UK Ministry of Defence Advances Watchkeeper Drone Replacement with 2027 Delivery Target
The UK Ministry of Defence commits £310 million to procure 24 new uncrewed aerial systems by 2029, aiming to retire the Thales Watchkeeper drone fleet by March 2027.
The gist
UK MoD accelerates Project Corvus to field 24 next-gen UAVs by 2027, replacing Watchkeeper drones with nearly doubled budget.
The United Kingdom's Ministry of Defence (MoD) has reaffirmed its commitment to field a successor to the ageing Thales Watchkeeper WK450 surveillance drones by March 2027. This announcement clarifies previous ambiguity surrounding the procurement timeline, as the Watchkeeper platform, based on the Elbit Systems Hermes 450, is scheduled for retirement next year after over a decade of service. The replacement effort is formally known as Project Corvus and represents a major investment in the army's long-range reconnaissance capabilities.
Originally, the Watchkeeper fleet was to be retired in March 2025 with its successor procured by that date. However, due to delays, this schedule has been pushed back, triggering a rapid acquisition push to avoid any capability gaps. Project Corvus now has an allocated investment of £310 million, nearly doubling the initial budget of £156 million, reflecting an expanded scope and the need for a modern, technologically advanced system.
The MoD specifies that under Project Corvus, 24 new uncrewed aerial vehicles (UAVs) will be delivered by 2029 to replace the legacy Watchkeeper fleet. The UAVs will provide 24-hour persistent surveillance, a critical land tactical capability for the British Army. The procurement requires platforms that are deployable, high readiness, easily supportable, and cost-effective, with built-in technological agility to sustain spiral development for evolving mission demands.
Tender documents published in August 2025 outlined an anticipated selection of the new UAV platform by March 2026 and contract commencement in May for an initial five-year period. Despite delays and scarce public updates from the MoD, these proceedings remain active, debunking speculation that the project was shelved. The government’s Defence Investment Plan released on 30 June explicitly includes the Project Corvus funding and timeline, underscoring its ongoing priority.
Currently, the Joint Aviation Command is managing two units of action comprising air vehicles and ground control stations to sustain Watchkeeper operations until September 2026. Post that point, the force will downsize to a single unit of action until the full withdrawal of Watchkeeper drones in March 2027. The MoD has clarified that no further extensions are planned for the Watchkeeper beyond this date, placing pressure on a timely Corvus rollout.
The Watchkeeper unmanned system has been deemed technologically surpassed, with its 46 operational air vehicles described as 14 years old. This obsolescence has driven the urgent demand for next-generation UAVs capable of meeting modern tactical reconnaissance requirements. Project Corvus must therefore deliver a minimum deployable capability before the Watchkeeper exit to maintain continuous surveillance support for operations.
Market engagement for Corvus began in May 2025, seeking industry solutions that meet stringent criteria for rapid deployment, lifecycle affordability, and adaptability to future technological enhancements. The MoD’s outlined requirement emphasizes an agile acquisition approach to integrate advancements and accommodate evolving operational needs without extended procurement cycles.
Thales currently holds the contract to keep Watchkeeper air vehicles operational until March 2027 but is not slated for further contract extensions. The successor programme represents a strategic pivot towards more capable and maintainable uncrewed sector assets, ensuring the British Army's reconnaissance capacity remains robust into the coming decade.
The delivery of 24 new UAVs through Project Corvus will significantly reshape the British Army’s aerial surveillance posture. This procurement signals the MoD's heightened focus on versatile unmanned systems tailored to meet growing operational challenges, all while mitigating the risk of capability gaps during the transition from legacy systems to modern technologies.

United Airlines expands Denver training center adding 40 new CAE flight simulators
United Airlines has completed the first phase of an expansion at its Denver Flight Training Center after adding 40 new CAE flight simulators. The additions include a combination of full-motion flight simulators and fixed training devices. United now operates 52 full-motion simulators and 34 fixed devices at the training center, which the airline describes as the largest pilot training facility in the world. The 22-acre campus in Denver's Central Park neighborhood includes eight buildings and nearly 700,000 square feet of training space. United said it can train as many as 860 pilots per day and conduct more than 32,000 training events annually. The center operates around the clock for 362 days each year. It is United's only pilot training facility, serving nearly 18,000 active pilots as well as newly hired flight crews. United pilots complete simulator sessions during initial qualification and return to Denver for recurrent training every nine months. "This expansion reflects the strength of a partnership built over more than four decades," CAE President and CEO Matthew Bromberg said. "We're proud to support United with the training technology, expertise and reliability needed to prepare pilots at scale." United opened a new 150,000-square-foot building at the campus in 2024 as part of the expansion. The airline invested more than $145 million in the facility, which was designed to accommodate additional full-motion simulators, fixed training devices, classrooms and support areas. The project, which kicked off in 2022, has created more than 300 additional jobs at the training center. United said approximately 1,600 of its more than 11,400 Denver-based employees now work at the training center in positions including flight instruction, evaluation, scheduling, pilot hiring and flight standards. United has invested $370 million in the campus since 2016. The training center was originally constructed between 1966 and 1968 as part of the former Stapleton Airport complex and has served as the airline's main pilot training facility since then. The airline is already preparing for another expansion near Denver International Airport (DEN). Denver City Council approved a rezoning request in July 2026 for two parcels of undeveloped land that United purchased in 2023. United expects to begin construction on the next phase in 2027 and place the additional training facility into operation by 2030. It will operate alongside the existing Central Park campus. The airline has hired more than 9,500 pilots since announcing its United Next growth strategy in 2021. It added approximately 700 pilots during the first part of 2026 and plans to hire hundreds more before the end of the year. United also operates its Aviate pilot career program, the United Aviate Academy in Goodyear, Arizona, and a pathway for active-duty US military pilots. The airline said nearly 600 military pilots have joined United through that program since 2024, with another 500 expected to make the transition by the end of 2027.
