Operational history

 * 1 July 1931: VP-5S was established at NAS Coco Solo, Panama Canal Zone, while on exercises at Naval Station Guantanamo Bay, Cuba, coming under Commander Air, Scouting Force with sister squadrons VPs 3S, 8S and 10S. Upon completion of Fleet Problem No. XII, newly designated VP-5S returned to its home base at NAS Coco Solo.
 * 1 February 1932: VP-5S and VP-2S were transferred for patrol duties to NAS San Diego, California.
 * March 1932: VP-5S flew to San Francisco, to take part in Fleet Problem XIII, based on USS Wright (AV-1). They returned to San Francisco for Fleet Problem XIV in February 1933.
 * 1 April 1933: VP-5S was redesignated VP-5F, under the organizational command of Base Force.
 * 22 April 1933: VP-5F was reassigned to its old home base at NAS Coco Solo, with VP-2F.
 * May 1933: VP-5F flew from NAS Coco Solo to NAS Norfolk, Virginia, then on to Philadelphia, where the squadron's PM-2 aircraft were turned in. New P2Y-1 seaplanes were received at Norfolk and were prepared for the return trip to Coco Solo. In June the second division of six squadron aircraft returned to Coco Solo with several stops in Florida and Jamaica.
 * 7 September 1933: The squadron's first division made the first nonstop flight from NAS Hampton Roads, Virginia, to NAS Coco Solo, in six new P2Y-1 seaplanes under the command of Lieutenant Commander Herman E. Halland. The squadron flew a distance of 2059 mi in 25 hours and 19 minutes, establishing the longest nonstop seaplane formation flight to date, surpassing the previous record by 169 mi. Upon arrival, the six new aircraft were turned in to VP-10F in exchange for six slightly older P2Ys.
 * 21 April 1934: VP-5F, 2F, 3F, 7F and 9F participated in Fleet Problem XV in support of fleet operations off Cuba, Haiti, the Dominican Republic and Puerto Rico.
 * 1 January 1935: VPs 5F and 3F participated in exercises in the Caribbean to test seaplane operations in the open ocean from tenders USS Wright, USS Lapwing (AM-1), USS Teal (AM-23) and USS Gannet (AM-41).
 * August 1935: VPs 5F and 2F participated in advanced base operations in Trujillo Bay, Honduras, tended by USS Lapwing and USS Teal.
 * January 1936: VP-5F conducted advanced base operations at Santelmo Bay, Perlas Islands, tended by USS Teal.
 * 23 February 1937: VP-5F participated in extended flight operations in the Caribbean with VP-2F, based at Guantanamo Bay, Cuba; Mayaguez and San Juan, Puerto Rico; St. Thomas, Culebra; and Balhia Honda, Colombia.
 * 1 October 1937: VP-5F was redesignated VP-5 when Navy patrol squadrons were reorganized under the command of Patrol Wings. VPs 5, 2 and 3 came under Patrol Wing-3, NAS Coco Solo.
 * 14 May – 14 September 1938: VP-5 departed Coco Solo for NAS Norfolk, where the squadron turned in their P2Y-2 seaplanes. On 18 May the squadron arrived at NAS San Diego, California, to receive replacement PBY-3 Catalina aircraft and transition training in the new seaplanes. By August nearly all of the crews with the new aircraft had experienced problems with high noise levels in the PBY-3 while on patrols. The sources of the problems were found to be the lack of interior insulation in the aircraft and higher propeller tip speed. Subsequent production incorporated insulation and dressed down propeller tips that greatly reduced the noise problem. The squadron returned to NAS Coco Solo on 14 September 1938.
 * 11 February 1939: PatWing-3 squadrons, including VPs 2, 3 and 5, participated in Fleet Problem No. XX as part of the Black Force during exercises in the Caribbean. VP-5 operated in the Semana area off Cuba, supported by USS Langley (AV-3). The exercises again pointed out the vulnerability of the patrol aircraft in the face of determined anti-aircraft (AA) fire from defending vessels, and the vulnerability of the patrol bases ashore to naval or air attack.
