Predator launching a Hellfire missile
High operational reliability is an essential prerequisite for UAVs. A good engine is the most difficult aspect in the designing of a UAV. Designers have to make sure that the engine can support the airframe and the UAV has a low signature through low vibration. It should be able to support long-endurance missions over the target. Another area of operational reliability for a UAV comes from its airframe, which should be able to support the mission in all types of conditions, especially rough weather. There is a flipside to the development of the drones globally. A recent report by the Rand Corporation warned that, in the future, terrorist groups might be able to buy small, armed drones, “Smaller systems could become the next IEDs – low-cost, low-tech weapons that are only of limited lethality individually but can cause considerable attrition when used in large numbers over time.”
In all, 87 nations in the world today possess drones and conduct surveillance…
Down the ages weapons of war have become increasingly lethal providing an operational edge to the side which possessed technological superiority. World War I witnessed the introduction of aircraft that were employed as a platform initially for reconnaissance and later for bombing, aerial combat and chemical warfare. In World War II, the use of aircraft to shatter the morale of adversaries proved to be a game changer. This was witnessed in the bombing of London by Nazi planes, the devastation of Dresden by the British and the nuclear devastation of Hiroshima and Nagasaki by the US that led to surrender by Japan.
The game changer for any future war will be the Unmanned Aerial Vehicles (UAVs), also known as “drones”. Armed drones such as the Predator are already in use by the US against the Al Qaeda in Yemen and Pakistan. The Israeli armed forces believe that the drone is the future war-horse and the country with the best drone technology would be the winner in a future war. The Israeli Air Force has therefore been re-equipping fighter squadrons with UAVs. So far, the USA, Britain and Israel are the only nations to have fired missiles from drones.
UAVs are also shifting from purely military to civilian roles such as aerial survey, weather monitoring, disaster management and law enforcement. The US Association for Unmanned Vehicle Systems has estimated that the commercial drone industry will create over 100,000 jobs and generate over $82 billion over the next decade. The use of drones has however raised serious concerns about safety of civilian air traffic as also infringement of privacy. Regulations need to be suitable modified to address these concerns.
The demand for UAVs is expected to quadruple by the end of this decade…
Several countries employ drones today. China monitors Japanese activities near the disputed islands in the South China Sea as also industries violating pollution laws. Turkey tracks Kurdish activity in Northern Iraq, Bolivia locates cocoa fields in the Andes and Syria monitors activities of rebels. National borders are now monitored by drones in many countries.
In all, 87 nations in the world today possess drones and conduct surveillance either over their own territories or beyond. Of these, 26 have either purchased or developed drones equivalent in size to the US MQ-1 Predator. Considerable work is also being done on Micro Air Vehicles that are small aerial vehicles with flapping wings. Israel is the second largest drone manufacturer after the US. India too is developing drones that will fire missiles and fly at 30,000 feet. Already operating Chinese drones for surveillance, Pakistan now plans to acquire armed drones from China. Iran has a drone that Ahmadinejad the former President described as the “Ambassador of Death”. Iran brought down an American drone by hacking into its communication nodes. The US is developing a carrier-based drone to provide sea-based support in the Pacific.
Dutch scientists have developed the world’s smallest autonomous flapping-wing drone, the DelFly Explorer, a dragonfly-like machine. Using two tiny low-resolution video cameras, replicating 3-D vision and linked to an onboard computer, it can avoid flying into obstructions. The DelFly Explorer has a wingspan of 28 cm and like an insect, can fly around plants enabling it to detect ripe fruits or pest infestation.

With success in the employment of UAVs recorded by the US in the wars in Iraq and Afghanistan as also by Israel in several operations, the demand for UAVs is expected to quadruple by the end of this decade. Germany, Italy and South Africa have joined Israel in exporting drones. Many countries are now launching their own drone manufacturing programmes. Global spending on the technology is expected to jump from an estimated $6.6 billion this year to $11.4 billion in 2022.
