No. 4 Squadron RNZAF was a New Zealand patrol bomber unit in the South Pacific during World War II.

History

Due to activity by German surface raiders, the squadron was hurriedly formed in October 1940, initially equipped with a range of hurriedly converted civilian airliners, the twin engined de Havilland DH.89 Dragon Rapide, and four engined de Havilland DH86 Express from Union Airways of New Zealand and de Havilland DH.60 Moth single engined machines from aero clubs - New Zealand's modern Vickers Wellington bombers having been offered to the RAF for the war in Europe, two years previously.

Squadron Leader G R White was the first commanding officer and stayed with the squadron for two years. The squadron moved to Fiji that month to assist 5 Squadron, and it took over obsolescent Vickers Vincent biplane torpedo bombers and later re-equipped with modern Lockheed Hudsons. When war with Japan broke out No. 4 Squadron remained in Fiji operating as a reconnaissance unit, and also for training crews to reinforce units in the forward area.

In May 1943 three American ships, the William Williams, Hearst and Vanderbilt, were torpedoed by Japanese submarines. Hudsons of No. 4 Squadron found the survivors of the Hurst and dropped supplies, as well as maintaining an anti-submarine patrol over the crippled William Williams was she was towed 120 miles north to Suva.

On 25 May a squadron machine sighted a surfaced submarine while escorting an American convoy and dropped four depth-charges. An oil slick appeared - after the war it emerged a Japanese submarine was lost at this time in the area.

On 7 September a squadron Hudson damaged a second submarine while escorting the American ship Saugatuck. 5 other sightings and attacks were made by the squadron without result.

The squadron re-equipped with Lockheed Venturas in 1944. In November it shifted base to Emirau, remaining there until February 1945, Guadalcanal from May 1945 to June 1945 and Emirau again in June and July of that year before moving to Los Negros where it remained when the war ended, disbanding in September 1945.
