Commodore Hussain headed the naval base at Portsmouth
Commodore Amjad Hussain, who lives in Hertfordshire, will head the defence logistics organisation in Bath.
His last posting was at Portsmouth where he was the naval base commander.
He is an outspoken supporter of ethnic minorities joining the armed forces and said at a recent awards ceremony: "It is a wonderful life."
The engineering and business administration graduate from Durham University has served in fishing protection vessels and as a weapons officer on an aircraft carrier.
He said: "If you are working in a part of the world where your life is in danger, you need a great team. We value equality for that very reason.
"In many countries, the armed forces are often the last bastion of traditional thinking. If my example gives encouragement to young British Asians to sign up then I will be a happy man."
Commodore Hussain has also had two spells working in Whitehall in equipment and resource planning.
