RAF Photographic Reconnaissance Unit

Valerie Vaz Excerpts

Thursday 17th July 2025 Westminster Hall

[Esther McVey (Tatton) (Con)]

I congratulate the hon. Member for Carlisle (Ms Minns) on securing this debate and on the way she recounted such moving and powerful stories. Each story is unique, but they are all united by themes of selflessness, quiet heroism and unwavering commitment to our country.

I will pay particular attention to Tatton’s own local photographic reconnaissance unit hero, Flight Sergeant William Douglas Stepford. William was born in Handforth, married his sweetheart Bessie, and joined the RAF Volunteer Reserve. He trained as a navigator and was posted to 540 Photographic Reconnaissance Squadron. Sadly, in August 1944, while flying a reconnaissance mission over Munich, William’s aircraft was shot down over Hallstatt. He was just 24 years old. That was alongside his pilot, Flight Lieutenant Desmond Laurence Matthewman, DFC.

For so many reconnaissance flights, the missions were carried out in exceptionally difficult circumstances—clandestine, unarmed and often solo flights over enemy territory, which put the individuals in unique danger. The death rate was nearly 50%, with one of the lowest survival rates in the war, but the unit captured 26 million photographs over the course of the war, taken by 1,746 reconnaissance pilots and navigators.

The efforts of the unit were essential, and nowhere more so than in the planning of D-day, also known as Operation Overlord, the most significant victory of the allies. That was the most comprehensive reconnaissance operation of the war. In the months before the invasion, low-level reconnaissance flights over Normandy provided critical intelligence about German beach defences and key infrastructure. Without that information, the comprehensive plans for Operation Overlord, and its ultimate success, would not have been possible.

Tatton played a unique role in the preparations. The quiet village of Lower Peover played host to many of the great Americans of history, from General George Patton to General Eisenhower—later President Eisenhower, of course. Peover Hall became the headquarters of the vast US third army. In the local pub, the Bells of Peover, Patton and Eisenhower met to discuss plans for the invasion. Today, still, in that pub, in the upstairs dining room—now, aptly, named The Patton—can be found a small pocket diary on display. Spread across the pages for 5 and 6 June 1944, an unknown serviceman wrote in block capitals:

“D-day tomorrow. Everybody quite excited. We land at Arromanches, clear three villages of Bayeux.”

Last year, on the 80th anniversary of D-day, I was pleased to unveil a blue plaque to mark the pub’s place in history alongside the lord lieutenant of the county of Cheshire, Councillor Anthony Harrison, and the landlord of the pub, Phil Smith, and surrounded by the local community. The plaque serves as a reminder of the unique history of this beautiful village in Cheshire.

Surrounding villages also played their part. From the secret aviation fuel plant in Plumley to the home guard at Shakerley Wood and the parachute training school at Tatton Park, each village, each unit and every individual had a role. Without those such as William Stepford putting themselves in the line of danger, the admiralty would not have had the intelligence it needed for operations like D-day. Without them, history would have taken a different course.

Alongside Members here today from across the House, I welcome plans for this memorial. I am delighted that planning has already begun, but on this occasion, can I just ask the Minister to give us the full timeframe and completion date for this memorial? It is high time that their legacy is honoured by all of us and the entire country.

[Valerie Vaz (in the Chair)]

If everyone sticks to the informal time limit of four minutes, we should get everyone in.

It is pleasure to serve under your chairship, Ms Vaz. I thank the hon. Member for Carlisle (Ms Minns) for affording us all the opportunity to recognise a wonderful part of this nation’s history. It is a real pleasure to see the Minister in his place. He is held in high esteem by all hon. Members—not to put any pressure on the answers that he will give shortly. I say that in jest.

It is a great pleasure to speak about the extraordinary role of the RAF Photographic Reconnaissance Unit during the second world war—a unit whose daring missions and critical intelligence gathering were pivotal to the allied victory. The PRU’s pilots, who flew unarmed planes into enemy skies, showed a bravery that reminds us of the men of the merchant navy, who manned unarmed ships through dangerous waters.

In 1940, the RAF PRU rose from Sidney Cotton’s civilian Heston Flight, officially becoming the No. 1 Photographic Reconnaissance Unit in November 1940. It was tasked with capturing high-resolution aerial photos of enemy territory. We have to consider what that means—it means it operated with little or no protection. The PRU became our eyes in the sky.

The pilots would fly modified, unarmed aircraft, such as Spitfires and Mosquitoes, at incredible speeds and altitudes of 44,000 feet, evading enemy detection to gather intelligence. The images meticulously analysed by the RAF Medmenham’s allied central interpretation unit revealed German secrets from rocket programmes to fortified defences. In 1943, the PRU’s reconnaissance over Peenemünde revealed Germany’s V1 and V2 rocket development, prompting Operation Hydra, a bombing raid that delayed the use of those weapons by months, potentially saving countless lives.

For D-day in 1944, the PRU’s 85,000 daily images mapped the Atlantic wall, enabling precision planning for the Normandy invasion. It is impossible to overstate the courage demanded for these missions. Just like the merchant navy, whose crews worked mostly on unarmed ships, braving U-boat-infested waters to deliver vital supplies, the PRU pilots flew unarmed planes in skies heavy with Luftwaffe fighters.

