Griffin is an air and ground launched precision guided missile which enables the AT-6 to lock targets through a simple graphic user interface.
Griffin Missile System
The Griffin® missile is a multi-platform, multi-service weapon that has a proven track record for successful rapid integration on land, sea and air platforms.
It is available in two variants: Griffin A, which is an aft-eject missile and Griffin B, which is a forward-firing missile. Raytheon continues to evaluate additional upgrades to Griffin that enables the warfighter.
The Griffin missile provides the user with flexible employment options through a simple, easy-to-operate, graphical user interface. The user can select from multiple flight profile and fuzing modes. It also provides lethal effects and employs GPS-aided inertial guidance and a semi-active laser seeker for pinpoint accuracy.
Griffin variants include:
GRIFFIN A MISSILE
- An aft-eject missile from a common launch tube
- Deployed from platforms like the C-130 aircraft
- Measures 43 inches long, weighs 34 pounds and has a low collateral damage 13-pound warhead
- Production began in 2008
GRIFFIN B MISSILE
- A forward-firing missile that uses a composite launch tube
- Launches from rotary- and fixed-wing aircraft, ground-launch applications and maritime platforms
- Operational on the U.S. Navy’s Cyclone-class Patrol Coastal ships
- Measures 43 inches long, weighs 34 pounds and has a low collateral damage 13-pound warhead

Self-protection systems and armour
The AT-6 is fitted with cockpit and engine armour for increased aircraft protection.
An infra-red countermeasures suite can include the AN/AAR-47 missile approach warning system and ALE-47 countermeasures dispenser system.
AN/AAR-47 missile approach warning system
The AN/AAR-47 is an electronic warfare system designed to protect aircraft against IR guided missile threats, laser-guided / laser-aided threats and unguided munitions. Upon detection of the threat, the system will provide an audio and visual sector warning to the pilot. For IR missile threats, the system automatically initiates countermeasures by sending a command signal to the Countermeasures Dispensing Set.
Multi-Threat Detection: Missile, Laser, and Hostile Fire
Orbital ATK’s AN/AAR-47 System Offers:
• Multi-threat warning in one fully integrated system

ALE-47 countermeasures dispenser system
In response to automated warnings of radar, infrared, laser and other threats against aircraft, the AN/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.
These expendables include radar-reflecting chaff, infrared countermeasures to confuse heat-seeking missile guidance, and disposable radar transmitters. In addition to active and passive countermeasures, expendables now include sensors for both electronic support, electronic warfare, and other intelligence functions such as chemical weapon detection using materials MASINT. In addition to the truly expendable items usually released as cartridges, a modern dispenser system will control towed decoys that lure radar- and infrared-guided missiles that avoid the other countermeasures.

Engine and performance of Hawker Beechcraft’s aircraft
The aircraft uses a Pratt & Whitney Canada PT6A-68 turboprop engine which provides a flat rated 1,100hp (820kW).
Pratt & Whitney Canada PT6A-68 turboprop engine
The PT6A engine family continues to advance, incorporating the latest technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. More than 70 PT6A models have been produced, ranging in shaft horsepower power from 500 shp to 2,000 shp. New aerodynamic and material technologies have enabled the PT6 engine to gain more power without significantly increasing in size. Other innovations have reduced emissions, increased maintenance intervals and further enhanced ease of operation with the introduction of digital electronic control to small gas turbine engines.
The novel PT6A configuration has proven a key attribute to its success: its rearward, reverse flow inlet and forward facing turbine section providing fast maintenance turn-around through on-wing hot section refurbishment in most aircraft installations. The PT6A is a two-shaft engine with a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the propeller through an epicyclic concentric reduction gearbox.
The PT6A family of engines embodies three series of models with increasing power levels, referred to as PT6A ‘Small’, ‘Medium’ and ‘Large.’ The increased power levels are achieved through the increase of compressor air flow and increased number of power turbine stages. Most recent models enjoy the advantage of additional advanced technologies in materials, turbine cooling and aerodynamic design.
