A Chinese aerospace manufacturer on the weekend released high-resolution images of what could be China’s second stealth fighter.
For months, Shenyang Aircraft Corp (SAC), one of China’s principal aerospace firms, has been rumored to be working on the prototype of a stealth aircraft known as the J-21 “Snowy Owl.” This first came to the attention of defense analysts after a video surfaced in late June showing an aircraft fuselage covered in camouflage tarp being transported on a highway from SAC to a People’s Liberation Army Air Force (PLAAF) test center at Xian-Yanliang Airbase in Shaanxi Province, Defense News reported at the time.
Although experts cautioned that the video and images in June could have been part of a disinformation campaign, the crisp images of the dark-gray prototype serial “001,” posted on China Defense Blog on Saturday, appeared to provide confirmation that rival Chengdu Aircraft Industry Corp, which unveiled its J-20 less than two years ago, was no longer the sole player in China’s efforts to develop stealth aircraft. To date, two J-20 models have emerged and it is believed that the aircraft, which has encountered various delays mainly due to China’s engine technology “bottleneck,” will not be deployed before 2017 to 2019.
So far, there has been no confirmation that the covered fuselage seen in June and the prototype that emerged at the weekend are the same aircraft.
Defense experts remain divided on whether the J-20 and J-21, which outwardly have a similar appearance, with two engines, two tails and radar-evading design, would serve similar functions. However, preliminary image comparisons indicate that the J-21 is smaller than the J-20.
Some military analysts say that the PLAAF has been seeking more than one type of stealth aircraft, including a strike fighter and another serving as an air superiority fighter.
There has also been speculation that the J-21, which is sometimes referred to as the J-31, could serve as a carrier-based stealth complement to the non-stealthy J-15 “Flying Shark,” or as an export model, known as the F-60, to compete against Lockheed Martin Corp’s F-35.
Writing in Wired yesterday, defense analyst David Axe said that the emergence of the new prototype did not immediately imply that both the J-20 and J-21 will go through the development, testing and full-scale production phases. The US Air Force stealth program, he wrote, gave rise to no less than four stealth fighter prototypes in the 1980s, of which only two — the F-22 and F-35 — were eventually adopted, following billions of dollars of investment.
It is not unusual for China to play one defense program against another as a means to increase competition and encourage innovation. Despite the huge costs involved, a now richer Chinese military could also be more inclined to fund two or more stealth programs if the aircraft are intended to serve different purposes.
PROVOCATIVE: Chinese Deputy Ambassador to the UN Sun Lei accused Japan of sending military vessels to deliberately provoke tensions in the Taiwan Strait China denounced remarks by Japan and the EU about the South China Sea at a UN Security Council meeting on Monday, and accused Tokyo of provocative behavior in the Taiwan Strait and planning military expansion. Ayano Kunimitsu, a Japanese vice foreign minister, told the Council meeting on maritime security that Tokyo was seriously concerned about the situation in the East China and South China seas, and reiterated Japan’s opposition to any attempt to change the “status quo” by force, and obstruction of freedom of navigation and overflight. Stavros Lambrinidis, head of the EU delegation to the UN, also highlighted South China Sea
SILENCING CRITICS: In addition to blocking Taiwan, China aimed to prevent rights activists from speaking out against authoritarian states, a Cabinet department said The Ministry of Foreign Affairs (MOFA) yesterday condemned transnational repression by Beijing after RightsCon, a major digital human rights conference scheduled to be held in Zambia this week, was abruptly canceled due to Chinese pressure over Taiwanese participation. This year’s RightsCon, the world’s largest conference discussing issues “at the intersection of human rights and technology,” was scheduled to take place from tomorrow to Friday in Lusaka, and expected to draw 2,600 in-person attendees from 150 countries, along with 1,100 online participants. However, organizers were forced to cancel the event due to behind-the-scenes pressure from China, the ministry said, expressing its “strongest condemnation”
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, said it expects its 2-nanometer (2nm) chip capacity to grow at a compound annual rate of 70 percent from this year to 2028. The projection comes as five fabs begin volume production of 2-nanometer chips this year — two in Hsinchu and three in Kaohsiung — TSMC senior vice president and deputy cochief operating officer Cliff Hou (侯永清) said at the company’s annual technology symposium in Silicon Valley, California, last week. Output in the first year of 2-nanometer production, which began in the fourth quarter of last year, is expected to
Taiwan’s economy grew far faster than expected in the first quarter, as booming demand for artificial intelligence (AI) applications drove a surge in exports, spilling over into investment and consumption, the Directorate-General of Budget, Accounting and Statistics (DGBAS) said yesterday. GDP growth was 13.69 percent year-on-year during the January-to-March period, beating the DGBAS’ February forecast by 2.23 percentage points and marking the most robust growth in nearly four decades, DGBAS senior official Chiang Hsin-yi (江心怡) told a news conference in Taipei. The result was powered by exports, which remain the backbone of Taiwan’s economy, Chiang said. Outbound shipments jumped 51.12 percent year-on-year to
