The yanks sure are incompetent. This is a seawolf class submarine. The most advanced US sub. And it's sonar cannot detect the object?

Submarines don’t use active sonar; this would give their position away. They use passive sonar, which is just listening for the noises around it. You try walking through a room blindfolded, only by listening for the changes in ambient sound around you to detect objects. It is possible, but hard.

They should have a pin hole camera so the outside can b seen via video or digital cam...

20 years old liao. virginia class newer. but seawolf class is larger and carries more weapons. scs has a very hazardous acoustic environment and will pose problems for subs that rely on passive sonar, which the seawolf class primarily uses for object detection. usn may have to use active sonar but the pings will create “noise” where chicoms can pick up. a more advanced passive sonar tech may emerge as a result of this.

I thought the yanks have the most advance active passive sonar? Also there is some pinhole array shit ? Suppose to be the best

it might be hostile “object” at work. but the thick hy-100 steel hull will do damage to whatever hostile object that stood in its path.

You've been watching too many war movies. In real life, sonar is still not 100% reliable. There have been recent cases of submarines crashing into ships above them while attempting to surface.

A Japanese submarine collided with a commercial ship as it attempted to surface off the country's Pacific coast on Monday, government officials said.

Three crew members from the Maritime Self-Defense Force submarine Soryu suffered minor injuries, and pictures from the Japanese Coast Guard showed it sustained damage to its fairwater planes, the winglike structures on its conning tower.

The accident occurred off the main island of Shikoku in southern Japan.

The Soryu, commissioned in 2009, is the first in its class of Japanese diesel electric-powered submarines. It displaces about 3,000 tons and has a crew of around 65.
The Defense Ministry said communications equipment on the sub was also damaged, although it was still able to operate.

"Soryu scraped the hull of the vessel as it was surfacing. It is extremely regrettable the MSDF submarine has collided with a commercial ship," Defense Minister Nobuo Kishi said.

Could be a submerged shipping container too. There were thousands lost at sea in 2020, and more than 1000 lost as of April in 2021.

Malaysian submarine can dive already? The hatch fixed?

It's not chinese made and operated. Of course it can dive.
All those insults about the submarine cannot dive was by DAP. Offshoot of PAP.

Zahid: Our Submarine Can’t Dive​

By MT Webmaster On Feb 11, 2010

(AFP) – Malaysia’s first submarine, a European-made Scorpene delivered last September, has developed problems that make it unfit for diving, Defence Minister Ahmad Zahid Hamidi said today.

The KD Tunku Abdul Rahman sailed into a grand reception last year as the first of two commissioned from French contractor DCNS and Spain’s Navantia for a total of 3.4 billion ringgit.
Named after the country’s first prime minister, it was hailed as an important acquisition despite opposition allegations of corruption in the deal.
“The submarine can still dive but when we detected the defects, we were advised that it should not dive,” Zahid told reporters.

Do we need to worry about the US nuclear submarine incident in the South China Sea? Here's what experts say​

Defence experts say it is easy for submarines to bump into objects.( U.S. Navy: Timothy Aguirre )

A nuclear-powered submarine colliding with an unknown "object" under one of the world's busiest shipping lanes is rarely good news – but is the incident cause for concern?
Submarine incidents are usually shrouded in secrecy, given how critical these sophisticated (and expensive) pieces of equipment are in military operations.
We've talked to defence and security experts to help clarify what we know, what we don't know and what we may never know.

What could the unknown object possibly be?​

Vipin Narang, a professor of nuclear security and political science at MIT, says we shouldn't hold our breath when it comes to the USS Connecticut.
"It's totally unclear what hit it," he said.
When asked about the possibility of it hitting an enemy submarine, he said he doubts we will ever know.
"Not sure why we heard about this one — sometimes the damage is extensive enough that it's hard to hide," Dr Narang said.
But what have submarines collided with in the past, and can that give us any clues?

