Large UAVs are what most people picture when talking about types of UAVs. They either require several people to carry them, or are launched by another method. But unlike small UAVs, they are typically too heavy to be launched manually by a single person. Like small UAVs, they often feature a fixed-wing or rotary wing style. They typically have a length or wingspan of five to 10 meters. They are capable of flying at altitudes less than 5,500 meters at speeds up to 125 meters per second. Medium UAVs are classified as being longer (or broader) than two meters. Because of their small size, most small UAVs are flown at altitudes near 125 meters at speeds less than 50 meters per second. They typically feature either a fixed-wing or rotary wing style. Small UAVs are slightly larger, spanning from just over 50 centimeters long to about two meters long. Their size also limits their altitude and speed, as they are usually flown at less than 125 meters high and speeds less than 50 meters per second. Size limits the ranges at which these UAVs can be detected by both radars and electro-optical / infrared (EO / IR) sensors. Because their natural design is so effective, many of the popular very small UAVs are modeled after insects with wings that either flap or rotate to keep them aloft. Their size and weight make them inconspicuous, so they are often used for reconnaissance and surveillance. Very small UAVs can range from just two centimeters long to about 50 centimeters long. Let’s take a deeper look at some of the features found in each size classification. For this reason, it’s also one of the main ways that UAVs are categorized.

Size is often a major factor for deciding which UAV is appropriate for a mission. Group (as classified by the Department of Defense).There are three main ways that UAVs can be categorized: Today we’ll take a look at UAV types and the different ways they can be categorized for better defense strategies. UAVs are the main part of unmanned aerial systems (UAS), which also include an operator or computer and a communication system that allows the two pieces to work together. They can be flown manually, but these days, many are flown by a remote operator, or even autonomously by onboard computers. UAVs, or unmanned / uncrewed aerial vehicles, are one of the biggest threats that warfighters face.
