AN/ASQ-239 F-35 electronic warfare / countermeasure system

F-35 electronic protection

F-35 fighter aircraft
The AN/ASQ-239 system is an advanced, proven, and cost-effective electronic warfare suite, providing the F-35 with end-to-end capabilities, now and into the future.

Electronic warfare heritage

BAE Systems has been at the forefront of innovation for more than 60 years, providing advanced aviation solutions for aircraft around the world. Building this long-standing heritage, it has produced more than 10,000 tactical systems, emerging as the industry leader in electronic warfare.

BAE Systems’ technology is currently flying on more than a dozen platforms and remains unsurpassed in the field all across the electromagnetic spectrum. The foundation for that success was born in the 1950s, when it developed advanced radar defense and surveillance technology. The revolutionary breakthroughs embodied therein drove the creation of a state-of-the-art countermeasure system that was aboard all U.S. carrier-based aircraft during the Vietnam War.

Over the course of the next 20 years, BAE Systems developed industry-leading countermeasure technology that led to an integrated electronic warfare suite and low observable antenna system for the F-22. On this firm foundation, BAE Systems has continued to build upon its capabilities with the development and delivery of the AN/ASQ-239 electronic warfare suite for the F-35 Lightning II.

Next generation technology

The AN/ASQ-239 system protects the F-35 with advanced technology for next generation missions to counter current and emerging threats. Equipped with offensive and defensive electronic warfare options for the pilot and aircraft, the suite provides fully integrated radar warning, targeting support, and self-protection, to detect and defeat surface and airborne threats.

The system provides the pilot with maximum situational awareness, helping to identify, monitor, analyze, and respond to potential threats. Advanced avionics and sensors provide a real-time, 360-degree view of the battlespace, helping to maximize detection ranges and provide the pilot with options to evade, engage, counter or jam threats.

Always active, AN/ASQ-239 provides all-aspect, broadband protection, allowing the F-35 to reach well-defended targets and suppress enemy radars. The system stands alone in its ability to operate in signal-dense environments, providing the aircraft with radio-frequency and infrared countermeasures, and rapid response capabilities. AN/ASQ-239 is a platform-level solution that provides the F-35 with improved reliability and maintainability, helping reduce long term life cycle costs to keep the aircraft fielded now and into the future.

In 2018, BAE Systems reached a critical program milestone with the successful insertion of new technology into its electronic warfare systems for the global fleet of F-35 Lightning II fighter aircraft. The Digital Channelized Receiver/Techniques Generator and Tuner Insertion Program (DTIP) technology, upgrades the AN/ASQ-239 system and positions it to meet future capability requirements, improving the warfighters ability to conduct critical missions in contested airspace. The improved electronic warfare system delivers the world-class functionality of the previous system in a smaller footprint, reducing volume and power requirements creating space for future electronic warfare modernization upgrades.
