United Aircraft Corporation Completes 2025 Su-35S Delivery Program with Record Output

The United Aircraft Corporation (UAC), a division of the state-owned defense conglomerate Rostec, has officially concluded its 2025 production program for the Su-35S multirole fighter. According to company announcements released in late December, the Komsomolsk-on-Amur Aviation Plant (KnAAZ) delivered its seventh and final batch of the year to the Russian Aerospace Forces (VKS).

This delivery marks a significant escalation in production tempo. UAC officials and state media have characterized 2025 as a “record-breaking year” for the facility. The delivery of seven distinct batches represents a substantial increase compared to 2024, which saw only four batches delivered. This surge suggests that the manufacturer has successfully adapted its supply chains to meet the high-intensity demands of the ongoing conflict in Ukraine.

While specific airframe numbers are rarely disclosed in full, industry data estimates the total 2025 output to be between 14 and 21 aircraft, assuming standard batch sizes of two to three jets. This brings the estimated total operational fleet of Su-35S fighters to approximately 155 units.

Production Surge and Industrial Resilience

The completion of the 2025 schedule highlights a shift in the Russian defense industry toward a sustained wartime footing. According to UAC, the deliveries occurred steadily throughout the year, with batches handed over in March, May, June, August, September, November, and December. This consistent stream contrasts with the more episodic delivery schedules seen in previous years.

Vadim Badekha, CEO of UAC, emphasized the stability of the production lines in a statement accompanying the release.

“Plants are consistently increasing the output of in-demand combat equipment… the 2025 plan was fulfilled ahead of schedule in some facilities.”

Technical Configuration and Upgrades

The aircraft delivered in 2025 retain the core “Generation 4++” characteristics of the Su-35S but reportedly feature specific enhancements tailored for the current combat environment. According to verified data regarding the delivery program, the 2025 batches are integrated with the R-77M (Izdeliye 180) long-range air-to-air missile.

This weapon system utilizes an active electronically scanned array (AESA) seeker, which offers a higher probability of intercept against maneuvering targets compared to previous iterations. The aircraft continue to utilize the Irbis-E passive electronically scanned array (PESA) radar and AL-41F1S turbofan engines with thrust vectoring, ensuring high maneuverability.

In official releases, UAC has cited feedback from VKS pilots currently operating the platform.

“Pilots describe the aircraft as ergonomic, comfortable, and highly reliable, with a proven combat record.”

AirPro News Analysis: Strategic Implications

The data indicates a clear strategic prioritization of “sortie density” over experimental modernization. By focusing on the mature Su-35S platform rather than exclusively accelerating the production of the fifth-generation Su-57, the Russian defense industry is prioritizing immediate availability to offset combat attrition.

We observe that the Su-35S remains the primary air-superiority asset for the VKS in the Ukraine theater. Its roles have expanded to include:

  • Air Dominance: Engaging hostile aircraft at long ranges.
  • Escort Missions: Protecting Su-34 bombers conducting glide-bomb strikes.
  • SEAD Operations: Suppressing enemy air defenses with anti-radiation missiles.

The 50% increase in batch deliveries year-over-year signals that despite economic pressure, the industrial base is currently capable of replacing losses at a rate that sustains operational pressure on the front lines.

2026 Outlook and Export Constraints

Looking ahead, UAC has confirmed that work on the 2026 production program is already in progress. However, the allocation of these future airframes remains a subject of industry debate. While domestic demand remains high, KnAAZ faces competing obligations from international customers.

Confirmed orders from Iran and Algeria may absorb a significant portion of the plant’s capacity over the next 12 to 24 months. Analysts warn that domestic deliveries to the VKS could potentially decrease in 2026 as the manufacturer attempts to balance urgent wartime requirements with long-standing export contracts. Furthermore, the intense production schedule is straining the workforce, prompting UAC to actively recruit personnel to fill labor gaps.

Lockheed Martin Advances Vectis Drone Program with Key Propulsion Milestone

Lockheed Martin Skunk Works® has announced a critical development in its autonomous systems portfolio, selecting the Williams International FJ44-4 turbofan engine to power the Vectis prototype. This milestone marks a significant step forward for the company’s internally funded “loyal wingman” project, which aims to deliver a high-performance, stealthy uncrewed aerial system (UAS) capable of operating alongside fifth-generation fighters like the F-35.

