  • Caracal’s CSR sniper rifle

UAE small arms manufacturer Caracal, a Tawazun subsidiary, is showing its two latest products for the first time here at IDEX. One is the latest member of the successful Caracal pistol series and the other is a sniper rifle.

Caracal H is the latest pistol product, completely designed and developed in the UAE and drawing on the experience and success of the striker-operated Caracal C, F and SC pistols.

The primary aim of the new weapon is to provide the levels of performance achieved by strikeroperated pistols in a hammeroperated gun, thereby gaining the benefits of both.

Chambered for 9x19mm ammunition, Caracal H is the lowest-profile hammer pistol available. It can be held very close to the barrel, improving multishot accuracy by reducing the tendency of the barrel to climb. It can use Caracal’s Quick Sight, or adjustable sights, the latter being of very low profile to avoid snagging in quick-draw situations.

One of the benefits of a striker operated gun is the much shorter lock time when compared with traditional hammer weapons, with a corresponding improvement in accuracy. The Caracal H has reduced the lock time to values comparable to those of striker guns, while retaining the hammer’s benefits of a smooth, single-action release and the ability to be cocked and decocked with a finger or thumb. Development began in January 2010 and early firing trials have drawn considerable praise.

The weapon is expected to be production ready within the year.

Caracal could easily adapt the weapon to 9x21mm ammunition, and is investigating other calibres.

The Caracal Sniper Rifle (CSR) is being shown here in prototype form, development having started only late last year.

The weapon has been designed to be modular and versatile, with comfort and ease of use as important design drivers. Grips and accessories can be switched easily, and the stock adjusted to suit any firing position, without the need for tools. The rifle can be converted to a folding stock weapon, while a bipod can be mounted at any desirable position. It has low-profile sighting mounts for standard barrels, or a higher position for barrels fitted with suppressors.

Currently it is configured for 0.308 Win ammunition, although 0.300 Win (Mag) is an option. Standard magazine capacity is 10 rounds and effective range is about 600m.

Caracal is initially offering two versions, the CSR Basic with full-length (600mm) barrel, and the CSR Compact with a 510mm barrel, intended primarily for law enforcement agencies. CSR is aimed initially at the Middle East market, and should be ready for production by the year end. Caracal (Hall 5, Stand A10) is also developing a semi-automatic 9mm carbine, the CC10. This weapon has a 410mm barrel that can be changed rapidly and a highly ergonomic design. It can accept magazines with 13, 15, 18 or 30-round capacities.

Inventors, Jung Won Seo, Jae-Woo Park, Keong Su Lim, Ji-Hwan Yang and Sang Jung Kang, who are scientists at the Korean Advanced Institute of Science and Technology, have created the world’s first transparent computer chip.
The chip, known as (TRRAM) or transparent resistive random access memory, is similar to existing chips known as (CMOS) or metal-oxide semiconductor memory, which we use in new electronic inventions.The difference is that TRRAM is completely clear and transparent. What is the benefit of having transparency?
“It is a new milestone of transparent electronic systems,” says Jung Won Seo. “By integrating TRRAM with other transparent electronic components, we can create a total see-through embedded electronic systems.”
The technology could enable the windows or mirrors in your home to be used as computer monitors and television screens.
This technology is expected to be available within 3 to 4 years.

Flash Dock HotShoe Smartphone doc

A smarter DSLR.
There when you need it.

What happens when you marry an iPhone or SmartPhone with a DSLR ?
It turns out, your iPhone or your smartphone could do many things for you on the go.
In fact, they were built for that, and guess what. There is a socket on your DSLR that you don’t use all the time; the HotShoe socket, or cobra flash socket.
So at Pocketdemo, we’ve created that dock that holds your smartphone in that HotShoe socket.
And because your SmartPhone is right there when you need it, then it is there to work for you automatically.
Let’s start with the 2 most important features it will bring to your DSLR: Geotagging and Sharing pictures

Sharing pictures.
Your DSLR with a 3G/4G connection!

What if you could share a High Quality DSLR picture by E-mail, SMS or via cloud services like iCloud or DropBox ?
That is something you’ve done for years with your camera phone, but never did with your DSLR.
That is about to change when combining the Flash-Dock & EyeFi SD Cards.
EyeFi cards are SD Cards that both store your pictures and feature a WIFI chip.
Using the EyeFi app on the AppStore or Android Market, you can receive in real time the pictures you are taking directly on your SmartPhone. Once on the phone, you can send them to whoever you want through the 3G/4G networks.

Geotagging pictures.
With GPX files.