As a weapon of war, apart from keeping own personnel out of harm’s way, an armed drone is cost-effective. For example, the MQ9-Reaper, from US General Atomics Aeronautical Systems costs $10.5 million while an F-22 fighter jet costs $377 million.
Israel, a pioneer of drone technology, has emerged as a major exporter of aircraft and accessories…
China is getting into the game of exports of drones. Zhang Qiaoliang, a representative of the Chengdu Aircraft Design and Research Institute, stated that since the US does not export armed drones, China would take advantage of this gap in the market.” According to the Centre for New American Security, in the 21st century, the US will be focusing on cyber warfare tools, guided munitions and mass production of automated drones, fleets of which would be stealthily flying over battlefields. US defence strategy is now based on technological superiority over potential adversaries.
Increasingly reluctant to put ‘boots on ground’ the US would resort to the use of armed drones in future battles. This is even now a reality to some extent, when in combat zones in Iraq and Afghanistan drones are being flown by controllers sitting in Nevada. Killer drones such as Predator which have been widely used by the US in recent times in Pakistan and Yemen to deal with “terrorists”, have been causing collateral damage resulting in loss of innocent lives, something that has made the US much hated in these countries.
Drones can be used for missions currently undertaken by manned aircraft such as Close Air Support, Intelligence, Surveillance, Reconnaissance (ISR), air interdiction, maritime strike, communications relay, delivery of cargo, aerial refueling, combat search and rescue. Next-generation drones are expected to have multi-mission and all-weather capabilities with autonomy. Unlike the current drones which have primarily operated in benign environment, in future, they may have to operate in hostile environment. One important aspect is protection of datalinks with the drone by encryption. In mission mode, drones can be made modular, an ability to mix and match weapons and sensors to meet mission requirements.
RQ-4 Global Hawk
United States
RQ-4 Global Hawk. It provides communications relay with the Battlefield Airborne Communications Node payload and a multi-intelligence collection capability through a combination of electro-optical/infrared and Synthetic Aperture Radar (SAR) imagery and a Signals Intelligence payload. They are also capable of long-range, high-resolution SAR imagery and ground moving target indicator.
RQ 180. Resembling the X-47B, this is a stealth drone being developed by the USAF for long-range reconnaissance missions. Currently in the testing phase, it could be operational by 2015. It was developed for ISR missions but could also be capable of electronic attack missions. It is designed to fly at high altitude and has an endurance of 24 hours. It has a 130-foot wing span and a “cranked kite” stealthy design to enable it to slip past enemy radar.
The game changer for any future war will now be the Unmanned Aerial Vehicles (UAVs), also known as “drones”…
BAMS-D. The US Navy’s Broad Area Maritime Surveillance Demonstrator (BAMS-D) unmanned aircraft supports intelligence-gathering missions in the Middle East. Based on the Global Hawk unmanned aircraft system designed for land surveillance, the BAMS-D systems were modified to work in a maritime environment.
Taranis. Of stealth design, the Taranis UAV can manoeuvre in ways that would cause a human to black out if they were onboard. And crucially, it is a step on the way to drones that can make autonomous targeting decisions.
VTOL. DARPA is developing a UAV called Aerial Reconfigurable Embedded System (ARES) capable of Vertical Take-Off and Landing (VTOL) which would carry one of several types of detachable modules, each designed for specific missions such as ISR, casualty evacuation and cargo resupply. It will have flexible, terrain-independent transportation that avoids ground-based threats. The final variant would be a drone that can buzz around air space connecting to a variety of modules such as vehicles or special container units. The ARES drone will be utilised as a UAV that would be able to set military units down in dangerous environments. It was created as a ground vehicle that is capable of configuring into a VTOL air vehicle that provides sufficient flight performance and range with respectable payload. The US Department of Defence is funding work on unmanned combat aircraft, including Northrop Grumman’s X-47, a diamond-shaped drone that can operate from aircraft carriers.
Small Unmanned Aircraft Systems (SUAS). These include the RQ-11 Raven and Wasp-III. They can be operated either remotely or on pre-programmed autonomous routes and can be expendable or recoverable. Some like MQ-1 Predator, MQ-9 Reaper, RQ-4 Global Hawk and RQ-170 Sentinel can carry a lethal or non-lethal payload. Over 100 of them are in service in the USAF.
