Context

On September 3, 2022, Russian state-controlled news network RT published an article that quoted the Russian Defense Ministry claiming that the U.S. has developed a drone to spread infected insects. The article refers to a patent document, "No. 8967029," issued by the U.S. Patent and Trademark Office. This story is being shared on Twitter and Facebook, referencing a translated version of the article on Teller Report, which has been known to publish unverified news about the Russian invasion of Ukraine. The article, which quotes Lieutenant General Igor Kirillov, head of the Radiation, Chemical, and Biological Defense Forces of the Russian Armed Forces, states that the patent describes the aircraft as capable of allegedly destroying or disabling enemy troops without putting the lives of U.S. service members in danger.

In fact

The document referred to by RT does exist. Patent US8,967,029B1 can be found on the United States Patent and Trademark Office website and was granted for an invention known as the Toxic Mosquito Aerial Release System (TMARS). The patent was issued in March 2015 and can also be viewed on Google Patents for ease of reference.

However, the patent documents do not reveal any link to the U.S. government, military, or any other official entity, as suggested by the Russian official quoted by RT. The device's inventor is listed as S. Mill Calvert of Manassas, Virginia, and the applicant (and assignee to whom the patent was granted) is "TMARS Associates, Trustee for Toxic mosquito aerial release system CRT Trust."

According to the device's description, the drone would be equipped with a unit containing mosquitoes and food containing a toxin, including any agent that can be carried and injected through an insect bite. The unit is equipped with a mosquito outlet tube and is remotely controlled. The patent documents suggest the device does not fall foul of the United States' obligations under international law as it can fit within the exceptions under these conventions for calmatives and biological agents with prophylactic or protective uses.

The patent documents consequently claim that the device can also be used for immunization by using toxins that activate a person's immune system. However, the technical problem that the device is described as solving and the rest of the application appear to indicate that the focus of the invention is for offensive military purposes. Explaining the advantages that it would offer, the patent application states: "With an aerial system for releasing infected mosquitoes, large masses of people can be immunized, and enemy troops can now be destroyed or disabled without having to risk or endanger our own troops."

The application appears to recognize that the device cannot be used for lethal purposes under current international humanitarian law. It states, "If such a delivery system enabling legal non-lethal uses were available, it could later be adapted for military uses should legal restraints be altered or eliminated."

Currently, biological and chemical weapons are prohibited under international law, in particular under the Biological Weapons Convention (which came into force in 1972) and the Chemical Weapons Convention (which came into force in 1997). The U.S. has ratified both these conventions and is bound by them.

While this does not mean that the deployment of a biological/chemical weapon is impossible, there is no evidence available that the U.S. military has acquired, deployed, or used the TMARS device. While the Russian Defense Ministry has made claims about the development of the device in the past, it has not claimed that it has ever been deployed.

The verdict

There is no evidence that the U.S. government, military, or other official entity has developed a drone that can spread infects. While a private individual has invented a drone that can spread infected insects, and the U.S. Patent and Trademark Office issued a patent for the same to a private trust, there is no evidence available to indicate that it has been acquired or deployed by the U.S. government or military. Therefore, we have marked this claim as false.

A previous version of this article indicated that the Russian Defense Ministry claimed that the Pentagon had developed the device in question and that the Teller Report, rather than RT, was the source of the information. This has been amended to reflect the source of the claim more accurately, and additional changes to the references refuting the claim have also been made for accuracy.
