George Wallace, USN Ret., a bestselling author and former commander of the USS Houston (SSN-713), discusses the challenges of capturing the US Navy submariner experience in print, balancing operational and national security concerns with accuracy, why US Navy submariners’ stories matter and more during a Nov. 1, 2017, interview at the Naval Submarine League’s annual symposium and industry update in northern Virginia. “Firing Point,” a novel Wallace co-authored with Don Keith, was adapted into the upcoming film “Hunter-Killer,” starring Gerard Butler.
