As this yr’s Defence and Safety Tools Worldwide (DSEI) exhibition prepares for its last day at ExCel London, let’s solid our eyes over a few of the tales which have emerged so removed from the most important trade occasion.
DSEI, held in London each two years, is at all times a spotlight for information regarding defence and safety. DSEI 2023 noticed the official launch of the multinational International Fight Air Programme (GCAP), because the exhibition responded to the Russian invasion of Ukraine with an elevated concentrate on counter unmanned aerial programs (C-UAS) expertise and increase Europe’s army forces with superior, however extremely scaleable, new designs.
2025’s version, coming three years after Russia’s invasion, and following huge geopolitical shifts ensuing from quickly evolving occasions throughout the Center East, has been extra hotly anticipated (and protested) than ever. The Aviationist contributor James Grey, who attended DSEI on Sept. 11, famous that GCAP and developments round FC/ASW, now named STRATUS, seemed to be key focuses this yr amongst these attending, however that a method effectors had been the ‘theme’ of the occasion.
Edgewing Debut
Making its first DSEI look underneath the Edgewing banner – the title of the worldwide organisation that may oversee its improvement – there have been numerous bulletins regarding the UK-Japan-Italy GCAP fighter. A mockup of the plane was proven off to arriving company as a ‘gate guard’, drawing notable curiosity from Hiroshi Suzuki, the a lot celebrated Japanese Ambassador to the UK.

Nearer inspection of the mannequin by defence journalists revealed an fascinating nod to a possible characteristic for the plane which has but to be introduced or confirmed. Trying on the rear of the plane, the exhausts look like formed in a manner which may counsel the combination of F-22 Raptor-style 2D thrust vectoring. Alternatively, it is usually attainable that the form is solely a part of the airframes’ radar and infrared signature discount measures.

Thrust vectoring was meant to be included on Japan’s Mitsubishi F-X future fighter, which was ultimately merged into GCAP. The expertise was seen used on the X-2 testbed flown in 2016. Upgrades to the Eurofighter Hurricane that included thrust vectoring had been additionally beforehand proposed, however this improvement has by no means been totally funded. Amongst pilots, views on thrust vectoring differ broadly. The thrust vectoring capabilities of plane just like the F-22 Raptor and Sukhoi Su-30 are enormous crowd-pleasers at airshows, and undoubtedly provide a rare functionality to outmaneuver an opponent in a detailed quarters dogfight.
Nevertheless, detractors level out that the usage of thrust vectoring can result in an extreme bleed of kinetic power, which means that if a pilot is unable to impact a ‘kill’ after performing a thrust vectoring-enabled maneuver they could subsequently be left as a sitting duck for a counter assault by weapons or missiles. Its utility primarily in shut quarters fight can also be criticized with trendy air to air engagements extra steadily undertaken at longer ranges.
Additionally introduced was an enlargement in the usage of airborne testbeds for GCAP improvement. The UK has already commissioned a Boeing 757 primarily based testbed airframe, named Excalibur, which has been energetic from MoD Boscombe Down. Augmenting Excalibur, it seems that Italy will discipline a testbed primarily based on a Gulfstream enterprise jet, whereas Japan will modify a Kawasaki C-2 transport plane.
GCAP will now doubtless assist 3 flight check airborne labs for radar/sensors/comms – 757 Excalibur in UK, Gulfstream bizjet in Italy, and modified C2 transport in Japan.

FC/ASW Turns into STRATUS
Some extra readability concerning the MBDA Future Cruise/Anti-Ship Weapon, or FC/ASW, was revealed on Sept. 10 when the programme was formally given the title STRATUS. STRATUS will comprise two sorts of missile – STRATUS LO (Low Observable), previously often called TP15, will probably be a subsonic, stealthy cruise missile designed to exchange MBDA’s Storm Shadow/SCALP-EG, whereas STRATUS RS (Speedy Strike), previously RJ10, will probably be a sophisticated ramjet-powered, high-maneuverability supersonic (Mach 3-5) missile. France leads improvement on STRATUS RS, whereas the UK leads on STRATUS LO.
Mockups displayed of each missile varieties present roughly related proportions. If this carries over to the ultimate designs, each missiles might be able to be launched by an equally huge collection of platforms. In addition to conventional air-launch from fighter plane and vertical launch from ships, there’s additionally future potential for floor launch. The missiles may have a excessive diploma of commonality.
Italy is reportedly making approaches in direction of becoming a member of the UK-France group, expressing curiosity in each missile varieties.
Pink Arrows KAI T-50
As one of many rumored contenders for the UK’s subsequent jet coach, a scale mannequin of the Korea Aerospace Industries T-50 was proven off in a livery clearly primarily based on that of the Royal Air Drive’s Pink Arrows show group. Whereas the RAF seeks to exchange the Hawk T2 as its superior jet coach, it’s the alternative of the venerable Hawk T1s utilized by the show group that has arguably generated probably the most dialogue in UK mainstream media.
The T-50 faces robust competitors right here, with homegrown Aeralis additionally making its presence recognized at DSEI with its progressive configurable airframe idea. Although Aeralis is a brand new child on the block, having but to provide a flying airframe, its British roots will assist its case by way of selling UK trade – a key driver behind the Pink Arrows. Different contenders embody Leonardo’s M-345 and M-346 plane, the Boeing-Saab T-7 Pink Hawk, and the Turkish Hürjet.

