There were no means to detect submerged U-boats, and attacks on them were limited at first to efforts to damage their periscopes with hammers. Nevertheless, by 1904, all powers still defined the submarine as an experimental vessel and did not put it into operational use. By the outbreak of the Russo-Japanese War, all the large navies except the Germans had acquired submarines. The first submarine with a torpedo was Nordenfelt I built in 1884–1885, though it had been proposed earlier. In 1866, British engineer Robert Whitehead invented the first effective self-propelled torpedo, the eponymous Whitehead torpedo French and German inventions followed soon thereafter. Even so, various attempts to produce submarines had been made prior to this. The first attacks on a ship by an underwater vehicle are generally believed to have been during the American Revolutionary War, using what would now be called a naval mine but what was then referred to a torpedo. Torpedo carrying missiles, such as ASROC and Ikara, were another area of advancement. Dedicated attack submarines, purpose-built to track down and destroy other submarines, became a key component as well. The Magnetic Anomaly Detector (MAD), diesel exhaust sniffers, sonobuoys and other electronic warfare technologies also became a staple of ASW efforts. ![]() Increasingly capable fixed-wing maritime patrol aircraft were also widely used, capable of covering vast areas of ocean. Helicopters, capable of operating from almost any warship and equipped with ASW apparatus, became commonplace during the 1960s. The superpowers of the era constructed sizable submarine fleets, many of which were armed with nuclear weapons in response to the heightened threat posed by such vessels, various nations chose to expand their ASW capabilities. Intelligence efforts, such as Ultra, had also played a major role in curtailing the submarine threat and guiding ASW efforts towards greater success.ĭuring the postwar era, ASW continued to advance, as the arrival of nuclear submarines had rendered some traditional techniques less effective. Technologies such as the Naxos radar detector gained only a temporary reprieve until detection apparatus advanced yet again. Techniques such as the Wolfpack achieved initial success, but became increasingly costly as more capable ASW aircraft were introduced. After a lull in progress during the interwar period, the Second World War would see submarine warfare and ASW alike advance rapidly, particularly during the critical Battle of the Atlantic, during which Axis submarines sought to prevent Britain from effectively importing supplies. Accordingly, multiple nations embarked on research into devising more capable ASW methods, resulting in the introduction of practical depth charges and advances in sonar technology the adoption of the convoy system also proved to be a decisive tactic. During the First World War, submarines deployed by Imperial Germany proved themselves to be a capable threat to shipping, being capable of striking targets even out in the North Atlantic ocean. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances of unrestricted submarine warfare and the introduction of submarine-launched ballistic missiles, which greatly increased the lethality of submarines.Īt the beginning of the twentieth century, ASW techniques and submarines themselves were primitive. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. Sensors are therefore a key element of ASW. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Royal Navy officers on the bridge of a destroyer on convoy escort duties keep a sharp look out for enemy submarines during the Battle of the Atlantic, October 1941Īnti-submarine warfare ( ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. ![]() JSTOR ( February 2009) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed.įind sources: "Anti-submarine warfare" – news Please help improve this article by adding citations to reliable sources in this article.

We must explain to our kids that this isn’t a make believe imaginary world, it is part of the real world. Their IPO is expected to do tremendously well and they will continue to do the minimum they deem necessary to protect users, especially vulnerable children, from the predators they know are present on the platform.įirst, not only must parents educate themselves on every aspect of their child’s journey within the games they play and the online worlds they traverse, they also need to get engaged in the overall process. The train has left the station as far as Roblox goes. Yet, everyday our children are venturing into these very situations without protection online. Especially not one with no rules, chaperones, or people you trust. You’d never send your child to a party filled with strangers. Jordan Foster, a leading Cyber Expert at Family Zone says of Roblox, "With limited safety measures embedded within the game, children are open prey for predators to communicate with.Consider it similar to sending a child out into a real room filled with strangers, with no barriers in place to stop people being able to talk to whomever they like.”įrom that point of view you can see the dilemma that parents are faced with. What role will China have with our families and lives in the US? It’s up to the public There are also concerns on deal making and expansion plans that the company has made in China through a partnership with Songhua River Investment Limited, a Tencent subsidiary. How do we teach them to protect personal information and create a level of trust? So what can be done? How do we tell our kids not to chat with people they don't know and not accept private messages from anyone they don't know. The public is still not discussing how Roblox is planning to add voice chat technology that potentially could expose children to pedophiles. Though Roblox has a team of 1,700 people and some level of technology automation deployed to monitor content, they have obviously outgrown their ability to manage the bullying, harassment and abuse of children on the platform. It is now almost impossible to reach a real human customer support agent. ![]() Perhaps they deploy technology to sense the context of the conversation but it does not understand full intent to provide helpful solutions or escalate questions to human customer support agents. We are also seeing frustrations from ineffective customer service support that seem to be unable to cater to requests from parents on a variety of important concerns. Parents fearing that this has “‘opened up a realm of fear about grooming and pedophilia.’” Despite their best efforts parents in the UK have had their children exposed to images such as “two naked male cartoon characters, aroused.One stood beside a female character, also naked, and was thrusting back and forth, simulating sex” and children as young as seven have been asked if they wanted to have sex. For their part Roblox has stated that they are working “relentlessly to create a safe and civil community.” Doing so in part by introducing stringent text-filtering, audio scanning and image detection technologies. I received this similar sentiment from several parents. We parents need to take the time to educate ourselves on this new cyber life and be prepared to deal with their kids addictions online.” It seems to me that the kids who would be struggling with bullying otherwise will have a similar experience virtually. When reaching out to parents in my network I asked them specifically about their children using Roblox. On top of the effects of screen addiction is the negative effect of cyber-bullying within the platform between users. That’s 11.5 working days each month! Pair that with the 2017 study by Christian Montag, a professor of molecular physiology at Ulm University, that suggests heavy use of certain video games may cause brain changes linked to addictive behaviors and you can see the potential danger of such use to the children of America. That averages out to just a touch over 92 hours per month per user. Roblox experiences 3 billion total engagement hours each month from their aforementioned 32.6 million daily users. Through all this positivity and growth a dark side and bad actors have emerged. In a perfect world this is great for children, but we know this world is not perfect. We must ask, is Roblox a game at all or more of a transformational disruptive change for our children? It attempts to convey the perception of a world in which one of the things you can do is play games constantly with characteristics such as persistent friends and currency from any device anywhere in the physical world. “Bloxburg lets users enjoy a life experience where they build their own homes, go to work, spend time with friends and enjoy recreational activities." |
