1. INTRODUCTION
Introduction
The Mirage F1 is a single engine French fighter and attack aircraft first introduced in the early
1970s. It was envisioned originally as an all-weather interceptor and has seen many variants,
roles and configurations. It is still in service today with multiple air forces and private companies.
The F1 is equipped with a single SNECMA Atar 9K-50 afterburning turbojet, capable of delivering
70 kN of thrust at sea level. A Cyrano IV monopulse radar (later Cyrano IVM) is carried by most
of the variants of the aircraft.
The aircraft can carry an extensive variety of payloads: Both IR and radar air to air missiles,
guided and unguided bombs, rockets, as well as countermeasures, reconnaissance and
electronic warfare pods. Most versions also carry two internal 30 mm DEFA 553 cannons. Some
of the latest variants can carry the famous AM39 Exocet antiship missile.
History
During the 1960s, Dassault was involved in the development of several fighter design projects:
the F1, the larger F2, the swing-wing G and the BAC/Dassault AFVG. Cost and political issues led
to the cancellation of all of these projects, except of the F1, which was a lighter fighter aircraft
designed from the beginning to be the successor of the Mirage III and V families of aircraft.
The Mirage F1 wing and empennage configuration enabled it to improve upon some of the
problems of that the Mirage III and V suffered due to their delta wing configuration: The high lift
devices of the F1 allowed for shorter landing distances and better manoeuvrability and handling
at low speeds. The F1 was also able to carry 40% more fuel internally and had a more powerful
engine.
The initial prototype first flew on the 23rd of December of 1966, already achieving speeds in
excess of Mach 2 in its fourth flight. A fatal accident related to fluttering destroyed this
prototype but, after a redesign, the testing of the aircraft continued successfully and the first
deliveries of the production aircraft took place in May 1973.
The type has partaken in multiple conflicts serving different countries throughout its extensive
service life. With France it has served in Operations Manta, Epervier, Daguet (the Gulf War),
Provide Comfort, Harmatan and Serval over Chad, Libya, Mali, Kuwait… As well as in Afghanistan.
It partook in the South African Border War with South Africa, in the Paquisha War with Ecuador,
in the Libyan civil war, in the Western Sahara War with Morocco and, perhaps most famously,
in the Iran-Iraq and Gulf wars with Iraq.
The Mirage F1 has served in the air forces of several countries: France, Iraq, Spain, South Africa,
Greece, Jordan, Kuwait, Ecuador and Qatar. It is still in operation in several others: Morocco,
Iran, Libya, Gabon and the Republic of the Congo. It also serves in private aggressor training
services in the USA.

Main variants
More than 700 units of the Mirage F1 have been produced and it has been exported to several
countries. The different necessities of customers over the years have led to the emergence of
multiple variants to better satisfy specific requirements:
Mirage F1-C: The original all-weather interceptor variant for the ‘Armée de l’Air’,
exported to several countries (Spain, Greece, Morocco…). Several of these aircraft were
reconverted to the CT (close air support) specification for France. The C-200 was a C
version with air refuelling capability, also for the ‘Armée de l’Air’. Despite its main role
as an interceptor, a secondary role as ground attacker was considered, and a wide
selection of air-to-ground ordnance was also available for these models.
Mirage F1-B: Two seat conversion trainer of the Mirage F1-C. It was capable of carrying
the same ordnance as the Mirage F1-C but the extra seat came at the cost of less fuel,
a slight increase in weight and the loss of the internal cannons. External cannon pods
could be mounted instead.
Mirage F1-E: Multirole and ground attack version of the Mirage F1-C, it was equipped
with a better navigation suite and air refuelling capability. All of the E versions made
were for export clients (Iraq, Spain, Jordan, Ecuador…). Of special note are the later
Iraqi versions, which were equipped with a wide variety of guided air to ground
weapons.
Mirage F1-D: Two seat version of the F1-E. Only 2 were built, both for Qatar.
Mirage F1-A: Simplified ground attack variant for the South African Air Force and the
Libyan Air Force. It substituted the Cyrano IV radar with a laser rangefinder.
Mirage F1-CR: Dedicated reconnaissance version which included visual and IR cameras
(the IR camera replaces one of the cannons), a radar with extra ground mapping
capabilities and a variety of pods, including ELINT and side looking radar. It served with
the ‘Armée de l’Air’ and some were later sold to an aggressor company in the USA.
Mirage F1-M: Spanish modernised version based on the Spanish C and E models carried
out by Thomson-CSF. The modernisation vastly improved air to ground capability,
included the new Cyrano IVM radar with sea search modes, as well as new navigation
suites, a colour LCD and new HUD.
The Mirage F1-CE
The Mirage F1-CE is the export variant for Spain of the interceptor French F1-C, it entered service
in 1975, making the ‘Ejército del Aire’ the second client to buy the type. It differs slightly from
the French version in its ability to carry American made AIM-9 Sidewinder missiles, as well as
having an incorporated countermeasure suite. Most of their operative life was spent in the ‘Ala
14’, based in Los Llanos Air Force Base, until the year 2000, in which it was completely replaced
by the F1-M.

3.2 ELECTRICAL SYSTEM
Description
The electrical system consists of:
-Two 15 kVA three phase alternators at 400 Hz and 115/200 V AC
-Two 100 A transformers-rectifiers (TR)
-One 40 Ah battery.
-A static inverter
-A switching box that enables to supply an emergency AC system by the alternators or
the DC system through the static inverter.
-A standby receptacle that enables certain equipment to be energized and preheated on
the ground.
-An external AC power receptacle to supply the systems from an auxiliary power unit.
The electrical power is distributed by:
-AC system 1, normally supplied by alternator 1
-AC system 2, normally supplied by alternator 2
-Emergency AC system, normally supplied by alternator 1
-DC system, normally supplied by the TR’s and the battery. It comprises:
oa direct battery system
oa main system
oa utility subsystem, with automatic shedding in case of both alternators failure.
There are three missile busses, shedding occurs if an alternator fails and RPM are < 5600.
See limitations chapter regarding alternators ventilation.
Operation
When there is undervoltage detection in AC system 1, the emergency AC system is switched to
the inverter. The EMG~ light is on.
When the standby receptacle is connected, the batteryand the distribution systems are isolated.
During start, the cranking and ignition of the engine are electrically accomplished on the battery.
After starting, the alternators cut in when they reach their frequency and voltage thresholds,
this happens at approximately 2800 engine RPM.
The inverter selector is set to RESET, switching the emergency AC system to system 1. The EMG~
light goes out.
As soon as the alternators cut in, the standby receptacle disconnects and the aircraft is supplied
normally.
When the external power receptacle is connected, the alternators are isolated (battery switch
ON, light is out) and the two AC systems are supplied.
The external power has priority over the alternators.
There is no external DC power receptacle, since the aircraft is equipped with transformer-
rectifiers.

and AUTO) and a RESET spring-loaded position.
Failure lights
-Red BATT light: the battery is disconnected from the main system.
-Amber ALT 1 light: the alternator 1 is not supplying its system.
-Amber ALT 2 light: the alternator 1 is not supplying its system.
-Amber TR1 light: the transformer-rectifier 1 is not supplying the DC systems.
-Amber TR2 light: the transformer-rectifier 2 is not supplying the DC systems.
-Amber SEC  light: emergency AC system supplied by the inverter.
-Red MODUL light: excessive modulations of the vario-alternator driving torque.
