RAF E-7 Wedgetail Programme

Ian Roome Excerpts

Wednesday 16th July 2025 Westminster Hall

[Ian Roome (North Devon) (LD)]

It is an honour to serve under your chairmanship, Sir Christopher. I thank the hon. Member for Dumfries and Galloway (John Cooper) for bringing this important debate to Westminster Hall. I concur with the right hon. Member for Rayleigh and Wickford (Mr Francois): the Liberal Democrats also welcome Air Marshal Harv Smyth to his new appointment as Chief of the Air Staff—congratulations to him. He will be a fine leader.

The E-7A Wedgetail represents a major update to the UK’s airborne warning and control capability. Future-proofing our armed forces is something that the Liberal Democrats strongly support. Wedgetail’s predecessor, E-3D Sentry, first entered service in the Royal Air Force around the same time as I entered the Royal Air Force, but fortunately it stayed at the cutting edge for a good deal longer. Indeed, the aircraft was still flying operational sorties and keeping the UK safe right up until it was decommissioned in August 2021.

Although Sentry has since made some extra flights over home soil, the UK has officially been without an airborne warning and control capability for several years. That is just one example of how the last Government allowed our armed forces to be hollowed out over time.

[Cameron Thomas]

To their credit, the Conservatives have been quite open in lamenting the drawdown of the Wedgetail project, but will my hon. Friend join me in asking the Government how committed they are to the Wedgetail programme and to the initial order of five?

[Ian Roome]

I agree with my hon. Friend, and I am sure that the Minister will reply.

Unfortunately, Sentry’s intended replacement, the Wedgetail programme, has already been through some major turbulence during its early years, from questions over the fairness of the MOD’s procurement decision in 2018 to a two-year production delay and an order reduction from five airframes to three under the last Government’s integrated defence review—a move that Boeing says slowed down the project, and a decision described as an “absolute folly” even by the then Defence Committee.

We now read news reports that the Trump Administration are seeking to cancel Wedgetail orders for the US air force over claims that it would be too vulnerable in contested airspace, casting doubt over the programme’s future interoperability and cost. I am sure that many hon. Members will also have seen the recent letter signed by 19 retired US four-star generals criticising that decision. The United States aspires to a fully space-based replacement, but that is still many years away. With hindsight, knowing what we know about Russian aggression in eastern European airspace, the timing of all this could hardly be more perilous.

Just a few weeks ago, my colleagues on the Defence Committee and I visited Allied Air Command in Ramstein, Germany. The UK is committed to a 24/7 NATO air policing mission, and the strategic defence review states that the UK’s defensive posture should be firmly “NATO first”. The Liberal Democrats believe that the UK should work as closely as possible with our European allies on our shared defence, and that our military should complement our allies’ capabilities.

In addition to raising the UK’s defence spending to 2.5% and beyond, it is essential that we co-ordinate our allied air forces in Europe, especially those of our Nordic and Baltic partners, to give more bang for buck. In the European airspace, this airborne capability is very specialised. Various NATO forces still operate old E-3 aircraft, including Germany, Turkey, Greece, Italy and Norway. France and some Scandinavian air forces also operate similar aircraft from rival manufacturers such as Saab and Northrop Grumman.

However, as has been pointed out before the US Senate Committee on Armed Services, the cost of repairs to the old E-3 fleet keeps increasing, and their availability to fly keeps decreasing. Australia, South Korea and our European allies in NATO, faced with the same choice as the UK, are choosing to replace their E-3 fleets with Wedgetail.

Next month, Australian Wedgetails will be deployed to Poland as part of efforts to support Ukraine. European Wedgetails are not expected to enter service until 2031. That may be six years of expensive repairs to ageing aircraft—six years during which UK Wedgetails could play an outsized role in European air defence, but only if the current Government work to rebuild our armed forces capacity, and only if our aircraft are ready to fly.