The IAI Harop is an Unmanned Combat Air Vehicle (UCAV) which, instead of holding a separate high-explosive warhead, is itself the munition…
Israel
Israel, a pioneer of drone technology, has emerged as a major exporter of aircraft and accessories. A report by Frost & Sullivan states that from 2005 to 2012, Israel exported $4.6 billion worth of aircraft, payloads, operating systems as well as command and control caravans. US overseas sales for the same period were around $3 billion. Drones proved effective in the wars in Gaza, providing its troops eyes over its enemies in congested urban areas of Palestine and are lauded for saving the lives of dozens of soldiers. They also keep watch on neighboring Syria and Lebanon.
Israel Aerospace Industries (IAI), Elbit Systems and Aeronautics Defense Systems have begun producing drones first for Israel’s military, then branching out worldwide. Israeli drones have flown in conflict zones around the world, from Afghanistan to Mali. Britain and Brazil are among the biggest clients. It is reported that a major Israeli deal with India for UAV upgrade is worth $958 million. IAI, considered the leading Israeli unmanned aerial system exporter, sells drones to 49 customers worldwide and 80 per cent of its UAV products are destined for foreign markets.
Heron TP. The IAI has produced one of the world’s largest drones, the Heron TP, which has a wingspan of 26 metres and endurance of 45 hours. It is equipped with a radar that can scan swaths of territory even during the most inhospitable weather conditions. Software can detect movements on the ground in real-time. A laser beamed from a drone can guide a missile fired from a nearby jet. Cameras transmit high-definition footage of enemy activity below.
IAI Harop
Harop. The IAI Harop is an Unmanned Combat Air Vehicle (UCAV) which, instead of holding a separate high-explosive warhead, is itself the munition. It is designed to loiter over the battlefield and attack targets by self-destructing into them. The IAI Harop can be launched from ground, sea or air. Unlike the fully autonomous Harpy, the Harop is remotely controlled. The Harop features two guidance modes. It can either home in on radio emissions with its anti-radar homing system or the operator can select static or moving targets detected by the aircraft’s electro-optical sensor. The latter mode allows the Harop to attack radars that are shut down thus not providing emissions for the aircraft to automatically home in.
Super Heron. The Super Heron is an upgraded version of the “Shoval”, the first Heron-type drone that entered service in 2007. It features a heavy fuel engine and a propulsion system that enables it to operate at an altitude of 30,000 feet, fly 1,000 km when linked to satellite communications and remain aloft for 45 hours. Among other features, it has triple-redundant avionics, processing capabilities, operational flexibility and simple integration of more diversified payloads. It has been used in Intelligence, Surveillance, Target Acquisition, Reconnaissance (ISTAR), maritime patrol and other missions.
The Heron family continues to be dominated by the Heron TP, also known as Eitan, a fourth- generation craft currently with the Israeli Air Force. It can be armed with missiles for long-range strategic strike. As per IAI, its various drones have accumulated over 1.1 million operational flight hours around the world, while the Heron family has accumulated 250,000 operational flight hours worldwide.
China
The first drone was designed and manufactured in 1958. It however undertook serious development of the pilotless aircraft in the 1960s. One of the first Chinese UAVs was partially developed by reverse engineering a “Firebee” UAV that was lost over China. China also acquired Russian Lavochkin target drones. By the 1980s, China had developed the Changkong (CH)-1 drones, WZ-5 high altitude photographic reconnaissance aircraft and small remotely controlled aircraft D4s.
The PLA Navy is exploring the possible applications of VTUAVs including their use in anti-submarine warfare…
The pilotless aircraft design and research organisations were founded in the three universities, Xian’s Northwest Polytechnic University and the Beijing and Nanjing Universities of Aeronautics and Astronautics which have been used as the bases with the capabilities of design and small-scale production. In addition to satisfying the needs of both military and civilian applications, Chinese drones are now entering the world market. Initially UAV programmes were based on US and Russian designs.
