Operational control of the squadron came under Fleet Air Wing 5.
• 15 August 1943: Six crews were sent to San Diego, California, to pick up half of the squadron’s allotment of aircraft. After their arrival the crews completed their familiarization training using auxiliary fields at Naval Auxiliary Air Station Chincoteague, Virginia, and Marine Corps Air Station Cherry Point, North Carolina.

• 2 March 1944: Over a period of four months, sections of three aircraft at a time were transferred back to St. Eval, England, under the operational control of FAW-7. By 13 July 1944, the entire squadron was gathered at St. Eval in preparation for its return to Naval Air Station Quonset Point, Rhode Island.

The squadron came under the operational control of FAW-14. A brief period of training for South Pacific operations was undertaken through the end of September.
• 24 September 1944: VB-111 personnel (13 officers and 102 enlisted) boarded USS Makassar Strait for transportation to Naval Air Station Kaneohe Bay, Hawaii. Aircrews began the trans-Pacific flight on 1 October 1944, with the last section arriving on 5 October 1944.

On the 29th, the squadron received orders to transfer to the combat zone at NAB West Field, Tinian. The last section of aircraft arrived on 1 December 1944, and the squadron came under the operational control of FAW-1. Strategic long-range searches were conducted from that location through the middle of January 1945.
• 5 January 1945: Two squadron PB4Y-1s, flown by Lieutenant Howard E. Sires and Franklin B. Emerson, spotted an attacked a midget submarine 2 miles (3.2 km) southwest of Chichijima. The submarine was sunk using 250-pound G.P. bombs and strafing with 50-caliber guns.
• 15 January 1945: The squadron and its headquarters were relocated to Naval Amphibious Base Morotai under the operational control of FAW-17, with a detachment of four aircraft at Tacloban Air Base, Leyte, Philippines, under FAW- 10. Long-range reconnaissance missions and anti-shipping patrols were carried out from both locations.
• 1 February 1945: VPB-111 began transferring personnel and assets to the Tacloban Air Base from Morotai. By 6 February 1945, the entire squadron had been relocated, with a detachment of four crews at McGuire Field, Mindoro. Long-range reconnaissance missions and anti-shipping patrols were carried out from both locations.
• 17 March 1945: The Mindoro detachment rejoined the squadron at Tacloban to prepare for the upcoming invasion of Okinawa. Interdiction cover patrols for Task Force 58 en route to Okinawa began on 21 March 1945.
• 11 April 1945: VPB-111 relocated to Palawan Army Air Field. On 1 May 1945, the squadron received several new PB4Y-2 Privateers as replacements for its worn-out PB4Y-1s. With its new and refurbished complement of aircraft, the squadron commenced a series of daytime strikes on targets along the Borneo and Malaya coasts. On one such mission against the enemy installations at Singapore, two squadron Privateers were teamed up for an attack. One of the aircraft was badly damaged during its bombing run, and the second, flown by Lieutenant (junior grade) Romayn F. Heyler, flew through heavy enemy fire to protect its withdrawal from the area. During the escape from the target area a squadron of enemy fighters attacked the Privateers. Lieutenant (junior grade) Heyler’s crew managed to shoot down one fighter and damage several others while escorting their squadron mates safely back to base. For his heroic actions while protecting his comrades Lieutenant (junior grade) Heyler was later awarded the Navy Cross.

During the test flights all of the aircraft were operational, with no down time for repair.
