This entry is for the Interdictitor/Strike version. Information about the Air Defence version can be found on the Fighter Aircraft Wiki.
On 26 March 1969. Panavia was formed to handle the MRCA (Multi-Role Combat Aircraft) contract from the involved governments (UK, Germany, Italy and the Netherlands), originally comprising BAC, MBB, Fiat (later Aeritalia) and Fokker-VFW, with the Netherlands withdrawing that July (now BAe, Daimler-Benz and Alenia). The project definition phase began in May, leading to the formation on 1 June of Turbo Union Ltd, who were tasked with the design, development and production of the MRCA engine.
The Pre-development phase began in July 1970, followed in September 1971 by the involved governments declaring their Intention To Proceed (ITP) declared by the involved governments, and the first ground test run of the RB199 engine at Bristol, which took place on 27 September. In August 1972, the full development contract was awarded, with a decision about production investment following in March 1973.
- Crew: Pilot and navigator in tandem.
- Cockpit: Front screen in 3 panels, and hinges forward for maintenance access. Single-piece clamshell canopy, hinged at rear. "Two stick" trainer variant retains operational capability.
- Crew escape: Martin Baker Mk 10A fully automatic ejection seats, zero-zero to 625 kts CAS/Mach 2 and 50,000 ft (15,240 m). Canopy jettison prior to ejection, but MDC assists egress in unlikely case of jettison failure.
- Fixed guns: 2 x 27-mm Mauser cannon, in the sides of the lower fuselage. Selectable high and low rate of fire. No guns in the GR Mk 1A reconnaissance version or ECR.
- Ammunition: 180 rounds per gun.
- Number of weapon pylons: 7. Flat fuselage underside is suited to the carriage of long-range weapons, and has 3 "wet" stations (centreline and 2 outer). Dependent on the stores carried, all 3 may be used simultaneously. Each moving wing panel has inner and outer swivelling pylons; inner are "wet" and outer dedicated to ECM and chaff/flare pods. Twin or triple stores carriers can be fitted. Inner wing pylons have adapters for Sidewinders in addition to the main store.
- Expendable weapons and equipment: Maximum payload of about 19,842 lb (9,000 kg) for both IDS and ECR. Extremely wide range of weapons, including all standard high-explosive bombs, cluster bombs, retarded and low—drag bombs, and laser-guided bombs; programme currently unden/vay in 1995 to integrate Paveway lll low-level LGB. WE177B tactical nuclear weapon used by RAF (until 1998). Practice bomb carriers. Alternative weapons include rocket pods, large weapon dispensers including JP233 and MW-1 for airfield attack and Matra Apache for stand-off attack, and various air-to-surface missiles including Maverick, anti-ship Kormoran and Sea Eagle, and ALARM and HARM for anti-radar. Future weapons will include the US JSOW. Sidewinders provide self defence. Typical configurations are: 8 x 1,000 lb bombs plus 2 Sidewinders, 2 ECM pods and 2 drop tanks; 2 JP-233 dispensers, 2 Sidewinders, 2 ECM pods and 2 tanks; 4 HARM missiles and 2 ECM pods; 2 Kormoran or Sea Eagle missiles and 2 tanks; MW-1, 2 AIM-9L Sidewinders, ECM pod, chaff/flare dispenser and 2 tanks; and 7 ALARM missiles, ECM pod, chaff/flare dispenser and 2 tanks.
- Additional stores: Reconnaissance pod on centreline, equipped with wide-angle cameras and infra-red linescan, developed by MBB for German service; new pods being delivered for the Luftwaffe (see Aircraft variants). Buddy-buddy refuelling pod available on centreline. Thermal Imaging and Airborne Laser Designator (TIALD) pod. RSAF lDSs have Thomson-CSF designator pod.
- Radar: Ground Mapping Radar (GMR) for blind navigation and targeting, and Terrain Following Radar (TFR) with auto-terrain following capability. Signals from the high resolution mapping radar and TF radar are processed in a shared LRU. Doppler radar for navigational use.
