Named One Approach Effectors (OWE), these weapons are ground-launched and able to hitting targets greater than 500km away whereas carrying a strong 225kg warhead.
During the last yr, three British defence corporations, MBDA UK, MGI Engineering, and Rotron Aerospace, have produced new OWE weapons for the Ukrainian navy below a programme named ‘Mission Brakestop’. Every system has now been efficiently check launched main the best way to the subsequent part of the mission wherein £15 million contracts are being awarded for additional improvement of the OWEs.
Every firm will produce 15 improved weapons, alongside plenty of launchers and help automobiles which can be examined extensively. As soon as this has been achieved the three weapons will ultimately start serial manufacturing and for supply to the Ukrainian Armed Forces (AFU) by the top of the yr.
The mission was launched in late 2024 with the requirement for a weapon system that has a spread of not less than 500km (310 miles), a warhead weighing not less than 225kg (round 500lbs), pace of greater than 600km/h (373 mph), a goal unit value of round £400,000 ($526,600) excluding the warhead and the power to provide not less than 20 weapons a month inside months of a manufacturing order.
Not reported within the British authorities’s official assertion on the mission, however reported by the Monetary Instances, is the intention for the weapons to even be freed from US parts and navigation information, permitting the UK to make unbiased sovereign choices on their use by Ukraine. MBDA’s Storm Shadow missile, first gifted to Ukraine in 2024 had been initially delayed of their employment as a result of their use of American parts and steerage information. As a result of US’ extra bellicose angle to Ukraine in latest months, it’s now extra necessary than ever for Ukraine to have weapons which might be politically dependable.
At first of the competitors, 27 bids had been acquired from the UK’s defence trade, with preliminary pitches made to the Ministry of Defence (MOD) in February 2025. Six British corporations had been then awarded contracts price round £5 million every to design and construct prototype weapons for testing that may happen inside seven months. Nevertheless, by December of that very same yr solely the three listed suppliers remained to check fireplace their new weapon methods.
This represents a particularly fast-paced programme which has turn out to be a rarity amongst British defence tasks, with the Ajax armoured automobile programme seemingly indefinitely on pause after an eight yr delay, while the RAF Wedgetail mission continues on after a 3 yr delay. The success of mission Brakestop to this point is a reminder that when pressured British trade can ship top quality weapon methods at scale.
Every weapon system was then examined on the MOD Hebrides Vary, a specialist trials website managed by QinetiQ which is used for giant scale reside fireplace workout routines and navy trials of plenty of British weapons, together with the DragonFire laser system.

The Minister for the Armed Forces Louise Sandher-Jones MP acknowledged:
“The UK stands shoulder-to-shoulder with Ukraine, and we are going to proceed to supply the help it must defend itself in opposition to Russian aggression.
Mission Brakestop exhibits what occurs after we mix that dedication with the expertise and ingenuity of British trade. In lower than a yr, UK corporations have taken an formidable idea from the drafting board to flight testing, delivering a brand new technology of functionality at outstanding pace.
It is a clear demonstration that Britain has the commercial energy, innovation and willpower to fulfill the challenges of contemporary warfare and help our allies.”
What’s a One Approach Effector (OWE)?
A OWE is meant to be a catch-all time period for the varieties of low-cost kamikaze drones rising in recognition all over the world. They sit in a class between cruise missiles and unmanned aerial automobiles (UAV) of their value and firepower, while sharing similarities with each.
Consequently, they are often arduous to correctly outline because the class is by its nature extraordinarily broad. For instance, a Russian/Iranian OWE could be the Shahed 136 kind drone which have been used to focus on Ukrainian cities to overwhelm native air defences with a low value, however harmful munition. Ukraine however has used transformed civilian plane in the same position, packing them with explosives, becoming them with rudimentary steerage kits and a distant management to fly them into Russian territory at a decrease value than a cruise or ballistic missile.
The low value and excessive manufacturing pace of a majority of these methods signifies that each Ukraine and Russia have been in a position to launch large every day air raids in opposition to the opposite, with the variety of weapons employed reaching over 1,000 OWEs at a time. For the US or the UK to make use of the same variety of cruise missiles, they’d deplete total many years price of manufacturing in only a few days. These OWEs permit a nation to have a functionality just like the 1,000 bomber raids of the Second World Battle with only a fraction of the fee.

Each Ukraine and Russia use assault drones that depend on human management from secure territory to fly the weapon to the goal zone, earlier than an AI system constructed into the platform takes management for terminal steerage in opposition to a goal. This ensures that the weapon is ready to keep away from being downed by digital warfare that may normally disable them by disconnecting the pilot to the weapon.
The world of OWEs is now extraordinarily broad, with even small FPV drones hooked up to explosives being included regardless of their small dimension, vary and payload.
MGI Defence describes an OWE as an autonomous or semi-autonomous aerial platform designed for a single-use mission. They’re supposed to be extra versatile than a missile, inexpensive than a reusable drone and sooner to provide than standard missile methods.
However, MBDA describes an OWE as a weapon designed to exhaust an opponent’s assets by exerting fixed strain on their air defence methods, in order that these defences might be detected and neutralised, permitting for costlier lengthy vary weapons to achieve their targets farther inland. MGI Defence prioritises the weapons autonomous steerage methods and its low-cost nature while MBDA makes use of the mission parameters and goal kind to explain what makes an OWE.

