WASHINGTON — With bigger, faster missiles in development and bound for the fleet, the U.S. Navy's engineers are considering installing upgraded launchers on the stalwart Arleigh Burke-class destroyers.
The head of Naval Sea Systems Command, Vice Adm. Thomas Moore, told an audience at a conference of naval engineers that the Arleigh Burkes — due to their vertical launch system and Aegis missile capabilities — were easier to keep relevant than other destroyers such as the Adams and Spruance classes. Still, with the service attempting to keep the ships longer, new launchers may be in order to pace the threat from Russia and China, which have been developing their own hypersonic weapons.
“Vertical launch system has been a real game changer for us. We can shoot any number of things out of those launchers,” Moore said. “We'll probably change those out and upgrade them for prompt strike weapons down the road.”
Putting hypersonic weapons on surface ships would greatly increase the effectiveness of their strike capabilities. The current main strike weapon, the Tomahawk Land Attack Missile, is a subsonic missile that is vulnerable to evermore advanced Russian and Chinese air defenses.
Prompt strike, which refers to a Pentagon-wide effort to field hypersonic weapons to quickly strike anywhere in the world, are most likely coming first to submarines, said Thomas Callender, a retired submarine officer and analyst with the Heritage Foundation. Because subs are stealthy and can sneak in close to land undetected more easily than a surface ship, they make the most sense.
“They're looking at putting hypersonics on submarines first because where you can get access,” Callender said. “You can potentially then put them on surface ships as an added capability for them, but the submarines would be the priority for access and the ranges you can achieve.”
The Navy is designing a new large surface combatant to replace the cruisers and ultimately the destroyers with larger missiles in mind. As a result, the ship may be fairly large, former Surface Warfare Director Rear Adm. Ron Boxall told Defense News last year.
The benefit of larger vertical launch cells is that you can pack more missiles into each cell, if you are not using the cell for the larger hypersonic missiles, Boxall said.
“We are going to need, we expect, space for longer-range missiles,” he said. They are going to be bigger. So the idea that you could make a bigger cell, even if you don't use it for one big missile, you could use it for multiple missiles — quad-pack, eight-pack, whatever.”
The missiles that would go into a larger launcher are still very much under development.
The Navy is teamed with the Army to develop a booster for a hypersonic missile, and the Army is leading a team with the Navy and Air Force to internally build a common glide body that is producible on a larger scale.
Radar upgrades
Naval Sea Systems Command is also examining installation of a scaled-down version of the air and missile defense radar AN/SPY-6, under development for the Flight III DDG. The scope of that project, however, remains to be determined.
“We are looking at a scaled-back version of the air and missile defense radar to back-fit the Flight Is and Flight IIs, similar to how we are looking for a version of the [Enterprise Air Search Radar] developed for [the Ford-class aircraft carriers] to back-fit on some of the old Nimitz class,” Moore said.
“I'm not sure how many ships it is going to go on, we're still doing the design work. It's a fairly significant change to the structure of the ship, AMDR versus Spy.”
The purpose of the upgrade would be used to track the faster, more dynamic missiles under development by Russia and China.
The array is a smaller version of the SPY-6 intended for the Flight III DDG, the first of which is now under construction at Huntington Ingalls Industries. The SPY-6 destined for DDG-125 will have 37 radar modular assemblies, or RMA, which are 2-foot-by-2-foot-by-2-foot boxes that use gallium nitride technology to direct radar energy on air targets. The Flight IIA version will have 24 RMAs in the array.
A version of the radar planned for the FFG(X) future frigate is a nine-RMA configuration.
The Navy wants to upgrade all of its DDGs to Aegis Baseline 9 or higher with a ballistic missile defense capability and extend the service lives to 45 years as part of an effort to grow the fleet.
But the Navy is going to try to get 50 years out of its Flight IIA ships. The IIAs make up the bulk of the DDG fleet, with 46 total planned for the service — DDG-79 through DDG-124. DDG-127 will also be a Flight IIA.
That upgraded SPY-6 will be far easier to maintain than the current SPY-1D. Raytheon claims the radar can be maintained by simply removing an RMA and switching it out with a new one, with the rest of the work performed offsite.

