-class submarine, SSBN(X) is expected to have a submerged displacement about the same as that of Ohio-class submarines
Also, the US Navy has stated that "owing to the unique demands of strategic relevance, [SSBN(X)s] must be fitted with the most up-to-date capabilities and stealth to ensure they are survivable throughout their full 40-year life span."[30]

In November 2012, the U.S. Naval Institute revealed, citing Naval Sea Systems Command, additional design information:[29]

X-shaped stern control surfaces (hydroplanes)

Electric drive
Off-the-shelf equipment developed for previous submarine designs (Virginia-class SSNs), including a pump-jet propulsor, anechoic coating and a Large Aperture Bow (LAB) sonar system.
The boats may also be equipped with a Submarine Warfare Federated Tactical System (SWFTS), a cluster of systems that integrate sonar, optical imaging, weapons control etc.[31][32][33]

Electric drive[edit]
Main article: Integrated electric propulsion
Electric drive is a propulsion system that uses an electric motor that turns the propeller of a ship/submarine. It is part of a wider (Integrated electric power) concept whose aim is to create an "all electric ship".[34][35] Electric drive should reduce the life cycle cost of submarines while at the same time reducing acoustic signature.[36][37]

Turbo-electric drive had been used on US capital ships (battleships and aircraft carriers) in the first half of the twentieth century.[38] Later on, two nuclear-powered submarines, USS Tullibee and USS Glenard P. Lipscomb, were equipped with turboelectric drive but experienced reliability issues during their service life and deemed underpowered and maintenance heavy.[39][40][41] Currently (as of 2013), only the French Navy uses turboelectric drive on its nuclear-powered Triomphant-class submarines.[42]

Conceptually, electric drive is only a segment of the propulsion system (it does not replace the nuclear reactor or the steam turbines). Instead it replaces reduction gearing (mechanical drive) used on earlier nuclear-powered submarines.[34] In 1998, the Defence Science Board envisaged a nuclear-powered submarine that would utilise an advanced electric drive eliminating the need for both reduction gearing (mechanical drive) as well as steam turbines.[43]

In 2014, Northrop Grumman was chosen as the prime designer and manufacturer of the turbine generator units.[44] Turbine generators convert mechanical energy from the steam turbines into electrical energy.[45] The electrical energy is then used for powering onboard systems as well as for propulsion via electric motor.[44][46]

Various electric motors are being or have been developed for both military and non-military vessels.[47] Those being considered for application on future U.S. Navy submarines include: permanent magnet motors (being developed by General Dynamics and Newport News Shipbuilding) and a high-temperature superconducting (HTS) synchronous motors (being developed by American Superconductors as well as General Atomics).[47][48][49]

More recent data shows that the US Navy appears to be focusing on permanent-magnet, radial-gap electric propulsion motors (e.g. Zumwalt-class destroyers use an advanced induction motor).[50] Permanent magnet motors are being tested on the Large Scale

IN 2003, A CHINESE SUBMARINE SANK MYSTERIOUSLY, HOW THE CREW DIED IS HORRIFYING || WARTHOG 2018
Warthog Defense


Published on Feb 17, 2018
On April 25, 2003 the crew of a Chinese fishing boat noticed a strange sight—a periscope drifting listlessly above the surface of the water. The fishermen notified the People's Liberation Army Navy (PLAN) which promptly dispatched two vessels to investigate.

At first the PLAN believed the contact to be an intruding submarine from South Korea or Japan. But when Chinese personnel finally recovered the apparent derelict they realized it was one of their own diesel-electric submarines, the Ming-class 361.

RUSSIA'S MONSTER OSCAR-CLASS NUCLEAR ATTACK SUBMARINES CAN KILL AIRCRAFT CARRIERS || WARTHOG 2018
Warthog Defense


Published on Mar 8, 2018
On August 12, 2000, an explosion, followed by a massive detonation equivalent to three to seven tons of TNT, occurred on board the Kursk while it was submerged participating in a naval exercise off of Severomorsk. Up to twenty-three of the ship’s 118-man crew managed to survive the initial blast in the ninth compartment of the vessel, but rescuers were tragically unable to intervene in time. An investigation concluded that hydrogen peroxide leaking from a poorly welded Type 65 torpedo was the likely source of the first blast, leading to a chain detonation of the other torpedoes. Another theory is that crew error due to lack of training caused the torpedo detonation.

