Artificial intelligence wasted a veteran fighter pilot in a bunch of simulated dogfights

Scientists have claimed that computers would replace humans in the cockpit for some time, but artificial intelligence simply hadn't reached the point where it could compete successfully against a human opponent.


But now, at least in simulators, it has. ALPHA, the AI, bested a retired Air Force fighter pilot repeatedly while running on a tiny, cheap Rasberry Pi computer that is often used to teach children coding basics.

Retired Air Force Col. Gene "Geno" Lee helped guide ALPHA's programming and flew against ALPHA in a series of air battles in a computer simulator, battles that he lost every time when flying against the mature version of ALPHA.

At first, ALPHA was being used as a tool to create better simulators for training pilots and testing tactics. ALPHA took control of "Red" fighters flying against a "Blue" force. Red typically held a numerical advantage while Blue typically had a technological advantage with longer range missiles, a larger payload, and an AWACS flying in support.

The AWACS is a radar system that gave Blue forces better situational awareness and targeting data.

In the initial matchups, ALPHA's Red team won more than it lost but took heavy losses. Then Lee and the programmers at Psibernetix, the company that created ALPHA, began making adjustments to its programming and ALPHA begin to win. Soon, it won every engagement.

So, Lee decided to take control of a Blue fighter personally to try and give the other team an advantage. He flew engagement after engagement against ALPHA.

ALPHA won every fight and, whenever Lee stayed in the air for a protracted period, Lee was shot down.

Lee told the researchers that ALPHA was "the most aggressive, responsive, dynamic and credible AI (he's) seen-to-date."

Lee later told UC Magazine reporter M.B. Reilly that, after flying missions against ALPHA, "I go home feeling washed out. I'm tired, drained and mentally exhausted. This may be artificial intelligence, but it represents a real challenge."

Now, ALPHA does have some advantages of its own. First, it utilizes a "Genetic Fuzzy Tree" system. GFT systems work closer to the way a human brain works than most computers. Rather than try to calculate every variable when computing a solution, it keeps track of key bits of data and forms generalities.

But it can form decisions based on those generalities 250 times faster than a human can blink. When controlling four aircraft, it can take in all available sensor data, create a new plan of action, and adjust each jet's controls to implement that plan every 6.5 milliseconds.

This allows ALPHA to constantly choreograph the jets' movements to cover one another. If one pair of Red planes are forced to evade and are in danger, ALPHA can direct a second pair to move into position on the attackers instantly.

Researchers believe that if ALPHA was split among two computers, one handling sensor data and the other computing actions, ALPHA could adjust its plans and adjust flight paths 1,100 times per second.

The success of ALPHA is impressive, but the system isn't exactly ready for combat. While ALPHA receives sensor data with "noise" incorporated, errors and missing data that would occur in a real fight, it hasn't flown in a situation where the signals between planes were jammed. This would make its coordination between planes more challenging.

In their paper in the Journal of Defense Management describing ALPHA's success, the creators note that ALPHA would make a great wingman for human pilots. So, human pilots would fly lead and command the mission while sending AI controlled jets into the knife fight against enemy jets. This would match plans the Air Force has for the future.

The full paper on ALPHA, which goes into much greater detail about how ALPHA was created, how it works, and what its limitations are, is available in the Journal of Defense Management.

History

5 times the Army Reserve made a difference in a century of war

From brutal trench warfare in World War I to fighting the Nazis and challenging Soviet Russia during the Berlin Airlift, Army Reserve forces have faced the perils of combat for more than 100 years.

The Army Reserve started as a medical force designed to fortify the Army's shortfall of combat doctors. In 1902, Secretary of War Elihu Root proposed the creation of a volunteer reserve to augment the regular Army and National Guard in wartime, and on April 23, 1908, the Medical Reserve Corps, with 160 medical professionals, was launched, with one simple mission: keep Soldiers alive.

How R. Lee Ermey's Hollywood break is an inspiration to us all

While there have been many outstanding actors and celebrities who have raised their right hand, there has never been a veteran who could finger point his way to the top of Hollywood stardom quite like the late great Gunnery Sergeant R. Lee Ermey.

4 critical components to the success of the first total penis transplant

The procedure was performed on an Afghanistan war veteran wounded by an IED

Doctors at the Johns Hopkins University School of Medicine in Maryland announced the first-ever successful total penis and scrotum transplant was performed on an Afghanistan veteran recently. The recipient was wounded in an IED attack that left him without sexual or urinary function but left his internal organs unharmed.

The procedure was performed on March 26th and the unidentified "sergeant" will have urinary function by the end of the week.

Marines used a 3D printed F-35 replacement part for the first time

Marines with Combat Logistic Battalion 31, 31st Marine Expeditionary Unit, are now capable of "additive manufacturing," also known as 3-D printing.

This innovative process uses 3-D printing software to break down a digital model into layers that can be reproduced by the printer. The printer then builds the model from the ground up, layer by layer, creating a tangible object.

The 'indomitable determination' of John Paul Jones lives on in the Navy

April is a great month to remember the namesake of one of our Pearl Harbor guided-missile destroyers, USS John Paul Jones, named for a founding hero of our Navy and proudly known by the crew and their families and friends as "JPJ."

On April 19, 1775, the Battles of Lexington and Concord lit the match of Revolution against British tyranny. At the time Great Britain had more than 250 warships with nearly half having 50 or more guns – cannons. Our tiny naval force consisted of a few ragtag privateers and some humble sailing vessels. Even before our nation began, the founders commissioned 13 frigates and recruited warfighters, including immigrants like John Paul Jones.

This is how the 'missing man formation' honors fallen pilots

The first time I witnessed a 'missing man formation' was at the funeral of my grandfather, who flew the B-25 Mitchell during World War II. After his service in the Army Air Corps, he became a commercial pilot for TWA and then ventured into private flight. He died in an airplane crash at the age of 74 and my family gathered with his aviation community at Santa Paula Airport for his memorial.

At the ceremony, we looked to the sky as a group of planes from the Condor Squadron flew overhead. One of the planes banked away, leaving an empty space in the formation.

The symbolism was not lost on me.

This Army vet started a supplement company dedicated to education

Before John Klipstein joined the Army, he smoked a pack a day and his PT test run time was roughly 23 minutes — which accounts for the time spent throwing up on the side of the track. The military turned that around. The newly-minted 13B found a love for fitness and pushing his body to the limit. After leaving the military, he developed a line of supplements to help others do the same — safely.

Taiwan is ready to push back against China's aggression

Tensions between the Peoples Republic of China and Taiwan have recently flared up as China held the largest show of naval force in its history in April 2018, and made new threats directed towards Taipei.

"We would like to reaffirm that we have strong determination, confidence and capability to destroy any type of 'Taiwan independence' scheme in order to safeguard the country's sovereignty and territorial integrity," Ma Xiaoguang, a spokeswoman for the State Council's Taiwan Affairs Office, recently said.
