Unmanned Combat Aerial Vehicle Roles and Applications Explained

Unmanned combat aerial vehicles (UCAVs) have revolutionized modern warfare with their versatility and precision.

They can be used for surveillance and reconnaissance, providing real-time video feed to commanders on the ground.

UCAVs are also equipped with advanced sensors and communication systems, allowing them to transmit critical information to troops in the field.

Their ability to conduct precision strikes without putting human lives at risk has made them an invaluable asset in military operations.

The concept of the combat drone dates back to 1940, when Dr. Lee De Forest and U. A. Sanabria presented their idea in a Popular Mechanics article.

The modern military drone as we know it today was the brainchild of John Stuart Foster Jr., a nuclear physicist who drew inspiration from his model airplane hobby.

In 1971, Foster had the idea to apply model airplane technology to building weapons, and by 1973, Defense Advanced Research Projects Agency (DARPA) built two prototypes called "Praeire" and "Calere".

These early drones were powered by a modified lawn-mower engine and could stay aloft for two hours while carrying 28 pounds of load.

The first use of drones in war was during the 1973 Yom Kippur War, when Israel used unarmed U.S. Ryan Firebee target drones to spur Egypt into firing its entire arsenal of anti-aircraft missiles.

This mission was accomplished with no injuries to Israeli pilots, who soon exploited the depleted Egyptian defenses.

The Israel military pioneered the use of Unmanned Aerial Vehicles (UAVs) for real-time surveillance, electronic warfare, and decoys, which helped them neutralize the Syrian air defenses in Operation Mole Cricket 19 at the start of the 1982 Lebanon War.

This operation resulted in no pilots being downed.

The first armed drone was deployed by Iran in the late 1980s, during the Iran-Iraq War, and was armed with six RPG-7 rounds.

The US quickly acquired a number of UAVs, and its Hunter and Pioneer systems are direct derivatives of Israeli models.

The first 'UAV war' was the Gulf War, where at least one UAV was airborne at all times during Desert Storm, according to a May 1991 Department of the Navy report.

Since then, the US has increased its use of drone strikes in Pakistan as part of the War on Terrorism, with an estimated 2,400 people dying from U.S. drone strikes in five years.

Currently, several countries have developed dedicated armed UAVs, including the United States, China, Turkey, Pakistan, and Iran. These countries have also developed reconnaissance drones with armed capabilities, such as the CASC CH-92 and the IAI Eitan.

Some examples of current dedicated armed UAVs include the MQ-1 Predator, MQ-9 Reaper, and MQ-1C Gray Eagle from the United States, as well as the CAIG Wing Loong and Wing Loong-10 from China. These drones have been introduced into service since 1995 and have been used in various military operations.

Here is a list of some current dedicated armed UAVs:

Looking ahead, several countries are developing new technology demonstrators and projects, including the United States, the United Kingdom, China, and India. These projects aim to advance the capabilities of unmanned combat aerial vehicles and may lead to the development of new armed UAVs in the future.

The current state of dedicated armed UAVs is quite impressive. The United States has been a leader in this field, with the General Atomics MQ-1 Predator being introduced in 1995, followed by the MQ-9 Reaper in 2007 and the MQ-1C Gray Eagle in 2009.

Some countries are just starting to develop their own capabilities. For example, Australia has the Boeing MQ-28 Ghost Bat, which is expected to be introduced in 2024. This is a significant step forward for the country's military.

Here's a list of some current dedicated armed UAVs:

These are just a few examples of the many countries developing dedicated armed UAVs.

The future of unmanned aerial vehicles (UAVs) is exciting and rapidly evolving. Many countries are investing heavily in developing their own UAV technology demonstrators and projects.

The table below shows some of the notable technology demonstrators and projects in development around the world:

These technology demonstrators and projects are pushing the boundaries of what is possible with UAVs, and we can expect to see significant advancements in the coming years.

The first Unmanned Combat Aerial Vehicle (UCAV) played no part in the Vietnam conflict because it was still under development.

UCAVs are being developed by various countries, including France and the UK, which will continue to work on Future Combat Aircraft Systems with a focus on an Unmanned Combat Aerial Vehicle (UCAV).