Whisper Aero's Ultra-Quiet Electric Engines Power First Piloted Flights in Tennessee
An electric aircraft engine designed to reduce operational noise to a whisper is now powering piloted aircraft. Whisper Aero on Wednesday revealed that its "ultra-quiet" eQ250 electric ducted fan propulsion system is being put to the test in Tennessee under an FAA special airworthiness certification. The company said it installed a pair of eQ250s on a modified Aériane Swift 3 glider, with which test pilot Zac Majors conducted three flights spanning 130 minutes, or about 43 minutes on average. Majors said the aircraft, which the company refers to as the Whisper Powered Swift, produced more thrust and was quieter than the standard propeller version of the glider, "but still great handling." "[I] could really do whatever I wanted with it," Majors said in a statement. "Look forward to flying it again." Fortunately for him, the campaign is only just beginning. Whisper plans to continue testing the Swift in Tennessee before advancing to flight tests and evaluations with "government customers" later this year. The company is under contract with the U.S. Air Force to develop a new family of quiet, efficient, autonomous aircraft for contested logistics, with initial testing planned for 2027. How It Works The eQ250 is the flagship product of Whisper's electric quiet (eQ) engine series. According to the company, it produces up to 85 pounds of static thrust for fixed-wing aircraft. It can also power Group 3 uncrewed aircraft systems (UAS)—which have maximum weight of 1,320 pounds and speed under 250 knots—or larger drone platforms. The specialized electric ducted fans are 10 inches in diameter and produce about 20 dB less noise than "comparable quiet propulsion systems," while also being 20 percent more efficient, according to Whisper's website . For short takeoff and landing (STOL) aircraft, the eQ250 is designed to enable coefficients of lift as high as 14. The propulsion system is intended to unlock short-to-medium-range regional air mobility services using small airports. The idea is similar to Electra's concept for "direct aviation," which involves the company's "ultra-short" takeoff and landing EL9. The goal is to replace trips that would take about 90 minutes driving with air service that takes closer to 20 minutes. Whisper said the Swift's 26:1 lift-to-drag ratio made it ideal for evaluating handling qualities and the propulsion system's performance, integration, and acoustics. Video: Whisper Aero The glider's eQ250s are powered by five Epic 1.0 Energy modules from Whisper partner Electric Power Systems (EPS). According to EPS, they provide 60 minutes of usable flight time with 30 minutes of reserve for trainer, eVTOL (electric vertical takeoff and landing), and "thin-haul" aircraft, which are used for very short trips with a handful of passengers. Whisper said the aircraft "completed its planned objectives," which included validating its propulsion integration, battery, control, and other systems. At full throttle at 100 feet agl, Whisper said the engines were quieter than the airframe itself. Ian Villa, co-founder and chief operating officer, told The Air Current that the glider can generate substantial noise without engines. Flown during the early morning, the aircraft produced about 52 dB(A) of noise compared to 34 dB(A) background noise, Whisper said. "The ability to fly within the soundscapes of even rural environments…will be critical for flights of FAA MOSAIC aircraft," the company added. The Modernization of Special Airworthiness Certification (MOSAIC) took effect in phases over the past few months and permits electric propulsion systems in the light-sport aircraft (LSA) category. More to Come Whisper said the test campaign "reduces risk" for the eQ250's larger civil and defense applications. The company is developing its JetFoil integration for STOL and VTOL aircraft, designed to enable runway independence. The JetFoil distributes ducted fan engines across the entire leading edge of the wing and would enable near-vertical takeoffs with 50 feet of ground roll. Whisper claims it will do so using half the thrust of tilt-rotor VTOL aircraft while offering more range and double the payload. Villa earlier this year told FLYING that Whisper is in talks with government customers to build and fly JetFoil-equipped prototypes, the idea being that they could be transitioned to commercial manufacturers who could bring them to market. For example, one could swap the de Havilland Twin Otter's high wing for a JetFoil and hybrid-electric powertrain. Whisper said the testing will further support its Collaborative Logistics Aircraft (CLA) program with the U.S. Air Force. The CLA concept is similar to the service's Collaborative Combat Aircraft (CCA) framework, which pairs crewed fighter jets with uncrewed "loyal wingmen." Instead, CLA aircraft would carry between 500 and 3,000 pounds of cargo and operate from austere or degraded runways. Whisper is studying two CLA concepts that incorporate 12 and 30 eQ250 engines on the leading edge of the wing, using the JetFoil integration. According to the company, at 250 knots, the CLA aircraft would generate reduced noise and heat signatures compared to models they could replace. Whisper in May 2025 said that initial CLA flight testing would begin in 2027 at White Sands Missile Range in New Mexico. The company has also shared concepts for a regional Whisper Jet and more robust 100-seat model, both based around its ducted fan and eQ technology.
