The successful first flight tested the new advanced capabilities aboard the U-2 as part of the ATR contract, including:
• An updated avionics suite (communications, navigation, display, etc.) that modernizes the U-2's onboard systems to readily accept and use new technology.
• A new mission computer designed to the U.S. Air Force's open mission systems (OMS) standard that enables the U-2 to integrate with systems across air, space, sea, land and cyber domains at disparate security levels.
• New modern cockpit displays to make pilot tasks easier while enhancing the presentation of the data the aircraft collects to enable faster, better-informed decisions.
During this mission, the aircraft successfully performed a low-altitude functional check flight to integrate new avionics, cabling and software.

"The successful first flight of the U-2 Avionics Tech Refresh is a significant moment in our journey to rapidly and affordably field new capabilities," said Sean Thatcher, U-2 Avionics Tech Refresh program manager at Lockheed Martin Skunk Works. "Leveraging the platform's open architecture, we're expediting these capabilities needed for the future Joint All-Domain Operations battlespace."

The ATR first flight marks a milestone in the U-2's modernization efforts and its path to being the first fully OMS-compliant fleet. Further testing will solidify a mature software baseline before mission systems are introduced to ensure both functionality and interoperability to meet operational needs. The U-2 ATR contract was awarded by the U.S. Air Force in 2020 and valued at $50 million.
