A contract was awarded in April 1996 to
supply 67 AH Mk1 Apache aircraft to the MoD
for use by the British Army. The AH Mk1 is a
dedicated attack helicopter based on the
AH-64D which benefits from investment in its
configuration as a Longbow standard aircraft with
the addition of UK specific mission equipment for
enhanced self-defence and all-weather capability.
Westland is the UK Apache Prime
Contractor and co-ordinating Design Authority
and its main responsibilities include the following:
s Overall Prime Contractor
s Delivery of 67 aircraft between
2000-2004
s Last aircraft delivered in Q2 2004
s
Integration of RTM322 engine andUK Defensive Aids
s Aircrew training, infrastructure
and facilities
s Procurement of major sub-assemblies,
systems and equipments
s Manufacture of dynamic components,
aircraft assembly, test and delivery
The AH Mk1 Team was formed in order to
offer Apache to the MoD to meet their
requirement for an off-the-shelf, reliable, high
performance attack helicopter. Westland
teamed with Boeing, Lockheed Martin and
Longbow International and the choice of
Apache capitalises on nine years of the United
States’s investment in upgrading the A models
of Apache to the D version.

High supportability is a design
requirement for the Apache. Ease of access to
components, simplified diagnostics and repair
procedures and reduced ground support
equipment results from a MANPRINT
approach. The AH Mk1 Apache is based on the
experience of the US Army Apache which has
over 1,000,000 flying hours in war and peace.
High maintainability and reliability have
been achieved by planned upgrades
which are evident in availability rates
for deployed operations of over 90%
in Apache fleets across the world.

E F F E C T I V E N E S S
AH Mk1 Apache is the only attack helicopter
that has the system capability and payload to
execute all designated roles concurrently, giving a
Force Commander complete flexibility. Apache
has been shown to be the most operationally
effective attack helicopter.
GENERAL CONFLICTS
AH Mk1 Apache can destroy enemy targets
at long ranges reducing losses of both troops and
equipment to a minimum.
OPERATIONS OTHER THAN CONFLICTS
AH Mk1 Apache is equally effective in
operations short of war or peace-keeping
operations, characterised by political sensitivity
and the close proximity of combatants to the
civil population.
CRISIS RESPONSE
AH Mk1 Apache, with its multi-weapon
payload, 1,400 km ferry range and over 450 km
operational radius of action can quick ly deploy
from out of theatre to a potential flash point
to deter aggression. Apache can form an
over-the-horizon force of great flexibility and
potency whose excellent surveillance and
stand-off range can avoid direct confrontation
and enhance its survivability.
Michael Portillo MP
Secretary of State for
Defence
House of Commons
13th July 1995
“Apache will provide the British Army with a
world-class capability and offer the right combination
of mobility, rapid deployment, reach and fire-power.
Those who risk their lives for this country will be
provided with the helicopter that we believe can
destroy the highest number of enemy targets with
the least loss of life among crews.”

