Russia’s UAC Completes Maiden Flight of Su-57D Two-Seat Fighter
Russia’s United Aircraft Corporation completed the maiden flight of the Su-57D two-seat fighter, expanding roles for training and command.

This article is based on an official press release from United Aircraft Corporation (UAC), supplemented by industry research and analysis.
On May 19, 2026, Russia’s United Aircraft Corporation (UAC), a subsidiary of the Rostec State Corporation, successfully completed the maiden flight of the Su-57D. According to an official company press release, this new military aircraft is a two-seat, multirole fifth-generation fighter designed to expand the operational scope of the baseline Su-57 platform.
The prototype was piloted by Sergei Bogdan, Sukhoi Design Bureau Chief Test Pilot and Hero of Russia. Industry data confirms the flight took place at the Gromov Flight Research Institute airfield in Zhukovsky, near Moscow, lasting approximately 40 minutes.
UAC and Rostec officials highlighted that the flight proceeded in accordance with mission requirements, evaluating the stability and handling characteristics of the modified airframe. The introduction of the twin-seat variant marks a significant milestone, introducing a platform intended for combat, advanced training, and airborne command and control.
Technical Specifications and Airframe Origins
According to defense analysts and open-source intelligence cited in our research, the prototype, carrying the side number “055 Blue”, was not a clean-sheet build. Instead, it was converted from an existing single-seat airframe, specifically the T-50-5R. Industry records indicate this original airframe first flew in 2013, suffered an engine fire in 2014, and was subsequently rebuilt.
During the maiden flight, Pilot Sergey Bogdan reported that the aircraft’s performance, stability, and controllability were broadly consistent with the single-seat variant, and all onboard systems operated normally.
Cockpit Configuration and Design
The Su-57D features an elongated cockpit canopy to accommodate a tandem two-seat configuration. Similar to the design philosophy seen in the Su-30 Flanker family, the rear seat is positioned significantly higher than the front seat, providing the second crew member with adequate forward visibility. UAC officially registered the patent for this two-seat design in November 2023, outlining its technical specifications and intended role as an aerial command center.
Strategic Roles: Manned-Unmanned Teaming and Training
The official press release outlines three primary operational roles for the Su-57D: command and control, combat training, and multirole combat. A key function of the second crew member will be to manage mixed groups of manned and unmanned aircraft.
“The two-seat version of the Su-57… can be used not only for pilot training but also for organizing and managing combat operations of a joint group of manned and unmanned aircraft, creating a unified information and control space,” stated Rostec in the official release.
The “Loyal Wingman” Concept
Defense analysts note that this command-and-control capability aligns closely with Russia’s ongoing development of the S-70 Okhotnik (“Hunter”) heavy stealth drone. The Su-57D is expected to act as an airborne command center, directing the S-70 as a “loyal wingman” in highly contested airspace.
“This aircraft, developed proactively by our aircraft manufacturers, will not only boast unique combat capabilities but also the capabilities of a combat trainer and combat control aircraft,” noted First Deputy Prime Minister of Russia Denis Manturov in the UAC release.
Like the baseline Su-57, the Su-57D retains its low-observability characteristics and is capable of engaging air, ground, and naval targets around the clock, even in adverse weather and heavy electronic jamming environments.
Export Potential and Global Context
Beyond its tactical applications for the Russian Air-Forces, the Su-57D is heavily geared toward the export market. Historically, Russian twin-seat fighters have been highly sought after by foreign clients, and UAC leadership explicitly linked the new configuration to international sales.
“We continue to work on improving and expanding the functionality of our most advanced fifth-generation aviation system. I am confident that the two-seat version of the aircraft will significantly contribute to its success in international markets,” said Vadim Badekha, CEO of UAC.
Prospective International Clients
Industry reports indicate that India and Algeria are primary prospective buyers. Talks between Russia and India regarding the license production of the Su-57 are reportedly at an advanced technical stage. Sukhoi had previously drafted a two-seat version specifically for an Indian requirement under the now-suspended joint Fifth Generation Fighter Aircraft (FGFA) program.
Globally, the introduction of the Su-57D places Russia alongside China, which has developed the J-20S, a two-seat version of its own fifth-generation stealth fighter. In contrast, the United States currently does not operate a two-seat fifth-generation fighter, as neither the F-22 nor the F-35 features a twin-seat variant.
AirPro News analysis
We observe that converting an existing prototype (Tail 055) rather than manufacturing a new airframe from scratch is a pragmatic, cost-effective practice in military aviation testing. This approach allows UAC to accelerate the aerodynamic and systems testing of the tandem cockpit without the lead time required for a new build. Furthermore, the explicit focus on manned-unmanned teaming underscores a global shift in aerial warfare doctrine, where fifth-generation fighters are increasingly viewed as central nodes in a broader network of autonomous combat vehicles.

