During the Gulf War, OLFI was primarily stationed in the Southern Persian Gulf (SAG) where no actual fighting took place. The crew that served aboard the "OLFI" during its first combat sortie all received Forsvarets medalje (the Danish defence medal), and Kuwait Liberation Medal (Saudi Arabia).
Four days after departure from Denmark, the Iraq War began, and OLFI received new orders; to proceed to the Gulf area at best speed and join the coalition forces. The ship made a short stop in Spain and the Greek island of Crete in order to replenish before proceeding through the Suez Canal.
After joining the coalition at the base in Bahrain, OLFI operated at the front line in the North Persian Gulf (NAG) and far up the Iraqi rivers; especially the waterways of Kwah Ab Allah (KAA). The vessel never got involved in actual combat. All missions were carried out successfully without a single shot being fired. Among the coalition forces it was quite remarkable that OLFI could carry out all of its missions during the war only by peaceful and diplomatic means.
Also present in the Persian Gulf area was the Danish submarine . This vessel primarily operated in the Southern Persian Gulf in order to protect the Strait of Hormuz.
Upon their return to Denmark, the entire crew except the commanding officer of the Olfert Fischer received the Forsvarets medalje. The commanding officer did not receive this medal because he received it after serving as the operations officer (OPO) of the Olfert Fischer during the first Gulf War.