MULTI- ROLE PAYLOAD
10,000 lb Payload.
4 multi-purpose wing stations,
together with 2 wing-tip AAM
stations and the nose mounted
30mm gun, confer a concurrent
multi-role capability which allows an
immediate response to anysitua-
tion. Role changes are eliminated
with a load of 8 Hellfire, 38 70 mm
rockets, 1200 rounds of 30mm
and 4 AAM.
FIRE CONTROL RADAR
The Longbow mast mounted Fire
Control Radar (FCR) rapidly
detects, classifies, prioritises and
engages ground and air targets
in adverse weather, dust, smoke
and battlefield obscurants. This
unique system enables engage-
ments to be made outside threat
response range and inside threat
response times, significantly in-
creasing survivability. An integrated
Radio Frequency Interferometer
passivelygives identification of, and
precise bearing to, thr eat emitters
at verylong range.
MANPRINT COCKPIT
The highlyintegrated MANPRINT
cockpit, employing coloured Multi
Function Displays, provides en-
hanced situational awareness and
battle management to enable the
crew to fight t he aircraft effectively
in high threat situations. Full
redundancyis provided to enhance
flexibilityan d survivability.
COMMUNICATIONS
Apache provides the potential
for battlefield command/ attack
co-ordination through real-time
Joint/ All Arms Data sharing,
multimedia intelligence exchange
(including video) and an integrated
data modem.
AIR-TO-AIR MISSILES
4 Air-to-Air Missiles (AAM) maybe
carried on the wing tip stations.
DEFENSIVE AIDS SYSTEM
The BAESYSTEMS compr ehensive
Helicopter Integrated Defensive
Aids Suite (HIDAS) includes radar,
laser warnings and chaff and flare
dispenser.
ENGINES
Twin Rolls-Royce RTM 322 engines
provide the power and response
for worldwide operations. Inlet
particle separators protect the
engines in dust and sand and full
IR suppression guarantees a very
low IR signature.
BATTLE DAMAGE
TOLERANCE AND
CRASHWORTHINESS
Apache is fully protected against
12.7mm rounds and is highly
tolerant of 23mm HEI rounds,
ensuring a high probability of
mission success and crew survival.
Crashworthyseats, structure and
undercarriage, together with a wire
strike protection system, provide
further crew protection.
TARGET ACQUISI TION
AND DESIGNATION
Selectable FLIR, TV or direct view
optics in the stabilised Target
Acquisition and Designation Sight
enable targets to be acquired and
laser designated night and day. The
TADS is fully integrated with the
FCR for rapid target identification
with magnification up to 127 times.
PILOT NIGHT VISION
The Pilot Night Vision Sensor
(PNVS) and Integrated Helmet And
Display Sighting System (IHADSS)
provide a visuallycoupled, night and
adverse weather piloting system.
Flying and weapon aiming informa-
tion is presented “head-up” to the
pilot and the FCR terrain picture
may also be selected on the helmet
mounted display.
30MM GUN
30mm gun carries 1200 rounds
for rapid off-axis engagement of
both ground and air targets. The
turreted mounting enables the gun
to be used whilst continuing with the
primaryanti-armour engagement.
MAIN ROTOR
The four bladed low signature main
rotor provides high agility (including
negative ‘g’) and high levels of
tolerance of 23mm HEIrounds and
wire and tree strikes. Full main and
tail rotor deicing helps to provide a
24 hour worldwide capability.
ROCKETS
Up to 76 CRV7 70mm multi-
purpose rockets may be carried
for the engagement of area targets.
These rockets are effective against
light armour, soft skinned vehicles
and personnel.
NAVIGATION
The precision, all weather naviga-
tion system employs a Kalman filter
with GPS, inertial, doppler and air
data sensing to keep the crew con-
stantlyinformed of t heir location.
HELLFIRE MISS ILES
Apache carries up to 16 Laser
and fire-and-forget Radio Frequency
guided long range Hellfire missiles
for the precision engagement of
selected point targets under all
weather conditions. The dual war-
head defeats all known tank armour.
SUPPORTABILITY
Apache is designed for ease of
maintenance in the field with
built-in steps and working platforms,
ease of access, built-in test equip-
ment (for 90% of faults at 1st line),
simpler diagnostics and repair pro-
cedures (only10 tools required).
TRANSMISSION
The rugged main rotor gearbox
is designed for rapid removal
without removing the rotors and
rotor mast. A 30 minute ‘run-dry’
capabi li ty contributes to high
survivability.
UNDERCARRIAGE
The crashworthy, wheeled under-
carriage provides rapid ground and
ship mobility.
FUEL SYSTEM
2400 lbs of internal fuel enables
over 2 hours primary mission
endurance. Up to 4 long range
external tanks may be easily fitted
to increase combat radius/ time on
patrol or enable self deployment up
to 1500 km range.
TAIL ROTOR
Four bladed low signature tail rotor
provides powerful and precise yaw
control for agility, weapon aiming
and 45 knot cross-wind capability.
The tail rotor is located so as to
prevent ground strikes and mini-
mise hazards to personnel.
