The 417th Bombardment Squadron was a United States Army Air Forces unit. It was activated in the fall of 1939 as the 27th Reconnaissance Squadron and moved to Puerto Rico two months later. Following the attack on Pearl Harbor it engaged in antisubmarine patrols in the Caribbean until the antisubmarine mission was taken over by the Navy. In the spring of 1944, it returned to the United States, where it was disbanded on 20 June 1944.
History
The squadron was first organized in September 1939 the 27th Reconnaissance Squadron (Long Range) at Langley Field, Virginia, and assigned to the new Puerto Rican Department, which had been organized in July. Drawing its personnel from various organizations stationed at Langley, the squadron's ground echelon embarked on the bound for Puerto Rico on 17 November 1939, arriving at Borinquen Field, Puerto Rico on 21 November. The air echelon, with nine Douglas B-18A Bolo bombers, arrived on 5 December.
Borinquen was a newly opened field and, in addition to flying training flights, squadron members engaged in making their quarters more livable. As the military garrison at Borrinquen grew, the squadron provided the cadre for the 5th Reconnaissance Squadron, which was activated on 1 April 1941 and continued training the 5th until it began independent operations in September.
After the Pearl Harbor Attack, Flight A of the squadron deployed to Camaguey Airfield, Cuba in April 1942, from which it patrolled the Old Bahama Channel until August 1943, except for a brief period in May 1942.

On 22 April 1942, the squadron was redesignated as the 417th Bombardment Squadron. while the Navy assumed the antisubmarine patrols the squadron had been performing.
In April 1944 the squadron returned to the United States and was disbanded on 20 June, with most of its personnel used to form cadres for heavy bomber units being formed by Second Air Force.