Jet-powered CCAs on Queen Elizabeth class by 2026?
First Sea Lord Basic Sir Gwyn Jenkins, talking at DSEI 2025 as the primary ever Royal Marine to guide the Royal Navy, delivered a significant speech on Sept. 9 outlining his intent to quickly reshape and strengthen the Royal Navy. One aspect of this would be the fielding of hybrid manned-unmanned air wings on the Queen Elizabeth class plane carriers, which was really helpful within the 2025 Strategic Defence Overview.
Jenkins claimed that by the top of subsequent yr (2026), a jet-powered unmanned collaborative fight plane (CCA) idea will probably be launched from one of many Royal Navy’s two carriers. This may almost certainly be HMS Queen Elizabeth, which is at the moment dry-docked in Scotland for a common refit and hull re-certification. The Basic says that by the point of the Royal Navy’s subsequent Indo-Pacific service deployment, the service air wing will probably be “virtually unrecognisable”.
Although nonetheless centered across the F-35B, with Merlin helicopters for anti-submarine warfare (ASW), the air wing will probably be augmented by an array of unmanned plane – each mounted wing and rotary wing – that may prolong sensor ranges, add extra weapons capabilities, and supply persistent intelligence, surveillance, and reconnaissance (ISR) across the service strike group. Restricted examples of this may be seen on the present CSG 25 deployment, the place HMS Prince of Wales has deployed with numerous Malloy T-150 drones for cargo switch, and Puma drones for ISR.
Atlantic Bastion
Uncrewed floor vessels (USVs) and distant sensors will group up with new frigates to create a brand new ‘Atlantic Bastion’, defending the Atlantic from hostile undersea warfare. The primary sensors, Jenkins says, will probably be deployed subsequent yr. Throughout the subsequent two years, Royal Navy USVs will probably be within the water, able to act as uncrewed escorts for manned Kind 26 anti-submarine frigates. One Kind 26 would go to sea patrolling the Atlantic Bastion with two of those escorts, and they’re additionally anticipated to hitch the subsequent Indo-Pacific service strike group deployment.
ASW will hinge across the Bastion Atlantic idea, which incorporates uncrewed varieties, the Kind 92 sloop – primarily a LUSV VDS tug – and the Kind 93 chariot – an XLUUV. These along with wave gliders will ship persistent subsurface surveillance accross the GIUK hole. pic.twitter.com/343d4ytCfS

Deliberate USVs embody the Kind 91, meant as an ‘arsenal ship’ to increase the weapons magazines of Kind 26 frigates and future Kind 83 destroyers, and the Kind 92 ‘Sloop’, an ASW targeted vessel. The Kind 93 will probably be an uncrewed underwater car, or UUV. The Royal Navy’s first giant UUV was launched at HMNB Devonport earlier this yr.
The First Sea Lord notes that “as a result of they don’t have any crew, the escorts will not be complicated vessels, they’re straightforward to provide at scale, even simpler to configure to particular mission necessities as the duty calls for.”
One Manner Effectors
A brand new class of weapon which has emerged into the highlight since DSEI 2023 are a method effectors (OWEs). This time period is basically used to explain small, expendable UAVs which might be fitted with offensive payloads, ISR, or EW gear, very similar to Iran’s notorious Shahed drones.
MBDA launched their CROSSBOW OWE at DSEI 2025, aiming on the vehicle-launched market. CROSSBOW will present a variety of as much as 800 kilometers, with a payload of 300 kilograms. It was designed in parallel with the beforehand launched OWE from this yr’s Paris Air Present.
CROSSBOW could possibly be prepared for frontline service by 2026, and was developed in a remarkably quick timeframe of simply seven months.
MBDA additionally debuted a variant of their Akeron missile designed for launch from 120mm NATO customary smoothbore tank barrels. The Akeron MBT 120 contains an anti-armour warhead, low smoke rocket motor, and AI-enabled focusing on. The missile boasts as much as 1.5 kilometers of efficient vary and, utilizing business off the shelf (COTS) elements is ready to be freed from U.S. imposed ITAR restrictions.
Our reporter on the bottom on the present, Jamie Grey, would additionally prefer to thank MBDA’s representatives at DSEI 2025 on a private foundation for going above and past to offer as a lot clear element about their choices as attainable.
The necessity to defend in opposition to OWEs and different sorts of gentle UAVs was additionally obvious from shows at DSEI. An fascinating electrical jet powered UAV, often called Kestrel, was displayed by UK producer Greenjets. Kestrel is designed to be fielded as a drone interceptor. A model of the plane was beforehand proven off at Farnborough Worldwide Airshow in 2024, however the newer, extra detailed mannequin at DSEI exhibits the design has matured since then.
Quite a lot of counter-drone weapons, together with weapons, missiles, and digital weapons, had been displayed. Many had been proven fielded on board autos, prepared for speedy deployment into trendy battlefields.

DSEI 2025 wraps up on Sept. 12, with extra bulletins more likely to trickle by way of on the ultimate day. There are a lot of extra tales to inform from the exhibition, and rather more to elaborate on from these featured above. Keep watch over The Aviationist for deep dives into these tales and extra.
