The final two jets of the Initial Procurement Phase of UK F-35B Lightnings landed at RAF Marham at the end of last week. The delivery of BK43 and BK45 brings the total number of operational F-35Bs in the UK fleet to 47, reaching a significant milestone and completing one of the most advanced combat aircraft programmes in the world.
The F-35B is at the cutting edge of UK air power, operating from both land and sea aboard HMS Queen Elizabeth and HMS Prince of Wales. Each aircraft represents world-beating stealth technology, advanced sensors, and unmatched capability to keep the UK and our allies safe.
RAF Marham is home to the UK's F-35B Lightning Wing, with three squadrons at the heart of the programme. 207 Squadron serves as the Operational Conversion Unit, responsible for training the next generation of F-35B pilots and groundcrew, ensuring they are fully prepared before joining the frontline. This vital role underpins the long-term growth and sustainability of the entire Lightning Force.
617 Squadron, the legendary 'Dambusters', and 809 Naval Air Squadron form the two frontline units, delivering the operational capability that the F-35B programme was built to provide. Both squadrons are uniquely joint in their composition, drawing on the skills and expertise of personnel from both the Royal Air Force and the Royal Navy, reflecting the truly integrated nature of UK combat aviation. Whether operating from the runway at Marham or from the ski-jump flight deck of a Queen Elizabeth-class carrier, these squadrons stand ready to project air power wherever it is needed.
“I’m delighted to welcome the final aircraft of our initial procurement of F35Bs to Marham. This marks an important milestone in our 5th generation combat air power journey, reinforcing our declaration of full operational capability last year. The Lightning Wing’s stalwart service over the last year reflects how far we’ve come, with operations ranging from a truly global carrier strike deployment in 2025, to combat missions in defence of UK personnel in Cyprus and the Middle East this year. We look to the future with confidence, and this year will see us making the most of our new aircraft as we showcase our ability to project and integrate 5th-generation combat power from land and sea.”