Your smartphone has a built-in GPS and most DSLR don’t.
Did you know that your smartphone could record your tracks into a file called GPX file?
Well, that file is then read by iPhotoApertureLightroomPhotoshop ElementsPicasa and most photo library softwares and what those softwares do is merging this GPS data with the metadata of pictures you have taken during that trek, walk, expedition, trip, you name it.
It’s that simple! … and it’s FREE
Your smartphone works for you while you take pictures.

Geotaging pictures.
With bluetooth.

Some Add-on devices like BlueSLR plug into your DSLR GPS connector.
Since your Smartphone also has a bluetooth connection, it can send in real time location informations to your camera that in turns will use it to geotag your pictures.
It works the same way as if you had a GPS receiver plugged into your DSLR, only cheaper.
And unlike geotaging using .gpx files, there is no need to do anything in your picture library software as all pictures on your card already contain location informations.

5D Mark II assistant.
Helping the low light AF issue.

For DSLR cameras like the Canon 5D Mark II, low light autofocus can be challenging.
Use your smartphone’s flash to help your camera autofocusing or simply use it as a softer flash than traditional cobra flashes.

The list goes on and on.
Get your DSLR smarter as new apps and accessories become available.

All smartphones feature an accelerometer and you’ll find tons of free apps like this one that bring a level functionality to your DSLR.

Companies like bluemic provide plug-in professional quality recording microphones for iPhones. And that’s perfect for the indie film maker that you are.

Flash-Dock is equipped with the standard thread for all tripods in the world, so you don’t need to buy a specific


ATK has unveiled this GPS/SAL guided weapon, believed to be the G2M.

ATK is developing a lightweight precision guided munition, compact and light enough to be carried by the dozens or even hundreds by unmanned aerial aircraft. The new glide weapon is packed into a conformal container launcher carried under the wing of the Shadow, fitted on top of the strut root. Upon release the weapon’s fins are extracted and three airfoils pop into place, as the weapon glides on its path to the ground. As the three laser detectors are activated, they seek laser signals reflected from the designated target. Once the laser spot is detected, the weapon’s flight control processor computes the necessary corrections and activates the tail fins to point the weapon on the course homing in on the spot, hitting the target with high precision.

The weapon weighs about six pounds (2.7 kg). Its hand-grenade size warhead makes more than half that weight (about four pounds or 1.8 kg). The resulting effect offers maximum lethality against exposed targets, with minimal collateral damage to their surrounding.

Persistence and immediate response close air support based on such weapons has the potential to transform combined air/ground operations, as UAVs loitering above a ground combat element could continuously support ground forces through sustained combat engagements, without the logistical and operational burden when rotating through rearmament or replenishment cycles. Brigades could rely on their own Small UAVs assets like the Shadow, each carrying four weapons in addition to the standard ISR and radio relay payloads. Larger drones will employ multiple ejector racks packing 12 weapons or more, each loaded rack could be carried under a pylon currently carrying Hellfire missiles. Therefore, an MQ-1A Predator currently carrying two Hellfires will carry 24 of the new weapons. A similar load will be carried by the MQ-5B Hunter, while the MQ-1C Grey Eagle will be able to carry twice that load. The Air Forces’ MQ-9 Reaper will be able to carry 72 units and the A-160 destined for the Special Operations Command will haul over 200 such weapons.

The miniature guided weapon currently under development could, potentially, replace current cluster weapons banned by international treaties. When employed in weapon systems, individually targeted guided weapons could be directed to scatter over the area to focus on specific target location, guided by GPS – or disperse over a specific area in a pattern maximizing the desired effect. Optional carriers such as new cruise missiles, or loitering weapons, will be able to employ such guided submunitions to attack multiple targets along their flight path, on a single mission.

EO-Guided Spike Missile

EO-Guided Spike Missile

The miniature electro-optically guided, ‘fire and forget’ SPIKE missile was developed by the US Navy Weapons Division of the Naval Air Warfare Center, Weapons Division (NAWCWD) with assistance of DRS Technologies. Originally designed as a man-portable weapon for the Marines and the Navy’s special operations force, Spike fills a critical niche for a low-cost, lightweight guided weapon for U.S. ground forces.

A modular, low-cost, high precision missile capable of engaging ‘asymmetric aggressors’ in complex terrain, at ranges exceeding 2 miles, with high precision, and minimal risk of collateral damage. The missile was designed as very low cost weapon, with unit cost goal of US$5,000. The Spike weighs about five pounds (2.26 kg), and is 25 in. (63.5 cm) long. It uses fire and forget guidance using a general purpose strap-down electro-optical seeker. It was designed as a shoulder fired tactical missile or a UGV, UAV boat or ship launched weapon. The warhead weighing about 1 pound (450 gr.) is located at the center and employs Explosively Formed Projectile effect to drive a focused yet lethal effect. NAWCWD plans to test the Spike missile with a new lightweight weapons management system (WMS) developed for small UAVs.

