Japan to acquire 20 unmanned helicopters

Yomiuri Shimbun reports the acquisition is designed to counter China’s growing presence.

The government plans to introduce about 20 large, unmanned helicopters to Maritime Self-Defense Force destroyers and other ships, several government sources said.

In response to China’s maritime expansion, the government wants to strengthen its early warning and surveillance activities around the Senkaku Islands in Okinawa Prefecture.

The helicopter model is expected to be selected in fiscal 2022, with the procurement starting in fiscal 2023, the sources said.

Early warning and surveillance activities in the East China Sea are currently conducted using MSDF vessels, surveillance helicopters, P-3C surveillance planes and other equipment.

With Chinese government ships regularly sailing around the Senkaku Islands and the Chinese military becoming more active in places such as the East China Sea and Pacific Ocean, figuring out how to operate with limited personnel and equipment has become an issue.

Ship-based unmanned aircraft can monitor faraway foreign vessels and other objects that cannot be captured by shipboard radar, which would expand the area over which a single MSDF vessel is able to cover in its surveillance.

Unmanned aircraft (See below) can also fly at night and in bad weather, giving them a broader range of operation than manned aircraft.

Learning from the disaster at the Fukushima No. 1 nuclear power plant of Tokyo Electric Power Company Holdings Inc., the government is considering equipping the drones with radiation sensors.

The Defense Ministry wants drones to take over duties that are risky for manned aircraft.

The unmanned helicopters would likely be deployed to Izumo- and Hyuga-class destroyers, as well as to a new destroyer with minesweeping capabilities.

The MQ-8C Fire Scout is considered the leading candidate. Made by Northrop Grumman Corp. of the United States, the 12.6-meter-long, 2.7-meter-wide unmanned helicopter can detect the movements of ships and other objects from an altitude of about 5,000 meters.

The U.S. Navy’s MQ-8B version is said to be capable of flying continuously for more than eight hours, or of operating for five hours over an area 200 kilometers from its base ship.

In December last year, the Cabinet decided to introduce three unmanned helicopters as part of the five-year Medium Term Defense Program for fiscal 2019 to 2023. The government wants to create a force of 20 such helicopters over the next decade or so.

Under the current legal framework, operating unmanned aircraft must be monitored by direct eyesight from manned aircraft or other locations. So the government will need to study and affect a change to the law to allow unmanned helicopters to operate independently.

This refers to planes and helicopters that can operate without onboard human pilots. They can be operated remotely or autonomously. The Self-Defense Forces are working on introducing three Global Hawks, which are unmanned reconnaissance planes that can monitor military movements from as high as 15,000 meters.

Hong Kong adds another dimension to US-China trade war

Hong Kong’s has become another consideration for Xi and Trump in their ongoing trade dispute. The United States and China have been embroiled in a trade war for almost two years with reciprocal tariffs and fiery rhetoric coming from both sides. Both economies have suffered and the world’s two largest economies both face the looming threat of recession. China, in addition to a tenuous economic situation is also facing more woes in Hong Kong, a Chinese territory that is self-governed. Protesters have taken to the streets in the island-territory after a proposed extradition law was publicly opposed. The protests have evolved beyond the initial grievances to long-held anxieties over the economy, living space and, ultimately, rule by Beijing. As the pro-democracy protests gather steam and threaten to become more widespread and violent, the United States has involved itself and ad

Why did Karachi sink in the rain?

The city’s topography has been altered without any regard to the overall form of the megapolis. As per the Meteorological Department’s near accurate prediction, Karachi experienced torrential rain this month. 27 people died and many more were injured. The situation was compounded by Eidul Azha that was being celebrated at the same time. Scores of cattle markets were set up in different locations across the city in addition to the central outlet along the Super Highway. Poor animals and their hapless keepers had to face a tough ordeal. Prices fell down sharply as animals began to fall sick due to the downpour and the filth. The rain caused a complete breakdown of urban life. Poor design and management of roads, drainage, intersections, underground sewers and sidewalks caused unparalleled chaos and

Moon urges Japan to choose ‘path of dialogue and cooperation’

Japan and South Korea have been locked in an increasingly ugly trade spat. President Moon Jae-in said Thursday that Seoul will cooperate with Tokyo if it retracts its recent trade restrictions, stressing the importance of international cooperation and free trade. “Within the realm of the international division of labor, if any country weaponizes a sector where it has a comparative advantage, the peaceful free trade order will inevitably suffer damages,” Moon said in his Liberation Day speech. “Better late than never. If Japan chooses the path of dialogue and cooperation, we will gladly join hands. We will strive with Japan to create an East

China, the United States and the story of agriculture

China says the US responsible for its farmers’ woes. Editor’s Note: Last week the Commerce Ministry said Chinese enterprises have halted the purchase of US agricultural products following Washington’s threat to impose 10 percent tariffs on another $300 billion of Chinese goods. Two experts share their views on the issue with China Daily’s Yao Yuxin. Excerpts follow: Declining exports to hit US farmers The Chinese enterprises’ decision to suspend the purchase of US agricultural products, mainly soybean, dairy products, sorghum and pork, will deal a fresh blow to farmers and traders in the United States. The escalating trade conflict between the world’s two largest economies has slashed US exports of farm produce to China, which used to be the largest importer of US soybean. China imported $9.1 billion worth of US farm produce last year, down fr
