Shanahan will run the Pentagon interim until Trump agrees to a permanent replacement.

But who is the new Minister of Defense? Here are five things you should know about Shanahan:

1. He has no military experience

Shanahan, 56, did not serve the military and has little experience in foreign affairs and government. This makes him an unusual choice for Secretary of Defense. Shanahan serves as Deputy Minister of Defense, where he oversees the daily supervision of the agency and budget.

In an interview with Defense News, Shanahan said he believed his role was "to operationalize national defense strategy, drive systematic change and reorganize the organization to increase our performance in terms of lethality, alliances and reforms . "

We often focus on processes, budget or effort, "he said. "The Pentagon should focus on results and results – our performance. This focus on performance should lead us to unleash unsurpassed lethality, implement our modernization plans, and achieve this affordably. "

. 2 Prior to his appointment as Deputy Minister of Defense, Shanahan spent more than three decades with Boeing. Throughout his career, he has held various executive positions within the Vice President Aerospace Company; The Puget Sound Business Journal once called him Boeing's "Fix-It" man. He oversaw the work on new aircraft and missile and laser protection systems.

According to his Department of Defense Bio, Shanahan holds two advanced degrees from MIT: a Master of Science in Mechanical Engineering and an MBA from MIT's Sloan School of Management.

. 3 His father taught him about "service before the self".

Shanahan's father Mike was a Vietnam veteran who served in the US Army. At an October 2017 event celebrating the release of the documentary "The Vietnam War," Shanahan said, "As I grew up, my understanding of the war came from my dad, his friends, and the few stories they would tell. "

In addition, The Hill reported that Shanahan had frequently visited Trump and Vice President Mike Pence as project leaders in the Pentagon for the planned military service of the Space Force.

. 5 Senator John McCain was not a fan

Although Trump and Pence appear to be in the Shanahan fan club, the late Senator John McCain – long one of Washington's most respected voices in terms of anything to do with the military – was not.
