US unveils its latest nuclear stealth bomber

America’s newest nuclear stealth bomber made its debut Friday after years of secret development, and as part of the Pentagon’s answer to rising concerns over a future conflict with China.

The B-21 Raider is the first new American bomber aircraft in more than 30 years. Almost every aspect of the program is classified, Associated Press reported.

As evening fell over the Air Force’s Plant 42 in Palmdale, California, the public got its first glimpse of the Raider in a tightly controlled ceremony. It started with a flyover of the three bombers still in service: the B-52 Stratofortress, the B-1 Lancer and the B-2 Spirit. Then the hangar doors slowly opened and the B-21 was towed partially out of the building.

“This isn’t just another airplane,” Defense Secretary Lloyd Austin said. “It’s the embodiment of America’s determination to defend the republic that we all love.”

The B-21 is part of the Pentagon’s efforts to modernize all three legs of its nuclear triad, which includes silo-launched nuclear ballistic missiles and submarine-launched warheads, as it shifts from the counterterrorism campaigns of recent decades to meet China’s rapid military modernization.

China is on track to have 1,500 nuclear weapons by 2035, and its gains in hypersonics, cyber warfare and space capabilities present “the most consequential and systemic challenge to U.S. national security and the free and open international system,” the Pentagon said this week in its annual China report.

“We needed a new bomber for the 21st Century that would allow us to take on much more complicated threats, like the threats that we fear we would one day face from China, Russia, ” said Deborah Lee James, the Air Force secretary when the Raider contract was announced in 2015.

While the Raider may resemble the B-2, once you get inside, the similarities stop, said Kathy Warden, chief executive of Northrop Grumman Corp., which is building the bomber.

“The way it operates internally is extremely advanced compared to the B-2, because the technology has evolved so much in terms of the computing capability that we can now embed in the software of the B-21,” Warden said.

Other changes include advanced materials used in coatings to make the bomber harder to detect, Austin said.

“Fifty years of advances in low-observable technology have gone into this aircraft,” Austin said. “Even the most sophisticated air defense systems will struggle to detect a B-21 in the sky.”

Other advances likely include new ways to control electronic emissions, so the bomber could spoof adversary radars and disguise itself as another object, and use of new propulsion technologies, several defense analysts said.

“It is incredibly low observability,” Warden said. “You’ll hear it, but you really won’t see it.”

Six Raiders are in production. The Air Force plans to build 100 that can deploy either nuclear weapons or conventional bombs, and can be used with or without a human crew. Both the Air Force and Northrop also point to the Raider’s relatively quick development: The bomber went from contract award to debut in seven years. Other new fighter and ship programs have taken decades.

The cost of the bombers is unknown. The Air Force previously put the price at an average cost of $550 million each in 2010 dollars – roughly $753 million today — but it’s unclear how much is actually being spent. The total will depend on how many bombers the Pentagon buys.

“We will soon fly this aircraft, test it, and then move it into production. And we will build the bomber force in numbers suited to the strategic environment ahead,” Austin said.

Ellsworth Air Force Base in South Dakota will house the bomber’s first training program and squadron, though the bombers are also expected to be stationed at bases in Texas and Missouri.

Apple loses top phonemaker spot to Samsung as iPhone shipments drop, IDC says

Apple’s (AAPL.O), opens new tab smartphone shipments dropped about 10% in the first quarter of 2024, hurt by intensifying competition by Android smartphone makers aiming for the top spot, data from research firm IDC showed on Sunday.

Global smartphone shipments increased 7.8% to 289.4 million units during January-March, with Samsung (005930.KS), opens new tab, at 20.8% market share, clinching the top phonemaker spot from Apple, Reuters reported.

The iPhone-maker’s steep sales decline comes after its strong performance in the December quarter when it overtook Samsung as the world’s No.1 phone maker. It’s back to the second spot, with 17.3% market share, as Chinese brands such as Huawei gain market share.

Xiaomi, one of China’s top smartphone makers, occupied the third position with a market share of 14.1% during the first quarter, read the report.