The idea behind an OWE is extraordinarily broad and continually evolving because of the continued struggle in Ukraine, which retains the tempo of improvement of those weapons extraordinarily excessive.
MBDA – Crossbow Heavy
MBDA Missile Methods has an extended pedigree of manufacturing superior missile based mostly methods for the British and French militaries, from air-launched cruise missiles, corresponding to Storm Shadow/SCALP-EG, to the ship-launched air defence missiles of the Aster 15 and 30 vary. They’re persevering with to provide excessive value missile methods with the Stratus subsequent technology cruise missiles that can exchange the Storm Shadow/SCALP-EG in British and French service.
The creation of a less expensive various within the OWE class is subsequently an fascinating change of course reflecting the battlefield realities stemming from Ukraine.Their product, the Crossbow OWE Heavy, is designed to be a deep-fires functionality which may function within the advanced digital warfare (EW) setting of Ukraine, at a value that permits important fight mass compared to MBDA’s extra subtle weapons.
On this regard Crossbow is a modular design utilising navy and industrial off the shelf parts which have to this point enabled the speedy improvement of the system which may then be produced at a scale that far outstrips their annual manufacturing of Storm Shadow missiles. The Crossbow is floor launched from the again of a automobile, delivering multi-role kinetic and non-kinetic payloads as much as 300kg out to ranges in extra of 800km.
MGI Defence – Tigershark
The second chosen firm, MGI Defence, is part of MGI Engineering, which has a 25 yr lengthy historical past in producing elements for Method 1 vehicles. ‘Mission Brakestop’ is their first profitable foray into defence although it’s not their solely drone product.
Their flagship OWE is known as the Tigershark, which has a pace of 750 km/h, a 300 kg payload, and it’s able to placing targets at ranges exceeding 1,000 km. This weapon was developed in shut strategic partnership with Auterion, a US agency that produces on board autonomous methods for a technique assault munitions.
Mike Gascoyne, CEO of MGI Engineering, commented:
“The profitable launch of TigerShark is a defining second for MGI. This platform exemplifies our method to engineering excellence—speedy, agile, and mission-focused. Partnering with Auterion has allowed us to combine world-class autonomous capabilities right into a system designed from the bottom up for flexibility and future development. Collectively, we’re delivering an answer that meets right this moment’s wants whereas anticipating tomorrow’s challenges.”
Rotron Aerospace – SkyLance
The ultimate firm forming part of ‘Mission Brakestop’ is Rotron Aerospace, a British enterprise that produces plenty of UAVs of a number of sorts from small quadrotors to its bigger SkyLance OWE. Their space of experience is the skilled use of the Wankel kind rotary engine which permits for an honest output of energy from a comparatively compact engine, making it splendid for gentle automobiles and UAVs.
This enabled Rotron to shortly pivot to producing helicopter kind UAVs following the beginning of the struggle in Ukraine. On account of this, the SkyLance OWE is the one weapon of the three chosen to not use a jet engine for its mid-course propulsion, as a substitute utilizing a wankel engine powered propeller.
The weapon does nonetheless utilise a rocket assisted take off system, a lot in the identical vein because the Tigershark and has a really comparable efficient vary of 1,200km. Nevertheless, its pace is far diminished because of its lack of a jet engine.
All three OWEs are very comparable visually, with minor variations in payload capability, efficient vary and their onboard steerage methods. Given the significance of those deep strike weapons to the Ukrainian navy, it’s probably that each one three can be deployed to Ukraine in giant numbers, as a substitute of the federal government deciding on only one weapon to mass produce. This permits for a variety of weapon methods that the Russian navy need to cope with, while maximising the results on the British defence sector, giving all three corporations a nicely wanted funding increase.

These weapons are however a small a part of the UK’s help for Ukraine below Operation Scorpius, which is the identify given to the MOD’s overarching framework to coordinate navy support, gear, and logistical help for Ukraine following Russia’s invasion. Inside this framework is Taskforce Kindred, a crew of MOD employees who handle the response to requests from the Ukrainians and work with Defence Tools & Assist to develop and procure the required gear. Taskforce Kindred receives common suggestions from Ukrainian forces in regards to the effectiveness of the gear it’s offering, which it considers for future procurement requests.

That is the mechanism by which British trade can perceive the necessities for the AFU in addition to the teachings discovered from the battle with regard to what weapon methods work, which is how the OWE has turn out to be so outstanding of their defence portfolios.
If Ukraine needs to proceed upping its tempo of strikes in opposition to Russia, to realize continuous outcomes just like these seen throughout a latest assault on Moscow, the OWEs these corporations provide can be of maximum significance to the AFU.
