BAE Systems Secures $11 Million Contract to Upgrade KF-21 Fighter

BAE Systems has officially announced an $11 million contract award from Korea Aerospace Industries (KAI) to supply advanced Identification Friend or Foe (IFF) systems for the KF-21 Boramae fighter aircraft. According to the company’s statement released on December 15, 2025, the agreement involves the integration of the AN/APX-127(V)1 Combined Interrogator Transponder (CIT), a critical avionics component designed to enhance the indigenous fighter’s interoperability and situational awareness.

The contract underscores the deepening industrial cooperation between the British multinational defense contractor and South Korea’s aerospace sector. As the KF-21 program moves through its production phases, the integration of NATO-standard identification systems ensures the aircraft can operate seamlessly alongside U.S. and coalition forces. BAE Systems confirmed that production and delivery of the units are scheduled for 2026, with work being performed at its facilities in Greenlawn, New York, and Austin, Texas.

Technical Specifications and Capabilities

The centerpiece of this contract is the AN/APX-127(V)1 CIT, which BAE Systems describes as a “drop-in” replacement for the AN/APX-126(V) currently used on KF-21 prototypes. This compatibility allows KAI to upgrade the aircraft’s avionics suite without requiring significant structural modifications, streamlining the integration process for the production block.

Advanced Identification Standards

According to the press release, the new system is Mark XIIB certified, meeting the latest U.S. Department of Defense and NATO standards. The system features Mode 5 and Mode S capabilities:

  • Mode 5: This standard utilizes modern cryptographic techniques to provide secure, encrypted identification, significantly reducing the risk of friendly fire (fratricide) and improving resistance to jamming or spoofing in contested electronic warfare environments.
  • Mode S: This mode facilitates interoperability with civil air traffic control systems, allowing for selective interrogation and reducing radio frequency congestion in crowded airspace.

Situational Awareness Upgrades

Beyond basic identification, the AN/APX-127(V)1 includes Automatic Dependent Surveillance–Broadcast (ADS-B) “In” capability. This feature allows the KF-21 to passively receive position and flight data from other aircraft, thereby enhancing the pilot’s situational awareness without the need to emit active signals that could compromise the aircraft’s location. The system also utilizes multi-channel reception to passively acquire Mode 5 Level 2 data, further aiding in the rapid classification of friendly forces.

“The APX-127 Combined Interrogator Transponder will equip the KF-21 aircraft with state-of-the-art IFF to help bolster the Republic of Korea’s national defense strategy. This new system gives fifth-generation fighter pilots an edge in air superiority missions and allows them to maintain interoperability with U.S. and coalition partners.”

— Seth Guanu, Combat Identification Products Program Area Director, BAE Systems

Strategic Context: The KF-21 Program

The KF-21 Boramae is South Korea’s 4.5-generation multirole fighter, developed to replace the Republic of Korea Air Force’s (ROKAF) aging fleet of F-4 Phantom II and F-5 Tiger II aircraft. While the aircraft is indigenous, it relies on select international partnerships for critical subsystems, such as the IFF technology provided by BAE Systems.

With mass production reportedly beginning in mid-2024, the of these upgraded IFF systems in 2026 aligns with the operational fielding of the initial production blocks. The adoption of an open-system architecture in the AN/APX-127(V)1 is intended to facilitate future software upgrades, mitigating obsolescence risks and reducing long-term lifecycle costs for the ROKAF.

AirPro News Analysis

The selection of the AN/APX-127(V)1 highlights a critical requirement for modern non-stealth and semi-stealth fighters: coalition interoperability. While the KF-21 is a South Korean platform, its primary strategic utility lies in its ability to integrate into a broader defensive network involving U.S. assets. By securing Mark XIIB and Mode 5 certification, KAI is ensuring that the KF-21 can participate in complex joint operations without being a liability in the identification chain.

Furthermore, the “drop-in” nature of this upgrade illustrates a prudent engineering approach. Avoiding airframe modifications to accommodate new avionics preserves the program’s schedule and budget, both of which are often volatile in domestic fighter programs. This contract reinforces BAE Systems’ foothold in the Asian defense market, positioning it as a key supplier for the region’s growing fleet of indigenous platforms.

Neura Defense Systems Rebrands as Volantyx Aerospace

Neura Defense Systems rebrands as Volantyx Aerospace to develop counter-UAS tech targeting RF-silent drone swarms.

Published

on

Saint Petersburg, Florida-based Neura Defense Systems, Inc. announced on August 26, 2026, that it has rebranded as Volantyx Aerospace, Inc. to reflect its expansion from a single-product defense developer into a broader aerospace technology platform.