- Flight/weapon system avionics/instrumentation: Principal to the avionics system is a 256 kilobyte Litef Spirit 3 digital main computer (being replaced on German and Italian lDSs by an 8 megabyte computer with Ada software), which handles the navigation, flight direction and terrain following, weapon aiming and delivery, computing, communications and defensive aids sub-systems. The sub-systems are interlinked with the GMR and TRF (see Radar), autopilot and flight director system (AFDS), digital inertial navigation system (INS), Tacan, Doppler radar, secondary altitude and heading reference system (SAHRS), air data computer, laser ranger/marked target seeker (LRMTS), ECM/ECCM, communications transmitters and receivers, lFF and lLS. Later production aircraft were also given MIL-STD-1553B (see German MLU under Aircraft variants) databus architecture, enlarged main computer memory, digital missile control unit, advanced displays, new stores management system, a solid state mission data transfer system, improved radar warning system and active ECM. On-board check-out and monitoring system (OCAMS). German ECR is equipped with FLIR, which will be introduced on the RAF's GR Mk 4 variant. Pilot's displays are HUD, head-down moving map, terrain-following E-scope and radar threat warning. Navigator's displays are centrally-located combined mapping radar and moving map display, with identical CRT display either side for navigation and mission planning. May also be used to display electro-optic sensor data (such as FLIR). "Two stick" trainer variants have port CRT display removed and flight instruments installed in the rear cockpit. See Mid-Life Updates under Aircraft variants.
- Self-protection systems: Threat radar warning receivers are incorporated, forward and rearward antennae of which are mounted high on the fin leading and trailing edges. A mix of active ECM pods and chaff/flare pods is normal. RAF aircraft usually carry Sky Shadow ECM pod on the port outer wing pylon and BOZ-100 chaff/flare on the starboard wing. German aircraft carry CERBERUS ECM pod and BOZ pod. Italian aircraft are equipped with internally carried self protection jammer and may carry 2 BOZ pods. RAF has deployed an infra-red towed decoy.

- Wing control surfaces: Full-span, 43 segment, double-slotted trailing-edge flaperons. Full-span, 3-segment, leading-edge slats. 2-segment lateral control spoilers/lift dumpers at mid span ahead of the flaps. Krueger flaps on the "nib" leading-edges. Fixed “nib” has feather fairings to conform to wing contour change with sweep.
- Tail control surfaces: Slab tailplane (tailerons), actuated symmetrically for pitch control and differentially for roll. Characteristically large area dictated by short tail arm when wings swept and need to trim effective wing flaps. Tall and large area fin with rudder, dictated by short "fin arm" when wings swept fully aft at supersonic speeds.
- Airbrakes: Petal type, in shoulder position each side of the rear fuselage.
- Flight control system: All electrical, triplexed fly-by‘ wire system, with electrical and mechanical back-up modes. Command Stability Augmentation System (CSAS) employs Manoeuvre Demand control and optimizes aircraft flying qualities regardless of speed, height and stores load. Also Gust Alleviation. In the event of multiple failure, mechanical back-up allows a "get home" capability. Spin Prevention and Incidence Limiting System (SPILS) prevents loss of control or spin entry at high incidence. autopilot and Flight Director System (AFDS).
- Fuselage: Manufacture breakdown as: front fuselage, comprising cockpit aft of the rear pressure bulkhead to nose radome (accommodating radar, guns and nose undercarriage); centre fuselage with fuel tankage, intakes and inlet ducting, wing carry-through structure and undercarriage bays, dorsal fairing for services; rear fuselage comprising engine installation with bottom drop-out doors and fin and tailplane spigot mountings.
- Construction materials: By weight, aluminium alloy (72%), titanium (17%), steel (6%) and non-metallics (5%). Titanium mainly in the wing carry-through structure incorporating wing pivots, which are Teflon coated, and the engine compartment.

781 production IDS/ECR aircraft ordered, of which 733 had been delivered by early 1995. Orders by Germany (air force 210 IDS and 35 ECR; navy 112), ltaly_ (99), Saudi Arabia (48, with further 48 for 1995-97 delivery), and UK (229). Some 40 German Navy maritime strike aircraft have been transferred to the Luftwaffe, and Italy has modified 16 |DSs into ECRs, as the prototype plus 15 more. The United Arab Emirates might lease up to 19 RAF GR Mk 1s, with new Hakim stand-off weapon capability.
The initial RAF requirement was for 220 GR1 aircraft, with the type first entering service with the Tri-national Tornado Training Establishment (TTTE) at RAF Cottesmore in 1980. In June 1982, the GR1 began to enter front line service by re-equipping IX Squadron at Honington.
The first Italian prototype, aircraft P05, made it's initial flight at Turin, Italy on 5 December 1975, with the first production example for Italy following suit on 25 September 1981. Roll-out of the first Italian IDS conversion into an ECR test aircraft took place at Alenia's Caselle flight test centre on 17 March 1992.
On 26 September 1985, the UK Government and HRH Prince Sultan Bin Abdul Aziz of Saudi Arabia signed a Memorandum of Understanding, covering 48 IDS and 24 ADV Tornados, worth an estimated £5 billion (including support). This was followed on 26 March 1986 by the first flight of a Royal Saudi Air Force IDS.
