DASSAULT MIRAGE III

TYPE:
Single-seat fighter-bomber intruder aircraft.

DESIGN FEATURES:
Cantilever low-wing monoplane of delta planform, with
conical camber. Thickness/chord ratio 4 per cent to 3.4
per cent. Anhedral 1 degrees. No incidence. Sweepback
on leading-edge 60 degrees 34'. Tail unit has sweptback
fin.


STRUCTURE:
All-metal torsion box structure; stressed skin of
machined panels with integral stiffeners. The fuselage
is an all-metal structure, 'waisted' in accordance with
the area rule. Tail unit consists of fin and rudder
only.


LANDING GEAR:
Retractable tricycle type, with single wheel on each
unit. Hydraulic retraction, nosewheel rearward main
units inward. Messier-Hispano-Bugatti shock absorbers
and disc brakes. Mainwheel tyres size 750 x 230-15/1,
pressure 5.9-9.8 bars (85.5-142 lb/sq in). Nosewheel
tyre size 450 x 390-05. Braking parachute.

POWER PLANT:
One SNECMA Atar 9C turbojet engine (60.8 kN; 13,670 lb
st with afterburning), fitted with an overspeed system
which is engaged automatically from Mach 1.4 and
permits a thrust increase of approx 8 per cent in the
high supersonic speed range. Movable half-cone
centrebody in each air intake. Optional and
jettisonable SEPR 844 single-chamber rocket motor (14.7
kN; 3300 lb st) under engine bay. Space for structural
fuel tank, capacity 550 litres (145 US gallons; 121 Imp
gallons), when rocket motor is not fitted. Four
flexible fuel tanks around engine air inlet ducts,
combined capacity 1020 litres (269 US gallons; 224 Imp
gallons). Two integral fuel tanks in each wing combined
capacity 1370 litres (361 US gallons; 301 Imp gallons).
Total available internal fuel (without rocket motor)
2940 litres (775.8 US gallons; 646 Imp gallons).


ACCOMMODATION:
Single seat under rearward hinged canopy. Hispano built
Martin-Baker RM4 zero altitude/90 knots (267 km/h; 104
mph) ejection seat.


AVIONICS AND EQUIPMENT:
Duplicated UHF, Tacan, Doppler, CSF Cyrano II fire
control radar in nose, navigation computer and
automatic gunsight. Central gyro and other avionics
provide accurate and stabilised heading information.
CSF 97 sighting system gives air-to-air facility for
cannon and missiles, air-to-ground facility for dive
bombing or LABS, and navigation facility for horizon
and heading.


ARMAMENT:
Ground attack armament consists normally of two 30 mm
DEFA 552A guns in fuselage, each with 125 rounds of
incendiary, high explosive or armour-piercing
ammunition, and two 454 kg (1000 lb) bombs, or an AS-30
air-to-surface missile under the fuselage and 454 kg
(1000 lb) bombs under the wings. Total external load,
on five hardpoints 4000 kg (8818 lb). Alternative
underwing stores include combined tank/bomb carriers,
each with 500 litres (132 US gallons; 110 Imp gallons)
of fuel and 907 kg (2000 lb) of bombs; JL-100 pods,
each with 250 litres (66 US gallons; 55 Imp gallons) of
fuel and 18 rockets; jettisonable underwing fuel tanks.
For interception duties, one Matra R-530 air-to-air
missile can be carried under fuselage, with optional
guns and two Matra Magic missiles.