The Indian Air Force (IAF) has an edge in search and strike capability thanks to its Heron, Searcher UAVs with Unmanned Combat Aerial Vehicle (UCAV) Harpy.

The Brazilian Air Force (FAB) is replacing its Lockheed C-130 Hercules with a more commercially capable aircraft, which is also being considered as a potential replacement for fighter jets in the future.

The study on UAVs looked at the impact on the mission space assuming Predator, Global Hawk, Unmanned Combat Aerial Vehicle (UCAV), and three other systems were procured with modular payloads.

Here are some examples of UAVs:

Advanced UAVs are getting smaller, with some weighing as little as 20 pounds. This allows them to be more easily transported and deployed.

Their increased maneuverability and precision make them ideal for reconnaissance and surveillance missions. They can fly at speeds of up to 400 mph and stay aloft for hours.

The introduction of advanced sensors and communication systems has greatly improved their effectiveness. These systems enable real-time data transmission and enhance their ability to detect and track targets.

The BAE Systems Taranis is a British unmanned combat air vehicle (UCAV) demonstrator program. It's part of the UK's Strategic Unmanned Air Vehicle (Experimental) program, and it's being developed as part of the £124m SUAVE program.

The Taranis demonstrator will have an MTOW of about 8000 kilograms, making it one of the world's largest UAVs. It's comparable in size to the BAE Hawk.

The Taranis is designed to be stealthy, fast, and capable of deploying a range of munitions over multiple targets. It can also defend itself against manned and unmanned enemy aircraft.

The first steel was cut in September 2007, and ground testing started in early 2009. The first flight took place in August 2013 in Woomera, Australia.

The demonstrator will have two internal weapons bays, allowing it to carry a variety of payloads. With its "full autonomy" feature, the Taranis will be able to think for itself for a large part of the mission.

The Miniature Aerial Munition System is a type of advanced UAV technology.

One notable example is the Lethal Miniature Aerial Munition System (LMAMS), which is a man-carried missile with many UAV characteristics such as loitering time. It also features a hand-held ground station.

These systems are designed for versatility and can be carried by an individual, making them ideal for specific missions that require a high degree of precision and stealth.

The EADS Surveyor is a fixed-wing, jet-powered UAV that's still in the preliminary investigation phase. It's being developed as a replacement for the CL-289 and will be a stealthy machine with a top speed of 850 km/h (530 mph).

The Surveyor will have an endurance of up to three hours and be capable of carrying a sophisticated sensor payload, including SIGINT gear. This makes it a powerful tool for military operations.

Here are some key features of the EADS Surveyor:

The Joint Unmanned Combat Air Systems (J-UCAS) project was a joint U.S. Navy/U.S. Air Force unmanned combat air vehicle procurement project.

J-UCAS was managed by the Defense Advanced Research Projects Agency (DARPA).

The program would have used stealth technologies and allowed UCAVs to be armed with precision-guided weapons.

Controllers could have used real-time data sources, including satellites, to plan for and respond to changes on and around the battlefield.

The J-UCAS program was later revitalized into UCAS-D, a United States Navy program designed to develop a carrier-based unmanned aircraft.

Here are the J-UCAS technology demonstrator aircraft:

The J-UCAS program was terminated in the 2006 Quadrennial Defense Review, but was later revitalized into the UCAS-D program.

The USAF Hunter-Killer program is a significant development in military technology. It involves the use of unmanned combat air vehicles (UCAVs) to conduct tactical strike missions.

The United States Air Force has shifted its focus from medium-range tactical strike aircraft to long-range strategic bombers. This shift is part of the Long Range Strike program.

For your interest: Micro Air Vehicles

Several UCAV designs are being explored for the USAF Hunter-Killer program. These include the Scaled Composites Model 395, Scaled Composites Model 396, General Atomics MQ-9 Reaper, and the Aurora Flight Sciences/Israel Aircraft Industries Eagle/Heron 2.

An unnamed Lockheed Martin entry is also being considered for the program.