As relations with Washington are expected to worsen at least until the U.S. presidential election later this year, Beijing has been making friendly overtures toward Tokyo and Seoul with an eye on economic revival after the pandemic passes, diplomatic sources said. Many foreign affairs experts are carefully watching what kind of foreign policy China will adopt at the postponed annual session of the country's parliament, the National People's Congress, scheduled to be convened next Friday. Recently, the administration of U.S. President Donald Trump has accused Beijing of failing to curb the spread of the virus, first detected late last year in the central Chinese city of Wuhan, and of not sharing relevant information in a timely manner. Trump has said the United States could even “cut off the whole relationship” with China, while threatening to impose tariffs as punishment for Beijing's alleged mishandling of the epidemic in the critical early months. Amid growing uncertainties over ties with the United States, “China is really eager to strengthen cooperation with Japan to revive the economy, which was hit hard by the virus outbreak,” a diplomatic source said. “For Japan, China is an essential trading partner. Japan also thinks the economy cannot rebound without cooperation with China. They are unlikely to be willing to ignite a controversy,” he added. In March, the Chinese Foreign Ministry abruptly announced a temporary ban on foreigners entering the country. The measure has applied even to those who hold a valid visa or residence permit. Beijing, however, has sounded out Tokyo on partially easing the restriction so that businesspeople who test negative for the new virus can travel between the countries, Japanese government sources said. China has already started to allow the entry of South Korean businesspeople meeting certain conditions in an attempt to ensure a smooth supply chain, which has been seriously disrupted in the wake of the virus spread. President Xi Jinping was quoted by the Chinese Foreign Ministry as telling South Korean President Moon Jae-in during a phone conversation on Wednesday that Beijing and Seoul “were the quickest to set up a joint response mechanism, and have maintained a track record of zero cross-border infections.” “The two sides also opened the first ‘fast-track lane' for urgently needed travels without compromising control efforts to facilitate the unimpeded operation of the industrial chain, supply chain and logistic chain in the region,” Xi told Moon. A source familiar with the situation in East Asia said, “For the time being, China's diplomacy may be determined by how much some countries can contribute to the economy. I'll be paying attention to what Foreign Minister Wang Yi says at the National People's Congress.” Tokyo has also taken a softer stand against China than other nations, as the governments of the world's second- and third-biggest economies have been trying to improve their ties by effectively shelving bilateral rows. Japanese Ambassador to Canada Yasuhisa Kawamura was quoted by China's Embassy in the country as telling Ambassador Cong Peiwu on May 8 that Tokyo is opposed to politicizing the pandemic and will work in tandem with Beijing to prevent infections. Earlier this month, the Japan Coast Guard said two China Coast Guard ships had approached and chased a Japanese fishing boat in Japanese territorial waters around the Senkaku Islands in the East China Sea. The group of uninhabited islets, called Diaoyu in China, are controlled by Tokyo but claimed by Beijing. Relations between the two countries have been often frayed by the territorial dispute, but strains did not escalate this time. Globally, more than 4.5 million cases of infection with the new virus have been confirmed, with the number of deaths exceeding 300,000, according to a tally by Johns Hopkins University. Meanwhile, China is facing some pressure over other countries regarding the virus outbreak, including Canberra that has asked for an independent investigation into the origins of the new coronavirus, prompting China to suspend beef imports from four major Australian meat processors, citing labeling and certification issues, in an apparent retaliatory move. “We will need an independent inquiry” to “learn the lessons,” Australian Prime Minister Scott Morrison told reporters on April 23. Australia is one of China's largest trading partners. “Now people are aware of my view about having the sort of authorities that would enable independent public health inspectors to be able to go into areas where a virus of potential pandemic implications can be understood quickly,” Morrison added. The Chinese Embassy in Canberra released a statement on April 28 saying Ambassador Cheng Jingye has “called on Australia to put aside ideological bias, stop political games and do more ... to promote the bilateral relations.” The Chinese Commerce Ministry has indicated that, following an 18-month investigation, it will impose anti-dumping tariffs on Australian barley. The punitive step would deal a stunning blow to Australia's agricultural sector. “If an independent inquiry is conducted, China may be blamed for the virus outbreak. China is worried that the proposal will be raised at the WHO's general assembly that will begin Monday,” a diplomatic source said, referring to the World Health Organization. China is also at odds with the United States, Europe, New Zealand and others over Taiwan's participation in the WHO as an observer. Beijing has long considered the self-governing, democratic island a renegade province awaiting reunification. The WHO has been criticized by the United States and some of its allies for having turned a blind eye when China allegedly withheld information that could have helped limit the epidemic. The global body's director general, Tedros Ghebreyesus, has strenuously rejected such accusations. Trump, who is believed to be attacking Beijing to gain public support ahead of the presidential election, has been one of the strongest critics of the WHO, calling it “a puppet for China.” In recent weeks he has frozen funding to the U.N. agency. Prime Minister Shinzo Abe has also said Japan, along with the European Union, will seek an investigation into the WHO's initial response to the coronavirus spread at the two-day annual meeting of its decision-making body in a virtual setting. https://www.japantimes.co.jp/news/2020/05/17/national/politics-diplomacy/china-japan-ties-us-coronavirus/#.Xs_4ijpKiUl
