Despite ongoing controversy with the United States regarding Malvinas, the United Kingdom continues advancing its F-35 fleet expansion program, aiming to acquire up to 138 aircraft. The F-35 program remains a central component of modernization efforts for both the Royal Navy and the Royal Air Force (RAF). Recent developments confirm progress in deliveries, even as geopolitical tensions persist.
By the end of last week, Lockheed Martin completed the delivery of the 46th, 47th, and 48th F-35 aircraft, marking the conclusion of the Initial Acquisition Phase. This milestone represents a significant step forward in the UK’s long-term defense strategy, which relies heavily on fifth-generation stealth fighter capabilities. The completion of this phase provides a foundation for scaling up future deliveries under the broader procurement plan.
According to details released by the U.S.-based manufacturer, the newly delivered aircraft arrived at RAF Marham, currently the main operating base for the UK’s F-35 fleet. The company also highlighted that these jets include components manufactured within the United Kingdom by domestic industry. This industrial participation supports approximately 20,000 skilled jobs while contributing to national defense capabilities, with projections estimating up to £45.2 billion in economic benefits for the UK over the lifetime of the global F-35 program.
With the arrival of the 48th aircraft and the completion of this initial phase, British analysts indicate that London must now accelerate efforts to define the delivery schedule for the remaining aircraft needed to reach the target of 138 units. Local media reports emphasize that this issue is particularly relevant given the delays affecting the F-35 program, especially regarding the Block 4 upgrade, which is required to enable the integration of new weapons systems.
Previous reports suggested that Lockheed Martin could deliver up to 75 F-35 aircraft by 2033, as stated by Minister of State for Defence Luke Pollard in response to a parliamentary question raised by Lord Alan West. In that exchange, the inquiry asked, “to ask His Majesty’s Government when they expect to have received the 74 (sic) F-35 Lightning aircraft,” to which the response was that “the Department expects to receive its 75th F-35 aircraft by the end of 2033.” However, UK authorities have not yet published the new Defence Investment Plan, where these projections are expected to be confirmed.
In parallel, the United Kingdom is expected to incorporate 12 F-35 aircraft of the A variant as part of this broader modernization effort. These aircraft would be assigned to the Royal Air Force with the objective of strengthening its capabilities, including participation in nuclear deterrence missions involving the carriage of U.S.-origin B61 bombs. These weapons are currently stored at various locations across Europe, and it is considered that two British bases could potentially host them following refurbishment work.
According to statements made in January by Defence Minister Luke Pollard, this development would not represent an increase in the United Kingdom’s independent nuclear deterrent, which relies exclusively on submarine-launched missiles operated by the Royal Navy. Instead, these aircraft would be integrated into NATO’s dual-capable aircraft framework, within which the United States retains control and custody of the nuclear weapons. Following recent tensions between Washington and European allies, including the United Kingdom and Spain, it remains unclear whether this arrangement will continue to be a viable option for British forces in the future.
