The EC645 T2 is the latest 4-ton class twin-engine military helicopter inEurocopter’s product range, providing a multitude of deployment possibilitiesthat result from its power, range, endurance and payload capability.

Equipped with two powerful Turbomeca Arriel 2E engines – each controlledby a dual-channel full authority digital engine control (FADEC) – the EC645 T2retains excellent performance throughout the flight envelope, particularlywhen operating at altitudes of 6,000 ft and in 95 deg. F environments,commonly known as “6K/95 high and hot” conditions.

The EC645 T2 is based on the rugged construction, affordability and high mission reliability of Eurocopter’s proven EC145helicopter family – which is a reference worldwide. Its UH-72A Lakota version is in service for the U.S. Army, with morethan 250 delivered, boasting an availability rate of more than 90 percent.

A versatile multi-purpose armed helicopter,answering today’s growing demands andresponding to next-generation requirements

Enhancements to the EC645 T2 include an upgraded transmission system and incorporation of Eurocopter’s Fenestron tailrotor for improved anti-torque control. The latest technology glass cockpit and Helionix avionics suite – coupled with a highlycapable 4-axis digital autopilot system – ensure this helicopter accomplishes the job, no matter how demanding the mission.

The helicopter has a spacious unobstructed cabin, which is accessible through the side and rear doors, and can be fittedwith a wide selection of armament – ranging from ballistic to guided ammunition, providing outstanding flexibility for allforce operations from light utility to light attack.

It is perfectly suitable for primary missions:

Armed missions• Armed Scout• Special Operations• Light Attack

Additional configurations provideunique adaptability in a wide range ofcomplementary missions:

Utility mission• SAR• MEDEVAC/CASEVAC• Maritime• C3i: Command – Control –Communication – Information

The EC645 T2 can be easily and quickly converted, making it a true multi-role helicopter.

From Armed Scout to Light Attack missionsEquipped with an incremental modular incremental weapon system, the EC645 T2 can handle all types ofoperational scenarios, from conventional to asymmetric conflicts.

The optimized ratio of the cabin volume to the ground footprint, along with its low sound levels and thereduced infrared signature, makes the EC645 T2 a discreet and efficient Intelligence, Surveillance, TargetAcquisition, and Reconnaissance (ISTAR) platform.

The range of armament configurations,from ballistic to guided weapons,provides a flexible response for each situation. Coupled with a high-performance fire-control system,the aircraft can easily be reconfiguredinto a light attack platform.

Mission efficiency and flight safety areincreased with the new Helionix glasscockpit. Easy to operate, it contributesto reduced pilot workload and increasedsituational awareness, ensuring missionefficiency and flight safety.

With its open system architecture, the EC645 T2's incremental weapon systemcan carry:

• Two rigid multipurpose armamentpylons easily removable withelevation slaving units, 14-inchNATO slugs and jettisonablearmament

• Head-up Display (HUD)• Helmet Mounted Sight Display(HMSD) - with day and night pilotingand firing symbology

• An incremental electro opticalsystem (EOS) with day and nightcapabilities, fitted with infrared (IR),TV channels and adapted zoom, Laser range finder /designator / pointer

• An “open” and modular missioncomputer interconnected to the 4-axis autopilot, ensuringplatform stability and accuracywhen firing

• A wide choice of ballistic andguided weapon configurations

The EC645 T2’s long range and endurance, coupled with its large cabin space, enables the helicopterto transport up to 10 troops in a high-density air assault configuration, or a fully equipped team forspecial operations. The large sliding side doors and rear clamshell doors, along with the high-set main and tail rotors, offer360-degree approachability with the rotors turning, while providing unparalleled safety, access andspace utilization that facilitate troop access as well as the loading/unloading of armament and cargo.

Air assault & tactical transport

The outstanding balance between theEC645 T2’s weight and engine power,together with the capabilities of adoor-mounted gun, providesprotection during the extraction andinsertion of troops in threat conditionsand during Nap-of-the-Earth (NOE)flight profiles.

The door gunners’ positions with two7.62 mm machine guns provide arcsof almost 360° for suppressive fire.Alternatively one 12.7 mm sniper riflecan be fitted.

Special OperationsThanks to its multi-role capability,combined with its outstanding fast,agile and stealthy flight capabilities,the EC645 T2 is the ideal aircraft forspecial operations. These operationsinclude fast roping, rappelling anddirect air assault. The helicopter'ssmall footprint allows safe and easyaccess to confined areas.

The typical special operationsconfiguration accommodatesmachine guns and the internal cabin volume for a fully-equippedcombat team-ready to operate by day or night.

Utility – Tactical transport, Medevac/Casevac

As a true workhorse, the EC645 T2 excels in utility missions. Its large unobstructed cabin deliversunrivalled modularity, and its layout can be quickly converted to meet changing requirements with tworows of rails on the flat floor. The possibility to install seats, hoist, stretchers, medical equipment and cargo hook reinforces theEC645 T2's versatility.

11

The long flight endurance of the EC645 T2, associated with a new 4-axis autopilot, makes it an idealplatform for SAR operations. Furthermore, the day and night capability is complemented by a fullyautonomous navigation system.

Search and rescue

13

To enhance operations the aircraft includes:

• 4-axis digital autopilot withinnovative advanced modes

• Flight management system (FMS)with GPS and SAR modes

• TV / IR camera, eye-safe laserrange finder

• Four emergency floats as well asthe option of a raft

• Hoist system with 90-meter cableand 272 kg (600 lb) lift capacity,either on the right or the left side

• Search and weather radar• Single or dual stretcher capability• Searchlight with IR filter and laserpointer
