VP-27 was established at NAS Norfolk, Virginia on 1 June 1944, under the operational control of FAW-5.
A few days later squadron personnel were relocated to NAAS Harvey Point, North Carolina, for training as a seaplane squadron flying the PBM-3D Mariner.
Between 4 and 22 August VP-27 was relocated to NAS Key West, Florida and subsequently, to NAAS Boca Chica, Florida, for training in Anti-submarine warfare (ASW) techniques, which was completed on 22 August.
The squadron returned to NAAS Harvey Point for crew leave, and preparation for the cross-country flight to NAS Alameda, California.
From 28 September to 1 October the squadron departed for NAS Alameda in detachments of three aircraft.
Upon arrival on 1 October, the squadron aircrews were tasked with ferrying aircraft for FAW-8 from NAS Alameda to NAS Kaneohe Bay, Hawaii.
On 25 November VPB-27 was relieved of duties with FAW-8 and boarded USS Attu for transportation to NAS Kaneohe Bay, Hawaii, arriving on 9 December.
Upon arrival the squadron came under the operational control of FAW-2.
Duties at NAS Kaneohe Bay consisted of training and ferrying aircraft to forward areas.

From 10–18 February 1945 the squadron moved forward to NAB Tanapag Harbor, Saipan.
New PBM-5 aircraft were delivered shortly before the squadron deployed.
Operations commenced at Saipan on 18 February 1945, under the operational control of FAW-1, with the squadron flying anti-shipping patrol (ASP), convoy cover, and air-sea rescue missions.
Tender support during this period was provided by USS Onslow, USS Yakutat and USS Shelikof.
From 23 March relocated to Kerama Rhetto, Ryuku Islands, to begin ASP operations in support of the assault on Okinawa.
Operations from this location were extremely difficult due to large swells.
Every takeoff was hazardous, as the long 14-hour night flights required extra fuel and bomb loads, making the takeoff weight of the aircraft well above the recommended maximums.
This campaign was completed successfully in June, with patrols shifted to the China coast through the end of August.
On 7 August two squadron aircraft piloted by Lieutenants (jg) O. L. Edwards and B. A. Gallagher were lost due to enemy action while attacking shipping at night in the waters off Formosa.
All of the 24 aircrew were listed as killed in action.
On 15 August the squadron received orders to stand down from combat operations, bringing the fighting phase of the war to an end.
During the last months of the operation, the squadron lost eight aircraft: two shot down on a night mission, one shot down by a friendly night fighter, one from battle damage, one from detonation of bombs accidentally jettisoned, one from an emergency landing, and two damaged on reefs beyond economical repair.
From 16 September 1945 to March 1946 the squadron was based at Sasebo Harbor, Kyushu, Japan.
Duties consisted of courier and mail missions throughout the extent of the occupied Japanese islands.

In March 1946 VPB-27 returned to NAS Kaneohe Bay, under the operational control of FAW-2.
On 2 Mar 1949 VP-47 was reassigned to a new home port at NAS San Diego, California, the move was completed on 26 March.
The squadron came under the operational control of FAW-14.

From 30 January – April 1950: VP-47 deployed to NAB Saipan, with a detachment at NS Yokosuka, Japan, and NS Sangley Point, Philippines, coming under the operational control of FAW-1.
The squadron participated in ASW exercises with British naval forces in March.
Other ASW exercises were conducted in Japanese waters off Sasebo in conjunction with VP-28 during April.
With the outbreak of the Korean War on 27 June, half of the squadron was still en route to the continental United States returning from deployment.
The detachments were held up at Pearl Harbor; Guam; Sangley Point; and Yokosuka.
All of the aircraft available were rerouted to Yokosuka to begin operations in the forward combat areas in Korea.
By 7 July, the squadron's detachments had rejoined and were relocated to NAF Iwakuni, Japan.
Advance bases were set up for temporary operations at Inchon and Chinhae, Kor
