GCAP 战斗机 GCAP Fighter（Global Combat Air Programme，全球作战空中计划）-飞行邦网

GCAP 是英国、日本、意大利三方联合研制的第六代隐身多用途战斗机，前身是英国 “暴风 (Tempest)” 项目与日本 F‑X 项目，2022‑12‑09 正式合并立项。目标 2035 年正式服役，替换英国、意大利的台风战斗机，以及日本 F‑2 战斗机。

The GCAP is a sixth‑generation stealth multirole fighter jointly developed by the United Kingdom, Japan and Italy. It evolved from Britain’s Tempest programme and Japan’s F‑X project. The formal merger was launched on 9 December 2022. It is scheduled to enter service in 2035, replacing the Typhoon fighters operated by the UK and Italy, as well as Japan’s F‑2 fighters.

二、核心设计与性能（公开指标，尚未定型）2. Design & Key Performance (public specifications, not finalised)

动力：双发自适应循环发动机 Propulsion: Twin adaptive‑cycle engines 具备2 马赫以上超音速巡航，不依赖加力长时间超音速飞行；燃油效率大幅提升，内油航程大幅优于五代机，理论可实现跨大西洋少加油飞行。

Capable of supersonic cruise above Mach 2, maintaining prolonged supersonic flight without afterburner. Substantially improved fuel efficiency and extended internal‑fuel range compared with fifth‑generation fighters, theoretically enabling trans‑atlantic flight with minimal refuelling.

隐身与传感器 Stealth & Sensors 全向深度隐身；氮化镓 AESA 有源相控阵雷达，处理数据量号称达到现有战机雷达约 10000 倍；集成强大的电子战系统，大孔径多传感器融合。

Full‑spectrum deep‑stealth design. Gallium‑nitride AESA radar, claimed to deliver roughly 10 000‑fold data throughput versus existing fighter radars. Integrated robust electronic warfare suites and multi‑sensor fusion systems.

武器与载荷 Armament & Payload 内部弹舱载弹量目标约为F‑35A 的 2 倍，兼顾制空、对地对海打击。

Internal weapon‑bay capacity targeted at roughly twice that of the F‑35A, for air‑superiority, strike and anti‑surface missions.

六代机核心能力 Core sixth‑generation capabilities

有人‑无人协同（CCA 无人僚机指挥） Manned‑unmanned teaming (MUM‑T)：本机作为空中指挥节点，指挥多架自主无人机作战。

四、项目风险与争议 4. Programme Risks & Challenges

巨额资金压力 Massive funding requirements：整体研发数百亿美元，英国财政波动多次带来预算不确定性，项目存在延期风险。

Total development costs run into tens of billions of US dollars. Volatile UK public finances create budget uncertainties with potential schedule delays.

三方需求矛盾 Conflicting operational requirements：英国侧重欧洲本土防空；日本侧重西太平洋远海作战；意大利预算有限，对采购数量有分歧。

The UK prioritises European air defence; Japan focuses on long‑range West‑Pacific operations; Italy faces tight budget constraints and divergent procurement‑volume expectations.

技术风险 Technical hurdles：自适应循环发动机、AI 空战、大规模无人僚机协同，均属于前沿技术，存在技术攻关风险。

Adaptive‑cycle engines, AI‑driven air combat and large‑scale manned‑unmanned teaming remain cutting‑edge technologies carrying significant development risks.
