An aerospace and technology company recently conducted maiden piloted flight of its full scale prototype aircraft. Vertical Aerospace’s full-scale prototype is expected to accelerate flight testing, support piloted demonstrations and advance Vertical’s hybrid-electric aircraft programme.

The latest prototype will progress through all phases of piloted flight testing, including thrustborne, wingborne and transition flight.

The company also revealed that this is the final prototype before Critical Design Review (CDR), which will establish the certifiable aircraft design and pave the way for assembly of Vertical’s first pre-production aircraft.

New prototype is final aircraft to join Vertical’s flight test fleet

The new prototype is the final aircraft to join Vertical’s flight test fleet before the Company completes Critical Design Review (CDR), a major programme milestone that establishes the design baseline for certification. Following CDR, Vertical will begin preparations for assembly of its first pre-production aircraft as it continues toward certification and commercial service.

“Getting our latest prototype into flight testing is an important milestone because it allows us to learn faster in real world conditions and keep building momentum towards certification,” said Stuart Simpson, CEO of Vertical Aerospace.

“Expanding the flight test fleet will help us validate the aircraft more quickly, reduce risk, and move more efficiently towards bringing Valo into service.”

Latest aircraft doubles Vertical’s flight testing capacity

The company revealed that the latest aircraft doubles Vertical’s flight testing capacity and supports additional public demonstrations this year. Following the completion of all flight test phases – thrustborne, wingborne and transition flight – in its all-electric configuration, Vertical intends to retrofit this prototype for hybrid-electric flight testing.

The hybrid-electric variant is expected to support applications demanding greater range and payload capability across defense, logistics, and wider commercial sectors, according to a press release.

The prototype shares the same configuration as Vertical’s current full-scale aircraft, which has already completed all flight test phases. Vertical’s flight test programme is built around full-scale, piloted prototype aircraft with architecture, systems and flight characteristics closely aligned to the production-standard Valo aircraft, enabling the Company to validate the technologies, systems integration and flight models that will support certification, as per the release.

The new prototype shares the same configuration as Vertical’s existing full-scale aircraft, which has already completed all major flight-test phases. By using full-scale, piloted prototypes that closely resemble the production-standard aircraft, the company aims to validate key technologies, systems integration, and flight models required for regulatory certification.

The latest demonstration marks a significant step toward certification and commercial deployment of the company’s next-generation electric air taxi, Valo.

The Bristol-based company has secured approximately 1,500 pre-orders for the Valo aircraft from customers across four continents. Its customer base includes major aviation and leasing companies such as American Airlines, Avolon, Bristow Group, GOL, and Japan Airlines.

A new type of counter-drone system is set to enhance the defense of the U.S. Army. L3Harris Technologies has received an order to deliver VAMPIRE counter-unmanned systems (c-UxS) to the U.S. Army to support urgent defense against hostile drones.

The VAMPIRE capability delivers advanced reconnaissance and precision strike against drones and remotely piloted aircraft. Military forces have used the technology extensively in support of European combat operations, logging more than 350,000 operational hours since 2023.

Counter-drone systems can be quickly assembled

“We’ve worked with the Army to understand their needs for new counter-UxS systems that can be quickly assembled, delivered, set up and fired,” said Tom Kirkland, President, Targeting & Sensor Systems, Communications & Spectrum Dominance, L3Harris.

“VAMPIRE is effective at hunting and engaging drone threats affordably, which enables U.S. armed forces to sustain reliable defense of its personnel and infrastructure.”

L3Harris developed and invested in VAMPIRE at the beginning of the war in Ukraine to provide a low-cost solution to eliminate Russian drone threats. The company has maintained that the VAMPIRE is an affordable, compact ISR and counter-unmanned-weapon system designed to deploy on nearly any platform, vehicle, or vessel. 

This all-in-one system excels in Counter-small Unmanned Airborne System (C-sUAS) operations, delivering precision strike capabilities with customizable sensors and weapons, significantly reducing the cost-per-effect and overall cost of ownership.

High-volume production of VAMPIRE systems

The Army’s order is worth up to $106 million as part of the United States’ layered c-UxS defense approach.

In March, the company initiated high-volume production of VAMPIRE counter-unmanned systems (C-UxS) in Huntsville, Alabama. The new production line was a direct response to the United States and its allies’ need to combat the persistent drone threat posing risks to military personnel and infrastructure.

The facility features a flexible assembly, testing, and installation area to integrate VAMPIRE onto ground vehicles and containerized weapon systems. The production line can adjust and increase volume as demand evolves.

Building upon the success of the baseline VAMPIRE system, L3Harris has incorporated additional sensor capabilities, precision weapons, electronic jammers, and non-kinetic effectors for use across several domains. The system uses artificial intelligence and machine learning to more swiftly detect, engage, and defeat small, elusive unmanned threats.

The expanded VAMPIRE family of systems now includes multiple specialized variants.

As drone warfare continues to reshape the battlefield, military planners worldwide are prioritizing layered air-defense networks capable of addressing threats ranging from small commercial drones to more advanced unmanned systems. The U.S. Army’s latest investment in VAMPIRE highlights the increasing role of adaptable, rapidly deployable counter-drone technologies in future defense operations.

