Operational history

• 1 April – July 1942: VP-33 was established at NAS Norfolk, Virginia, under the operational control of FAW-5, as a seaplane squadron flying the PBY-5A Catalina. Squadron training was conducted at NAS Quonset Point, Rhode Island, until mid-July.
• 9 July 1942: VP-52 was withdrawn from NAS Coco Solo, Panama Canal Zone, and replaced by VP-33. During this period the squadron came under the operational control of FAW-3 and was assigned duties of patrolling convoy routes, Anti-submarine warfare (ASW) patrols and ferrying supplies to advanced bases in the Caribbean.
• 10 July 1943: VP-33 was relieved at NAS Coco Solo for return to NAS Corpus Christi, Texas and 15 days home leave with orders to report to NAS San Diego, California.
• 15 Aug 1943: After a brief two-week period of refit with new aircraft and equipment, the squadron departed NAS San Diego, for a trans-Pacific flight to NAS Kaneohe Bay, Hawaii. Upon arrival the squadron came under the operational control of FAW-2 and quickly deployed to Kanton Island. VP-33 conducted day searches toward the Gilbert Islands covering the occupation of Baker Island.
• 26 September 1943: VP-33 was relocated to Funafuti, conducting day searches toward Tarawa.
• 26 October 1943: VP-33 moved to Perth, Australia, under the operational control of FAW-10. The squadron conducted day searches and night bombing (Black Cat) missions to Koepang and Amboina.
• 15 February 1944: VP-33 was relocated to Samarai, New Guinea, under the operational control of FAW-17. The squadron was assigned night search patrols and attack missions against enemy shipping in the Bismarck Sea.
• 25 March 1944: VP-33 was relocated to Manus Island, in the Admiralty Island chain. There it conducted daylight searches toward Truk and Woleai; bombing missions against Woleai and Wakde; air-sea rescue missions around Truk, Woleai and Yap; and coverage for the invasion of Hollandia.
• 19 May 1944: After the occupation of Hollandia, the squadron moved aboard USS Heron in Humboldt Bay. With VP-52, the squadron conducted air-sea rescue for Army strikes on Wewak, Wakde, Biak, Noemfoor, Manokwari, Babo, Jefman and Sagan.

• 26 September 1944: Lieutenant James F. Merritt, Jr., led his Catalina in an attack against two enemy transports and their five armed escorts. The attack was conducted off the southwest coast of Mindanao, Philippines, in hazardous night conditions of bright moonlight and heavy concentrations of antiaircraft (AA) fire from the armed escort ships. During his mast head bombing attack his bombs failed to release. He returned, despite the heavy AA fire, and made a successful attack resulting in probable damage to one large transport and the destruction of the other transport. For his actions he was awarded the Navy Cross.
• 3 October 1944: While patrolling Toli Toli Bay, Northern Celebes, on a Black Cat mission the night of 3 October, Lieutenant (jg) William B. Sumpter led his crew in an attack against a Katori-class cruiser.

He scored eight bomb hits resulting in explosions and the burning of the cruiser and its sinking. For his actions he was awarded the Navy Cross.