However, China has now designed mini, micro, VTOL and flapping-wing UAVs. In the past few years, China has produced dual-use versions, such as the W-50 UAV for reconnaissance, radio-relay and electronic jamming. The ASN-206 is used for night reconnaissance, battlefield surveillance, target location, artillery fire correction and battle damage assessment. Over 40 different types of UAVs have been manufactured in the past 50 years and a total over 1,500 UAV were delivered by Chinese firm ASN that commands over 90 per cent of the Chinese UAV market. Authoritative estimates are that the PLAAF alone had over 280 UAVs in service by 2011.
The TianYi is modeled after a Global Hawk class High Altitude, Long Endurance (HALE) UAV and began testing in 2009. It is a new Chinese UAV design with a 60,000-ft. cruising altitude, 480km radar range and low radar reflectivity that could serve as the targeting node for China’s anti-ship ballistic missiles. The Guizhou WZ-2000, displayed at the 2000 Zhuhai airshow, is a squat twin-jet powered delta-wing High Altitude Long Endurance UAV, which has evolved into a medium-sized UAV and appeared to form the basis for an armed turbofan powered UCAV similar in size to the US General Atomics MQ-9 Reaper.
Dark Sword
The State Oceanic Administration, part of the Coast Guard, has announced the setting up of 11 UAV bases, one in each of China’s coastal provinces expected to be operational by 2015. It completed trials in 2011 that used UAVs in Liaoning Province to take aerial imagery of 980 square miles of sea area. Reportedly, the PLAAF has already begun to deploy UAVs for missions over the East China Sea, notably to an air base near Shuimen, Fujian. More recently in September 2013, the PLA Navy began UAV flights near the Senkaku Islands.
The ASN-15 is a UAV similar to the US RQ Raven, a small, man-portable system for basic battlefield ISTAR duties. The ASN-209 medium altitude and medium endurance UAV comparable to the US ScanEagle, a larger ISR system than the Raven with up to 20 hours of endurance for long-range battlefield and maritime surveillance. The ASN-209 is probably the same aircraft as the “Silver Eagle” which took part in naval exercises over the South China Sea in 2011.
The Yilong has already successfully entered the international market as a low-cost Chinese system…
A PLA Navy frigate has been photographed in 2012 operating what was probably one of the 18 Camcopter S-100s China acquired from Austrian company Schiebel, supposedly intended for civilian use. Another Vertical Takeoff and Landing Tactical Unmanned Aircraft (VTUAV), the SVU-200, made its first flight late last year, while a third unmanned helicopter, the V750, recently entered civilian service. The PLA Navy is exploring the possible applications of VTUAVs including their use in anti-submarine warfare.
The Yilong/Wing Loong “Pterodactyl”, built by the Chengdu Aircraft Design and Research Institute, and the China Aerospace Science and Technology Corporation’s (CASC) CH-4 are similar to the US MQ-1 Predator and MQ-9 Reaper drones which are Medium Altitude, Long Endurance (MALE) UAVs best known for conducting lethal operations in Pakistan and elsewhere. The Yilong is primarily regarded as a Reaper-style strike aircraft while the CH-4 is more of a multi-role aircraft that will be deployed by civilian agencies as well as by the military, for surveillance purposes though it can also be weaponised. These two UAVs appear to be in the same class as the CH-91, built by Aerospace Long March International, an ISTAR system already under production and the more advanced CH-92, which is due to enter production soon.
The Chengdu Aircraft Industry Corporation is developing the Soaring Eagle, an analogue of the RQ-4 Global Hawk, Washington’s HALE UAV. China is thought to be working on a stealth UAV called the Wing Blade, similar to the US RQ-170 Sentinel and a stealth UCAV called the Dark Sword, analogous to X-74B. China is also experimenting with a new generation of nano UAVs, like the Black Hornet micro-helicopter with the British Army.
