There is an enduring requirement for contracted labour and personnel support across aviation engineering, logistics information systems, airworthiness records, supply and enabling functions at RAF Odiham, RAF Benson and RNAS Yeovilton. The Authority are seeking a Contractor who shall provide suitably qualified and experienced personnel (SQEP) to supplement Service personnel and deliver the defined outputs where military capacity is constrained. This is an output-based personnel support requirement; it does not prescribe fixed posts or transfer the Authority’s responsibility for directing and assuring Defence outputs. The requirement is informed by persistent Service workforce pressure across engineering, logistics and enabling functions. Workforce gap data may be used by the Authority to inform planning and prioritisation; however, such data is contextual only and shall not be interpreted as a fixed staffing requirement, guaranteed workload or commitment to any specific workforce construct. The requirement supports the Authority’s need to generate, sustain and recover SUPPORT HELICOPTER FORCE (SHF) and COMMANDO HELICOPTER FORCE (CHF) capability in support of Defence-directed tasks, readiness commitments, force generation activity, contingency response and wider operational outputs. Delivery shall contribute to aircraft availability, maintenance throughput, logistics resilience, airworthiness assurance and safe operating outputs across the SHF and CHF enterprises. The Contractor shall deliver support that enables the Authority to prioritise scarce engineering, logistics, supply and enabling resources against variable operational demand. Support shall remain responsive to flying programme requirements, maintenance activity, emergent tasking, readiness cycles, future capability transition and changes in workload across output groups, functions, locations and time. The Authority does not guarantee a fixed volume of tasking. Activity assumptions, historic data and annexed output schedules are indicative and shall not be interpreted as guaranteed workload, fixed workforce demand or a prescriptive staffing schedule.