The submarine collided with an unknown "object" in the South China Sea.( US Indo-Pacific Command )
Peter Dean, Director of the University of Western Australia's Defence and Security Institute, told the ABC there were a few possibilities.
Euan Graham, a senior fellow for Asia-Pacific Security with the International Institute of Security Studies, largely agrees.
"They usually have good topographic knowledge of the areas they are patrolling, but there is always a risk of hitting a loose shipping container or other submerged object," he said.
The South China Sea, with its busy shipping lanes and fishing areas, is particularly risky for this, he added, especially when operating at shallow depth.
The number of shipping containers that fall off ships and sink to the bottom is astonishing, Professor Dean said.

How rare are underwater submarine collisions?​

The experts say such incidents are unusual but not unheard of.
There have been a number of such collisions in recent years, says Professor Dean.
In 2009, British submarine HMS Vanguard collided with French submarine Le Triomphant in the Atlantic Ocean while carrying nuclear missiles, in what the New York Times described as a "freak accident".
In 2005, BBC reported an American sailor died after his nuclear submarine – the USS San Francisco – ran aground near Guam.
Dr Graham said the fact that the USS Connecticut went to Guam suggests it suffered damage.
The US has said the submarine's nuclear propulsion system was unaffected by the collision and was fully operational.

How does monitoring equipment miss objects large enough to cause damage?​

Submarines use sonar rather than radar to detect objects around them when underwater.
But they don't use it constantly.

Experts say the South China Sea is noisy, so acoustic detection is challenging.( AP: Philippine Coast Guard/National Task Force-West Philippine Sea )
"They use sonar in passive mode or listening mode, they have sensors all around the sub, and an acoustic tail with sensors all over it. They do have active sonar that send out pings, which gives away your position, so they tend not to use that. Sometimes even with the best equipment, it's very hard to hear things," Professor Dean said.
Dr Graham said the South China Sea in particular was not conducive to listening.

What is the worst-case scenario?​

The USS Connecticut is a nuclear-powered submarine with a nuclear reactor on board and the risk of explosion is "a worry", said Professor Dean.
"We saw the Indonesian submarine that sank not long ago, we don't know the cause of that because no-one survived. In the 2000s, the Russians lost a nuclear submarine in the Barents Sea which triggered an explosion," he said.

Any significance of this incident occurring in the South China Sea?​

China has stepped up incursions into Taiwan's air defence identification zone.( AP: Taiwan Ministry of Defence )
The submarine collision has come at a time of heightened tensions in the Asia Pacific, with China and US relations worsening, and tensions between China and Taiwan heating up.
China has significantly increased the number of warplanes it sends into Taiwan's Air Defence Identification Zone, in moves considered provocative by both Taiwan and the US.
But the South China Sea, as mentioned earlier, is home to one of the world's busiest shipping lanes, and is also now a geopolitical hotspot as China and the US vie for primacy.
Professor Dean said it was "very, very unsurprising" for this incident to occur in that region.

How does a submarine with sophisticated sonar, radar and all those modern gadgets hit anything? And an unidentified object at that! Don't tell me US subs are useless.

Bhai,

Submarine navigation requires very detailed knowledge of the immediate surrounding area. There are two common methods of achieving safe, submerged navigation: Detailed charts and active high-frequency sonar employment.
Highly accurate charts are always the first choice. Active sonar transmissions are used to confirm the water depth checks with the chart. These active sonar pulses can be transmitted in front and to the sides of modern submarines. These short-range, high-frequency sonar systems reveal nearby underwater objects with great clarity. Submerged objects, such as mines, wrecks, and other submarines are plainly visible to a trained sonar operator.
The downside to the use of active sonar is that it is detectable and at approximately two times the range it allows the operator to search, in most ocean environments. A typical high-frequency, high-resolution sonar may see out to 5,000 yards and is vulnerable to detection out to least 10,000 yards or farther in good conditions. This means an adversary can localize a submarine’s position, and it can remain undetected while trailing the active-sonar emitting submarine for as long as it uses its high-resolution sonar.
