The Chinese Navy is already the largest in the world, with a fleet of more than 350 ships that includes a fast-growing armada of destroyers, carriers and submarines, a reality which continues to raise concerns with the Pentagon and Navy weapons developers. By the end of this decade, China is expected to operate as many as 400 ships, according to the Pentagon’s 2020 China Military Power report which catalogs the pace and extent of China’s ambitious military modernization. “China is the top ship-producing nation in the world by tonnage and is increasing its shipbuilding capacity and capability for all naval classes,” the report said.

My latest publication in Satellite Markets and Research, with significant contribution of Ms. Zoe Shahid.

Brisbane, Australia, September 4, 2020 —Exponentially increasing numbers of announced ambitious NGSO (Non-Geo Stationary Orbit) or LEO-HTS (Lower Earth Orbit – High Throughput Satellites) Mega Constellations have been creating waves in the world of technology. Their success will not be a mere disruption to the existing system, it will be a whole new system altogether.

With regular revisions in numbers of satellites from existing players and entrance of new players, these mega constellations will redefine the dynamics of Space Race 2.0, Industry 4.0, 4th, and 5th Dimension Warfare. With the rollout of a complete extra-terrestrial network there will be multiple challenges faced by the new ecosystem. With multiple revisions of filings with FCC (Federal Communication Commission) OneWeb (Qualcomm, Virgin, Airbus) leads the race with 48,000 satellites followed StarLink of SpaceX with 42,000 and Project Kuiper of Amazon with 3300 (1st numbers, may revise with the trend of the competitors) odd and other multiple constellations of smaller numbers. Recently, Huawei also announced its arrival with China Unicom with numbers of satellites not yet publicly announced. Security Challenges.

India has become the fourth country to successfully flight test hypersonic technology, joining an elite club alongside the US, Russia and China with the ability to develop missiles that can travel several times faster than the speed of sound.

Defence ministry says demonstration vehicle with scramjet engine reached an altitude of 30km and six times the speed of sound.

The DR7 is designed to be a personal commuter aircraft. So far, a 1/3 scale full composite proof-of-concept aircraft has been tested successfully. In order to minimize the propeller hazards, the rotors have been enclosed. They are tilted downwards for vertical take-off and landing (VTOL) launches and landings. They tilt horizontally to go forward. And all of this fits into a regular car garage.

Short of the revolutionary Burt Rotan wild aircraft designs, airplanes have changed little over the past decades. Winged-cylinder with a propulsion system is how we travel through the air. Unless you have the astronomical budget the military enjoys to design hypersonic aircraft, not for the general public, the choice is simple — airplanes or helicopters. DeLorean Aerospace just announced that its DR7 should fly by the end of 2018. That would shake things up, but is it practical, viable, for real?

DeLorean DR-7

In the 1980s, the DeLorean Motors Corporation gave us a break from the ho-hum cars sold everywhere by offering an aesthetically pleasing aerodynamic car. Eventually, DeLorean Aerospace picked up where its four-wheel parent left off, with a uniquely designed aircraft, the DR7. Although the name more or less gives it away, the company was founded in 2012 by Paul DeLorean, John DeLorean’s nephew. The mission was to develop a flying car.

Israeli VTOL air taxi developer Urban Aeronautics has announced it’s partnering with HyPoint to develop a long range, hydrogen-fuel-cell-powered, emissions-free version of its remarkable CityHawk aircraft, based on the military Cormorant/AirMule design.

HyPoint’s “turbo air-cooled” fuel cell design radically expands the power and lifespan of traditional designs, making it an ideal lightweight powertrain component for aviation use. Hydrogen is becoming one of the most exciting technologies in the emerging electric aviation market, with exceptional energy density compared to lithium batteries, as well as super-quick refueling as compared to long waits on a battery charger.

The CityHawk airframe looks like no other design in the eVTOL air taxi market. It has no wings or external propeller arms, and isn’t much bigger than a large SUV. Urban Aeronautics calls it a “fancraft,” after the large fans at the front and rear of the aircraft, totally shielded thanks to tiltable vanes at both the inlet and outlet sides, which can be moved to effect yaw and horizontal movements. For such a tiny ground footprint, it offers an impressive capability to seat six people.

Defense advanced research projects agency — DARPA.

DARPA and the U.S. Air Force (USAF) today announced successful completion of captive carry tests of two variants of the Hypersonic Air-breathing Weapon Concept (HAWC) and are ready to proceed to first free-flight testing within the calendar year. The joint Agency and Service effort seeks to develop and demonstrate critical technologies to enable an effective and affordable air-launched hypersonic cruise missile.

HAWC performers Lockheed Martin and Raytheon Technologies have each tested advanced air vehicle configurations that promise to achieve and sustain efficient hypersonic flight. Their upcoming flight tests will focus on hydrocarbon scramjet-powered propulsion and thermal management techniques to enable prolonged hypersonic cruise, in addition to affordable system designs and manufacturing approaches.

“Completing the captive carry series of tests demonstrates both HAWC designs are ready for free flight,” said Andrew “Tippy” Knoedler, HAWC program manager in DARPA’s Tactical Technology Office. “These tests provide us a large measure of confidence – already well informed by years of simulation and wind tunnel work – that gives us faith the unique design path we embarked on will provide unmatched capability to U.S. forces.”

In October 1961, the Soviet Union dropped the most powerful nuclear bomb in history over a remote island north of the Arctic Circle.

Though the bomb detonated nearly 2.5 miles (4 kilometers) above ground, the resulting shockwave stripped the island as bare and flat as a skating rink.

Onlookers saw the flash more than 600 miles (965 km) away, and felt its incredible heat within 160 miles (250 km) of Ground Zero. The bomb’s gargantuan mushroom cloud climbed to just below the edge of space.

Sarcos Robotics, a startup developing robots for industrial and defense applications, today nabbed $40 million in equity financing, bringing its total venture capital raised to nearly $100 million. The company plans to use the capital to commercialize its first full-body, self-powered product — the Guardian XO — ahead of an anticipated 2021 ship date.

According to a 2020 Grand View Research report, the exoskeleton market could be worth $4.2 billion by 2027. The firm sees adoption growing steeply in health care, where exoskeletons could address the increased prevalence of spinal cord injuries in industries like security, disaster recovery, infrastructure inspection and maintenance, maritime, oil and gas, and mining. The National SCI Statistical Center reported 17,730 new spinal cord injuries in 2019 in the U.S. alone.

Sarcos spun out from the University of Utah in 1983 and for years operated as a bioengineering research institution. By 2000, the lab had expanded into segments like animated film props, prostheses, and human-computer interfaces. A DARPA grant to develop a military exoskeleton steered Sarcos toward defense applications. After DARPA accepted Sarcos’ proposal in 2006, the company began developing prototypes and contracted with the U.S. Navy to pilot salvage robots.