Here's a list of the UCAV designs being explored for the USAF Hunter-Killer program:

Multinational efforts are underway to develop advanced UAVs. The EADS Surveyor is a prime example, a fixed-wing, jet-powered UAV designed to replace the CL-289.

It's positioned as a stealthy machine with impressive specs. The production Surveyor would have a top speed of 850 km/h (530 mph) and an endurance of up to three hours.

Let's take a closer look at some of its key features:

The EADS Surveyor is also notable for its development process. It's being developed from a demonstrator, the "Carapas", which is a modified Italian Mirach 100 drone.

Non-state actors have been increasingly using drones for malicious purposes. The Islamic State terrorist group began attaching explosives to commercially-available quadcopters, such as the Chinese-made DJI Phantom, to bomb military targets in Iraq and Syria.

In 2016-17, the Islamic State reportedly used drones as surveillance and weapons delivery platforms during the battle of Mosul. They used improvised cradles to drop grenades and other explosives.

Militant groups during the Syrian civil war have also used UAVs in attacks. A notable example is a swarm of drones armed with bombs attacking Russian bases in western Syria in early January 2018.

Mexican drug cartels started using drones in the 2020s, reportedly dropping hundreds of drone-carried bombs targeting both security forces and enemy gangs during turf wars.

Autonomous attacks raise complex questions about accountability and control.

Lethal autonomous robots may not be suitable for complex conflicts, as targeted populations would likely react angrily against them.

The public would be more outraged by machine failures than human error, making lethal autonomous robots politically implausible.

Giving weapon systems autonomous capabilities can lead to loss of control due to programming errors, unanticipated circumstances, malfunctions, or hacks.

Existing international humanitarian law is based on four principles: military necessity, distinction between military and civilian objects, prohibition of unnecessary suffering, and proportionality.

The attribution of moral responsibility under existing international humanitarian law is a topic of ongoing debate.

The use of unmanned combat aerial vehicles (UACVs) raises significant concerns about their effects on society and the individuals involved in their operation.

Drones can undermine the popular legitimacy of local governments, which are often blamed for permitting the strikes, leading to increased resentment among the population.

Some leaders worry that drone warfare can have a negative impact on soldiers' psychology, making war seem safer and easier, and potentially leading to a loss of deterrent.

However, this viewpoint is disputed by Mark Bowden, who argues that drone pilots are often shaken by the intimate and disturbing nature of their work, as they see their victims in their ordinary lives.

A sensor operator's account highlights the harsh reality of drone warfare, describing the gruesome aftermath of a strike and the emotional toll it takes on those involved.

The psychological effects of drone warfare are a growing concern. The extensive use of drones can lead to soldiers losing the deterrent that horrors of war provide, making them less effective in combat.

Keith Shurtleff, an army chaplain, worries that drone warfare can desensitize soldiers to the human cost of war. This is a valid concern, as soldiers are removed from the horrors of war and see the enemy as blips on a screen.

However, Mark Bowden disputes this viewpoint, saying that drone pilots often see the carnage close-up, in real time, and are sometimes shaken by what they witness. Drone pilots become familiar with their victims and see them in the ordinary rhythms of their lives.

One sensor operator's account illustrates the psychological impact of drone warfare: he watched a man take a long time to die after being hit, with blood squirting out of his leg. This kind of experience can have a lasting impact on a person's mental health.

The psychological effects of drone warfare are not just limited to soldiers. The public's perception of drone strikes can also be affected, leading to increased resentment against governments that permit them.

War Ethics can be a complex and sensitive topic, but it's essential to understand the key principles that guide military actions.

The principle of distinction, for example, states that military forces should distinguish between military targets and civilians, and only attack legitimate targets.

The principle of proportionality requires that the harm caused to civilians and civilian objects must be proportionate to the military advantage anticipated.

The Geneva Conventions and their Additional Protocols provide a framework for the protection of civilians and prisoners of war.

Targeting civilians is a war crime, punishable under international law.

The use of force must be proportionate to the threat posed by the enemy.

The principle of distinction is not always easy to apply, especially in situations where civilians are embedded with military forces.

