General Design


The vehicle is based on the BMP-3, but is slightly modified, using better armor and focusing more heavily on automation. The addition of medical capabilities to every vehicle is designed to reduce the bottleneck constraint of medical services and increase the survivability of the men in the event of an injury by decreasing the time needed to get emergency medicine (not having to rely upon a medical vehicle to arrive first).


Active Defense systems
The vehicle uses the Trophy active defense system, the Iron Fist active defense system, and the Iron Curtain active defense system. The use of multiple, overlapping defense systems help increase the systems readiness, and the redundant safety measures increase the likelihood of success of intercepting missiles and RPG's, as well as other shaped charge weapons. The Iron Curtain system uses a radar to detect the incoming round and cue the system. It then switches from armed-ready state to an armed state. As the round comes into close range, the optical sensor profiles the threat and tracks it within 1 cm (0.39 in) of accuracy to select an aimpoint and determine which ballistic countermeasure to fire. The countermeasure deflagrates the RPG warhead without detonating it, leaving the dudded round to bounce off the vehicles side. Because of its shelf-like design, the system can be modified to protect almost any surface, from the sides of the vehicle to all around protection, including a turret. Artis claims that the Iron Curtain can be enhanced to protect against “more challenging threats” like the RPG-29 and RPG-32 ‘Hashim’ multipurpose anti-tank grenade launchers, which utilize tandem warheads for penetrating tanks with explosive reactive armor. Iron Curtain should also be able to defend against ATGMs (Anti-Tank Guided Missiles). The system has 360° coverage, is multi-shot, low-cost, low power, lightweight, and rugged and reliable.The system, which began in 2005 as a DARPA program, is able to defeat threats even if fired from an extremely close range. It has undergone significant safety testing, including temperature and shock testing, and its software architecture has been approved by the U.S. military's Joint Services Weapons Safety Review Process. The countermeasure fires straight down or up, neutralizing the incoming threat within inches of the vehicle, separating the system from many others which intercept threats several meters out, resulting in minimal risk of collateral damage to dismounted troops or civilians. Iron Curtain is designed to be highly modular, and the system's radar does not need to track the threat; hence, a relatively inexpensive radar will suffice. To date, two radars have been integrated onto Iron Curtain: the Mustang radar developed by Mustang Technology Group in Plano, Texas and the RPS-10 radar, built by RADA Electronic Industries. In April 2013, the company announced it achieved a perfect score during rigorous government tests. “We proved not only that Iron Curtain defeats threats and saves lives, but the risk from collateral damage is minimal, especially when compared with the alternative," according to the company's CEO, Keith Brendley. He said the system is ready to be deployed onto battlefields.

The trophy active defense system uses a Elta EL/M-2133 F/G band fire-control radar with four flat-panel antennas mounted on the vehicle, with a 360-degree field of view. When a projectile is detected, the internal computer calculates an approach vector almost instantly, before it arrives. Once the incoming weapon is fully classified, the computers calculate the optimal time and angle to fire the neutralizers. The response comes from two rotating launchers installed on the sides of the vehicle which fire neutralizing agents, usually small metal pellets like buckshot. The system is designed to have a very small kill zone, so as not to endanger personnel adjacent to the protected vehicle. The system is designed to work against all types of anti-tank missiles and rockets, including handheld weapons such as rocket propelled grenades. The system can simultaneously engage several threats arriving from different directions, is effective on stationary or moving platforms, and is effective against both short- and long-range threats. Newer versions of the system include a reloading feature for multiple firings.

The iron fist mechanism is designed to be used with the Trophy active defense system. It senses incoming threats via a fixed active electronically scanned array radar sensor developed by RADA Electronic Industries and an optional passive infrared detector developed by Elbit's Elisra. When a threat is imminent, an explosive projectile interceptor is launched towards it. The interceptor explodes very near the threat, destroying or deflecting and destabilizing it without detonating its warhead. For this, only the blast effect of the explosive is used. The interceptor casing is made of combustible materials so no fragmentation is formed in the explosion, helping minimize collateral damage. On top of this are mortar radar detection systems, designed to detect and intercept oncoming mortar rounds and relay this information to the soldiers via the Net Warrior system, and the Boomerang anti-sniper device, which detects the direction of enemy sniper fire.

