Japan, US move ahead in co-developing hypersonic weapons interceptor as regional threats grow

TOKYO: Japan and the United States on Wednesday signed an arrangement to jointly develop a new type of missile defense system as the allies seek to defend against the growing threat of hypersonic weapons, which are possessed by China and Russia and being tested by North Korea.
The project was initially agreed between Japan’s Prime Minister Fumio Kishida and US President Joe Biden at their summit last August and reaffirmed between the leaders during Kishida’s April visit to Washington. The Glide Phase Interceptor is planned for deployment by the mid-2030s.
Wednesday’s agreement determines the allocation of responsibility and decision-making process, a first major step in the project, Japanese defense ministry officials said. They hope to decide on Japanese contractors and start the development process by March 2025.
Hypersonic weapons are designed to exceed Mach 5, or five times the speed of sound, posing a threat to regional missile-defense systems with their speed and maneuverability. Developing interceptors of them is a challenge.

Japan’s defense ministry called it a “pressing issue” and noted that hypersonic weapons in the region have dramatically improved in recent years.
Under the arrangement, Japan is responsible for developing a part at the interceptor’s tip that separates in space to destroy the incoming warhead, as well as its rocket motors, officials said.
Japan has earmarked 75.7 billion yen ($490 million) for initial development and testing of the interceptor, according to the defense ministry.
The cost includes making components for the two companies, Raytheon Technologies and Northrop Grumman, that are developing the weapon in a competition led by the US Missile Defense Agency. One will be chosen for the project.
The MDA has estimated the cost to develop the hypersonic missile interceptor will exceed $3 billion, including Japan’s share of $1 billion.
The interceptors will be deployed on Aegis-class destroyers, like the ship-to-air Standard Missile-3 that Japan previously co-developed with the United States.
Japan has been accelerating its miliary buildup as it stresses the need to fortify its deterrence against growing threats. Japan has also significantly eased its weapons export policy to allow co-developed lethal weapons to third countries.

Tensions flare in Minnesota as protesters and federal agents repeatedly square off

  • The Trump administration has repeatedly defended the immigration agent who shot Good, saying he acted in self-defense
  • With the Department of Homeland Security pledging to send more than 2,000 immigration officers into Minnesota, the state, joined by Minneapolis and St. Paul, sued President Donald Trump’s administration Monday to halt or limit the surge

MINNEAPOLIS: Federal officers dropped tear gas and sprayed eye irritant at activists Tuesday during another day of confrontations in Minneapolis while students miles away walked out of a suburban school to protest the Trump administration’s bold immigration sweeps.
The government’s immigration crackdown is next headed to a federal court where Minnesota and two mayors are asking a judge to immediately suspend the operation. No hearing has been set on the request.
Gas clouds filled a Minneapolis street near where Renee Good was fatally shot in the head by an immigration agent last week. A man scrubbed his eyes with snow and screamed for help while agents in an unmarked Jeep sprayed an orange irritant and drove away.
It’s common for people to boo, taunt and blow orange whistles when they spot heavily armed agents passing through in unmarked vehicles or walking the streets, all part of a grassroots effort to warn the neighborhood and remind the government that they’re watching.
“Who doesn’t have a whistle?” a man with a bag of them yelled.
Brita Anderson, who lives nearby and came to support neighborhood friends, said she was “incensed” to see agents in tactical gear and gas masks, and wondered about their purpose.
“It felt like the only reason they’d come here is to harass people,” Anderson said.
Separately, a judge heard arguments and said she would rule by Thursday or Friday on a request to restrict the use of force, such as chemical irritants, on people who are observing and recording agents’ activities. Government attorneys argued that officers are acting within their authority and must protect themselves.
In Brooklyn Park, Minnesota, students protesting the immigration enforcement operation walked out of school, as students in other communities have done this week.
With the Department of Homeland Security pledging to send more than 2,000 immigration officers into Minnesota, the state, joined by Minneapolis and St. Paul, sued President Donald Trump’s administration Monday to halt or limit the surge.
The lawsuit says the Department of Homeland Security is violating the First Amendment and other constitutional protections by focusing on a progressive state that favors Democrats and welcomes immigrants.
“This is, in essence, a federal invasion of the Twin Cities in Minnesota, and it must stop,” state Attorney General Keith Ellison said.
Minneapolis Mayor Jacob Frey said: “What we are seeing is thousands — plural — thousands of federal agents coming into our city. And, yeah, they’re having a tremendous impact on day-to-day life.”
Dozens of protests or vigils have taken place across the US to honor Good since the 37-year-old mother of three was killed.
Homeland Security says it has made more than 2,000 arrests in the state since early December and is vowing to not back down. Spokesperson Tricia McLaughlin, responding to the lawsuit, accused Minnesota officials of ignoring public safety.
“President Trump’s job is to protect the American people and enforce the law — no matter who your mayor, governor, or state attorney general is,” McLaughlin said.
The Trump administration has repeatedly defended the immigration agent who shot Good, saying he acted in self-defense. But that explanation has been widely panned by Frey, Minnesota Gov. Tim Walz and others based on videos of the confrontation.
Two Democratic lawmakers from Massachusetts announced Tuesday they are sponsoring a bill to make it easier for people to sue and overcome immunity protections for federal officers who are accused of violating civil rights. The bill stands little chance of passage in the Republican-controlled Congress.
In Wisconsin, Lt. Gov. Sara Rodriguez is proposing that the state ban civil immigration enforcement around courthouses, hospitals, health clinics, schools, churches and other places. She is hoping to succeed Gov. Tony Evers, a fellow Democrat, who is not running for a third term.
“We can take a look at that, but I think banning things absolutely will ramp up the actions of our folks in Washington, D.C.,” Evers said, referring to the Trump administration. “They don’t tend to approach those things appropriately.”