The International Committee of the Red Cross (ICRC) plays a crucial role in promoting and protecting international humanitarian law.

War crimes, such as the use of chemical weapons, are considered particularly egregious offenses.

The ICRC's work in the field helps to raise awareness about the importance of respecting international humanitarian law.

The consequences of violating these principles can be severe, including prosecution and imprisonment.

The Israeli Air Force operates a squadron of Hermes 450s out of Palmachim Airbase south of Tel Aviv.

These Hermes 450s have been adapted for use as an assault UAV, reportedly equipped with two Hellfire missiles or Rafael-made missiles. The Israeli Air Force has used them extensively in the Gaza Strip and during the Second Lebanon War.

The Hermes 450 is a significant example of a UAV's versatility and adaptability. It's been modified for a specific mission, showcasing the potential of unmanned systems.

The Taranis, a British demonstrator programme, is another notable example of a UCAV. It's part of the UK's Strategic Unmanned Air Vehicle (Experimental) programme and has a Maximum Takeoff Weight of about 8000 kilograms.

This makes the Taranis one of the world's largest UAVs, comparable in size to the BAE Hawk. It's also stealthy, fast, and capable of deploying a range of munitions over multiple targets.

Countries with known operational armed drones include Azerbaijan, Botswana, Brazil, Colombia, China, Croatia, Cyprus, France, Germany, Georgia, India, Iran, Israel, Italy, Mexico, Netherlands, North Korea, Pakistan, Palestine, Russia, Singapore, Spain, Taiwan, Tunisia, Turkey, and the United Kingdom. The United States also uses armed drones, specifically the MQ-1 Predator and MQ-9 Reaper.

Some of these countries have introduced legislation to regulate the use of armed drones. For example, U.S. Senators introduced a bill to ban the sale, transfer, and export of large armed drones to countries outside of NATO due to concerns about civilian casualties.

Here's a list of countries with known operational armed drones:

Public opinion on drone strikes is a complex issue. A 2013 poll by Fairleigh Dickinson University found that 75% of registered voters approved of the U.S. military using drones to carry out attacks abroad.

The majority of Americans seem to support drone strikes, but with some caveats. A Huffington Post poll in 2013 showed that 56% of Americans support using drones to kill "high level terrorists".

However, public opinion outside of America is far more critical of drone strikes. A Pew Research study in 2012 found that 20 countries surveyed showed widespread international opposition to US drone killings.

Interestingly, support for drone strikes varies by demographic. A 2015 poll found that Republicans and men are more likely to support U.S. drone strikes, while Democrats, independents, women, young people, and minorities are less supportive.

The international opposition to drone strikes is stark. A 2014 report found that only three countries - the U.S., Kenya, and Israel - had at least half their population in favor of drone strikes.

Countries with known operational armed drones are diverse and widespread. Azerbaijan, for example, has a range of drones, including the IAI Heron, Elbit Hermes 900, and Elbit Hermes 450.

Some countries have a single type of drone, while others have multiple models. Colombia, for instance, has the Elbit Hermes 450.

France has a more complex drone system, with the EADS Harfang, SAGEM Sperwer, and MQ-9 Reaper. This highlights the varying levels of drone technology and capabilities among countries.

Countries with known operational armed drones include:

Drones are having unforeseen political effects, particularly in countries where they are used extensively. Some scholars argue that this will undermine the popular legitimacy of local governments, which are blamed for permitting the strikes.

U.S. Senators introduced a bill in 2020 to ban sales, transfers, and exports of large armed drones to countries outside of NATO due to concerns about civilian casualties.

The use of drones can increase resentment against local governments, as seen in Yemen where drone strikes have led to growing discontent. The Yemeni government is often blamed for permitting these strikes.

Soldiers' psychology is also a concern, as some worry that drone warfare can make war seem safer and easier, leading to a loss of deterrent. This is a similar concern that arose with the use of "smart" bombs in the First Gulf War.

Drone pilots can become familiar with their victims, seeing them in their ordinary lives, which can be intimate and disturbing. This is corroborated by a sensor operator's account of watching a man die after a drone strike.
