Google has confirmed that it is testing a drone delivery service dubbed as Project Wing, the Wall Street Journal reported.

Project Wing is the product of the division Google X, a department under Google that supervises the company's most secretive tech-based services.

In the testing procedures, Google X used an unmanned aerial drone to deliver various types of supplies to farmlands in Queensland, Australia. These include vaccines for animals, fresh water as well as dog food.

Rumors of Project Wing emerged after Google hired a new team leader for its division. Automotive engineer Dave Vos was chosen to take over the design process of the drone for Google X.

According to the company, the development of the drones could revolutionize how other corporations and organizations transport its good and other products. In addition to offering a faster alternative, drones are more energy efficient compared to other delivery methods, according to The Guardian.

"Self-flying vehicles could open up entirely new approaches to moving goods - including options that are cheaper, faster, less wasteful and more environmentally sensitive than what's possible today," the company said in a statement.

The confirmation of Project Wing comes approximately nine months after Amazon unveiled Prime Air, a drone delivery service which will be offered to consumers with premium preferences.

The firm explained that with Prime Air, Amazon could deliver its packages to consumers within 30 minutes or less, The Inquirer reported.

"We're excited to share Prime Air - something the team has been working on in our next generation R&D (research and development) lab," Amazon stated. "The goal of this delivery system is to get packages into customers' hands in 30 minutes or less using unmanned aerial vehicles."

However, the company clarified that it might take a few years before it offers the prime delivery service to its customers. Right now, Amazon is still in the process of perfecting the technology behind Prime Air and waiting on regulations from the Federal Aviation Administration (FAA).

"Putting Prime Air into commercial use will take some number of years as we advance technology and wait for the necessary FAA rules and regulations," the company said.
