Mr. Altwegg was SEA-06B when I worked for him as a Division Director. He clearly defined the ascension of leadership over mere management, and our relationship will always be a sincerely respectful one for me.

Mr. Altwegg was the GREATEST! We will truly miss him at MDA. He helped so many of us in our careers not to mention is superior commitment to this country. For that and more we are truly thankful! My heart is truly sad for the family, but know that you will continue to be in my prayers.

Mr. Altwegg was one of the best "bosses" that I have ever had. He was truly a wonderful man, and a great leader.

A few of my favorite memories was when he hired me to work for him at NAVSEA as his EA, I sit in a chair in his office which sank almost to the carpet and it felt like I was getting smaller and he was getting taller (he was always tall in my eyes)...trying to get him to use all his fingers when typing, I don't think I ever succeeded...and my greatest memory was when he took time out of his busy schedule to go see my son who was a Plebe at U. S. Naval Academy providing him support and mentorship. My son is 31 now and still remembers that visit and Mr. Altwegg's words of wisdom.

You always knew where you stood with Mr. “A”. My admiration and devotion for him is beyond what words can express.

I will miss him so much, what a great loss to our country, DoD and the United States Navy.

My heart goes out to his family to whom he loved dearly.

Mr Altwegg was an inspriation for those that worked with him on BDM. I had that priveledge beginning back at the start up of SM-3 then known as SM-X. He words of "Don't be TE or Hardware poor during the development phase" are words to live by. He will be missed.

Admiral Altwegg was truly a great man. I found his strength, leadership, intelligence, and endless energy very inspiring. He also had a great sense of humor which made him seem very approachable despite his high profile position.

His passing is a huge loss not just for his family and friends, but our great nation.
