Cargo Drones, Cargo Air Vehicles, or Heavy Lift Drones are the latest in unmanned aerial vehicle (UAV), or drone, technology. These pieces of equipment are being developed to transport cargo manually, remotely, and autonomously and may be used in civilian and military applications (Using cargo drones in last-mile delivery | Deloitte, 2018). Boasting impressive carrying power, cargo drones can lift anywhere from 2.26 to 2449.39 kilograms (Team, 2021). This carrying power establishes new possibilities for the delivery of packages without direct human involvement and may therefore be used to deliver lifesaving supplies to dangerous locations. The technology is also more environmentally friendly than traditional delivery services. Cargo drones are most commonly “electric or hybrid-electric vehicles with four or more rotors” (Using cargo drones in last-mile delivery | Deloitte, 2018). Some cargo drones can take off and land from a standing position, known as either an eVTOL (electric vertical take-off and landing) vehicle or VTOL (vertical take-off and landing) vehicle. VTOL makes cargo drones more versatile than cargo planes as they do not require a runway for operation. Many companies are in the process of developing proprietary cargo drone technology to improve upon traditional forms of delivery services.
Igor Sikorsky once famously said, «the helicopter is probably the most versatile instrument ever invented by man», a thought echoed by many field commanders and soldiers alike. Indeed, helicopters provide a degree of versatility unlike any other present asset: they can be rapidly deployed, navigate through almost every type of terrain and provide firepower and protection. They cover a vast range of operational tasks, including reconnaissance, troops insertion and extraction, intelligence gathering, patrolling, SAR missions, and MEDEVAC. And now the Defiant, the latest arrival from Sikorsky and Boeing, has chosen its engine.