Aluminium oxynitride (AlON) is a transparent ceramic composed of aluminium, oxygen and nitrogen. It is marketed under the name ALON and described in U.S. Patent 4,520,116. It is 4 times harder than fused silica glass, and 85% as hard as sapphire. The material remains solid up to 1,200 °C (2,190 °F). When formed and polished as a window, the material currently (2005) costs about US$10 to US$15 per square inch (~ US$20,000/m²). The material is composed of three parts, an outer layer that's exposed to gunfire and made of baked aluminum oxynitride, a middle layer of glass, and a rear layer of polymer backing. The aluminum armor can deflect rounds from small-caliber weapons and still be more clearly transparent than bullet-resistant glass that's been shot, it also passes a much more important test -- it resists .50-caliber armor-piercing bullets and anti-aircraft weapons that typically use .30-caliber rounds, and is roughly half the weight and thickness of traditional ballistics glass.


Electronics
The System is operable with the Land warrior operating systems. In addition, it carries a GPS. The radio system is also compatible with the MARS system, and as well include a microwave and radar communications disk and radios. The vehicle charges the electronics of the soldiers, serving as a sort of mobile generator with the hybrid engine producing electricity for the men. The weapon systems of the vehicles are electronically controlled and remoted operated, generally by the CROWS II or Common Remotely Operated Weapon Station program, which not only protects the crew member by removing their need for exposure, but also allows them to operate a greater number of weapons without having to change position. Despite the plethora of weapon systems on the vehicle, only a certain number can be fired at any given point in time, based on which systems the weapons operator chooses. These weapons can also be operated by passengers in the vehicle, to free up operating control needed by the weapons operator.

As an intelligence counter measure, the vehicle sports a Boomerang Anti Sniper acoustic orientation device, intended on finding the location of incoming shots, using an array of speakers. This information is relayed directly to soldiers through the land warrior system, alerting them to the presence and location of enemy fire. With a very adept radar system, similar to the Longbow Apache radar, it can target multiple moving vehicles at once, and can intercept enemy vehicles, from aircraft to tanks, with missiles if necessary; this radar system is used to aim the AGM-114 hellfire missiles, and is useful in anti-aircraft targeting features to aid the 30mm in anti-aircraft attacks, as well as help locate enemy vehicles in general. Various FLIR thermal vision cameras are used to help locate enemy forces as well, and can be used to detect and automatically avoid missiles and incoming artillery. The same radar system can be combined with additional radar systems to serve as mortar and artillery battery radar,


Armament
The vehicle is capable of using a wide array of weaponry, as can be fit on the CROWS II, Defender, and ARROWS automated firing systems, and can utilize a multitude of other automated weapons systems. However, the vehicle predominately uses the following. The secondary weapon systems rotate on a single pivot, which is approximately 1,200 pounds.

The vehicle can be outfitted with either the 125mm Russian tank cannon, the 30mm 2A42 chaingun, or the 100mm SA70 cannon in addition to the 30mm chaingun. It also is designed to utilize a number of anti-tank and anti-air rockets, notably the 9M117 Bastion and 9M120 Ataka. 240mm mortar system. The 240mm Mortar system is an improved variant of the original system, increasing the range from 10,000 meters (6.25 miles) to 26,000 meters (16.25 miles), using an enhanced mortar round with more powerful propellant, and stronger materials to handle the higher pressures of the new round, as well as a base bleed mechanism to increase the range by an additional 30%. Utilizing a 312 pound projectile, it's slightly larger than the original 286 pounds, and delivers approximately 150 pounds of explosive to the target, with an additional 160 pounds of fragmentation. An autoloading mechanism allows it to load and fire rounds once every 20 seconds, approximately 3 times faster than the original, and a fire control system increases the accuracy, rate of fire, and targeting capabilities. The modernizaton efforts make it more accurate, and gives it a longer range, as well as speeding up the time to engage the target, being fired from the back of the vehicle rather than needing to be deployed from the ground and with an automated GPS and drone surveillance system allowing for more precise targeting. The 240mm mortar system was known for being extremely accurate and powerful, with an extremely long range, and the modernization effort has only improved this. There are three key variants, with the high explosive dual airbursting round (capable of both air bursting and ground explosion effects), the shaped charge variant, and the smoke rounds. The high-explosive dual air bursting variant etheir detonates with an impact fuze like a standard mortar, or can be preprogammed to air burst a certain distance above the target, using etheir a laser range finder to determine the air bursting distance, or a nose-laser to determine how far it is above the ground. Despite the large round and low rate of fire is extremely precise, which makes it's power extremely useful against lightly armored targets.