In a press release issued Wednesday, the company stated the original Neura Defense Systems name will be retained for its defense division and current operating business. The corporate restructuring aligns with the company’s focus on developing a distributed edge-intelligence architecture designed to counter autonomous, radio-frequency-silent drone swarms.

Addressing the RF-silent swarm-drone gap

Volantyx Aerospace is targeting a specific vulnerability in current counter-Unmanned Aircraft Systems (UAS) defense networks. Traditional detection and mitigation rely heavily on radio frequency (RF) signals, which are ineffective against pre-programmed or autonomous aircraft that do not emit such signals.

Founder and Chief Executive Officer Sam Talari explained the limitations of legacy systems in the company’s announcement, noting that the new architecture is built on the assumption that any single sensor can be degraded or absent.

An RF sensor cannot detect a signal that is not there, and a jammer cannot sever a control link that does not exist. We start from the aircraft’s physical signature instead — radar return, sound, heat, visual — and combine those into one track and one decision picture for the operator.

The company has filed 13 United States provisional patent applications covering multi-modal sensor fusion, distributed networking, cognitive command, and the detection of non-emitting aircraft. The resulting intelligence layer is designed to make decisions at the edge without cloud dependency while preserving a record of system observations.

Development timeline and market positioning

The rebranding occurs as federal investment in counter-UAS technologies accelerates. Volantyx Aerospace remains in the development stage, with its core capabilities currently undergoing hardware integration and field evaluation following initial tests in a controlled environment.

The company clarified in its release that it does not yet claim a fielded deployment, operational performance metrics, or a contract award. Volantyx Aerospace plans to begin manufacturing or supplying effectors in early 2027. The corporate name change is a structural adjustment for the Delaware corporation and does not alter existing agreements, obligations, or ownership.

AirPro News analysis

The transition from Neura Defense Systems to Volantyx Aerospace signals a strategic pivot to capture dual-use commercial and defense markets. As autonomous UAS capabilities proliferate, the reliance on RF jamming and detection is becoming a recognized vulnerability in airspace security. By focusing on multi-modal physical signatures, we view Volantyx’s approach as a necessary evolution in counter-UAS architecture. The company’s explicit acknowledgment that it lacks fielded deployments or contract awards underscores the significant gap between conceptual architecture and operational validation. The early 2027 target for effector manufacturing will be a critical milestone to monitor as the company attempts to transition from a development-stage startup to an active aerospace supplier.

The proposed industrial agreement focuses heavily on technology transfer and domestic manufacturing. Key components include the domestic assembly of an Unmanned Aircraft System (UAS) tailored for the Latin American market, the establishment of joint research hubs, and the creation of a UAS Technical Institute. The package also outlines plans to expand Peru’s high-tech maintenance, repair, and overhaul (MRO) footprint.

“As we collaborate with the local industry, we aim to deliver tangible, high-value opportunities that build a skilled workforce, enable knowledge transfer and create lasting economic impact on both sides of the partnership,” said Tara Lause, Vice President of Business Development for the Integrated Fighter Group at Lockheed Martin.

Lause added that the procurement creates enduring alliances and industrial collaboration opportunities with the United States and other partner nations.

Fleet modernization and electronic warfare capabilities

Peru is currently working to replace its aging fleet of Soviet-era MiG-29s and French Mirage 2000s. The F-16 Block 70 was selected over competing bids from Saab and Dassault. To equip the new fleet, the government of Peru selected L3Harris Technologies to provide its AN/ALQ-254(V)1 Viper Shield all-digital electronic warfare suite, a decision announced on August 17, 2026. The Viper Shield system provides advanced radar warning and jamming capabilities.

Lockheed Martin noted that the F-16 is currently operated by 29 countries, with a global fleet of 2,800 aircraft. Mike Shoemaker, Vice President of the Integrated Fighter Group at Lockheed Martin, stated that the selection highlights the aircraft’s operational performance and ability to meet pressing defense requirements.

AirPro News analysis

The announcement of a $1.8 billion industrial offset package is a strategic move by Lockheed Martin to solidify the F-16 Block 70 sale amid a complex political environment in Lima. While the Peruvian government selected the aircraft in April 2026, regional defense reporting indicates that the procurement process has encountered delays linked to ministerial resignations and defense budget debates. By offering substantial domestic manufacturing opportunities, including UAS assembly and MRO expansion, Lockheed Martin is providing Peruvian leadership with a strong economic justification to finalize the state-to-state contract. We view this comprehensive technology transfer as a critical lever in moving the procurement from selection to a finalized, funded agreement.
