- The IDIQ contract covers post-production services for the Generation II RFI
- The RFI is used on the Army’s Apache attack helicopters
- Army Contracting Command will assign work sites and funding with each order through 2031
Lockheed Martin has secured a $117.1 million contract from the U.S. Army to support the second-generation radar frequency interferometer, or RFI, used on the service’s Apache attack helicopters. The Department of War announced the indefinite-delivery/indefinite-quantity award Tuesday.
What Does the Lockheed Martin RFI Contract Cover?
The contract covers post-production support services for the Generation II system. It combines cost-no-fee, cost-plus-fixed-fee and firm-fixed-price terms.
The Army will choose work sites and commit funds as it issues individual orders over the five-year performance period, which is expected to end Oct. 12, 2031.
Army Contracting Command at Redstone Arsenal, Alabama, is overseeing the contract. A single bid was solicited and one proposal was received.
How Does the RFI Award Fit Into Lockheed’s Army Portfolio?
Lockheed has built interferometer technology for the Apache before. In August 2023, the Army awarded the company a $60.5 million firm-fixed-price contract to produce the AN/APR-48B modernized-radar frequency interferometer and provide related services. That system locates targets for the AH-64E Apache Guardian’s fire control radar and detects radar-guided anti-aircraft threats. It also controls the helicopter’s survivability equipment. Lockheed is performing that work in Owego, New York, through Oct. 31, 2026, using fiscal 2023 Defense Production Act Purchases funds.
Its Apache sensor work also includes a potential $1.73 billion contract modification the Army awarded in June 2025 for the Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor, or M-TADS/PNVS. The electro-optical fire control system helps AH-64 pilots fly in day, night and adverse weather. More than 1,240 of the systems have been delivered since 2005. In 2022, the Army ordered $121.6 million worth of M-TADS/PNVS hardware from the company.
The same Redstone contracting office also made a potential $3 billion award to Lockheed in July for Sentinel A4 radar production. Sentinel A4 is an air and missile defense radar built to detect cruise missiles, drones, aircraft, and rocket, artillery and mortar threats.
The new Lockheed award comes as the Army works to better protect its helicopters. Its fiscal 2027 budget request includes $107 million for aircraft survivability, a 76 percent increase over fiscal 2026. That total includes $23 million for a Phase 2 radio frequency countermeasure. The service is putting the AH-64E first in line for that countermeasure, fielding it to one battalion per year.
