ITDS Part 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 Part II of the Improved Risk 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 supply real-time situational consciousness and counter evolving threats. The brand new system would Frequent Missile Warning System (CMWS) presently utilized by the Military.

Improved Risk Detection System
The Improved Risk Detection System (ITDS) is the subsequent technology Missile Warning and Risk Detection System that can equip present and future U.S. Military Aviation platforms. The system will present the next decision two coloration infrared sensor suite with a menace agnostic strategy to plane survivability, says the service.
ITDS will present the aptitude to detect, classify, cue, and declare on present and rising Electro-Optical/Infra-red (EO/IR) threats. The system may even present applicable Hostile Hearth Indications (HFI), differentiating between small arms and rocket threats.
ITDS can be interdependent with different methods, 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 essential functionality is required for Military Aviation to keep up overmatch towards close to peer threats and permits superior ways by means of 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 Part I Achievements and Part II Aims
ITDS Part I targeted on know-how demonstration and maturation to guage vendor options and technical maturity, concluding in Could 2025 with over 51 hours of flight testing. The service chosen final yr Northrop Grumman and Lockheed Martin to supply options for Part I.
Military evaluators replicated ways utilized in present fight operations, assessing the sensors’ capability to detect, classify, and cue a variety of threats, from small arms hearth to anti-tank guided missiles and MANPADS. The checks evaluated the sensors’ effectiveness in operationally life like situations.
Part II emphasizes supply of ITDS prototypes, together with design refinement, demonstration testing, structure analysis, prototype software internet hosting, missile warning sensor characterization, and operational integration. The efficiency can be once more rigorously evaluated throughout flight testing forward of Part 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 Growth Doc (A-CDD) accepted in July 2025 requires ten prototypes for testing and integration, and 100 fieldable methods.
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 essential 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 hearth, rockets, anti-tank guided missiles, small arms, and larger-caliber weapons.
Dennis Neel, Northrop Grumman’s Survivability Growth Packages Director, mentioned “ATHENA can see the place pilots can’t, even trying by means of an plane flooring,” providing situational consciousness beforehand restricted to bigger platforms. ATHENA offers the power, equally to the F-35’s Distributed Aperture System, to view any level in 360 levels across the plane and even “look by means of” 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 path. The elevated detection vary, decision, and processing energy give pilots and countermeasure methods extra time to reply to threats, bettering survivability and mission success.
Integration with Current Techniques
ATHENA is designed to combine with present countermeasure methods, 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 knowledge enhance response occasions and effectiveness of present protections. ATHENA’s modular, scalable structure helps legacy and future plane, networked battlefield knowledge hyperlinks, and integration with different survivability applied sciences.
Actually, as required by the Military, the system needs to be Modular Open Techniques 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 methods, such because the Frequent Missile Warning System (CMWS) and Restricted Interim Missile Warning System (LIMWS), supplied essential safety however have been restricted in protection, detection velocity, and adaptableness. 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 subtle air protection networks, unmanned aerial methods, 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.
