Introduction
The utilization of Unmanned Aerial Vehicles (UAVs) or Unmanned Aerial Systems (UAS), commonly referred to as drones, has transcended their military origins and has evolved into versatile commercial tools. Today, drones have diverse applications, including the delivery of small packages, conducting industrial site inspections, monitoring infrastructure, mapping, crop monitoring, emergency response, and security surveillance. Early generation UAVs have their roots in the United States military and date back to the 1800s. Currently, with extensive commercial applications of UAVs, it is indisputable that this technology will undergo further expansion for healthcare delivery in both military and civilian contexts. Our objective is to provide an overview of UAVs and UAS, emphasizing their military applications and prominent commercial uses with a focus on the UAVs healthcare delivery in challenging and remote environments.
Background
The word “drone” refers to UAVs, an aircraft that does not require an onboard pilot in order to operate. The use of UAVs for warfare is responsible for paving the way for the drone technologies we have today. Military units across the globe were among the first to recognize the benefits drones could provide to wartime strategies. Current military drones are often associated with sleek, advanced planes and quadcopters. However, the world’s militaries first developed drone technology as balloons, torpedoes, and aerial targets, and have used drones since the mid-19th century for intelligence, surveillance, reconnaissance, precision strikes, and electronic warfare. They’ve advanced from basic reconnaissance to sophisticated, sometimes autonomous weapons capable of identifying targets, relaying communications, and disrupting adversary networks.
Top Commercial UAV Uses
Even though military drones have been used for over 150 years, civilian drone ventures began in 2005 when the FAA issued its first certificate for use. Drones have proven invaluable in sectors like agriculture, industry, utilities, renewable energy, mining, drone deliveries, and ports, enhancing efficiency and reducing risks. See Table 1 for an overview of the primary commercial applications for drones, with a specific focus on the following sectors: government applications, public safety including law enforcement, firefighting, lifeguarding, inspections applications, and more.

UAVs and Healthcare Delivery in the Military and Civilian Sectors
UAVs are rapidly integrating into military healthcare to expedite medical supply delivery, facilitate casualty evacuation, and minimize personnel risk in combat zones. This technology addresses logistical challenges in austere environments, supporting critical functions like point-of-injury care and prolonged field care. See Table 2 for an overview of UAVs use in military healthcare delivery.

In addition to their military applications, civilian drones are transforming healthcare by expediting the delivery of vital supplies and medications to underserved and remote areas in the US and worldwide. For further insights into medical drone applications, refer to Figure 1. These advanced aerial lifelines bridge emergency care gaps, ensuring vital resources reach patients in need, regardless of location. Capable of navigating challenging terrains and traffic patterns, medical drones improve life-saving outcomes and reshape healthcare logistics, making rapid response and care more accessible.

The use of drones is fairly established during natural disaster recovery, and during search and rescue operations. This technology presents significant potential for healthcare delivery in other domains of wilderness medicine. Advancements in drone technology, as exemplified by Zipline, a pioneering company in drone delivery, enable the utilization of UAVs in developing countries. Zipline’s drones, known as Zips, have transformed logistics by facilitating rapid and efficient delivery of medical supplies, vaccines, and blood products, particularly in remote and inaccessible areas. Commencing in Rwanda and expanding across Africa to Ghana, Nigeria, and Côte d’Ivoire. Zipline’s mission underscores the transformative power of technology and innovation. See Table 3 for key areas that use of UAVs for civilian healthcare delivery.
