ITDS Section II brings ATHENA sensor to Military plane, offering 360° situational consciousness and enhanced survivability towards evolving threats.
Northrop Grumman has been chosen by the U.S. Military to proceed into Section II of the Improved Menace Detection System (ITDS) Different Transaction Settlement (OTA), a key initiative to modernize plane survivability for Military Aviation. This system goals to ship superior missile warning and menace detection capabilities throughout platforms together with the AH-64 Apache and MV-75 Future Lengthy-Vary Assault Plane (FLRAA).
Central to this effort is Northrop Grumman’s Superior Tactical Hostile Engagement Consciousness (ATHENA) sensor, a next-generation system designed to offer real-time situational consciousness and counter evolving threats. The brand new system would Frequent Missile Warning System (CMWS) at the moment utilized by the Military.
We’re dedicated to shaping the way forward for protection. Our Improved Menace Detection System (ITDS) has been chosen by the @USArmy as its future menace warning system to guard plane in a variety of navy operations. 🚁✨Try the Military’s announcement:… pic.twitter.com/1P0xj3Ise1

Improved Menace Detection System
The Improved Menace Detection System (ITDS) is the subsequent era Missile Warning and Menace Detection System that may equip present and future U.S. Military Aviation platforms. The system will present the next decision two colour infrared sensor suite with a menace agnostic method to plane survivability, says the service.
ITDS will present the potential to detect, classify, cue, and declare on current and rising Electro-Optical/Infra-red (EO/IR) threats. The system can even present applicable Hostile Hearth Indications (HFI), differentiating between small arms and rocket threats.
ITDS might be interdependent with different techniques, having the ability of cueing laser-based countermeasures (DIRCM) and/or deploying expendable countermeasures (chaff and flares) through Improved Countermeasure Dispensers (ICMD). The system will select the suitable countermeasure system primarily based on the menace classification.
“This vital functionality is required for Military Aviation to take care of overmatch towards close to peer threats and allows superior techniques via elevated detection vary, improved detection in litter, and menace agnostic algorithms to quickly reply to rising threats and permit the execution of full spectrum multi-domain operations,” mentioned Col. Brock Zimmerman, PM ASE.


ITDS Section I Achievements and Section II Targets
ITDS Section I centered on expertise demonstration and maturation to guage vendor options and technical maturity, concluding in Might 2025 with over 51 hours of flight testing. The service chosen final yr Northrop Grumman and Lockheed Martin to offer options for Section I.
Military evaluators replicated techniques utilized in present fight operations, assessing the sensors’ capacity to detect, classify, and cue a variety of threats, from small arms fireplace to anti-tank guided missiles and MANPADS. The exams evaluated the sensors’ effectiveness in operationally real looking situations.
Section II emphasizes supply of ITDS prototypes, together with design refinement, demonstration testing, structure analysis, prototype utility internet hosting, missile warning sensor characterization, and operational integration. The efficiency might be once more rigorously evaluated throughout flight testing forward of Section III.
Future Outlook
The ITDS program is about to transition to the Center Tier of Acquisition Speedy Prototyping pathway within the first quarter of Fiscal 12 months 2026. The Abbreviated Functionality Improvement Doc (A-CDD) permitted in July 2025 requires ten prototypes for testing and integration, and 100 fieldable techniques.
Speedy prototyping permits the Military to speed up supply of superior survivability applied sciences whereas retaining flexibility for iterative enhancements primarily based on operational suggestions. That is vital to permit the service to counter rising threats in multi-domain operations.


ATHENA
The Superior Tactical Hostile Engagement Consciousness (ATHENA) is a staring, always-on sensor offering steady 360-degree protection. It delivers high-resolution, wide-band menace detection and might quickly geolocate incoming Electro-Optical/Infrared (EO/IR) threats, together with hostile fireplace, rockets, anti-tank guided missiles, small arms, and larger-caliber weapons.
Dennis Neel, Northrop Grumman’s Survivability Improvement Applications Director, mentioned “ATHENA can see the place pilots can’t, even wanting via an plane flooring,” providing situational consciousness beforehand restricted to bigger platforms. ATHENA supplies the power, equally to the F-35’s Distributed Aperture System, to view any level in 360 levels across the plane and even “look via” the plane flooring.
Actually, a number of sensor feeds are seamlessly stitched to create a full spherical view, permitting crews to watch threats from any course. The elevated detection vary, decision, and processing energy give pilots and countermeasure techniques extra time to answer threats, bettering survivability and mission success.
Integration with Present Methods
ATHENA is designed to combine with current countermeasure techniques, together with Northrop Grumman’s Frequent Infrared Countermeasure (CIRCM) suite, enabling automated or semi-automated responses. The corporate has beforehand outlined ATHENA because the “eyes of CIRCM.”


Fast, exact menace location and trajectory information enhance response instances and effectiveness of current protections. ATHENA’s modular, scalable structure helps legacy and future plane, networked battlefield information hyperlinks, and integration with different survivability applied sciences.
Actually, as required by the Military, the system needs to be Modular Open Methods Method (MOSA)-compliant and in a position to function on a digital spine, permitting fast integration and upgrades. This adaptability is essential as Military Aviation operates in more and more complicated and contested environments.
Strategic Context
Legacy missile warning techniques, such because the Frequent Missile Warning System (CMWS) and Restricted Interim Missile Warning System (LIMWS), offered vital safety however had been restricted in protection, detection pace, and flexibility. ATHENA addresses these gaps with broader protection, threat-agnostic algorithms, and better processing functionality, serving to Military Aviation keep overmatch towards near-peer threats and adapt to rising challenges in multi-domain operations.
Military plane face more and more refined air protection networks, unmanned aerial techniques, and superior guided munitions. ATHENA can present steady, real-time menace monitoring, permitting aviators to focus on the mission whereas sustaining the situational consciousness wanted to function successfully.