The Predator-style CH-4 in particular is being pushed for export. The system is part of CASC’s CH “Rainbow” family of drones and is understood to be an upgraded version of the CH-3 UAV, which China has already sold to Pakistan. The CH-4 carries four missiles and has an endurance of 30 hours. The Yilong has already successfully entered the international market as a low-cost Chinese system. A US Predator costs around $4.5 million while a Reaper is closer to $10 million for countries that manage to obtain clearance to buy them. Chinese claim that their equivalent UAVs cost less than $1 million making them a highly affordable for a host of international customers, especially those unable or unwilling to source US and Israeli technology for reasons of cost or otherwise.
At present, Pakistan has an indigenous UAV capability but its drones cannot launch guided missiles…
As per a retired Deputy Chief of the PLA General Staff, China is likely to field over 1,000 medium and large-sized UAVs in the coming years. The US has also been accusing China of using cyber espionage to steal drone technology from the US in developing military drones. Manager of threat intelligence at FireEye, Darien Kindlund, who monitored the espionage, said that the Chinese campaign is the largest to be solely focused on drone technology. There has been official confirmation that drone technology had been stolen by hackers.
In recent years, control of multiple UAVs flying in formation has become a challenging subject for inter-disciplinary research while autonomous formation flight is an important research area in the aerospace field. The main motivation is the wide range of possible military and civilian applications, where UAV formations could provide a low-cost and efficient alternative to existing technology.
China sees drones as a platform to wage war at the “highest level of conflict”. Chinese documents suggest that the PLA envisions “attacking US aircraft carrier battle groups with swarms of multi-mission UAVs with initial waves of decoy drones followed by swarms of strike drones that would often be shot down during their mission.” China has undertaken a number of studies on the employment of UAVs to hit US aircraft carriers.
There are several public sector companies involved in developing UAVs in Pakistan…
China tested its first stealth combat drone “Sharp Sword” on November 22, 2013, making China the fourth power capable of putting a stealth drone in the sky after the US, the European Union and Britain. Images posted online showed a sleek grey delta-wing aircraft apparently powered by a jet engine and resembling an American combat drone. According to Jane’s Defence Weekly, there are some indications China may already be exporting know-how to Pakistan given the design similarities between Chinese drones and Pakistan’s Shahpar UAV.
Pakistan
Having flown its first UAV in 1992, Pakistan’s drones currently use ‘line of sight’ radio communication rather than satellite communication. The Shahpar has a maximum range of 250 km. At present, Pakistan has an indigenous UAV capability but its drones cannot launch guided missiles. The laser guided technology helps it to identify targets and then relay that information to a helicopter gunship or combat aircraft. Pakistan first began weapons tests early 2012 with the Falco, an Italian drone that has been modified to carry rockets. The military has also been conducting similar tests with the country’s newest drone, the Shahpar that has a wingspan of seven metres and 50-kg payload capacity.
As Pakistan lacks laser-guided missiles like the Hellfire and advanced targeting system of the US Predator and Reaper drones, the military has been using unguided rockets that are much less accurate. While Hellfire missiles are said to have pinpoint accuracy, rockets used by Pakistan have Circular Error Probability (CEP) of 30 metres at best and an unexpected gust of wind could take them 300 metres from their intended target. Even if Pakistan possessed Hellfires, the missile’s weight and drag would be a challenge for the small indigenous drones. China has offered to sell Pakistan an armed drone which can carry two laser-guided missiles or bombs, but its capabilities are as yet unproven.
In 2004, Pakistan produced a UAV called Jasoos-II, a state-of-the-art UAV to be employed for real-time information…
The latest UAV built with Turkish and Chinese help, is called the “Burraq” named after a mythical flying horse. The PAF and government-owned defence conglomerate, the National Engineering and Scientific Commission, is flight-testing a new UAV to be equipped with a laser designator and laser-guided missiles. The current efforts are to upgrade various older UAVs with Chinese help. The military’s most capable UAV is the Selex Galileo Falco, which can laser-designate targets for other platforms but cannot deliver guided munitions.
