UAS Missions and their Respective Attributes, Challenges, and Legalities

            There are many missions that unmanned aerospace systems (UASs) accomplish in both the public and civil realms. One of the most well suited missions to UAS is aerial Intelligence, Surveillance, and Reconnaissance (ISR). This mission set it not only a military mission, it is also conducted by police, border patrol, and FBI. All agencies that conduct aerial ISR via UAS share many of the same tactics techniques and procedures to accomplish the task. The type, size, and design of the UASs used in this mission vary widely based on where the mission is being conducted, the budget that a particular agency has for the mission, as well as other mission related constraints that are unique to each agency.     

            Three examples of platforms that accomplish the role of aerial ISR are the MQ-1C Gray Eagle which is used by the US Army, the MQ-8 Fire Scout which is used by the US Navy, and the Qube which was used by the Grand Forks, ND Police department to make its first night time arrest aided by a UAS (Koebler, 2014). The MQ-1C is a standard large fuel powered fixed wing UAS designed for launch and recovery via a 5,000ft runway. The Gray Eagle is capable of flying beyond line of sight as well as loitering for over 25 hours. This long loiter time and extended range provide the US Army with a powerful and capable system for aerial ISR (GA-ASI, 2016). 

The MQ-8 Fire Scout is used by the US Navy to conduct aerial ISR, but it is a rotary wing platform which aids in launch and recovery from ships and boats. The system is capable of flight up to 16,000ft as well as can loiter for over 12 hours. While not as capable as the Gray Eagle, the Fire Scout has the huge advantage of vertical takeoff and landing, which is vital when operating at sea (Northrup Grumman Inc., 2016). 

The Qube by AeroVironoment is a small battery powered quadcopter UAS that is utilized by the Grand Forks, ND police department to aid in criminal surveillance, which is the police version of ISR. The Qube is capable of only 40 minutes of flight and has a line of sight range of only 1km, but meets both the mission requirements and budgetary constraints of a small police department (AeroVironment Inc., 2016).

            The mission requirements vary depending on where and when the mission takes place, but there are some major considerations that must be taken in to account when selecting a UAS platform. Most aerial ISR systems need to be able to gain a vantage point that humans cannot typical achieve on foot. This means that they need to be well above the target. For high value targets in Afghanistan it could mean 20,000ft loiter altitude. For a ship or marine target, 10,000ft above the ocean may be the right solution. For a police chase in an urban area, a 400ft altitude could be adequate. The other main mission task that must be executed is relaying the video photography of the target back to the operator in near real time. Regardless of size, platform type, or cost, this function is accomplished at all levels for aerial ISR UASs.

            The major challenges for conducting aerial ISR can be two fold, there are platform based challenges as well as payload based challenges. In terms of platform challenges, achieving beyond line of sight flight is expensive and technologically advanced. The use of third party satellites is expensive as well as complex. Another aspect of flying beyond line of sight domestically is that is regulatory restrictive (Anderson, 2016). One Major benefit of utilizing UASs for aerial ISR is that they can remain in the air longer than most other manned platforms. Compared to systems like the MQ-12 Liberty manned airplane that is flown by the US Air Force, most UASs regardless of size can outlast it while conducting an ISR mission. The MQ-12 can only stay aloft for 6 hours without having to break station to refuel (Airforcetechnology.com, 2016). The MQ-1C can last a full 25 hours on one tank of fuel (GA-ASI, 2016).

            There are multiple legal and moral issues that often are challenging for UAS to be utilized in aerial ISR mission, and even more so when UASs are equipped with munitions such as the hellfire missile. In the case of a military UAS conducting ISR and firing hellfires there is a moral issue as to who is to blame in case of collateral damage cause by improper target identification, or lack of target area situational awareness (McGuire, 2015). There are major legal issues when conducting ISR domestically by the police. The main issue is privacy. Privacy is a huge concern for the American public, and when conducting police action, the use of a UAS could require a warrant depending the state. California is a very conservative state when it comes to UAS use by the police. Recently the state assembly approved a law requiring police to get a warrant to use a UAS to conduct a search (Bailey, 2014). Other states are working through litigation to determine the legality of UAS surveillance by police, but there are many challenges both perceived and actual to utilizing UASs for aerial ISR both domestically and deployed.
