Rick Ambrose, the executive vice president for space at Lockheed Martin [LMT], has decided to retire on March 1 next year, the company said on Oct. 7.

After joining Lockheed Martin in 2000, Ambrose served in a number of roles, including as the president of the Information Systems & Global Solutions-National business; vice president and general manager of the Surveillance and Navigation Systems line of business within the space sector; and vice president and general manager of Mission Systems and Sensors’ Tactical Systems.

Ambrose helped lead a number of space programs and initiatives at Lockheed Martin, including the company’s space-based infrared system (SBIRS) and an agreement between Lockheed Martin and Omnispace LLC this year to pursue a space-based 5G global network to aid the Pentagon’s planned Joint All Domain Command and Control (JADC2) system and to allow users to transition between satellite and terrestrial networks without the need for multiple devices on multiple networks (Defense Daily, March 23).

In a statement, Lockheed Martin CEO James Taiclet praised Ambrose’s contributions to the company over the last two decades and his “strategic leadership” of the company’s $11 billion space portfolio.

Ambrose is to serve as a strategic adviser to the company to ease his successor’s transition.