The missile uses EO / Semi-Active Laser (SAL) seeker to engage laser designated targets from a distance of two miles. It’s potential applications go beyond ground combat; it is a realistic armament choice for tactical unmanned aerial vehicles and a force-protection weapon to defend surface ships from small-boat swarms or light aircraft.

The missile performed its first controlled flights in 2005. SPIKE will offer safer, more accurate alternative to rocket propelled grenades (RPGs). The compact system is tailored for man-portable operations. Three missiles and a launcher could fit in a standard military backpack. Due to its light weight, Spike is considered to arm unmanned systems. According to John Baylouny, vice president of DRS Technologies, Spike missile could be used on almost any UAV and that “future spirals” in the program are expected to involve putting Spike on unmanned aircraft. Spike has already been tested with the DRS Sentry HP drone at Eglin AFB, Florida, as part of US Air Force UAV Battlelab evaluation.

Switchblade – Miniature Loitering Weapon

Switchblade – Miniature Loitering Weapon

US Forces in Iraq and Afghanistan are beginning initial deployment of the Switchblade  unmanned aircraft system. A product of AeroVironment, the aircraft is light enough to be man-packable, simple enough to be deployed in minutes and can fly off over the horizon sending back video. It can loiter and watch silently (it’s electric) and is so small that it is very difficult to detect at night, even at close range.

It has one more feature – it carries a warhead, so if a target of opportunity presents itself, the Switchblade has imaging sensors capable of identifying, tracking and guiding itself right to just that person, with minimal collateral damage.

Denoted as being “expendable” rather than “disposable”, the Switchblade is the first of a new breed of miniature kamikaze drones. As the system has very accurate tracking algorithms, the Switchblade is very good at locking onto and following targets, a capability that will no doubt be invaluable in the theaters of war in which they will be deployed. Small groups of soldiers will now have a much higher level of situational awareness plus the assistance of silent invisible birds of prey capable of striking from the darkness of night.

While the Switchblade will be the first such armed miniature UAS on the battlefield, its incredibly useful capabilities will

almost certainly see similar weapons being manufactured

Following the conclusion of DARPA’s Close Combat Lethal Recon CCLR projects the U.S. Air Force has embarked on a rapid acquisition program for a Lethal Miniature Aerial Munition System (LMAMS), offering the warfighter portable, non-line-of-sight precision strike capability against individual targets, ensuring high precision effect with a very low risk of collateral damage.

The program is run by the Rapid Acquisition Cell (RAC), the Air Force’s unit handling rapid acquisition and deployment of systems responding to urgent operational requirements. LMAMS will meet a requirement identified by the Special Operations Command, for a weapon system designed for small tactical units, capable of accurately engaging targets beyond the range of current organic direct fire weapons (ALGL, M2, M3 Carl-Gustaf, and AT-4). According to Air Force documents, LMAMS will increase lethality by quickly locating, tracking, and engaging time sensitive, fleeting targets, or enemy in defilade without exposure to threat precision small arms fire. ‘Absence of visual or acoustic launch signature is essential to maintain covert operation’ the document emphasized.

Both tube-launch or hand-tossed versions will be tested. These expendable, electro-optically guided weapons will be fitted with a small warhead. The miniature killer drone will be able to loiter quietly over the target for limited time, waiting for optimal conditions to attack, while maintaining constant communications with the operator, transferring live video of the target below. Once attack permission is granted by the user, the drone’s mission-control becomes a guidance system, employing automatic-target tracking to lock on target, descending through a fast, controlled diving guiding itself to hit the target with the highest precision.

Viper Strike

Viper Strike is a gliding munition capable of stand-off
precision attack using GPS-aided navigation and a semi-active laser seeker. It is intended for operations that require a flexible angle of inclination (steep or shallow), particularly in mountainous terrain or built-up areas where strict rules of engagement are in force. Its small size and precision provide for low collateral damage in cluttered urban environments.

The weapon was developed as a derivative of the autonomous Brilliant Attack Munitions (BAT) Submunitions during a quick reaction, nine-week program at Northrop Grumman’s Land Combat Systems facility at Redstone Arsenal, Huntsville, Ala.

The weapon is suitable for operations that require top-down attack, particularly in built-up areas where strict rules of engagement are in force. It requires a “man in the loop” to lase the target, either from the ground in sight of the target or from directly by the UAV, controlled from the ground station, a process which ensures the greatest possible accuracy and minimizes the chances of collateral damage.