Turkey, with whom Pakistan has an agreement to cooperate on UAV development, is seeking an armed UAV, preferably the Predator or MQ-9 Reaper. This UAV may someday be armed with the UMTAS infra-red guided anti-tank missile being developed by the Turkish firm Roketsan to arm the T-129 attack helicopter. According to Richard Fisher, China specialist and Senior Fellow at the International Assessment and Strategy Centre in Washington, Pakistan could simply produce China’s new CH-3 UCAV or co-produce any number of Chinese components to assemble a unique UCAV. He has also said that China has developed the unique AR-1, a 45-kilogramme, laser-guided attack missile, apparently designed specifically for light-winged or helicopter UCAVs.
Integrated Dynamics is a private company in Karachi with a 90,000 sq. ft. research facility. The Managing Director R.S Khan is a Masters in Aeronautics and Astronautics from MIT. According to him, drone technology is being developed in Pakistan for the last 20 years. The company’s customers include the Pakistan armed forces as well as foreign buyers from the US, Australia, Spain, Italy and France. Khan is confident that Pakistan can make an armed drone in a few years. Apart from Integrated Dynamics, East-West Infinity, Satuma and Global Industrial Defense Solutions (GIDS) are in the drone manufacturing business.
The US has been reported to have 163 UAV programmes in operation, compared to 50 by France, 31 by Israel and 25 by Pakistan…
There are several public sector companies involved in developing UAVs in Pakistan including the Pakistan Aeronautical Complex (PAC), Air Weapons Complex (AWC) and National Development Complex (NDC). The PAC’s Uqaab drone in use by the Pakistan Army is being upgraded with Chinese help to carry a weapons payload. Other PAC UAVs include the Bazz and Ababeel. AWC’s Bravo+ UAV is in use of the PAF. In 2008, the Pakistan Navy completed trials of the Austrian Schiebel Camcopter S-100 and Swedish Cybaero from a Pakistani frigate in the Arabian Sea.
The EWI’s Heliquad UAV is considered a stealth design because of its small size and Whisper Watch signals intelligence package, which is capable of picking up communication signals. ID’s Nishan Mk1 and TJ1000, Vision MK1 & MK2, Tornado, Border Eagle, Hornet, Hawk and Vector are also popular models employed by the armed forces for reconnaissance missions and target practice. Each model varies in range and endurance. Satuma’s UAVs with similar capabilities are called Flamingo, Jasoos and Mukhbar. For its part, the GIDS is developing the Huma-1 UAV and its own version of the Uqaab. None of these are reported to be capable of firing weapons. Moreover, none of the above-mentioned facilities are involved in large-scale production of UAVs.
On March 24, 2008, Pakistan announced the successful completion of flight tests of a new UAV, the Uqaab. The design looked very similar to models offered by a Pakistani firm, Integrated Dynamics, which has been producing smaller (under 500 lbs) UAVs for the government and commercial market since 1997. The Uqaab also appears similar to the US Army RQ-7B Shadow 200. Each Shadow 200 UAV platoon has 22 troops and operates three to four UAVs, plus the ground control equipment. Typically, each combat brigade has one Shadow UAV Platoon.
The Integrated Dynamics UAVs appear to operate in a manner similar to the Shadow 200, which is not high tech, just good engineering and quality manufacturing. The 350-pound Shadow 200 UAV costs $500,000 with an endurance of five and a half hours and carries day and night cameras. Flying at 15,000 feet, the Shadow can be safe from hostile ground fire in hostile territory. Integrated Dynamics has many export customers, including some in the US.
RQ-7B
In 2004, Pakistan produced a UAV called Jasoos-II, a state-of-the-art UAV to be employed for real-time information and situational awareness. Bravo+, variant of Jasoos II UAV was inducted in the PAF in 2004 and has proved to be a reliable system that is extremely easy to operate and maintain. It can take off and land conventionally from a runway under manual control. Once airborne, the UAV can fly autonomously whereas mission can be controlled using line-of-site data links. Jasoos-II can carry a variety of controllable payloads of up to 20kg with an endurance of over five hours. The standard variant of Jasoos-II is equipped with a day/low light camera pod capable of being steered 360 degrees in azimuth and +/- 105 degrees in elevation giving it the capability of panoramic viewing. Bravo+ is currently in production for the PAF as their primary work-horse for UAV Operations and Training Programme.
