He also played a role spearheading the recovery of Boeing's 787 program, and was known there as "Mr. Fix-it" from as early as 2008.

Shanahan served Boeing Commercial Airplanes as vice president and general manager of the Boeing 757 program, with responsibility for the design, production, and profitability of the 757 family of planes. He also held leadership positions on the Boeing 767 program and in the fabrication division.

Shanahan then served as vice president and general manager for Boeing Rotorcraft Systems in Philadelphia. He was responsible for all U.S. Army Aviation programs and site activities in Philadelphia and Mesa, Arizona. Programs at these facilities included the V-22 Osprey, CH-47 Chinook, and the AH-64D Apache.

Shanahan served as vice president and general manager of Boeing Missile Defense Systems, starting in December 2004 overseeing the Ground-based Midcourse Defense system, Airborne Laser and Advanced Tactical Laser programs.

United States Department of Defense (2017–2019)

Deputy Secretary of Defense

On March 16, 2017, President Trump announced his intent to nominate Shanahan as the 33rd Deputy Secretary of Defense, the Pentagon's second-highest civilian position. Trump nominated Shanahan to lead plans to increase the size of the military.

Shanahan's Senate confirmation hearing took place on June 20, 2017. During the hearing, Senator John McCain, a proponent of providing arms to Ukraine, threatened to block Shanahan's nomination over his response in a written statement about whether or not the U.S. should provide such weapons to Ukraine. Shanahan said he did not have access to classified military information in order to make a decision on the matter.

Robert O. Work, the Deputy Secretary of Defense at the end of the Obama administration, remained in the position until Shanahan's confirmation. Shanahan was confirmed by the United States Senate with a vote of 92–7 on July 18, 2017, and became the 33rd Deputy Secretary of Defense on July 19, 2017.
