The position of Secretary-General at the Ministry of Defence was abolished and replaced by the position of Undersecretary of the Ministry of Defence, and on January 16, 2014, the position of Secretary-General in the Ministry of Defence was restored again. However, on March 9, 2020, the position of the Minister responsible for Defence Affairs was abolished to be replaced by the position of Deputy Prime Minister for Defence Affairs, which is currently occupied by His Highness Sayyid Shihab bin Tariq bin Taimur Al Said.
