But due to failings of both the MoD and the global programme, the level of overall UK F‑35 capability is currently lower than the MoD intended it would be by now at the time of its 2013 business case, and will be for several years.
Since 2010, MoD decisions to meet wider affordability challenges have led to delays in the delivery of aircraft and key infrastructure. The MoD has also failed to address personnel shortages and does not expect to fill gaps until 2028. And the global programme has had a series of issues which have delayed production and hindered logistical support while technology upgrade and support costs have also increased markedly over recent years.