South Korea’s Samsung, which launched its latest flagship smartphone lineup – Galaxy S24 series – in the beginning of the year, shipped more than 60 million phones during the period.

Global sales of Galaxy S24 smartphones jumped 8%, compared to last year’s Galaxy S23 series during their first three weeks of availability, data provider Counterpoint previously said.

In the first quarter, Apple shipped 50.1 million iPhones, down from 55.4 million units it shipped same period last year, according to IDC.

Apple’s smartphone shipments in China shrank 2.1% in the final quarter of 2023 from a year earlier.

The drop underscores the challenges facing the U.S. firm in its third biggest market, as some Chinese companies and government agencies limit employees’ use of Apple devices, a measure that mirrors U.S. government restrictions on Chinese apps on security grounds.

The Cupertino, California-based company in June will hold its Worldwide Developers Conference (WWDC), where it will highlight updates to the software powering iPhones, iPads, and other Apple devices.

Investors are closely watching for updates on artificial intelligence development at Apple, which has so far spoken little about incorporating the AI technology into its devices. The company earlier this year lost the crown as the world’s most valuable company to Microsoft (MSFT.O), opens new tab, Reuters reported.

China launch of relay satellite Queqiao-2 for lunar probe mission successful

(Last Updated On: April 12, 2024)

China National Space Administration (CNSA) said on Friday its launch of a key signal relay satellite was a “complete success” and it would serve as the communication bridge for its future lunar probe missions for years to come, state media reported.

China launched the satellite Queqiao-2, which was named after a mythological bridge made of magpies, and two miniature satellites, Tiandu-1 and Tiandu-2, on March 20.

Queqiao-2 will be used as a communications bridge between the ground operations on earth and upcoming lunar probe missions on the far side of the moon until at least 2030.

The moon’s near side always faces earth. That means data transfers from the far side are impossible because there is no direct line of sight.

Queqiao-2 researcher and developer Xiong Liang described the satellite as “the main switch” of the whole fourth phase of lunar missions, according to state television CCTV.

“Only when the main switch is flipped on, all the communications can kick off,” Xiong said.

Queqiao-2 will orbit the moon and relay signals to and from the Chang’e-6 mission, which expected to be launched in May. The robotic Chang’e-6 probe will seek to retrieve samples from an ancient basin, acquiring lunar material from the moon’s hidden side for the first time.

Queqiao-2 will also be used as a relay platform for the Chang’e-7 lunar mission in 2026 and the Chang’e-8 mission in 2028.

The functions and performance of Queqiao-2 met mission requirements and it will be able to provide relay communication services for China’s lunar exploration projects and future lunar missions for China and other countries, said the CNSA, according to CCTV.

Queqiao-2 entered its targeted elliptical orbit on April 2 after a correction midway, near-moon braking and orbital manoeuvre around the moon, CNSA said.

The satellite has successfully communicated with Chang’e 4, which was the first spacecraft to perform a soft landing on the far side of the moon and is still carrying out its exploration mission. It also communicated with the Chang’e-6 probe while it is still on the ground earlier this month.

The successful launch of Queqiao-2 comes after the failed launch of another lunar spacecraft DRO-A/B satellites, which was intended to enter the moon’s distant retrograde orbit (DRO).

China has not released any information on whether or not the satellites can be retrieved.

Russian space officials on Tuesday aborted the test launch of a new heavy-lift rocket from its far-eastern launch pad.

The Angara-A5 rocket was scheduled to lift off from the Vostochny space launch facility at 0900 GMT Tuesday, but the launch was aborted two minutes before, AP reported.

Yuri Borisov, head of Roscosmos state space corporation, said the automatic safety system canceled the launch after registering a flaw in the oxidizer tank pressurization system.

He said the next launch attempt was set for Wednesday.

Tuesday’s launch was to be the fourth for the Angara-A5, a heavy-lift version of the new Angara family of rockets that has been developed to replace the Soviet-designed Proton rockets.
