Upon the outbreak of World War II, Gilormini offered his services to the Royal Air Force and served with them. As a member of the RAF, he flew in a squadron of P-39s from England to North Africa and participated in the Allied invasion of Oran.

He served with the RAF until November 30, 1942, when he joined the United States Army Air Corps with the rank of second lieutenant. In October 1942, he was assigned to the 346th Fighter Squadron and flew the P-39 interceptor.

On May 19, 1943, Gilormini was involved in an aircraft accident when his P-39 went down over Maison Blanche, Algiers. In an interview, Colonel Earl Miller, a former buddy and roommate of Gilormini, recalled the following:

"Gilormini was the commander of "A" Flight while I was commander of "C" Flight. We sometimes flew together. In fact, our last combat mission was attacking the airfield at Milano. I led the attack. The flak was real heavy. The 88 shells were bursting all around and also hitting a high bank (we were flying real low) to my right. Mike said, "Dutch, you better bail out, you are on fire!" Followed immediately with, "Don't bail out, it's another guy." Unfortunately, my wingman crashed and was killed."

In 1945, Gilormini was awarded the Silver Star Medal, G.O. (General Order) #27, for "Conspicuous Gallantry in Action" for his actions during the Conneto, Italy mission, while assigned to HQ, 12th Air Force Gilormini and Miller flew their last flight in Italy together giving air cover for General George C. Marshall's visit to their group at Pisa. They both returned to the United States on the same ship. Gilormini was also the recipient of five Distinguished Flying Crosses.

The Distinguished Flying Cross is a medal awarded to any officer or enlisted member of the United States armed forces who distinguishes himself or herself in combat in support of operations by "heroism" or extraordinary achievement while participating in an aerial flight. Also, in 1945, Puerto Rican poet Francisco Rojas Tollinchi paid  homage to Gilormini in his poem "Recuerdo yaucano" (Remembrance of a Yaucano).
