The Bell AH-1Z Viper is a modern version of the first ever attack helicopter, the AH-1 Cobra. It is also called Zulu Cobra in reference to its variant letter. Since its introduction in the mid 1960s the original Cobra has been constantly improved and upgraded. The latest AH-1Z Viper is a result of H-1 helicopter upgrade program for the US Marine Corps. It was launched by the US Government in 1996 and has been won the Bell helicopter company. It is worth noting that the Viper was developed alongside the UH-1Y Venom transport helicopter under the same program.
The UH-1Y Venom was developed from the previous UH-1N Twin Huey, introduced in the early 1970s. Extremely successful, versatile and reliable airframe of the UH-1 was integrated with modern avionics and new propulsion. It uses a lot of off-the-shelf technology. It has a high degree of commonality with the AH-1Z Viper, which was developed under the same program. Even though these air vehicles serve to totally different missions. Viper is premier attack helicopter while Venom is utility transport chopper. However they share 85% of replaceable components. These helicopters share engines, rotor system, transmission, tail boom, avionics, controls and displays and other components. Such commonality allowed to reduce production, maintenance and overall operational costs.
This helicopter can carry 8 fully equipped soldiers. Its modular construction permits cargo bay to be transformed for other roles, such as MEDEVAC and cargo carrying.
The Venom helicopter can be armed with 12.7-mm or 7.62-mm machine guns, or 7.62-mm Gatling guns installed in the open doors on either side of the fuselage. Also it can carry pods with Hydra 70 unoperated rockets or APKWS laser guided anti-armor missiles. These are used for self-defense to soften-up enemy defenses before landing.
On combat missions USMC typically deploy 2-4 utility helicopters alongside with detachment of 4-8 attack helicopters.

The AH-1Z Viper is a direct derivative of the AH-1W Super Cobra. It is one of the most powerful, capable and advanced helicopters, flying today. The AH-1Z made its first flight back in 2000. It was introduced to the US Marine Corps in 2010. Full scale production commenced in 2012. Marines plan to receive a total of 189 Vipers until 2019. These include 131 AH-1W upgraded into AH-1Z and 58 newly built AH-1Z helicopters. In 2015 it was announced that 12 of these gunships will be delivered to Pakistan.
AH-1W Super Cobra
AH-1W Super Cobra attack helicopter was developed by Bell for the US Marine Corps (USMC). It evolved form the AH-1T and follows the general outlines of the AH-1 Cobra. The Super Cobra was adopted by the USMC in 1986 and is still in service. This gunship was used during the Persian Gulf War. A total of 48 AH-1W attack helicopters were used during that war. These gunships destroyed 97 tanks, 104 armored personnel carriers, 16 bunkers and 2 anti-aircraft sites. Not a single USMC helicopter was lost during that war.
The main role of this attack helicopter is to provide close in fire support for landing forces during amphibious assaults and subsequent land operations. It also escorts transport helicopters with troops.
The Super Cobra has a slim fuselage with a fighter-type cockpit. The pilot sits high in the rear with a co-pilot/gunner lower in the front directing the fire of a wide range of weapons mounted on lateral stub wings or under the nose. The front seat also has a full set of flight controls. The cockpit is surrounded by armor protection.
The AH-1W Super Cobra can fly and provide fire support in both day and night environment. Its avionics, engines and weapons were substantially upgraded comparing with the previous version. It is fitted with a night targeting system, which includes a Forward-Looking Infra-Red (FLIR), low-light TV camera, laser rangefinder and an autotrack system.

