"the development and procurement of Typhoon cost the four core partner states somewhere in the region of £100 billion in FY 2022/23 terms. This cost estimate excludes weapons development, fleet operating costs, infrastructure and personnel training.
By contrast, for the entire GCAP system-of-systems, the UK has so far
committed to spending £2 billion during the initial research and scoping phases, and Italy has only
committed to €1.8 billion, with an ambition to ultimately spend another €2 billion by 2034. Recent UK announcements of
£250 million and
£656 million funding tranches have only covered the contract allocation of the previously committed £2 billion, not new money. Perhaps more worryingly, the
most up-to-date public version of the MoD’s Major Projects Portfolio lists the total estimated programme cost up to the forecast retirement date of 2070 at just £10.69 billion. This total would include through-life ownership, mid-life upgrade and operating costs, so a significant portion of it would not be allocated to funding initial development and acquisition."