 * 14 April 1939: VPs 5, 2 and 3 mapped 1076 mi of Central American coastline from Nicaragua to the Colombian border. This task was carried out despite weather conditions unfavorable for aerial photography.
 * 11 September 1939: VP-33 was assigned to Neutrality Patrol duties in the Caribbean operating out of Guantanamo Bay, Cuba.
 * 31 January 1940: VP-33's Neutrality Patrol duties were directed at covering convoys between the Canal Zone and Guantanamo Bay, Cuba.
 * 1 July 1940: The squadron had seven aircraft operating out of NAS Coco Solo and three out of San Juan. On 1 July 1940, the squadron received orders to fly all of the squadron aircraft to NAS Jacksonville, Florida, to be turned in for newer model PBY-3 aircraft.
 * 1–8 December 1941: By this date, VP-32 was conducting routine patrols for the Army off the coasts of the Canal Zone, supported by USS Sandpiper (AVP-9), USS Matagorda (AVP-22), USS Osmond Ingram (AVD-2), USS Goldsborough (AVD-5) and USS Clemson (AVP-17). On 8 December 1941, after the Attack on Pearl Harbor, six aircraft and crews from VP-52 reinforced the squadron. The Army and Navy combined commands after this date, with the Army assuming command of the Panama Sea Frontier, and VP-32 becoming the long-range reconnaissance arm of the Sixth Bomber Command. VP-32 operated under the operational control of the Army until 30 April 1942.
 * 15 December 1941: The squadron established advance bases at Almirante, Panama; Grand Cayman Island, Fonsec, Honduras; Castilla, Honduras; and Portland Bight, Jamaica.
 * 3 January 1942: VP-32 was supplemented by six more aircraft and crews from VP-81.
 * 23 June 1942: Lieutenant (jg) May and crew attacked a German U-boat and were credited with probable damage. Although the primary tasking had shifted on 1 May 1942 to Anti-submarine warfare (ASW) and convoy patrol, few submarine sightings were made during this period by the squadron.
 * 12 July 1942: Lieutenant (jg) Pinholster and crew attacked a U-boat in the Caribbean and were credited with probable damage.
 * 25 July 1942: Lieutenant (jg) Skelly and crew spotted a suspicious vessel off the coast of Honduras and forced it to heave to by firing shots across its bow. Skelly landed his PBY, deployed a rubber raft and boarded the vessel. A quick search revealed that the vessel was supplying U-boats with supplies and torpedoes hidden in a false bottom. The vessel, Racer, was taken into port and the crew of Axis sympathizers taken into custody.
 * 3 August 1942: VP-32 deployed to Salinas, Ecuador, operating under the Sixth Bomber Command, USAAF.
 * 19 August 1942: VP-32 deployed to NAS Guantanamo Bay, Cuba, and was placed under Commander Caribbean Sea Frontier, operating under C.C.S.F. operations Order #1-42.
 * 1 October 1942: VP-32 was placed under PatWing-11 for administrative purposes. Primary duties consisted of convoy patrols and ASW.
 * 1 December 1942: VP-32 received five new PBM-3Cs. Crews began transition training at NAS Coco Solo, from the PBY-3 to the PBM aircraft. Crews from the detachment at NS San Juan, were rotated in for the transition training. The squadron continued to operate PBY-3s alongside the newer PBM.
 * 1 April 1943: VP-32 was reassigned along with the rest of the FAW-3 to FAW-11. By this date, complete transition to the PBM aircraft had been completed.
 * 15 July 1943: Squadron aircraft conducted an attack on a U-boat in the Caribbean at 15-58N, 73-44W. The claim was judged probable sinking, postwar examination of German records confirmed this was U-159.
 * 26 July 1943: A U-boat was attacked at 18-06N, 75-00W, and judged probably sunk, postwar examination of German records confirmed this was U-759.
 * 28 July 1943: A U-boat was claimed sunk (probable) at 15-57N, 68-30W by the NS San Juan detachment, postwar examination of German records confirmed this was U-359.