Bell Helicopter announces half-billion dollar contract: Here
The Z-model’s integrated avionics system (IAS) has been developed by Northrop Grumman. The system includes two mission computers and an automatic flight control system. Each crew station has two 8×6-inch multifunction liquid crystal displays (LCD) and one 4.2×4.2-inch dual function LCD display. The communications suite combines a US Navy RT-1824 integrated radio, UHF/VHF, COMSEC and modem in a single unit. The navigation suite includes an embedded GPS inertial navigation system (EGI), a digital map system and Meggitt’s low-airspeed air data subsystem, which allows weapons delivery when hovering.
The crew are equipped with the Thales “Top Owl” helmet-mounted sight and display system. The Top Owl has a 24-hour day/night capability and a binocular display with a 40° field of view. Its visor projection provides forward looking infrared (FLIR) or video imagery. The AH-1Z has survivability equipment including the Hover Infrared Suppression System (HIRSS) to cover engine exhausts, countermeasure dispensers, radar warning, incoming/on-way missile warning, and on-fuselage laser spot warning systems.
The Lockheed Martin Target Sight System (TSS) incorporates a third-generation FLIR sensor. The TSS provides target sighting in day, night, or adverse weather conditions. The system has various view modes and can track with FLIR or by TV. The same system is also used on the KC-130J Harvest HAWK. Source wikiwand.com
Upgrades of the AH-1Z included implementation of state-of-the-art weapons and digital technology to respond to modern demands for contemporary warfare. The Viper features outstanding flying and combat capabilities.
2 x General Electric T700-GE-401C turboshaft engines
The T700 engine was designed for the US Army’s UH-60A Black Hawk helicopter as a result of lessons learned in Vietnam. The key requirements of this engine were reliability, operation under adverse environmental conditions and low maintainability.
The T700-GE-401 engine was the first engine qualified, under US Navy’s rigorous salt ingestion tests, suitable for shipboard operations. This engine was selected to power AH-1Z/W and UH-1Y among other naval helicopters.
Diameter: 400 millimeter (15.7 inch)
Length: 1,170 millimeter (46 inch)
Max Power at TakeOff: 1,723 shp (1,285 kW)
Dry Weight: 200 kilogram (441 pound)
The AH-1Z has essential changes in propulsion. It is powered by two General Electric T700-GE-401C turboshaft engines and has uprated transmission. One of the main external differenced from the AH-1W is a composite 4-bladed main rotor, instead of the previous 2-bladed rotor. It reduced vibrations by up to 70 percent. It is worth noting that a 2-bladed rotor was a distinctive feature of all previous Bell helicopter models. However due to these changes flying characteristics improved a lot.

Despite all improvements and upgrades appearance of the AH-1Z remains the same. Pilot is seated at the rear and co-pilot/gunner at the front. Layout of two integrated digital cockpits is identical and all systems are duplicated.
This helicopter uses off-the-shelf electronic systems. It can operate in day, night, or adverse weather conditions. It has night vision twinned with infrared and new target search and acquisition software. It permits Viper to find and engage targets at long range. It can be fitted with Longbow fire control radar, mounted on wingtip station. Also there is automatic flight control station.
The AN/APG-78 Longbow fire control radar can also be mounted on a wing tip station
The LONGBOW FCR has a very low probability of intercept. It rapidly and automatically searches, detects, locates, classifies, and prioritizes multiple moving and stationary targets on land, water and in the air in all weather and battlefield conditions from standoff ranges. Target coordinates are automatically available to other sensors and weapons for target confirmation, rapid engagement, and reduced fratricide. Target data is digitally available through the data modem for real-time transfer to other platforms and command posts. The self-contained Radar Frequency Interferometer provides rapid and accurate identification and azimuth to enemy air defense units. High system reliability and two-level maintenance maximize operational availability and reduce support costs. Source lockheedmartin.com

AN/AAR-47 Missile Warning System
The AN/AAR-47 Missile Warning System is aMissile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft’scountermeasures systems. Its main users are theU.S Army, Navy and Air Force, but is also operated by other countries. Originally developed by Loral (now part of BAE Systems), it has been solely a product of Alliant Techsystems(ATK) since 2002.
The AN/AAR-47 passively detects missiles by theirUltraviolet signature, and uses algorithms to differentiate between incoming missiles and false alarms. Newer versions also have laser warning sensors and are capable of detecting a wider range of threats. After processing the nature of the threat, the system gives the pilot an audio and visual warning, and indicates the direction of the incoming threat. It also sends a signal to the aircraft’s infrared countermeasures system, which can then for example deploy flares.
The AAR-47 missile warning system consists of 4 Optical Sensor Converters (OSC), a Computer Processor and a Control Indicator. The system is relatively light at a total weight of approximately 32 pounds.
There is one optical sensor converter for each side of the aircraft. They have an infrared camera for detecting incoming missiles. The Optical modules since version AAR-47(V)2 include a laser warning sensor, and versions since AAR-47A(V)2 further incorporate an ultraviolet sensor for improved dynamic blanking laser warning detection.
The computer processor evaluates the data from the OSC:s and analyzes whether a detected event is an incoming missile. If a threat is detected, it sends a signal to the control indicator which informs the crew, and the aircraft’s infrared countermeasures system. Source revolvy.com
AN/AVR-2A Laser Warning System
The AN/AVR-2A is a passive laser warning system which receives, processes and displays threat information resulting from aircraft illumination by laser designators, range finders and beam riding missiles. The threat information is displayed on the AN/APR-39A(V)1 Radar Detecting Set indicator in the cockpit. The AN/AVR-2A LDS is derived from the basic AN/AVR-2 LDS through the incorporation of several engineering change proposals (ECPs). These ECPs include: incorporation of the Multiple Integrated Laser Engagement System-Air-to-Ground Engagement System interface; incorporation of a removable user data module to the comparator interface to permit a means to apply software changes and system declassification; and increased Band III sensitivity for improved threat detection performance. The AN/AVR-2A LDS consists of one interface unit comparator and four identical sensor units. The total system weight is 21 pounds.
The AN/AVS-2B(V) was derived from the system developed for the Sikorsky RAH-66 Comanche. Goodrich claimes it is 40% smaller, 45% lighter (i.e. approx. 2,5 pounds (1,5 kg) per sensor) and uses 45% less power than the previous AN/AVR-2A(V) version . The system provides increased functionality for threat detection and data interface and has demonstrated a 500% improvement in reliability. The model was introduced into service in 2004.