Tragically, the PRU suffered the highest casualty rate of any RAF unit. Pilots such as Wing Commander Adrian Warburton, a daring pilot who on 11 November 1940 flew a recon mission over a huge flight of Italian battleships in Taranto harbour, not far from Malta—flying so low he could almost reach out and touch the vessels, and was very aware of their painted names. He was shot down in April 1944. His remains were not discovered until 2002 in a field in Bavaria, around 30 miles west of Munich, still strapped in his plane’s cockpit.

The PRU’s strength was supported by pilots and bases around the Commonwealth and beyond. I am very proud to say that Northern Ireland had a role to play in that, with a vital RAF hub supporting the PRU at airfields in Aldergrove and Limavady, which were key locations for Coastal Command operations until 1942.

The Commonwealth’s role in the PRU was significant thanks to the Canadian, Australian and New Zealand airmen, and of course the invaluable contributions of the Polish airmen whose feats are the stuff of legend. No. 318 Polish Fighter-Reconnaissance Squadron supported reconnaissance efforts as well, and their flights over Peenemünde were critical. Polish intelligence from the Home Army provided ground-level reports that complemented PRU imagery, especially after rocket testing shifted to Blizna in Poland.

The PRU’s innovations saw techniques such as “dicing”, where pilots skimmed treetops under fire—my goodness, that makes your head spin. Night photography using the Edgerton D-2 flash system and infrared film by 1945 enabled the PRU to break enemy camouflage in darkness. Who thinks all these up? I know I could not, but those people did. Those developments, teamed with cameras like the F24 and F52, delivered precise intelligence, paving the way for today’s modern reconnaissance. They set the examples for the rest of us.

The PRU’s legacy remains firm and indisputable in the National Collection of Aerial Photography, while those brave, precious lives lost are commemorated by the Commonwealth War Graves Commission with memorials around the UK, such as at Runnymede, and also in France, Malta, Sicily, Tunisia and Singapore. That demonstrates how far their reach extended.

In conclusion—I am conscious of your time limit, Ms Vaz, which is why I am speaking at 100 mph—to those brave pilots, our eyes in the sky, especially those who lost their lives flying high-risk spying missions to secure our liberation, we owe our profound, lasting admiration, respect and gratitude. Their legacy compels us to be the keepers and guardians of their history.

[Valerie Vaz (in the Chair)]

As the hon. Members who have spoken so far have been so good with their time, other Members have a bit more time.

[Ms Minns]

It has been a genuine privilege to hear so many tributes and stories about those who served in the RAF unarmed reconnaissance units from so many constituencies. I thank my hon. Friends the Members for Morecambe and Lunesdale (Lizzi Collinge), Cities of London and Westminster (Rachel Blake), West Ham and Beckton (James Asser), North West Leicestershire (Amanda Hack) and Glasgow North (Martin Rhodes), and particularly my hon. Friends the Members for Ealing Southall (Deirdre Costigan) and Bishop Auckland (Sam Rushworth) for their comments.

I am really grateful to Opposition Members for their extremely thoughtful and kind comments about the people who came from their constituencies to serve our country so bravely. I pay tribute to the comments made by the right hon. Members for Tatton (Esther McVey) and Aldridge-Brownhills (Wendy Morton) and the hon. Member for Reigate (Rebecca Paul), and I thank the hon. Member for Strangford (Jim Shannon) for his wonderful contributions to all our debates. I also thank the Liberal Democrat spokesperson, the hon. Member for Epsom and Ewell (Helen Maguire), for sharing stories from her constituents.

I thank the shadow Minister, the hon. and gallant Member for Exmouth and Exeter East (David Reed), for his contribution, which brought to life the stories of the people who came from his constituency. I do think it is a little regrettable that, sadly, this debate, which was introduced to pay tribute to those who served in the photographic reconnaissance unit and to thank those who have for six years driven the AA810 campaign, was momentarily and unnecessarily diverted to score a cheap political point.

I would like to return to the purpose of this debate, which is to pay tribute to those who served so gallantly, so bravely and so selflessly all those years ago. I cannot begin to imagine the absolute terror, which the hon. and gallant Minister spoke about, in that moment before take-off, knowing that they might not return home that evening. We can never thank enough those who did return and those who paid that ultimate sacrifice. We should also place on the record our thanks to the Commonwealth War Graves Commission for the work that it does throughout the year to ensure that we have a permanent remembrance for all those who paid the ultimate sacrifice.

Let me pause momentarily to thank two individuals from the campaign, Tony Hoskins and David Robertson, for all they have done in Parliament. We have heard this afternoon just how much it has meant to all of us that your contribution has been able to bring to life what happened in our constituencies over 80 years ago, and I thank you for that.

[Valerie Vaz (in the Chair)]

The Chair does too.

[Ms Minns]

I very much welcome the Minister’s comments. I am sure that, with the right will, those riddles of GDPR can be successfully negotiated and we can finally have the full stories of the remaining people who served so gallantly in the PRU. On that note, I pay my respects once again to all the airmen and to all those who served in one shape or another in the PRU. They served their country with such distinction, and we remember the sacrifices that they made—lest we forget.

[Valerie Vaz (in the Chair)]

Thank you to all hon. Members who have contributed to this debate.

Question put and agreed to.

Resolved,

That this House has considered the role of the RAF Photographic Reconnaissance Unit during the Second World War.
