Reference excerpt

The Global Combat Air Programme (GCAP; Italian: Programma Aereo da Combattimento Globale; PACG; Japanese: グローバル戦闘航空プログラム, romanized: Gurōbaru Sentō Kōkū Puroguramu) is a multinational initiative led by Italy, Japan, and the United Kingdom to jointly develop a sixth-generation, multi-role, stealth fighter, informally referred to as Tempest. Administered through the GCAP International Government Organisation (GIGO) and designed and manufactured by Edgewing, a joint ventured formed by Leonardo, BAE Systems and JAIEC (a consortium led by Mitsubishi Heavy Industries), the programme aims to replace the Eurofighter Typhoon in service with the Royal Air Force (RAF) and Italian Air Force, and the Mitsubishi F-2 in service with the Japan Air Self-Defense Force. On 21 July 2026, Canada joined as an observer to the programme. 9 December 2022, the governments of Italy, Japan, and the United Kingdom, jointly announced that they would develop and deploy a common fighter jet, merging their previously separate sixth-generation projects: the United Kingdom-led BAE Systems Tempest developed with Italy, and the Japanese Mitsubishi F-X. This was formalised with a treaty signed in December 2023 in Japan which established the GIGO. The Joint venture Edgewing would officially launch in June 2025. Edgewing received its first internation £686 million contract in April 2026, followed by a larger £4.6 billion contract in July marking the transition from national contracts by each partner, to a fully-fledged international programme. The aircraft was originally expected to enter service in 2035. Leonardo has estimated that as many as 350 aircraft could be ordered between the three nations. In July 2026, Leonardo CEO Lorenzo Mariani told reports that the aircraft could enter service two years ahead of its 2035 target date.

Background

Japan (F-X)

Japan, an island nation, has a disproportionately vast air defence identification zone given the size of its land territory, and it was expected that the country would have to protect it with a smaller fleet of fighters compared to those of its growing neighbours with much larger populations. To address this issue, the Ministry of Defence decided in 2010 that Japan's next-generation fighter had to be highly information-based, intelligent, and capable of instantaneous response (i3 fighter). At the time, the fighter fleet of the Japan Air Self-Defence Force mainly consisted of the Mitsubishi F-15J and the Mitsubishi F-2. The former is a variant of the F-15, manufactured by Mitsubishi Heavy Industries (hereafter referred to as Mitsubishi) under licence, while the latter was developed by Mitsubishi and Lockheed Martin based on the F-16 in the 1990s. While the F-15J was set to be replaced by the F-35, a replacement for the F-2 needed to be found before its planned retirement in the 2030s.

Following the USA's decision not to allow the export of the F-22 Raptor to any other country in 2007, Japan began looking for a domestic solution to field a new fighter aircraft to replace its Mitsubishi F-2 fleet. From the mid-2000s Japan began funding various research programmes involved in fighter design culminating in the Mitsubishi X-2 Shinshin experimental aircraft which took flight on 22 April 2016. This research and the data collected from the X-2 programme would feed the development of Japan's main fighter effort, the Mitsubishi F-X programme. The IHI Corporation completed a prototype for the XF9 engine in 2018. In 2018, after more than a decade since America's refusal to export the F-22, Lockheed Martin proposed a potential Japan-America collaboration project to develop the F-2 successor based on the F-22 and F-35, but this was rejected by Japan.

Worked examples

Example 1 — a first encounter with Global Combat Air Programme

Start with the simplest possible case. Write down what Global Combat Air Programme claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Global Combat Air Programme before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Global Combat Air Programme ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Global Combat Air Programme

In research: Global Combat Air Programme appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Global Combat Air Programme in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Global Combat Air Programme is common in secondary-school and first-year university syllabi. It links to neighbouring topics Proposed aircraft of Italy, Proposed aircraft of the United Kingdom, Sixth-generation jet fighters, so understanding it makes those chapters shorter.
In everyday life: Look for Global Combat Air Programme outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