BAE Systems AN/ALE-47 Airborne Countermeasures Dispenser System
In response to automated warnings of radar, infrared, laser and other threats against aircraft, theAN/ALE-47 Countermeasures Dispenser System (CMDS) both assists the crew in staying aware of the threats, and managing the deployment of electronic warfare devices that operate externally to the vehicle. “Electronic”, in this context, covers enemy sensors across the electromagnetic spectrum. Electronic defense includes, as well as receivers and computers that detect and analyze threats, both countermeasures that are part of the aircraft, but also expendables that are released from it.
In other words, it both acts as an electronics countermeasures suite controller and as an electronic warfare expendables dispenser. It replaces the AN/ALE-39. Alternatively, it can be controlled by other control systems, such as the AN/ALQ-213. Source citizendium.org
Armament of the Viper is very flexible. It is enhanced by helmet-mounted sight and display system. The AH-1Z carries about 2 t of various weapons on stub-wings. Typically it carries AGM-114A/B/C Hellfire anti-tank missiles (up to 16) and pods with 70-mm unguided rockets. The Viper can be also fitted with AGM-114F Hellfire anti-ship missiles, free-fall bombs, including the Mk.77 incendiary bombs. It can also carry two fire-and-forget AIM-9 Sidewinder supersonic air-to-air missiles with infrared target detection. These a mounted on wing tip stations. Also there is a 20-mm three-barrel cannon.
Main Gun: 1x General Dynamics M197 20mm three-barreled gatling gun with 750 rounds (in A/A49E-7 turret).

The M-197 produced by General Dynamics Ordnance and Tactical Systems is a lightweight, three-barrel version of the M61A1 Gatling gun intended for applications that require a lightweight, highly reliable weapon capable of firing up to 1,500 shots per minute.
The gun is specifically designed for helicopters, light fixed-wing aircraft and small naval attack vessels. It is adaptable for turret, pod, pintle or internal installations using either linked or linkless ammunition feed systems. Currently, the M-197 arms the Marine Corps AH-1J, AH-1T, AH-1W and AH-1Z. The M-197 is also used in the GPU-2/A 20mm gun pod.
Power requirements for the M-197 are lower than most weapons offering comparable rates of fire due to the M-197’s continuous rotary motion. The M-197 is also capable of firing longer burst lengths than its competitors.

AIM-9M Sidewinder missile
The Lima was followed in production in 1982 by the AIM-9M, which is essentially an improved AIM-9L. The Mike has improved background rejection, counter-countermeasures capability and a low smoke motor to reduce the visual signature of the inbound weapon. The AIM-9M has the all-aspect capability of the AIM-9L model, but provides all-around higher performance. The M model has infra-red countermeasures, enhanced background discrimination capability, and a reduced-smoke rocket motor. Deliveries of the initial AIM-9M-1 began in 1982. The only changes from the AIM-9L to the AIM-9M were related to the Raytheon Guidance Control Section (GCS). Several models were introduced in pairs with even numbers designating US Navy versions and odd for US Air Force. All AIM-9M GCS are comprised of three major assemblies; a seeker assembly for detecting and tracking the target; an electronics assembly for processing detected target information; and a servo assembly that transforms electrical tracking signals to mechanical movement of the fins. An umbilical cable assembly provides electrical interface between the missile GCS and the aircraft launcher. The umbilical I-3 cable also allows the flow of coolant from the LAU-7 to the missile GCS. AIM-9M GCS versions include the WGU-4A/B used in the AIM-9M-1 and AIM-9M-3, the WGU-4C/B used in the AIM-9M-4, the WGU-4D/B used in the AIM-9M-6, and the WGU-4E/B GCS used in the AIM-9M-8. The WGU-4E/B GCS uses advanced technology that has evolved through the WGU-4D/B development, while expanding the potential of the IRCM detection circuitry and improving the missile’s capability with respect to tactical IRCM deployment.
