Crates containing 18 Sea Gladiators Mark I (serial numbers N5518 – N5535) from 802 Naval Air Squadron, were left at Malta in early 1940 by . Three of the airframes (N5532, N5533 and N5534) were later shipped to Britain to take part in the Norwegian campaign and another three were sent to Egypt. In March, although Malta was not facing attack, it was decided that six Gladiators would be assembled to form an air defence unit. The Hal Far Fighter Flight was to include both FAA and Royal Air Force personnel. Five aeroplanes were eventually assembled, including N5525, N5527, N5530 and N5533 but a few days later, they were dismantled again.