The US is the leader in UAV technology followed by Israel and European countries…
The Flamingo is a medium range UAV with an endurance of six to eight hours with a payload capacity of 30 kg. The Flamingo is equipped with an Avionics suite which controls the UAV during its beyond visual flight. The UAV flies a pre-programmed path which has been fed into the onboard mission computer without any assistance from the ground. The mission can be manually altered at any time during the flight by a short radio transmission from the ground. The Flamingo’s operational radius is only constrained by the line-of-site data links. In case of silent operation, the UAV can reach 400 km radial distance and return to base. The line replacement unit architecture of the UAV makes it easy to maintain in field conditions without relying heavily on backup support.
The Mukhbar, is a scaled-down version of Jassos II, to meet the operational requirement of a short-range reconnaissance UAV. The UAV fuselage and wings are manufactured using non-metallic materials thus minimising radar signature. The UAV is equipped with auto-pilot, telemetry, video transmitter and daylight camera. It can be operated using a portable ground control station with waypoint navigation within a radius of 30 to 50 km.
According to an Inter-Services Public Relations news release, Pakistan has successfully conducted a final test flight of its indigenously developed UAV “Uqaab”. A statement issued on the occasion said, “The performance of the Uqaab can be compared to any of modern state-of-the-art UAV in its category. The successful flight test is a reflection of Pakistan’s technical prowess in the field of UAV technology.”
The US has been trying to develop counter-drone technology by use of lasers to bring down the drones…
There is an effort to upgrade the Uqaab drone made by PAC to an armed drone, with the Chinese help. The Baaz and Ababeel are also made by PAC. Bravo+ made by AWC is used by PAF. The Pakistan Navy completed trials of the Austrian Schiebel Camcopter S-100 and Swedish Cybaero – from a Pakistani frigate in the Arabian Sea. The EWI’s Heliquad UAV is considered a stealth design because of its small size and Whisper Watch signals intelligence package, which is capable of picking up radio and other communication signals Satuma’s UAVs, with similar functionalities, are called Flamingo, Jasoos and Mukhbar. The GIDS is developing the Huma-1 UAV and its own version of the Uqaab. None of them are reported to be capable of firing arms. Moreover, none of the above-mentioned facilities are involved in large-scale, mass production of UAVs.
Conclusion
There is little doubt that UAVs are becoming increasingly important. The US is the leader in UAV technology followed by Israel and European countries. However, the gap between the US and other nations in the technology is enormous and cannot be closed any time soon. While UAVs that can fly for up to 60 hours have been developed, the Americans are working on a UAV that would be maintenance-free and have an endurance of up to five years, giving them an unlimited advantage in terms of reconnaissance. At the moment, however, one of the most advanced UAVs is the 12,110kg Northrop Grumman’s Global Hawk that has a range of more than 22,000 km. The US has been reported to have 163 UAV programmes in operation, compared to 50 by France, 31 by Israel and 25 by Pakistan.
High operational reliability is an essential prerequisite for UAVs. A good engine is the most difficult aspect in the designing of a UAV. Designers have to make sure that the engine can support the airframe and the UAV has a low signature through low vibration. It should be able to support long-endurance missions over the target. Another area of operational reliability for a UAV comes from its airframe, which should be able to support the mission in all types of conditions, especially rough weather. There is a flipside to the development of the drones globally. A recent report by the Rand Corporation warned that, in the future, terrorist groups might be able to buy small, armed drones, “Smaller systems could become the next IEDs – low-cost, low-tech weapons that are only of limited lethality individually but can cause considerable attrition when used in large numbers over time.”
The US has been trying to develop counter-drone technology by use of lasers to bring down the drones or develop systems to jam the radio signals used for guiding the drone. It holds an annual exercise called Black Dart which looks at ways to counter hostile drones, particularly small drones. But as on date, there is no counter-drone technology in the market.