AEVEX Corp Unveils Specter Modular Autonomous Attack Platform
AEVEX Corp announced Specter, a turbojet-powered autonomous one-way attack system built with Divergent Technologies.

AEVEX Corp. (NYSE: AVEX) announced the development of Specter, a modular, turbojet-powered autonomous platform designed for contested environments, on September 23, 2026. The new one-way attack system, developed in collaboration with advanced manufacturing company Divergent Technologies, expands the company’s Unmanned Aircraft Systems (UAS) portfolio.
According to a press release issued by AEVEX, the platform leverages Divergent’s digital manufacturing capabilities to allow rapid iteration and payload integration without requiring full system redesigns. The platform remains under development, and AEVEX has not provided a specific timeline for deployment or pricing information.
Technical capabilities and manufacturing approach
Specter integrates directly with AEVEX’s existing CompassX autonomy architecture. The platform is designed to be highly adaptable, featuring a swappable nose section and variants configured for both ground and air launches. The design targets high-speed operations in contested operational environments where flexibility is required.
The manufacturing process utilizes the Divergent Adaptive Production System (DAPS). This approach is intended to enable scalable production and quick adjustments to the aircraft’s physical design based on evolving mission requirements.
Manan Patel, Chief Technology Officer at AEVEX, stated that the system reflects lessons learned from delivering thousands of autonomous systems in theater.
“We are not optimizing for a fixed requirement, we are building an architecture that adapts. Specter is designed to evolve with mission demands, payload technologies…”
Recent defense contracts and financial context
The announcement of the Specter platform follows a series of recent defense contracts awards for AEVEX. On September 16, 2026, the company was selected for a SkyRange contract valued at up to $92.2 million to support hypersonic testing. Prior to that, on September 9, 2026, AEVEX secured $20.5 million in new awards specifically to deliver and advance one-way attack systems.
AEVEX completed its Initial Public Offering (IPO) in April 2026. The company is currently facing investor-solicitation notices regarding a pending securities class action lawsuit related to the IPO. Law firms allege that disclosures misled investors concerning a waiver of a 180-day lock-up period 41 days after the public offering. The deadline for investors to seek lead-plaintiff status is October 20, 2026. The allegations remain unproven, and the current notices are investor solicitations that do not establish that the company violated securities laws.
AirPro News analysis
We note that the introduction of Specter aligns with a broader aerospace industry shift toward modular, rapidly producible autonomous systems. By partnering with Divergent Technologies, AEVEX is attempting to bypass traditional, slow-moving aerospace manufacturing bottlenecks. The emphasis on a swappable architecture suggests a strategic focus on adaptability in electronic warfare and contested airspace, where payload requirements change rapidly.
The backdrop of the pending securities litigation introduces a layer of complexity for the newly public company. While the recent $112.7 million in combined contract awards demonstrates continued operational momentum and government trust, AEVEX will need to navigate its post-IPO legal challenges while executing the development and fielding of the Specter platform.

RAF Activates No. III Space Effects Squadron for Orbital Defense
The UK RAF launched its first active orbital defense unit, backed by £880M in space control funding through 2029/2030.

