On the newest episode of the Defense & Aerospace Business Report podcast, sponsored by Bell, we discuss the national security implications of President Donald Trump’s new tariffs on aluminum and steel from Canada, Mexico and Europe, a weaker transatlantic alliance, the Italian Navy’s Fincantieri-built ITS Alpino anti-submarine warfare frigate that visited multiple US cities last week, Capitol Hill defense-budget deliberations, and the week in defense and aerospace markets. This week’s guests include Gordon Adams, PhD, American University professor emeritus and Stimson Center distinguished fellow, Christopher Cavas, naval analyst and commentator with Round Tower Productions, Ron Epstein, PhD, of Bank of America Merrill Lynch, former Pentagon Comptroller Bob Hale, PhD, (who now advises Booz Allen Hamilton — his thoughts are his own), Sash Tusa of Agency Partners, and former Pentagon comptroller Dov Zakheim, PhD, who is now on the board of the Atlantic Council think tank. Fincantieri and Huntington Ingalls Industries sponsored our coverage of the Navy League’s 2018 Sea-Air-Space conference and trade show.
