Eurofighter Typhoon IPA8

IPA8 is the eighth and last of the Eurofighter programme's Instrumented Production Aircraft (IPA): airframes built to production standard but fitted with instrumentation and telemetry for flight testing and for the development of new systems. Unlike the seven Development Aircraft prototypes (DA1 to DA7) used to mature the design, the IPAs are drawn from the production line itself, and each industrial partner operates one or more: the United Kingdom IPA1, IPA5 and IPA6; Italy IPA2; Germany IPA3, IPA7 and IPA8; and Spain IPA4 and IPA9. According to the sources consulted, the IPA fleet is owned by NETMA (the NATO Eurofighter and Tornado Management Agency), which manages the programme on behalf of the four partner nations, and is operated on loan by industry. All earlier IPAs were built to Tranche 1 standard, most with their avionics later brought up to Tranche 2; IPA7 was the first fully equipped Tranche 2 Typhoon, first flown from Manching on 16 January 2008, and IPA8 is the only aircraft in the test fleet built to Tranche 3 standard.

Its origin is tied to the consortium's decision to give the Typhoon an active electronically scanned array (AESA) radar in order to strengthen its export prospects. At the end of June 2014 the trade press reported that a Tranche 3A aircraft had been diverted from the Airbus Defence and Space final assembly line at Manching, near Munich, to be fitted with the new system. Weeks later, at the Farnborough air show in July 2014, Eurofighter unveiled the Captor-E radar installed on the British IPA5 (serial ZJ700) and announced that a second aircraft, a two-seat new-build Tranche 3 production-batch aircraft, IPA8, was under construction at Manching to join the combined E-Scan test programme. At that point the radar contract had still not been signed and the work was being funded by the contractors themselves; the development contract for the common Captor-E, worth €1 billion and funded by the United Kingdom, Italy, Germany and Spain, was signed on 19 November 2014 between Eurofighter GmbH and NETMA at the Selex ES offices in Edinburgh.

Within the division of labour of the test programme, IPA8 was assigned the electronically scanned radar, enhanced weapon integration and improvements to the mission equipment. The schedule slipped, however: the Captor-E did not enter flight trials until 8 July 2016, when IPA5 flew a sortie of around one hour from Warton, and the release marking that milestone stated that IPA8, in Germany, was also set to join the integration programme. The urgency came from export customers: Kuwait, which had become the aircraft's eighth customer in April 2016 with an order for 28 jets, was the first operator to order the Captor-E, and Qatar ordered 24 Eurofighters in 2017 with the same radar. A German Ministry of Defence report dated 19 March 2018 confirmed that integration of the Captor-E on board IPA8 had been completed successfully and that flight tests were due to begin before the end of March 2018; the same report warned that development of the radar's software remained at high risk of running late and that Germany's share of the cost had grown by more than €78 million, partly because of improvements over the originally specified functionality.

IPA8's work has fed directly into the radar's evolution. The original Captor-E became ECRS Mk 0; Germany and Spain are pursuing ECRS Mk 1, developed by Hensoldt as design authority together with Indra under contract to Airbus Defence and Space, which adds a multi-channel digital receiver and new wideband transmit/receive modules with electronic-attack capability; the United Kingdom is separately funding the substantially different ECRS Mk 2. Mk 1 is planned for retrofit to 110 Luftwaffe Tranche 2 and Tranche 3 Typhoons, for the 38 Tranche 4 aircraft of Project Quadriga and for the 20 Tranche 4 Typhoons Spain is receiving under the Halcón programme, in addition to at least five Spanish Tranche 3A aircraft to be upgraded with the new radar. In December 2024 Airbus announced the start of flight trials in Spain of a Typhoon fitted with the Captor-E under the Halcón programme, and in June 2026 Hensoldt and Indra began testing the first ECRS Mk 1 Step 1 radars, with deliveries to the German and Spanish air forces targeted for 2027.

Several details of the aircraft itself remain undocumented in the available sources: its serial number, the exact date of its first flight and the specifics of the weapons and integration campaigns flown after 2018. What is established is its singular place in the test fleet: the only two-seat IPA built as a Tranche 3, operated by Airbus Defence and Space from Manching, and the aircraft on which Germany validated the integration of the active-array radar that defines the Typhoon's next generation.
