The squadron was formed at RAF Gibraltar on 20 September 1943 from 1403 Flight.

[5][6] Equipped with Lockheed Hudsons, it was tasked with collecting meteorological data from both the Mediterranean and Atlantic.

In February 1944 it was re-equipped with Handley Page Halifaxes and these were supplemented by Supermarine Spitfires, although the Spitfires were replaced with Hawker Hurricanes a few months later.

In September 1944 the squadron absorbed 1500 (BAT) Flight and its Miles Martinets, which were used for target towing.

The squadron continued to serve for a while after the war was over, and was even given an air-sea rescue task,[2] using the Warwicks, but was disbanded at Gibraltar on 25 April 1946.
