Matt Zullo CTICM (ret)

Matt Zullo is a retired U.S. Navy Master Chief Petty Officer who has more than 35 years’ experience in Radio Intelligence, now more commonly known as Communications Intelligence. He holds a Master’s degree in Strategic Intelligence from the National Intelligence University, where he researched and wrote his master’s thesis on the On-the-Roof Gang. He has published numerous articles on the On-the-Roof Gang in the Naval Cryptologic Veterans Association’s Cryptolog magazine and on social media platforms. As the world's only quantifiable expert on the subject, Matt has spoken at the 2009, 2011, and 2013 Cryptologic History Symposiums, as well as at several Navy events around the world.  Matt continues his research into the On-the-Roof Gang as he looks for opportunities to spread the word about these U.S. Navy's cryptologic pioneers.

  • An eye-opening narrative filled with new information about the birth of the US Navy’s communications intelligence. Matt Zullo’s “On the-Roof Gang - Prelude to War” is a must-read for anyone interested in the Sailors and officers who performed radio intelligence during World War II, providing a priceless advantage to operational commanders.

  • BRAVO ZULU!!!! “On-the-Roof Gang - Prelude to War” should be required reading for all the Navy’s new Cryptologists. In the current world of “Cyber” warfare, it’s often prudent to stop and think about how far we have come and pay tribute to those pioneers whose dedication and perseverance in the face of numerous obstacles were instrumental in America’s successes in WWII. We should be forever grateful for the Chief Kidders of that time. Matt Zullo takes us on an enlightening adventure culminating in a deep sense of pride in being part of such an honorable community.

  • Master Chief Zullo has hit a home run on the origins of Navy COMINT/Cryptology. His ability to relate a story that has numerous vectors into a well-spun yarn is a tribute to the Navy,s Chief Petty Officers past and present. In a sentence "It's one helluva a sea story!"  This book should be required reading, in "A" school for all Sailors, Officers, and Marines in the Information Warfare (IW) career path.  BZ Master Chief!

  • On-the-Roof Gang – Prelude to War is a fascinating read!  The attention to detail and historical research that went into this was amazing.  As a former crypto-linguist, cryptologic analyst, and instructor, this book often made me feel I was “back in the saddle” again. W.E.B. Griffin look out! There’s a new kid in town….and his name is Matt Zullo! Looking forward to seeing On-the-Roof Gang on the bookshelves, and also looking forward to Volume 2.

  • A rare look behind the veil of secrecy that cloaks Naval SIGINT operations. Matt Zullo’s extensive research and mastery of the subject matter offers great insight into the origins of the On-The-Roof Gang and gives the reader a fascinating look into the lives of these great American heroes. Although the Gang has all gone on to the realm of the Supreme Commander, Matt’s masterful storytelling ensures they will never be forgotten.