The Viper Strike’s warhead is smaller than the hellfire’s, which is used with the US Air Force armed Predator UAVs, containing only four pounds of Anti-Tank High Explosive (HEAT) charge, for reduced collateral damage in an urban built-up area. It also has a self-destruct mechanism, to eliminate post-strike hazards. The final version of Viper Strike could be equipped with fragmentation belt as well as an optional blast fragmentation and thermobaric warhead.

By late 2004 the US Army deployed to Iraq some Viper Strike munitions with MQ-5 Hunter unit. There were no details about combat engagements of these weapons. In 2005 Northrop Grumman continued development of the weapon, and is preparing to test it with MQ-1 armed Predator and AC-130 gunships, which will use the weapon as a stand-off precision  guided munition (SOPGM). Ac-130 integration with Viper Strike is currently developed under a Special Operations Command (SOCOM) for an advanced technology demonstration (ACTD). The first phase of the program is scheduled for completion by December 2006. The weapon is being updated with additional GPS guidance system and fragmentation belt, placed around the shaped charge warhead. 

Small Air Bomb Extended Range (SABER)

Small Air Bomb Extended Range (SABER) from MBDA provides multipleis guidance methods enabling autonomous or semi-autonomous attacK

Two new versions of the Predator – the U.S. Army MQ-1C Gray eagle and the Air Forces’ MO-9Reaper , both from General Atomics, are changing the way the U.S. military addresses drone warfare. Both aircraft are designed from baseline for armed missions and capable in carrying more than the Predator’s two weapons. They can also carry multiple sensors, enabling the weapon’s operation to take place in parallel to other tasks.
The Reaper is configured as a true multi-mission aircraft. In addition to a load of multiple Hellfire missiles, the Reaper can also carry three types of ‘free fall’ guided weapons – homing in on their target at high precision by laser guidance Global Positioning Satellite (GPS).  These include the Joint Direct attack Munition(JDAM) used by the larger drones, or the Small Diameter Bomb(SDB) 

.Even smaller weapons can be employed by the Predator and Gray Eagle, including the Viper Strike from Northrop Grumman or

Small Air Bomb Extended Range (SABER) from MBDA. Both employ GPS-assisted laser-homing capability, turning it into a ‘glide weapon’, thus eliminating the signature of the weapon being launched. SABER can also be configured with rocket propulsion to cover even longer ranges. Both weapons employ dual-mode warhead, using blast-fragmentation or anti-armor shaped charge, for reduced risk in collateral damage. The GPS/INS segment is used for mid-course navigation, enabling the weapon to perform ‘off-axis’ turns, regardless to the direction it is launched at. When active laser designation is available, by remote element or the platform’s EO payload, semi-active laser seeking can also be used for the terminal phase, further increasing attack precision and effect. An alternative seeker employing TV/IR sensor with data-link communications enabling ‘man in the loop’ control is currently under development.

The Gray Eagle can carry four Hellfire missiles optimized with minimal rocket signature and a wider launch envelope. The typical range of such weapons and their all-aspect attack mode make them particularly suitable for use on UAVs, eliminating the need to preposition the UAV in a straight line with the target for launching.

The new version of the Hellfire designated AGM-114R was developed by Lockheed Martin to meet specific requirements for unmanned operations. The new missile incorporates a ‘multi-purpose’ warhead, enabling a single missile to engage target sets, currently covered by four different types of laser-guided Hellfire variants. Utilizing an integral inertial measurement unit, the AGM-114R can be launched at high aspect ratio, considerably shortening the firing preparation process. Other modifications have dealt with the weapon’s obsolescence, by replacing hardware circuits with software controlled functions, thus reducing the missile’s weight and improving its reliability.

While laser guidance provides weapons with precision and lethality, it also has inherent limitations, being susceptible to interference, countermeasures or error under certain operational conditions. Furthermore, target designation by laser is far from being a trivial task. The process requires considerable and continues coordination, with the entire process constantly prone to human and technical error.

The use of a dual-mode seeker, combining electro-optical (EO) and laser/GPS can overcome such limitations, at a price. In the US, two teams are competing for the future production of such missiles, known as  Joint Direct attack Munition(JDAM) which are already in development, but these are expected to be fielded primarily with manned platforms – Apache helicopters, and Super Hornets.

For the smaller weapons electro-optical (EO) guidance has sofar been considered a costly option reserved only for special missions. But state-of-the-art commercial off the shelf technology opens new capabilities for EO seekers. Dual-mode guidance utilizing imaging sensor as laser seekers has the potential to revolutionize laser guidance, by introducing low cost, light-weight yet highly accurate means for target acquisition and weapon guidance. Current laser designators employ pulse lasers to generate high-power laser beams.

A new type of laser designator is employing low-power laser diodes to generate Continuous Wave (CW) beams, operating at relatively low power levels and available for much lower cost.
