Arlington-based federal technology contractor CACI International Inc. announced Wednesday the death of J. Philip “Jack” London, the company’s executive chairman, at age 83. He served as chairman, president and CEO of the company from 1984 to 2007 and as executive chairman since 2007. 

“All of us at CACI are deeply saddened by Dr. London’s passing,” CACI President and CEO John Mengucci said in a statement. “It was our great privilege to know and work with him, and he leaves a legacy of outstanding success and accomplishments. He was a true pioneer in the federal contracting industry, drawing from his military service to set the standard for leading with ethics and integrity.”

London spent 50 years in the technology and federal government contracting industry. Michael A. Daniels will succeed London as chairman of CACI’s board of directors. Founded in 1962, CACI specializes in enterprise and mission technology. The company has approximately 23,000 employees and is on the Fortune 1000 list.

London oversaw major company strategic initiatives and transactions, including a merger and acquisition program he began in 1992 — which has resulted in 79 company acquisitions. He also established the company’s culture, character, integrity and ethics committee in 2015 and in 2018 the company opened the Dr. J.P. (Jack) London Shared Services Center in Oklahoma City, Oklahoma, in honor of London, an Oklahoma City native.

London earned a bachelor’s degree in naval engineering from the U.S. Naval Academy and a master’s degree in operations research from the Naval Postgraduate School. He served 12 years of active duty with the U.S. Navy during the Cold War and received several awards and recognitions for his service. He earned his doctorate in business administration from The George Washington University.

“He set the bar high for business leaders across our industry, developing a successful business that continuously excelled and stayed strong through more than 50 years of changes in the federal landscape,” Mengucci said in a statement. “Jack London was one of a kind, and all of us at CACI are grateful to have been a part of his life.”