NO ONE KNOWS WHY A US NAVY ATTACK SUB EXPLODED UNDERWATER IN 1968 || WARTHOG 2018
Warthog Defense


Published on Mar 13, 2018
In May 1968, a U.S. nuclear-powered attack submarine was sent on a secret mission to spy on the Soviet navy. Seven days later, with the families of the crew waiting dockside for the USS Scorpion to return from a three-month patrol, the U.S. Navy realized that the submarine was missing. Scorpion had been the victim of a mysterious accident, the nature of which is debated to this day.

Two U.S. Navy fast attack submarines surfaced from below the in the Arctic Circle during a multi-national training exercise currently taking place north of Alaska.

The two submarines, the Los Angeles-class USS Hartford (SSN 768) and Seawolf-class USS Connecticut (SSN 22), both surfaced in the Beaufort Sea on March 10 as part of the ICEX 2018, a biennial exercise held in the Arctic and meant train submarine crews in extreme cold-weather conditions. This year, both fast-attack submarines as well the UK Royal Navy submarine HMS Trenchant (S91).

With the arrival of the submarines, the units participating will set up a temporary ice camp on the moving ice floe approximately 150 miles off the coast of the northern slope of Alaska in international waters.

“From a military, geographic, and scientific perspective, the Arctic Ocean is truly unique, and remains one of the most challenging ocean environments on earth,” said Rear Admiral James Pitts, commander, Undersea Warfighting Development Center (UWDC).

According to Pitts, operating in the Arctic ice presents unique circumstances that can impact everything from communication and navigation to how submarines operate, especially due to the contoured, reflective ice canopy when submerged.

“We must constantly train together with our submarine units and partners to remain proficient in this hemisphere,” Pitts said. “Having both submarines on the surface is clear demonstration of our proficiency in the Arctic.”

In recent years, the Arctic has been increasingly used as a transit route for submarines. The most recent ICEX was conducted in 2016 with USS Hampton (SSN 767) and USS Hartford (SSN 768).

The first Arctic under-ice operations by submarines were done in 1947-49. On August 1, 1947, the diesel submarine USS Boarfish (SS-327), with Arctic Submarine Laboratory’s founder Dr. Waldo Lyon onboard serving as an Ice Pilot, conducted the first under-ice transit of an ice floe in the Chukchi Sea.

In 1958, the nuclear-powered USS NAUTILUS made the first crossing of the Arctic Ocean beneath the pack ice. The first Arctic surfacing was done by USS Skate (SSN 578) in March 1959. USS Sargo was the first submarine to conduct a winter Bering Strait transit in 1960.

HOW AMERICA PLAN TO TACKLE RUSSIAN AND CHINESE SUBMARINES WITH UNMANNED 'SEA HUNTER' CRAFT?
Defense Updates


Published on Mar 14, 2018
America’s Sea Hunter has taken a major step forward.
On January 30, the U.S Navy accepted the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) from DARPA, the Pentagon’s premier technology-innovation agency. The Sea Hunter, as the first ship of the ACTUV program is called, is an unmanned ship primarily designed to track quiet diesel-electric submarines for months with little or no human help.

I would never get on a ship that is supposed to sink.

A nuke submariner friend of mine told me: "A nuke sub tied up at a dock is noisier than a diesel underway."

ANALYSIS OF THE CAPABILITIES OF USS COLORADO
Defense Updates


Published on Mar 25, 2018
The United States Navy commissioned its news attack submarine, USS Colorado (SSN-788) into service. The powerful Block III Virginia-class attack submarine joins the fleet as US is slowly replacing the long-serving Los Angeles-class boats as the backbone of the Navy’s undersea force.

USS Colorado is the fifth Block III Virginia-class attack submarine and the Navy expects to take delivery of three additional boats of the sub type in the next several years. The Block III version of the Virginia-class incorporates a number of improvements both to reduce the cost of the vessels and to improve performance.

The commissioning is significant, as it comes at a time when great power rivalry between the United States, Russia and China continues to heat up.

In this video, Defense Updates ANALYZES THE CAPABILITIES OF USS COLORADO.
Lets get started.