As the Public Accounts Committee keeps highlighting, large overspends are unacceptable. Long delays that leave this country’s Air Force without an essential capability are a sign of a procurement system that is badly broken. The strategic defence review recommends more Wedgetails for round-the-clock airborne surveillance, and says there may even be cost-sharing opportunities with NATO allies.

I put these questions to the Minister. First, do the Government plan to meet our defence commitments this way, either by ordering additional Wedgetails, in lockstep with our allies, or even seeking an alternative? Secondly, what steps will the Government take to improve the Ministry of Defence track record on this kind of aircraft procurement, so that our defence of NATO airspace is never put in doubt again?

--- Later in debate ---

[The Minister for the Armed Forces (Luke Pollard)]

I congratulate the hon. Member for Dumfries and Galloway (John Cooper) on securing this debate. I have to warn him that he is sounding like a very good shadow Minister Padawan on these matters, so I expect him to be forceful in pursuing this type of stuff.

As hon. Members will have spotted, I am not the Minister for Defence Procurement and Industry—I am the slighter camper version—but I hope to be able to answer some of the questions raised in the debate about what is a very important programme for the Royal Air Force. I will first give a little background and history, which a number of Members have raised, and then turn to a number of the questions and points that hon. Members have also raised.

May I, too, place on record my congratulations to Harv Smyth on becoming the new Chief of the Air Staff? Having worked with Harv for the past year, I know that the RAF will be in very good hands. With Sir Rich Knighton becoming the new Chief of the Defence Staff, we have an incredibly capable team, with very good RAF experience. Just to ensure a full house, I also welcome General Gwyn Jenkins as First Sea Lord—as a Navy brat, it would be remiss of me not to mention the senior service.

[Ian Roome]

Will the Minister also join the Worshipful Company of Engineers in congratulating Sir Rich Knighton on being the first engineer to become the chief of the Royal Air Force? Being ex-RAF, it is nice to have an engineer who has never been a pilot as the chief of the Royal Air Force.

[Luke Pollard]

I thank the hon. Gentleman for that intervention. It is worth noting, because to succeed we need people at the point of the spear and we need people who are the spear. All too often in our debates, we neglect those who support, who engineer, and who are the backbone of our military. Having Sir Rich in the new role as CDS will be a good encouragement to all those who find a career in our armed forces: there is a bright future ahead of them if they work hard and succeed.

At a time of increasing threats to our security and rapid developments in technology, it is essential that we upgrade our airborne early warning and control capabilities. Members have mentioned it, but when we say, whether from the Dispatch Box as a Government or when we were in opposition, that the last Government hollowed out and underfunded our military, it is precisely such capability gaps that we are talking about. The hon. Member for Dumfries and Galloway, who secured the debate, described it as not just a capability gap, but a credibility gap, and those are precisely the kinds of gaps that we so critiqued in opposition. They are also the gaps that we have to fill, now that we are in government.

The UK’s E-7 Wedgetail programme will provide the significantly improved performance that we are looking for, offering greater speed, range, endurance and crew capacity. By improving detection, it provides earlier warning of more challenging threats at greater distances than before, increasing the time available for offensive and defensive action, and so boosting the lethality, survivability and resilience of the joint force. Wedgetail is not only the most capable and effective airborne early warning and control platform in operation today; it also has the growth path to match the expected threat over the next 20 years and beyond. We will continue to fully prepare for the introduction of E-7 Wedgetail to the RAF fleet.

To support the introduction of E-7, a joint operational conversion unit, 42 Squadron, has been re-formed at RAF Lossiemouth. The squadron will train all aircrew and engineers to operate the Poseidon maritime patrol aircraft and the Wedgetail airborne early warning and surveillance aircraft. The Lossiemouth development programme is delivering vital infrastructure, including a new engineering building, accommodation and squadron facilities, and the UK has been helped by Australia to prepare for Wedgetail. I put on record my thanks to the Royal Australian Air Force. Since its inception in 2018, 30 RAF personnel have undergone training on the E-7A Wedgetail aircraft, which is already in operation with the Royal Australian Air Force. We are extremely grateful to our Australian friends for their support.

