General Dynamics IT gets new president after predecessor's abrupt departure

General Dynamics has appointed a new president for its IT services business unit: Amy Johnson, a 27-year veteran of the company who currently is an executive in the mission systems product unit.

Johnson will take charge of GDIT on Nov. 3, the corporation said Friday. She will replace Paul Nedzbala, who has been interim president since Oct. 3, following the abrupt departure of Amy Gilliland after nearly a decade at the helm.

Nedzbala will remain as chief business officer, overseeing GDIT’s corporate development and related initiatives, a role he took on in January.

Johnson currently works as VP and general manager of the space, cyber and intelligence line of business at the GDMS unit. This 2,500-employee team develops and fields space ground command-and-control systems, satellite mission payloads, encryption and cybersecurity products, and offerings in PNT (positioning, navigation and timing).

GDIT’s focus areas include digital modernization, cloud computing, artificial intelligence, cybersecurity and software development. The business unit reported $9 billion in revenue for 2025, up from $8.7 billion for 2024 and $8.4 billion for 2023.

When she moves over to GDIT, Johnson will lead the next iteration of a strategy laid out by Gilliland that centers around tech investments and partnerships.

Gilliland left General Dynamics on Oct. 3 after 21 years with the corporation and nine as GDIT’s president.

Looking ahead

On Jan. 1, GD President Danny Deep will succeed CEO Phebe Novakovic. She will become executive chairman of the board of directors on that date.
