This defense contractor wants to 'grow' drones in high-tech liquid ooze

A new initiative from BAE Defense Systems wants to create a system for "growing" drones in vats in a next-generation version of 3-D printing.


The process would be very quick, allowing military planners to manufacture new drones only weeks after a design is approved. That would allow custom aircraft to be grown for many major operations.

If the Air Force needed to get bombers past next-generation Russian air defenses, they could print drones specifically designed to trick or destroy the new sensors. If a group of troops was cut off in World War III's version of the Battle of the Bulge, the Army could resupply them with custom-designed drones carrying fuel, batteries, ammo, and more. Different designs could even be grown for each payload.

The drones would grow their own electronics and airframes, though key parts may need to be manufactured the old fashioned way and plugged into new drone designs. BAE's video shows a freshly grown aircraft receiving a final part, possibly a power source or sensor payload, on an assembly line after the craft leaves its vat and dries.

The 3-D printer that would be used, dubbed the "Chemputer" and trademarked by BAE, could potentially even recycle some of its waste and use environmentally friendly materials.

Since each aircraft is being custom built for specific missions or niche mission types, they can be highly specialized. One vat could print an aircraft optimized for speed that needs to outrun enemy missiles while the one next to it needs to act as a radio relay and has been optimized for loiter time.

The project is headed by University of Glasgow Regius Professor Lee Cronin. Cronin acknowledges that roadblocks exist to getting the Chemputer up and running, but thinks his team is ready to overcome them.

"This is a very exciting time in the development of chemistry," Cronin said. "We have been developing routes to digitize synthetic and materials chemistry and at some point in the future hope to assemble complex objects in a machine from the bottom up, or with minimal human assistance. Creating small aircraft would be very challenging but I'm confident that creative thinking and convergent digital technologies will eventually lead to the digital programming of complex chemical and material systems."

China and the US could end up in a war – here's what would happen

It's unlikely that the U.S.-China trade dispute is going to escalate to a full-scale war any time soon — but it's not impossible. Neither side is inclined to go to war with the other, but a war of that scale is what both plan to fight. All it would take is one bungled crisis, one itchy trigger finger, one malfunctioning automated defense system and the entire region could become a war zone.

This is how American pilots used drop tanks as bombs during WWII

If you pay attention, you might sometimes see long, cigar-shaped pods firmly attached to the undersides of classic fighter and attack aircraft, sometimes with unit markings on them.

Known as "drop tanks," these simple devices extend the range of the aircraft they're hooked up to by carrying extra usable fuel. Back during World War II, however, attack pilots found a secondary use for drop tanks as improvised bombs, used to bombard enemy ground positions.