I am glad that the hon. Member for Meriden and Solihull East (Saqib Bhatti) could put on record the difference between Birmingham and Solihull. As a Plymouth MP, I am forever making the distinction between Devon and Cornwall, although we are the best of friends at the same time. The hon. Member made the argument about the economic contribution that Wedgetail makes to his constituency, and my hon. Friend the Member for North Durham (Luke Akehurst) spoke about the wider nationwide supply chain. That contribution is vital.

Wedgetail is already bringing economic benefits to the UK. Three Boeing 737 aircraft are currently being modified at STS Aviation in the constituency of the hon. Member for Meriden and Solihull East, where around 100 skilled jobs have been created, in addition to 200 jobs supporting infrastructure at RAF Lossiemouth. He is right to say, as my hon. Friend the Member for North Durham did, that these are high-skilled jobs. They are precisely what his constituency needed supporting after the collapse of Monarch Airlines. It has meant that so many people could transfer into new roles at STS.

The work at STS, supplemented by Boeing and Northrop Grumman personnel who have worked on previous E-7 conversion programmes, is important. Boeing Defence UK expects a further 70 to 100 jobs to be added to support the aircraft in service at Lossiemouth. The Government’s longer-term aim is to grow the UK industrial base in support of Wedgetail, including potentially to support NATO and other global customers as they commit to E-7 in future years. Members will know that the strategic defence review was clear that defence is an engine for growth, and we need to continue to support our allies in looking to E-7 Wedgetail to provide some of their long-range surveillance opportunities.

The hon. Member for Meriden and Solihull East asked about exports. It is a priority for this Government to procure systems that are not only better value for money for the UK armed forces, but built in such a way that we do not make them so Gucci that they are available only for the Brits. That has been a flaw of previous procurements, and we are clear, in rebuilding and recapitalising our armed forces and many of their capabilities—including filling capability gaps that we inherited from the previous Government—that we have to ensure that those platforms are exportable, that there is a work share for British companies, and that defence can be a real engine for growth. He will be aware of the high-level ambition set out in the strategic defence review to deliver that.

Members will also know that we hope to publish the defence industrial strategy in due course and, towards the end of the year, the defence investment plan. That will set out what we are spending, not just on kit and equipment, as previous iterations of the equipment plan did, but on infrastructure and people. Those are what the MOD wishes to spend the increased amounts of defence funding on. Exports will be a key part of that, and I encourage the hon. Member for Meriden and Solihull East to continue to make that case.

However, disappointingly, the E-7 Wedgetail programme has experienced delays. These are due, first, to wider challenges faced by the entire global aviation industry—such as shortages of materials, parts and skilled labour—and, secondly, to more specific programme issues, including complex certification work that Boeing has had to undertake to meet assurance requirements.

The Ministry of Defence is working closely with Boeing to minimise the impact of these issues, and the Minister for Defence Procurement and Industry has regular conversations with Boeing to emphasise the importance of delivering this capability.

As a result, E-7 Wedgetail is scheduled to enter service with the Royal Air Force in 2026. The RAF’s mission system has been significantly upgraded, making our Wedgetail aircraft distinct from those of other nations. That has required substantial certification and safety checks to ensure the system meets the standards required. We are working flat out to get a fully compliant aircraft into service as fast as possible, and we are holding suppliers to account for their part in that. Since concluding previous flights in October 2024, the aircraft has continued its mission systems installation.

E-7 Wedgetail completed its fourth test flight last week and will perform a fly-past at the royal international air tattoo at RAF Fairford, which the Minister for Defence Procurement and Industry will attend—I believe other hon. Members may be visiting as well. Test and evaluation will take place across multiple sites in the UK, with the next phase starting this month. This is a detailed process to demonstrate that each system operates as designed. Subsequent phases will be running through to 2026.
