How Taiwan’s tiny chips are quietly shaping US geopolitics
Posted by Gemechu Taye in categories: computing, military
Taiwan’s dominance of the semiconductor manufacturing market has made it a vital geopolitical interest for the US.
Taiwan dominates the world’s supply of computer chips — no wonder the US is worried.
One aspect of Nancy Pelosi’s trip to Taiwan that has been largely overlooked is her meeting with Mark Lui, chairman of the Taiwan Semiconductor Manufacturing Corporation (TSMC). Pelosi’s trip coincided with US efforts to convince TSMC — the world’s largest chip manufacturer, on which the US is heavily dependent — to establish a manufacturing base in the US and to stop making advanced chips for Chinese companies.

DARPA moving forward with development of nuclear powered spacecraft
Posted by Shubham Ghosh Roy in categories: military, nuclear energy, space travel
WASHINGTON – The Defense Advanced Research Projects Agency on May 4 issued a solicitation for proposals for the next phase of a demonstration of a nuclear powered spacecraft.
The project, called Demonstration Rocket for Agile Cislunar Operations (DRACO), started over a year ago when DARPA selected a preliminary design for a rocket engine reactor developed by General Atomics, and chose two conceptual spacecraft designs by Blue Origin and Lockheed Martin.
The next phases of the program will focus on the design, development, fabrication and assembly of a nuclear thermal rocket engine. DARPA will conduct a “full and open competition” so this opportunity is not limited to the companies that participated in the first phase, a spokesperson told SpaceNews. Proposals are due Aug. 5.

Stop Sarmat (Satan II), Hypersonics — All Missiles — the Details
Posted by Greg Allison in categories: drones, military, space travel
The technology, even the interceptor systems already exists; We just need to integrate them. See my survey of the existing interceptors and how we could use them in conjunction with space launch rockets, such as a derivative of the Ares I-X which has already flown! Listen as I explain how many of these various interceptors you can fly in massive drone swarms from Ares I style boosters and larger variants.
Awesome deals for long term food supplies for those long missions to deep space (or prepping in case your spaceship crashes: See the Special Deals at My Patriot Supply: www.PrepWithGreg.com.

UN chief warns world is one step from ‘nuclear annihilation’

And now, for old fashion Nuclear Doom.
Music in comments.
UNITED NATIONS (AP) — The United Nations chief warned Monday that “humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” citing the war in Ukraine, nuclear threats in Asia and the Middle East and many other factors.

Space Command moving to Alabama: 4 steps remain; what’s next?
Posted by Genevieve Klien in categories: military, space
The U.S. Space Command’s proposed move to Huntsville passed a big test July 13 when the Pentagon released a draft environmental assessment finding “no significant impacts on the human or natural environment” if the headquarters is built on the Redstone Arsenal site.
Although there remain four steps ahead of the move, Republican U.S. Sen. Tommy Tuberville of Alabama said the environmental assessment should be the last major hurdle for the plan to move the command from startup headquarters in Colorado to a permanent site. The move would bring 1,800 headquarters staff and their families to north Alabama.
“The Redstone Arsenal site is the (Department of the Air Force’s) Preferred Alternative for implementation of the Proposed Action,” the environmental assessment said. The proposed action is a permanent headquarters.

Breakthrough in faster-than-sound jet engines
Posted by Dan Breeden in categories: military, space travel
Almost 75 years ago, U.S. Air Force pilot Chuck Yeager became the first person to fly faster than the speed of sound. Engineers have been pushing the boundaries of ultrafast flight ever since, attaining speeds most of us can only imagine.
Today, military fighter jets like the F-15 routinely surpass Mach 2, which is shorthand for twice the speed of sound. That’s supersonic level. On a hypersonic flight—Mach 5 and beyond—an aircraft travels faster than 3,000 miles per hour. At that rate, you could make it from New York to Los Angeles on a lunch break.
The same propulsion technology that goes into rockets has made hypersonic speeds possible since the 1950s. But to make hypersonic flight more common and far less expensive than a rocket launch, engineers and scientists are working on advanced jet engine designs. These new concepts represent an enormous opportunity for commercial flight, space exploration and national defense: Hypersonic aircraft could serve as reusable launch vehicles for spacecraft, for example.

DARPA’S Hypersonic Air-breathing Weapon Concept achieves successful flight
Posted by Dan Breeden in categories: energy, military
DARPA, in partnership with the U.S. Air Force, completed a free flight test of its Hypersonic Air-breathing Weapon Concept (HAWC) last week. The missile, built by Raytheon Technologies, was released from an aircraft seconds before its Northrop Grumman scramjet (supersonic combustion ramjet) engine kicked on. The engine compressed incoming air mixed with its hydrocarbon fuel and began igniting that fast-moving airflow mixture, propelling the cruiser at a speed greater than Mach 5 (five times the speed of sound).
The HAWC vehicle operates best in oxygen-rich atmosphere, where speed and maneuverability make it difficult to detect in a timely way. It could strike targets much more quickly than subsonic missiles and has significant kinetic energy even without high explosives.
“The HAWC free flight test was a successful demonstration of the capabilities that will make hypersonic cruise missiles a highly effective tool for our warfighters,” said Andrew “Tippy” Knoedler, HAWC program manager in DARPA’s Tactical Technology Office. “This brings us one step closer to transitioning HAWC to a program of record that offers next generation capability to the U.S military.”
