The Northrop Grumman X-47B (also known as Salty Dog.)VIDEO

The Northrop Grumman X-47B (also known as Salty Dog) is a demonstration unmanned combat air vehicle(UCAV) designed for aircraft carrier-based operations. Developed by the American defense technology companyNorthrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and subsequently became part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refuelling

The X-47B first flew in 2011, and as of 2015, its two active demonstrators have undergone extensive flight and operational integration testing, having successfully performed a series of land- and carrier-based demonstrations.In August 2014, the US Navy announced that it had integrated the X-47B into carrier operations alongside manned aircraft and by May 2015 the aircraft's primary test program was declared complete Northrop Grumman intends to develop the prototype X-47B into a battlefield-ready aircraft, the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) system, which will enter service in the 2020s. The X-47B demonstrators themselves were intended to become museum exhibits after the completion of their flight testing, but the Navy later decided to maintain them in flying condition pending further development

The US military X-47B UAV will serve the US navy well and will be the worst nightmare for the Russian military. The Northrop Grumman X-47B is a demonstration unmanned combat air vehicle (UCAV) designed for carrier-based operations. 
The US Navy has successfully catapulted a prototype drone from an aircraft carrier on Tuesday, which is the first step in a program designed to begin fielding drones on all Navy carriers between 2017 and 2020.

The flight serves as a milestone for the future of drone aviation, and US Navy officers have celebrated the success of its launch. But the flight of the unmanned aircraft, which is the size of a fighter jet, is likely to become the subject of criticism from those who believe drone usage hurts the US image – especially since drones are behind many civilian deaths on foreign grounds. 

Critics have already condemned the Navy’s $1.4 billion drone prototype program, relaying their concerns over the development of weaponized systems in which humans will have even less control over when it comes to launching attacks.

Human Rights Watch has particularly protested the development of drones that carry weapons and are fully autonomous, like the X-47B unmanned aircraft that the Navy launched from the USS George H.W. Bush on Tuesday. This unmanned aircraft can reach an altitude of more than 40,000 feet and has a range of more than 2,100 nautical miles, the Associated Press reports.


This model is particularly valuable because it has the capability to take off and land on an aircraft carrier. Developing such drones would allow the US to launch strikes from anywhere in the world, regardless of whether or not a foreign country allows the US on its grounds. 

The drone is fully autonomous in flight, and relies on computer programs to direct it – unless an operator programs it to operate otherwise. Most drones currently employed by the military fully rely on operators to control it from a remote location. 

While the X-47B is only intended for testing purposes rather than operational use, the Navy will use it for research purposes to develop advanced unmanned aircraft for use in future conflicts. When it comes to using lethal force, the X-47B still requires human approval. But Human Rights Watch believes the prototype research will lead to the development of drones that conduct deadly attacks with no human intervention. 

Steve Goose, director of the arms division at Human Rights Watch, expressed some of his fears with AP. 

“For us, the question is where do you draw lines?” he said. “We’re saying you need to draw the line when you have a fully autonomous system that is weaponized. We’re saying you must have meaningful human control over key battlefield decisions of who lives and who dies. That should not be left up to the weapons system itself.”

But despite fears over the future of fully autonomous drones that can launch deadly attacks from aircraft carriers, the Navy is hailing the flight of its prototype as a success it has long sought. 

“US Navy history is made!” the Navy wrote from its official Twitter account. “Was airborne at A. More to come.”

The Navy plans to release videos and photographs of the event, which Read Adm. Mat Winter wrote marks “an inflection point in history on how we will integrate manned and unmanned aircraft on carrier flight decks in the future.”
