Serving the Mission’s of Tomorrow | MX12B Mode 5 IFF Level 2B Transponder

The invasion of Ukraine by Russia has brought global security concerns to the forefront, especially regarding the military capabilities of authoritarian states. This presents a significant challenge for the United States and its allies, requiring updated strategies, strengthened collaborations, and innovative technologies to effectively address current and future conflicts. The MX12B Transponder, a Mode 5 Level 2B Identification Friend or Foe (IFF) solution, holds immense potential in minimizing fratricide, enhancing situational awareness, and expanding airspace capabilities. In this article, we will explore the expected impacts of this advanced transponder technology.

Increased Situational Awareness: In modern combat environments, distinguishing between friends and foes is crucial to determining the outcome of conflicts. The MX12B Transponder with ADS-B In and Out capabilities enables crewed aircraft to effectively identify and track drones, ensuring tactically deconflicted operations. By equipping drones with Mode 5 Level 2B-Out and crewed aircraft with Mode 5 Level 2B-In, defense services can utilize their assets more efficiently, enabling improved situational awareness and airborne deconfliction. This enhanced awareness translates into better decision-making and operational effectiveness on the battlefield.

Improved Interoperability: The MX12B Transponder’s integration of ADS-B In and Out capabilities facilitates improved interoperability between military and civilian aircraft. This feature proves particularly beneficial during joint operations involving federal, state, local, and civilian agencies, such as law enforcement, search and rescue, and wildfire management. Additionally, with future conflicts potentially overlapping with civilian airspace, proper identification and classification of all airborne traffic become critical to prevent civilian collateral damage. The MX12B Transponder ensures seamless integration into the National Airspace System, enabling effective coordination and collaboration among different entities.

Manned & Unmanned Teaming: In over-the-horizon and contested airspace operations, robust avionics and autonomy packages are essential for successful missions. The MX12B Transponder’s Mode 5 IFF Level 2B In and Out capabilities play a crucial role in enabling encrypted surveillance and autonomous deconfliction. Equipped with ACAS X-based DAA (Detect and Avoid) systems, unmanned aircraft can automatically avoid collisions with other aircraft while responding to Mode 5 Interrogations. This enables manned and unmanned teaming, allowing traditional fighter aircraft to effectively coordinate with unmanned counterparts.

Compliance with Civilian Airspace Requirements: As many countries transition to ADS-B as the primary means of air traffic control within the National Airspace System, military aircraft are required to be equipped with ADS-B Out to comply with civil airspace requirements during training missions. The MX12B Transponder’s inclusion of civilian ADS-B ensures seamless compliance without the need for hardware configuration changes. This not only streamlines operations but also enhances safety by integrating military aircraft safely and fully into civilian airspace systems.