With production ramping up and operational demand increasing, the VAMPIRE program represents a significant step in strengthening U.S. and allied defenses against one of the fastest-growing challenges in modern military operations.

A German company has showcased its next-generation highly mobile air defense system. Called IRIS-T SLS MK4, the system is specifically designed to protect troops on the move and critical infrastructure from airborne threats.

Developed by Diehl Defence, this fourth generation of the IRIS-T SLS system has an effective range of 7 miles (12 km) and an altitude coverage of up to 3.7 miles (6 km).

The company revealed that the system combines the components radar, C2 system and launcher, including effectors, on one vehicle, making it an “all-in-one” solution. Due to its high mobility and a compact design, the air defense system can be relocated in a very short time.

High degree of automation

Further key features of IRIS-T SLS MK4 are the high degree of automation and the resulting low manpower requirements, which enables extremely fast response times. The vehicle-independent design allows maximum flexibility for different customer demands, according to a press release.

Diehl Defence also revealed that the proven IRIS-T air-to-air missile is used as effector. It remains unchanged in hardware and will enable the “fire-on-the-move” capability in the future – the firing of the missile on the move. The integration of additional effectors, such as the C-UAV eMissile CICADA from Diehl Defence or a weapon station, is also possible.

MK4 version consistently meets NATO standards

The SLS system is already fully integrated into the Diehl Defence concept of multi-layered air defense. The further development and upgrade to the MK4 version consistently meets NATO standards and operational requirements, including an increased payload capacity with an eightfold load and the associated increase in combat effectiveness.

The IRIS-T missile is and remains the core element of ground-based air defense at Diehl Defence, even in the combat-proven SLS system. As an air defense system with future-proof capabilities, IRIS-T SLS MK4 stands for high performance in dynamic threat scenarios.

Another important aspect of the new system is its modularity. The vehicle-independent design allows integration onto different platforms to meet customer requirements. Diehl Defence also stated that additional effectors, including its CICADA counter-unmanned aerial vehicle interceptor and remote weapon stations, can be incorporated into the system, expanding its mission profile beyond conventional air defense.

The unveiling of the IRIS-T SLS Mk4 comes at a time when demand for modern ground-based air defense systems is rising sharply across Europe and other regions. The success of the broader IRIS-T family in operational deployments and growing investment in layered air defense networks have positioned the system as a key component of future NATO and partner-nation air defense architectures.

With its combination of mobility, automation, modularity, and proven missile technology, the IRIS-T SLS Mk4 represents Diehl Defence’s latest effort to provide armed forces with a flexible and rapidly deployable solution for countering evolving aerial threats in an increasingly complex security environment.

Researchers in the United States are studying impact flashes generated by high-speed collisions. It’s being claimed that advances in understanding the optical impact flashes can be highly beneficial for missile defense, making it possible to determine the composition of an intercepted missile and its payload.

Conducted by researchers in Southwest Research Institute (SwRI), the work could also aid scientists in identifying the origins of meteorites or asteroids impacting surfaces, based on their composition.

Energy of the impact creates a flash

“When a meteorite strikes the surface of a moon or planet, the energy of the impact creates a flash that gives off so much energy that the chemical signatures of its constituent materials are visible at different wavelengths,” said Dr. Pablo Bueno, a lead engineer in SwRI’s Mechanical Engineering Division.

Researchers have revealed that the impact flash is a physical phenomenon resulting from conventional and hypervelocity impact. The emission of the flash is related to the composition of the target; thus, spectrographic measurements provide spectral data that could be used to identify the materials involved in the collision, according to the project.

Bueno and Roberto Enriquez-Vargas, an SwRI senior research engineer, recently completed an internally funded SwRI project that developed and refined methods for using high-speed spectroscopy to analyze the light emitted during hypervelocity impacts, where the impact flashes typically only last a few microseconds. The short time window required capturing spectral data quickly and precisely, according to a press release.

Laser-based triggering system

Bueno and Enriquez-Vargas used both of SwRI’s two-stage light-gas guns to create hypervelocity impacts representative of missile strikes or asteroid impacts. The large gun system generates velocities up to 7 kilometers per second (15,660 mph). The system is 22 meters (72 feet) long and traditionally used to study ballistics, as per the release.

Because the impact occurs so swiftly and the flash decays rapidly, Bueno and Enriquez-Vargas developed a laser-based triggering system to precisely detect the instant an impact occurs, accurately measuring impact timing within 100 nanoseconds, or one 10-millionth of a second, according to researchers.

“Thicker targets produced brighter, longer flashes,” Bueno explained. “Higher atmospheric pressure created broader and thicker emission lines in the spectra, and in many cases materials at high temperature behaved differently than they did when impacted at room temperature.”

The team developed and tested laser-based triggering scheme. Accurate timing within 100 ns of the impact was demonstrated.

The team also revealed that the strong lines of the emission spectra of aluminum and copper have been measured and characterized within ±2 nm of their published values. The doublet near 396 nm, for aluminum, and the triple near 515 nm, for copper, have been selected as the best lines to continue with the experimental test matrix.

The effects of projectile flight speed, atmospheric pressure, and atmospheric composition have been documented. These results are fulfilled in part metric 3 of the program. The results show these parameters affect the amplitude and width of the emission lines, according to the project.
