With ultrafast decoy targets launching from the biggest plane ever made.

The U.S.-based aerospace company Stratolaunch announced that the company has signed a research contract with the Missile Defense Agency (MDA), which is a part of the U.S. Department of Defense (DoD), on hypersonic flight test services.

The DoD has been focused on hypersonic missiles for a long time now, mainly because of the significant threats they present such as difficulties in detecting, tracking, and intercepting due to being able to reach high speeds with the ability to maneuver along a flight trajectory.

More than two years after the rocket’s last launch, SpaceX appears to have finally decided to give at least one of two surviving Falcon Heavy Block 5 cores a new lease on life as a Falcon 9 booster.

Known as B1052, the Falcon Heavy side core or booster debuted in April 2019 as part of the first flight of the rocket’s Block 5 variant, successfully launching Saudi Arabia’s large Arabsat 6A communications satellite to an almost 90,000 km (56,000 mi) transfer orbit. Following in the footsteps of the first Falcon Heavy, the first Block 5 vehicle repeated its predecessor’s iconic double-landing back at Cape Canaveral. Just 74 days later, both Falcon Heavy Block 5 side boosters B1052 and B1053 launched again, this time supporting the US military’s long-delayed STP-2 rideshare and qualification mission.

Circa 2013 😳!

What would you do with a 600km high structure? That would be hundreds of times higher than the highest ever built so far. I think it is feasible. Here I will suggest super-light, super-strong building materials that can substitute for steel and concrete that can be grown up from the base using feasibly high pressures.

I recently proposed a biomimetic technique for printing graphene filaments to make carbon fur (- in this case, for my fictional carbon-obsessed super-heroine Carbon Girl. I am using the Carbon Trio as a nice fun way to illustrate a lot of genuine carbon-related concepts for both civil and military uses, since they could make a good story at some point. Don’t be put off by the fictional setting, the actual concepts are intended to be entirely feasible. Real science makes a better foundation for good science fiction. Anyway, this is the article on how to make carbon filaments, self-organised into fur, and hence her fur coat:)

America’s newest air-dropped nuclear weapon variant has entered production. The U.S. Department of Energy’s National Nuclear Security Administration (NNSA) announced that on November 23, it had successfully completed the first production units of the B61-12 Life Extension Program (LEP), an updated version of the warhead used on weapons dropped from fighters and bombers. This paves the way to create an estimated 480 of the weapons, which will homogenize four existing variants of the bomb.

The B61-12 LEP helps modernize America’s nuclear weapons stockpile and sustain the Nation’s air-delivered nuclear deterrent capability. The nuclear security enterprise and the U.S. Air Force worked together to deliver the B61-12 FPU after more than nine years of design, development, qualification, and component production.

Deployed from U.S. Air Force and North Atlantic Treaty Organization (NATO) bases, the B61 nuclear gravity bomb has been in service for over 50 years. Since the first B61 entered services in 1968, many modifications have been made to improve the B61’s safety, security, and reliability. Currently, there are four B61 variants remain in the stockpile: the 3, 4, 7, and 11. The B61-12 will replace the B61-3, 4, and 7.

Launched in 2010, DARPA’s Living Foundries program aimed to enable adaptable, scalable, and on-demand production of critical, high-value molecules by programming the fundamental metabolic processes of biological systems to generate a vast number of complex molecules. These molecules were often prohibitively expensive, unable to be domestically sourced, and/or impossible to manufacture using traditional synthetic chemistry approaches. As a proof of concept, DARPA intended to produce 1,000 molecules and material precursors spanning a wide range of defense-relevant applications including industrial chemicals, fuels, coatings, and adhesives.

Divided into two parts – Advanced Tools and Capabilities for Generalizable Platforms (ATCG) and 1,000 Molecules – the Living Foundries program succeeded not only in meeting its programmatic goals of producing 1,000 molecules as a proof-of-concept, but pivoted in 2019 to expand program objectives to working with military mission partners to test molecules for military applications. The performer teams collectively have produced over 1,630 molecules and materials to-date, and more importantly, DARPA is transitioning a subset of these technologies to five military research teams from Army, Navy, and Air Force labs who partnered with the agency on testing and evaluation over the course of the program.

“Biologically-produced molecules offer orders-of-magnitude greater diversity in chemical functionality compared to traditional approaches, enabling scientists to produce new bioreachable molecules faster than ever before,” noted Dr. Anne Cheever, Living Foundries program manager. “Through Living Foundries, DARPA has transformed synthetic biomanufacturing into a predictable engineering practice supportive of a broad range of national security objectives.”

The disclosure is the strongest indication yet that the service is banking on autonomous weapon systems to give it an edge in the increasingly fierce military competition with China.

Beijing is making moves to challenge the dominance of the American military. Reports claim that China wants to establish its first permanent military presence on the Atlantic Ocean in Equatorial Guinea. Palki Sharma tells you more.
