Title: Tri-National Tornado Training Establishment
Content:  The Tornado was first shown to the British public on 14 April 1978 at RAF Boscombe Down. The RAF planned to buy 220 of them, and 165 of the ADV variant. 809 for all three countries had been ordered, with 212 for the German Air Force, 112 for the German Navy and 100 for the Italian Air Force. Cost at that time was £7.8m for the GR1 and £9.4m for the ADV. As a historical comparison, a Tornado could carry twice the bomb load of an Avro Lancaster. It was chosen above contemporary American aircraft at that time because the General Dynamics F-16 Fighting Falcon lacked all-weather capability, the McDonnell Douglas F-15 Eagle had inferior radar and electronic countermeasures and the Grumman F-14 Tomcat was too expensive. The Tornado was the first RAF aircraft with an active scanning Terrain Following Radar (TFR). The German Navy (Bundesmarine) was the first to receive their aircraft. When the TTTE was established, the RAF was concerned it may not have enough trained pilots to fly the aircraft, due to poor recruitment and perceived low pay.
Title: Panavia Tornado
Content:  Strategic Defence and Security Review (SDSR)'s publication, the Tornado's retirement was under consideration with savings of £7.5 billion anticipated. The SDSR announced the Tornado would be retained at the expense of the Harrier II, although numbers would decline in the transition to the Eurofighter Typhoon and the F-35 Lightning II. By July 2013, 59 RAF GR4s were receiving the CUSP avionics upgrade, which achieved Initial Service Date (ISD) in March 2013. On 18 March 2011, British Prime Minister David Cameron announced that Tornados and Typhoons would enforce a no-fly zone in Libya. In March 2011, several Tornados flew 3000 mi strike missions against 
Title: Eurofighter Typhoon procurement
Content:   On 9 August 2007, the UK's Ministry of Defence reported that No. 11 Squadron RAF of the RAF, which stood up as a Typhoon squadron on 29 March 2007, had taken delivery of its first two multi-role Typhoons. The RAF Typhoons were declared combat ready in the air-to-ground role by 1 July 2008. The RAF Typhoons were projected to be ready to deploy for operations by mid-2008. In July 2012, UK Defence Secretary Philip Hammond suggested that a follow-on buy of F-35A aircraft would be determined by the Strategic Defence and Security Review in 2015, with the aim of replacing the UK's Typhoons around 2030. The UK is to 
Title: Royal Air Force
Content:  The Eurofighter Typhoon FGR4 is the RAF's primary multi-role air defence and ground attack fighter aircraft, following the retirement of the Panavia Tornado F3 in late March 2011. With the completion of 'Project Centurion' upgrades, the Typhoon FGR4 took over ground attack duties from the Panavia Tornado GR4, which was retired on 1 April 2019. The Typhoon is tasked to defend UK airspace, while also frequently deploying in support of NATO air defence missions in the Baltic (Operation Azotize), Black Sea (Operation Biloxi), and Iceland. The RAF has seven front-line Typhoon squadrons, plus an Operational Conversion Unit (OCU), and Operational Evaluation Unit (OEU); No. 3 (Fighter) Squadron, No. XI (Fighter) Squadron, No. 12 Squadron (joint RAF / Qatar Air Force), No.

As part of the Delivering Security in a Changing World White Paper, on 21 July 2004, Defence Secretary Geoff Hoon detailed plans to reduce the number of Tornado F3 squadrons by one to three squadrons. This represented 16 aircraft and was the first stage in the transition to the F3's replacement, the Eurofighter Typhoon, which entered operational service with the RAF in 2005. In April 2009, it was announced that the Tornado F3 force would be reduced to one squadron of 12 aircraft in September 2009. The last operational Tornado F3s in RAF service were retired when No.

On 9August 2007, the UK's MoD reported that No. XI (F) Squadron of the RAF, which stood up as a Typhoon squadron on 29 March 2007, had taken delivery of its first two multi-role Typhoons. Two of No. XI (F) Squadron's Typhoons were sent to intercept a Russian Tupolev Tu-95 approaching British airspace on 17 August 2007. The RAF Typhoons were declared combat ready in the air-to-ground role by 1July 2008. The 
Title: Consortium
Content:  The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), MBB of West Germany, and Aeritalia of Italy. The aircraft first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multi-role design, it was able to replace several different fleets of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornado in addition to the three original partner nations. Including all variants, 992 aircraft were built.
Title: McDonnell Douglas Phantom in UK service
Content:  Tornado, so the UK alone began the process, and the authorisation for what came to be known as the Tornado Air Defence Variant (ADV) was issued in March 1976. The initial plan was for the Tornado to replace the remaining two squadrons of Lightnings, as well as all seven squadrons of Phantoms. While the Tornado was in development, the RAF looked at interim measures to replace the Phantom, which had been in service for over a decade by 1980, and was beginning to suffer from fatigue; one proposal was the lease or purchase of F-15 Eagles to re-equip 19 and 92 Squadrons, the units stationed in Germany. Further suggestions were that 
Title: Al Udeid Air Base
Content:  Between 2005 and 2009 the airbase was used by the British Royal Air Force with transport and fast-jet aircraft to support Operation Telic (Iraq War) and Operation Herrick (War in Afghanistan). These included 6 to 8 Tornado GR4 aircraft drawn from different parts of the Royal Air Force as well as multiple Vickers VC10 from the No. 101 Squadron RAF. British Tornados were equipped with a range of stores, including the Vicon Recce Pod, LITENING targeting pod, 1000 lb HE bombs, Paveway II and Paveway III laser-guided bombs, and the RAPTOR Recce Pod. They were chosen for their currency and up-to-date modification state. The RAF aircraft were accompanied by nearly 400 personnel, of which approximately 130 were aircraft engineers while the remaining 270 were active in support 
Title: McDonnell Douglas Phantom in UK service
Content:  Squadron detached nine of its aircraft to RAF Stanley to provide air defence for the Falkland Islands. In March 1983 23 Squadron took up the role, remaining stationed there until October 1988, when they were replaced by 1435 Flight. Initially, it was intended that Phantoms and Tornados would serve alongside each other. A total of 152 Tornado F.3s were ordered for the RAF, enough to convert four squadrons of Phantoms and two of Lightnings, but insufficient to completely convert every air defence squadron. The intention was to retain a pair of UK based Phantom squadrons at RAF Wattisham, alongside a pair of Tornado units at RAF Coningsby to provide air defence
