There are warnings that different technologies will render the ocean “transparent”, so even the stealthiest submarines could be spotted by an enemy force… China has already developed submarine-spotting lasers. CSIRO is working with a Chinese marine science institute that has separately developed satellite technology that can find submarines at depths of up to 500 meters. But others say submarines are just a base platform for a range of new and evolving technologies. The Australian Strategic Policy Institute’s outgoing head, Peter Jennings, said the nuclear-propelled submarines that Australia will get as part of the Aukus alliance have more space and energy for being “motherships” than conventional submarines.
“They’re significantly bigger and the reactors give you the energy not just for the propulsion but for everything else inside the boat,” he said. “You then have a huge amount of space for weapons, for vertical launch tubes for cruise missiles and for autonomous systems that can be stored on board. Not only is it a fighting unit but you might have half a dozen remote systems fanned out at quite a distance. They’ll be operating a long distance away from potential targets, potentially hundreds of kilometers. According to the taskforce set up under Aukus, the new submarines will have “superior characteristics of stealth, speed, manoeuvrability, survivability, and almost limitless endurance”, with better weapons, the ability to deploy drones and “a lower risk of detection”.

In 2018 the NATO alliance, joined by Sweden and Finland, held Trident Juncture, its largest exercise since the end of the cold war, in Norway. That involved the first deployment of an American aircraft-carrier in the Arctic Circle for three decades. Western warships have been frequent visitors since. On May 1, 2020 a “surface action group” of two American destroyers, a nuclear submarine, support ship and long-range maritime patrol aircraft, plus a British frigate, practised their submarine hunting skills in the Norwegian Sea.
Such drills are not unusual. But on May 4, 2020 some of those ships broke off and sailed further north into the Barents Sea, along with a third destroyer. Although American and British submarines routinely skulk around the area, to spy on Russian facilities and exercises covertly, surface ships have not done so in a generation. On May 7, 2020 Russia’s navy greeted the unwelcome visitors by announcing that it too would be conducting exercises in the Barents Sea—live-fire ones, in fact. On May 8, 2020… the NATO vessels departed.
It is a significant move. The deployment of destroyers which carry missile-defence systems and land-attack cruise missiles is especially assertive. After all, the area is the heart of Russian naval power, including the country’s submarine-based nuclear weapons. Russia’s Northern Fleet is based at Severomorsk on the Kola peninsula, to the east of Norway’s uppermost fringes.
Western navies are eager to show that covid-19 has not blunted their swords, at a time when America and France have each lost an aircraft-carrier to the virus. But their interest in the high north predates the pandemic. One purpose of the foray into the Barents Sea was “to assert freedom of navigation”, said America’s navy. Russia has been imposing rules on ships that wish to transit the Northern Sea Route (NSR), an Arctic passage between the Atlantic and Pacific that is becoming increasingly navigable as global warming melts ice-sheets . America scoffs at these demands, insisting that foreign warships have the right to pass innocently through territorial waters under the law of the sea. Although last week’s exercise did not enter the NSR, it may hint at a willingness to do so in the future.
On top of that, the Arctic is a growing factor in NATO defence policy. Russia has beefed up its Northern Fleet in recent years…Russian submarine activity is at its highest level since the cold war…Ten subs reportedly surged into the north Atlantic in October 2019 to test whether they could elude detection….Russia’s new subs are quiet and well-armed. As a result, NATO’s “acoustic edge”—its ability to detect subs at longer ranges than Russia—“has narrowed dramatically.”
Russia primarily uses its attack submarines to defend a “bastion”, the area in the Barents Sea and Sea of Okhotsk where its own nuclear-armed ballistic-missile submarines patrol. A separate Russian naval force known as the Main Directorate of Deep-Sea Research (GUGI, in its Russian acronym) might also target the thicket of cables that cross the Atlantic.
The challenge is a familiar one. For much of the cold war, NATO allies sought to bottle up the Soviet fleet in the Arctic by establishing a picket across the so-called GIUK gap, a transit route between Greenland, Iceland and Britain that was strung with undersea listening posts….The gap is now back in fashion and NATO is reinvesting in anti-submarine capabilities after decades of neglect. America has stepped up flights of P8 submarine hunting aircraft from Iceland, and Britain and Norway are establishing P8 squadrons of their own. The aim is to track and hold at risk Russian nuclear subs as early as possible, because even a single one in the Atlantic could cause problems across a large swathe of ocean.
But a defensive perimeter may not be enough. A new generation of Russian ship-based missiles could strike NATO ships or territory from far north of the GIUK gap, perhaps even from the safety of home ports. “This technological development represents a dramatically new and challenging threat to NATO forces…. Similar concerns led the Reagan administration to adopt a more offensive naval posture, sending forces above the gap and into the maritime bastion of the Soviet Union.

The report from the Energy Futures Initiative released on August 15, 2017 by former Energy Secretary Ernest Moniz calls for greater federal investment in the US huclear-power industry. The report calls for expanded government loan guarantees, tax incentives and research on nuclear technology.
Nuclear power makes up about 20 percent of U.S. electricity generation, but the industry has been struggling. Five nuclear plants, with a combined capacity of 5 gigawatts, have closed early since 2013, and an additional six plants are scheduled to shutter early over the next nine years. Of the two new nuclear plants under construction in the U.S., one was halted by Scana Corp. in July 2017 and backers of the other, Southern Co.’s Vogtle plant in Georgia, are seeking additional aid from the federal government.
Westinghouse Electric Co., the nuclear technology pioneer that is part of Toshiba Corp., went bankrupt in March, after it hit delays with its AP1000 reactors at each of those plants. After it declared bankruptcy, Westinghouse — whose technology is used in more than half the world’s nuclear power plants — said it shifted its focus from building reactors to helping dismantle them.
The U.S. needs companies and engineers that can both build and run nuclear enterprises…. The U.S. Navy’s reactors require supplies and qualified engineers, and American nuclear scientists fill vital national security roles, it said. Companies, such as BWX Technologies Inc. of Lynchburg, Virginia manufacture nuclear components for both the commercial nuclear industry and naval reactors. If the commercial business collapses, that may mean one less company able to process highly enriched uranium, according to the report.
“A shrinking commercial enterprise will have long term spillover effects on the Navy supply chain, including by lessened enthusiasm among American citizens to pursue nuclear technology careers,” according to the report.
In addition to extending a tax credit for new nuclear power and the Energy Department’s loan guarantee program, the report says the federal government could also direct the Federal Energy Regulatory Commission to “place a greater emphasis on the national security importance of nuclear power and its associated supply chain.”
