Amberd (Armenian: Ամբերդ) is a 10th-century fortress located 2,300 meters (7,500 ft) above sea level, on the slopes of Mount Aragats at the confluence of the Arkashen and Amberd rivers in the province of Aragatsotn, Armenia. The name translates to “fortress in the clouds” in Armenian. It is also the name incorrectly attributed to Vahramashen Church, the 11th-century Armenian church near the castle. The village of Byurakan is 6.4 kilometres (4.0 mi) from the site of Amberd.

The site started as a Stone Age settlement. During the Bronze Age and Urartian periods, a fortress had been built that is now obsolete. Some sources say that Amberd used to be a summer residence for kings. The castle of Amberd and some sections of walls were constructed in the 7th century as a possession of the noble House of Kamsarakan.

Four centuries later the fortress and surrounding lands were purchased by the House of Pahlavuni and rebuilt by Prince Vahram Pahlavouni, as is recorded in the manuscripts of Grigor Magistros Pahlavuni. Vahram built the Church of Surb Astvatsatsin in 1026, fortified the complex with thicker stone walls, and added three bastions along the ridge of the Arkhashen canyon. Despite being unusual for a military installation, a bath house was built in the same period and has remained moderately intact along with the water supply system.

#Amberd was invaded in the 1070s by the Seljuq Turks who turned it into a military base. In 1197, a joint-army of Armenians and Georgians led by General Zakare Zakarian liberated the fortress. Under Zakarian control during the 12th and 13th centuries, the walls were structurally reinforced and the castle and outer buildings were renovated.

The noble Vacheh Vachutian purchased Amberd in 1215, making it a key defensive site in the region. Within a short period of time, the Mongols captured and destroyed the fortress in the year 1236. The site remained abandoned and untouched until the 20th century, when reconstruction and archaeological excavations began.

As weapons get more sophisticated, researchers are trying to build defence systems that can keep pace, and what’s better than a force field?

Aerospace and defence giant Boeing has been awarded a patent to develop a force field-like system that could protect military vehicles from shockwaves following explosions from missiles or improvised explosive devices.

Boeing’s proposed system involves using a combination of lasers, electricity and microwaves to rapidly heat up the air between the vehicle and a blast. This heat creates a plasma shield that’s denser than the surrounding air and able to deflect or absorb the energy from the incoming shockwave.

THE Call of Duty Black Ops 5 release date is expected to be announced in the coming months by Activision, but it doesn’t appear that it will be stealing the limelight from Modern Warfare.

The Hypersonic Conventional Strike Weapon (HCSW) program has been killed by the US Air Force as the service looks to make budget cuts in the area of hypersonic prototyping in the coming year.

Air Force spokeswoman Ann Stefanek revealed Monday that budget pressure, rather than performance, influenced the service’s decision to abandon its HCSW program and continue its development of the Air-Launched Rapid Response Weapon (ARRW) — its other hypersonic weapon program.

“We will continue to work collaboratively with our sister services to see how we can most effectively leverage each other’s capabilities, ensuring the most prudent use of taxpayer dollars,” she said in a statement emailed to Defense News on February 10.