The announcement, described by the company as “powering up” the prototype, clarifies the Propulsion strategy for the aircraft. While Lockheed Martin is a known leader in directed energy systems, the company confirmed that this specific milestone refers to the integration of the jet engine rather than a laser weapon payload. The Vectis program represents a strategic pivot for the defense giant as it targets the upcoming “Increment 2” of the U.S. Air Force’s Collaborative Combat Aircraft (CCA) program and international defense markets.

Technical Specifications and Propulsion

According to the press release, the selection of the Williams International FJ44-4 engine was driven by a need for reliability and speed in development. The FJ44-4 is a commercially proven turbofan engine, widely used in business jets, which offers approximately 3,600 pounds of thrust. By utilizing a mature commercial engine, Skunk Works aims to reduce technical risk and accelerate the flight testing timeline.

Peter McArdle, Integrated Systems Program Director at Lockheed Martin, emphasized the strategic value of this choice in the company’s statement:

“By leveraging a mature, rugged turbofan, we can accelerate our timeline and demonstrate a game-changing capability quickly.”

Performance Capabilities

The Vectis prototype is designed as a Group 5 UAS, a classification for large, high-altitude Drones. The aircraft features a “lambda wing” tailless design and utilizes advanced composite materials to achieve what Lockheed Martin describes as “best-in-class” low observability (stealth). Key performance metrics released by the company include:

  • Speed: High subsonic (estimated Mach 0.8 – 0.85), designed to keep pace with crewed fighters.
  • Range: Greater than 1,000 nautical miles, specifically tailored for the vast distances of the Indo-Pacific theater.
  • Endurance: Four or more hours of flight time.
  • Timeline: First flight is scheduled for 2027.

Strategic Context: The CCA Competition

The development of Vectis occurs against the backdrop of the U.S. Air Force’s Collaborative Combat Aircraft (CCA) competition. In April 2024, the Air Force selected Startups Anduril and General Atomics for the first round of the program, bypassing traditional prime contractors like Lockheed Martin. In response, Skunk Works has chosen to internally fund the Vectis program rather than wait for a government contract.

Lockheed Martin is positioning Vectis as a “high-end” alternative to the more “expendable” drones currently being prioritized. The platform is designed with an open systems architecture, allowing for the integration of third-party software and payloads, a direct response to government demands for modularity and the avoidance of vendor lock-in.

OJ Sanchez, Vice President and General Manager of Lockheed Martin Skunk Works, highlighted the broader vision for the platform:

“We’re not simply building a new platform – we’re creating a new paradigm for air power based on a highly capable, customizable and affordable agile drone framework.”

AirPro News Analysis

The “Attritable” vs. “Survivable” Debate

Advertisement

The Vectis program highlights a central debate in modern aerial warfare: the trade-off between cost and survivability. While the initial round of the CCA program favored lower-cost, “attritable” systems that commanders might be willing to lose in combat, Lockheed Martin is betting that peer conflicts, specifically against adversaries with advanced air defense systems, will require more robust, stealthy platforms.

By targeting “Increment 2” of the CCA program, Lockheed appears to be wagering that the Air Force’s requirements will shift back toward higher performance and survivability once the limitations of cheaper drones are fully understood. Furthermore, the focus on F-35 compatibility suggests a strong play for international export markets, where allies operating the Joint Strike Fighter (such as the UK, Australia, and Japan) will require autonomous wingmen that match the stealth profile of their crewed fleets.

Frequently Asked Questions

Does the “Powering Up” headline mean Vectis has a laser weapon?
No. The phrase refers to the selection of the turbofan engine for propulsion. While the aircraft has an open architecture that could theoretically support various payloads, the current announcement is strictly about the flight engine.

When will the Vectis drone fly?
Lockheed Martin has set an aggressive timeline, with the First-Flight scheduled for 2027.

Is the U.S. Government funding this project?
Currently, the project is internally funded by Lockheed Martin. The company is developing the prototype independently to demonstrate capability for future U.S. and international contracts.

What weapons can Vectis carry?
The aircraft features a modular payload bay designed to carry air-to-air missiles (such as the AIM-120 AMRAAM), small diameter bombs, or sensors for intelligence, surveillance, and reconnaissance (ISR) and electronic warfare.
