Some initial tests on a compact power system which was designed to sustain a long-duration National Aeronautics and Space Administration (NASA) human mission on Mars have been successful.The tests were conducted in the US state of Nevada and a full-power run is scheduled for March according to the officials.
Sizeable details of the development of the nuclear fission system under NASA’s Kilopower project were shared by NASA and the US Department of Energy official at a LAS Vegas news conference. Continue reading

One use of the S-400 long-range missile is against stand-off systems including flying command posts and aircraft such as the E-3 Sentry AWACS. These aircraft, which are used by the US and its NATO allies with a squadron stationed in Japan at Kadena AFB and in the UAE at al-Dhafra, are vulnerable to S-400 interceptors and lose their stand-off range protection. We may be reaching the end of the AWACS capability, which were originally designed in the 1960s.
Saudi Arabia’s agreement to purchase the S-400 anti-aircraft Triumf anti-missile system from Russia is a major blow to the United States and its European allies. Continue reading

Close-in defense is becoming a very hot topic in American defense circles and in those of foreign powers as well. America’s land fighting forces are rushing to address their glaring short-range air defense (SHORAD) gap, while the US Navy is coping with the reality that enemies large and small could successfully take a swipe at one of their surface combatants using everything from small boat attacks, to small drone swarms, to anti-ship missiles, and especially in tight littoral environments.
Beyond the existing stalwart kinetic options, directed energy weapons have been seen as the holy grail of close-in naval defense, and it’s a space where the US Navy has spent significant development dollars in hopes of moving the technology forward. But lasers aren’t the only directed energy close-in weapon system (CIWS) solution—microwave systems may be an equally attractive and more attainable capability in the near term.
The Lockheed F-35 Lightning has been drawing a lot of press – and orders from across the world. According to a Lockheed website, 14 countries either have orders in or are looking at buying the Lightning. But another cheaper jet is making waves.
The Saab JAS 39 Gripen is part of a long line of Swedish jets, to include the Draken and Viggen. According to MilitaryFactory.com, the Gripen has a top speed of 1,370 miles per hour, and a maximum range of 1,988 miles. The plane is armed with a 27mm cannon and can carry a wide variety of air-to-air and air-to-surface ordnance. It is a very advanced fourth-generation fighter (arguably falling in the Generation 4.5 category with the Eurofighter Typhoon and the Dassault Rafale). Continue reading

First three sections of the Brazilian Navy’s lead Scorpene submarine, the S40 ‘Riachuelo’, were moved from the pre-outfitting site to the assembly site, ahead of the submarine’s launch in the second half of 2018. The move of three of overall five sections of the Riachuelo took place on January 13 and 14 and saw the 619-ton, 39.8-meter structure complete a five-kilometer journey in 11 hours.
Brazil’s four diesel-electric Scorpene submarines are built at a unique construction site at the Itaguaí Naval Complex comprising production and assembly facilities situated on two sides of the Bay of Sepetiba. The facilities are connected by a 4 km road that includes a 700-meter tunnel. Continue reading

The move comes as China looks to expand its military with the aim of having the best army in the world by 2030.The Long March 2D booster was sent into space from China’s Jiuquan Satellite Launch Center in the Gobi desert.
According to the dictatorship, the satellite is designed for remote-sensing of land resources, and the technology will analyse vegetation, water, impervious surfaces, nutrients, and soil.However, the launch comes just after two other space missions launched over the past few days. Continue reading

Whether America spends enough on defence depends on who you ask. A large section of its opinion makers are worried over “insufficient funding” for defence, and President Donald Trump has promised to make up for it. An alternative viewpoint with limited support from lawmakers is about how national wealth is being diverted to war preparations, at huge human cost.
But indisputable are the following facts. The U.S. accounts for 36% of the world’s total defence spending, nearly three times China’s share, which at 13% is the second biggest spender. In 2016, the U.S. spent $611 billion, which is more than the next eight spenders combined. China, Russia, Saudi Arabia, India, France, the U.K., Japan and Germany together spent $595 billion in 2016.

Boeing has unveiled a new unmanned electric vertical-takeoff-and-landing, or eVTOL, cargo air vehicle prototype that it plans to use to test and evolve future autonomous technology. “This flying cargo air vehicle represents another major step in our Boeing eVTOL strategy,” Boeing Chief Technology Officer Greg Hyslop said in a company press release “We have an opportunity to really change air travel and transport, and we’ll look back on this day as a major step in that journey.”
The eVTOL cargo air vehicle, announced on Wednesday, is designed to transport a payload up to 500 pounds, and will aid in future cargo and logistic applications, the company said. Continue reading
Modern warfare is waged largely on the electromagnetic spectrum. Although bombs and missiles get the headlines, they are just the kinetic step in a “kill chain” that relies heavily on electronic sensors and computers to detect, track, prioritize and target enemy assets. If the enemy is technologically advanced, it will be using its own array of electronic devices to deceive, disrupt or destroy attacking forces. These defensive measures will typically include methods for interfering with the electronic signals that smart bombs depend on for accuracy.
The struggle to control and exploit the electromagnetic spectrum makes today’s conflicts fundamentally different from those of the past. Although Sun Tzu understood 2000 years ago that success in war often depends on deception, the opportunities to confuse, disorient and demoralize adversaries have multiplied as the military enterprise came to depend so heavily on electronic tactics and tools. Electronic warfare thus is a central feature of military strategy for the foreseeable future. Continue reading