The Royal Air Force (RAF) has officially activated No. III Space Effects Squadron, marking a strategic shift for the United Kingdom from passively monitoring orbital threats to actively defending its critical satellite infrastructure.
Announced on September 23, 2026, at the inaugural UK Space Power Conference in London, the new unit is the first of its kind for the UK military. According to an RAF press release, the squadron will utilize advanced technologies, including electronic warfare, to disrupt, degrade, and deny hostile actions against British satellites. These orbital assets are essential for guiding maritime navigation, connecting mobile networks, and supporting early missile warning systems.
Strategic shift in orbital defense
The formation of No. III Space Effects Squadron completes a specialized triad within the RAF space command structure. It complements the existing No. I Space Operations Squadron and No. II Space Warning Squadron, which are primarily tasked with tracking orbital assets and identifying potential threats. The new unit transitions the military posture toward active deterrence and defense.
“Space no longer supports operations from the sidelines. It is a domain of direct competition, where our military advantage can be won or lost. No. III Space Effects Squadron will safeguard the vital benefits that space gives to our integrated armed forces, and will be capable of denying those benefits to our adversaries,” stated Air Chief Marshal Sir Harv Smyth, Chief of the Air Staff.
The squadron will operate under the broader umbrella of UK Space Command, integrating its electronic warfare capabilities with existing intelligence and surveillance networks to protect both offensive and defensive space operations.
Funding and the UK Space Strategy
The squadron launch aligns with the updated UK Space Strategy published by the government on September 8, 2026. The strategy commits £7.8 billion to the domestic space sector through 2030, placing national security and defense at the center of the policy. Within this framework, £880 million is specifically allocated between the 2026/2027 and 2029/2030 financial years for space-based intelligence, surveillance, reconnaissance, and space control activities.
Speaking at the conference, Defence Secretary Wes Streeting emphasized the historical context of the new domain and the necessity of the investment.
“Britain has to keep pace in the new space race. Control of the waves was the essential ingredient in 19th century deterrence. That is why Britain built the finest naval power in history. In the 20th century it was control of the skies, and so we built a world class air force to protect us,” Streeting said.
Streeting added that the dependency on space infrastructure makes it a growing target for adversaries. He noted that challenges in orbit increasingly mirror terrestrial geopolitics, requiring the UK Ministry of Defence (MoD) to modernize its armed forces to deter and defeat threats in any domain.
AirPro News analysis
The activation of No. III Space Effects Squadron represents a necessary maturation of the UK military space apparatus. As reliance on satellite constellations for secure communications, precision navigation, and early warning systems deepens, the ability to actively protect these assets becomes non-negotiable. By explicitly naming electronic warfare and the capability to deny benefits to adversaries, the MoD is signaling a readiness to engage in non-kinetic orbital defense. We view this development as a clear indicator that European and NATO-aligned forces are accelerating their Space-Agencies control capabilities to match the rapid advancements demonstrated by rival nations in recent years.

Embraer Delivers First C-390 Millennium to Uzbekistan Air Force
Embraer handed over the first of two C-390 Millennium transports to Uzbekistan on Sept 25, 2026, marking the type’s Central Asia debut.

Embraer delivered the first of two C-390 Millennium military transport aircraft to the Uzbekistan Air Force on September 25, 2026, marking the platform’s entry into the Central Asian market. The handover took place at the manufacturer’s facility in Gavião Peixoto, São Paulo, Brazil.
In a press release issued to mark the delivery, Embraer confirmed the aircraft will modernize Uzbekistan’s military airlift capabilities. The C-390 Millennium is slated to replace the country’s legacy Soviet-era transport platforms, taking on roles that include logistics, aerial delivery, and humanitarian relief operations.
Airframe reassignment and production history
The specific aircraft delivered to Uzbekistan bears registration UK39010 and Manufacturer Serial Number (MSN) 39000019. According to reporting by Air Data News, the airframe has a unique production history. It was originally allocated to the Brazilian Air Force (Força Aérea Brasileira) as FAB 2861.
The airframe became available for export reassignment following a November 2023 agreement between Embraer and the Brazilian government. That agreement reduced Brazil’s total C-390 order from 22 to 19 aircraft, down from an initial commitment of 28.
Uzbekistan originally signed a contract for two C-390 aircraft in December 2024 as an undisclosed customer. Embraer officially revealed the buyer at the Singapore Airshow on February 3, 2026. The aircraft completed its first flight from Gavião Peixoto on August 6, 2026, using the test registration PT-CYQ, before being publicly presented in full Uzbekistan Air Force livery on September 10, 2026.
Expanding international footprint and capabilities
The C-390 Millennium features a maximum payload capacity of 26 metric tons and a maximum cruise speed of 470 knots. These specifications position the twin-engine jet as a direct competitor to established turboprop transports in the tactical airlift segment.
The delivery to Uzbekistan represents continued export momentum for the C-390 program. Embraer has secured a series of international selections and orders in recent years. In August 2026, Colombia acquired the KC-390 Millennium variant. Other nations that have selected the platform include Sweden, South Korea, Austria, the Czech Republic, and the Netherlands.
Embraer highlighted the regional significance of the handover during a presentation earlier in the month, as reported by Janes.
“Today, Embraer presents the first C-390 Millennium aircraft of the Uzbekistan Air Force, making the Republic of Uzbekistan the first C-390 customer in Central Asia.”
AirPro News analysis
We view the delivery of MSN 39000019 as a strategic win for Embraer’s defense division, demonstrating the manufacturer’s ability to pivot production slots efficiently. By reallocating an airframe originally destined for the Brazilian Air Force, Embraer accelerated the delivery timeline for a new international customer. This agility is critical as the company works to capture market share from aging Soviet-era fleets like the Antonov An-12 and An-32, as well as Western platforms like the Lockheed Martin C-130 Hercules. Securing a foothold in Central Asia also opens potential avenues for further regional sales as neighboring air forces evaluate their own modernization requirements.
