     India’s strategic Strike Nuclear Submarine INS Arihant carried out a successful launch of a Submarine Launched Ballistic Missile (SLBM) last Friday. The Indian Ministry of Defense (Mod) said that the test is important for the SSBN program. The program is a crucial element of India’s nuclear deterrence capability.
      A press release from the MoD said that “The missile was tested to a predetermined range and impacted the target area in the Bay of Bengal with very high accuracy. All operational and technological parameters of the weapon system have been validated. The successful user training launch of the SLBM by INS Arihant is significant to prove crew competency and validate the SSBN program, a key element of India’s nuclear deterrence capability. A robust, survivable and assured retaliatory capability is in keeping with India’s policy to have ‘Credible Minimum Deterrence’ that underpins its ‘No First Use’ commitment.”
     The INS Arihant was commissioned in 2016. The vessel is India’s first nuclear-powered ballistic missile capable submarine. The SSBN is a hull classification symbol for nuclear-powered ballistic missile carrying submarines. Operations of the SLBMs from the SSBN are under the control of Strategic Forces Command which is part of India’s Nuclear Command Authority. Officials said that the capability of being able to launch nuclear weapons from submarines has great strategic importance in the context of achieving a nuclear triad. This is especially true in light of the ‘no first use’ policy of India with respect to the use of nuclear weapons.
     The capability to launch nuclear missiles from submarines is in line with the target of creating a nuclear triad. Such a triad includes the ability to launch nuclear weapons from land, air and sea. The family of the indigenously developed Submarine Launched Ballistic Missiles is sometimes referred to as K-family missiles are codenamed after Dr. APJ Abdul Kalam. He was the central figure in India’s missile and space program. He also served as the eleventh President of India. Under the SLBM family, missiles of various ranges have been developed. The K-15 (also called the Sagarika) missile has a range of at least four hundred and seventy miles.
     India has also developed and tested the K-4 missiles from the same family which have a range of two thousand one hundred and seventy-five miles. India is working on more members of the K-family with higher ranges in the cards.
      The INS Arihant was commissioned in 2016 and launched in 2016. The next in the class, the INS Arighat was reportedly launched in 2017 and has been undergoing sea trials. In December 2021, the U.K.-based Janes Defense Weekly report that India had launched its third Arighat class submarines sometime in November of this year. 
     Before 2016, India already possessed land-based ballistic missiles and aircraft that are nuclear-capable. India’s land-based arsenal includes the Agni family of missiles with ranges from four hundred miles to eight thousand miles.
     India currently has four types of bombers that are capable of carrying nuclear bombs. Land and air strike capabilities are under the control of Strategic Forces Command which is a part of Nuclear Command Authority. Their inventory of aircraft includes the Mirage 2000H, SEPECAT Jaguar and Rafale, which were purchased from France.

     Seventy years ago, the British military conducted Australia’s first-ever nuclear weapons test on the Montebello Islands. Radiation is can still be detected on the Islands which occupy an archipelago of around 174 small islands (about 92 of which are named) lying 12 miles north of Barrow Island and 81 miles off the Pilbara coast of north-western Australia.  It is not clear if the islands are completely safe.
     Since 2019, an Edith Cowan University (ECU) study has been measuring exactly how much radioactivity still exists in the marine sediment on the islands. The team conducting the study has collected and tested more than 100 samples of marine sediments and marine life from the archipelago of islands.
        Madison Williams-Hoffman is a PhD student and is the lead researcher for the study. She said that researchers were still investigating the full extent of the radiation and the risk that it may pose.
     The scenic archipelago is among the most biodiverse marine environments in the world. It is a popular destination for tourists and fishers. Williams-Hoffman said that is was unrealistic to enact a blanket ban on visiting the area because the remote location of the islands would make it difficult to enforce.
     Williams-Hoffman hopes that the study will give people the power to make an informed decision as to whether they would be comfortable visiting the area. She said, “Even if you tell someone you can’t go there because [of] radiation risks, there’s always someone who’ll want to and you won’t entirely be able to stop them. But to give them the information so that they can make the decision for themselves, I think it’s a really important output from this project.” She added that the study’s first findings will be published next year.
      Jim Marlow is one of the many Australian servicemen who witnessed the test. They watched the historic moment from the deck of a small ship six miles away.  Marlow said, “We knew something was happening but there was little detail about it. We were just told to assemble on the deck, we were told to cover our heads and our eyes. It frightens the s**t out of you because you couldn’t say you expected it because you didn’t, you didn’t know it was coming. A loud bang followed by a rumble … and you see the smoke [and] sand starting to build up and it goes up and up and up and lines the sky.”
     Marlow is also part of the Australian Ex-Serviceman Survivors Association, and he has spent years lobbying for atomic veterans to receive recognition. He has said in interviews that he was worried that his exposure to radiation all those years ago could still pose a threat to his health. “In the case of the atomic veterans, the fallout from the detonation stays with you for a lifetime, so you don’t leave your war zone, it follows you everywhere you go. Fifty years later it’s still after you. I don’t know when it’s going to come and get me. I don’t know when it’s going to come to get my grandkids.”

     Alan Robock is a distinguished professor of climate science from Rutgers University’s Department of Environmental Sciences. He is also the co-author of the study in Nature Food. He claimed that World of Engineering’s estimate of two degrees Fahrenheit for two to three years was “wrong”. The effects on the climate would depend completely on the amount of smoke injected into the atmosphere. He added that the duration of the possible impact does not rely on the volume of smoke to address the question of how long they would last. For each scenario addressed, the maximum effects would last for five years.
     Robock said that the effects of increased ultraviolet (UV) light on crop varieties, people, and ecosystems are one aspect of atmospheric soot. The heating would destroy the ozone in the stratosphere. This would allow more UV radiation to reach the surface. However, the impacts would be felt instantly for even the tiniest amount of smoke. Before its effects could be felt at the surface of the Earth, the excess UV would be absorbed by the large amount of stratospheric smoke that has been accumulating for years.
      According to Robock, a nuclear war would result in lower temperatures because the soot would indeed rise high enough in the atmosphere to prevent rain from washing the soot out. The soot would then absorb sunlight which would result in turning the Earth’s surface dark and chilly. The idea that a small nuclear war would stop global warming is simply not true.
      Irrespective of whether the theory is accurate or not, it is worth noting that the World of Engineering Twitter thread warned of serious consequences of such an event. They could instead have chosen to suggest that the projected sharp decline in global temperatures would be highly beneficial to humanity.
      Even a small nuclear war would worsen the situation by sparking a brand-new climate crisis when considered in the larger context of climate change. As an example, significant crop disparities in major exporters like the U.S. and Russia would result in export restrictions. This would have an impact on the food supply for nations that rely heavily on imports.
      According to the study in Nature Food, a nuclear war between the U.S. and Russia could result in more than five billion deaths around the world. A war between Pakistan an India could result in more than two billion deaths worldwide. Other studies have also highlighted potential indirect effects of this kind of conflict. These could include significant oceanic damage, which would be likely to have further negative and less predictable effects on the environment.
     Although a small nuclear war might indeed have a temporary global cooling effect, it is not correct to state that this would end the climate crisis. This is in part due to the fact that while cooling effects would only last a short time, a nuclear winter would itself cause a climate crisis leading to a global food crisis and perhaps billions of fatalities.
