AN/MPQ-64 Sentinel in the 2014 Russia-Ukraine War

The AN/MPQ-64 Sentinel appears in Ukraine's air-defense network through U.S. transfer and training records, NASAMS-related procurement, sustainment reporting, and a visually documented Ukrainian radar loss.

  3. CRS places Sentinel in Ukraine's NASAMS context

    A Congressional Research Service brief described AN/MPQ-64 Sentinel as a primary NASAMS component and stated that Ukraine had already received a number of Sentinel radars.

Documented Use

Direct proof of use

The United States publicly committed two AN/MPQ-64 Sentinel air-surveillance radars to Ukraine on April 13, 2022 as part of an $800 million security-assistance drawdown for the 2014 Russia-Ukraine War. In the same day's Pentagon briefing, John Kirby described the Sentinel as an air-defense radar system and said Ukrainian forces would need some training on it.

The strongest public record identifies the Sentinel as a transferred, trained, sustained, and package-listed air-defense sensor rather than as a weapon independently credited with a named interception. Oryx later listed one Ukrainian AN-MPQ-64 Sentinel radar as destroyed, based on photo or video evidence, placing the system in Ukraine's visually documented wartime equipment record.

Timeline

The documented sequence begins with the April 2022 U.S. drawdown and training discussion, continues through public NASAMS reporting in late 2022, and is reinforced by a later DSCA sale notice that named an AN/MPQ-64F1 Sentinel radar in a Ukraine NASAMS package.

A 2025 Operation Atlantic Resolve oversight report adds sustainment context: maintenance of Patriot, NASAMS, and AN/MPQ-64 Sentinel radar systems was to be conducted at a contractor facility in Jasionka, Poland, with DoD personnel conducting radar-system maintenance at the regional technical assistance center.

Role in Ukrainian air defense

Sentinel's Ukraine role is sensor and targeting support for air defense. U.S. and CRS sources connect the radar to Ukrainian air-defense assistance, while NASAMS documentation treats the MPQ-64F1 Sentinel as part of the radar layer that supplies target data to the wider system.

The available public sources support transfer, training, package inclusion, maintenance, and loss evidence. They do not publicly identify a specific Ukrainian firing engagement, interceptor launch, or shootdown that can be attributed to one named Sentinel radar.

Its baseline mission is to detect, classify, track, and locate mortar, artillery, and rocket launches in 90-degree or 360-degree modes, while software and open-architecture upgrades have extended the same family into counter-UAS, air-surveillance, and wider multimission radar roles.

It tracks assigned targets, coordinates with S-300V launch vehicles and command elements, and provides the radar channel needed to guide missiles against aircraft, cruise missiles, drones, and selected ballistic threats. Ukrainian reporting in January 2026 documented a Russian 9S32M1 being struck in Donetsk region during the Russia-Ukraine War.
