Commander Marcus Paetsch, of the NATO group's flagship FGS Donau, said that all the information gathered will be passed on to the Maltese authorities and to the Malta Aviation Museum.
Two of the aircraft located, a British-made Hawker Sea Fury fighter plane and an American A-1 Skyraider bomber, were already located in 1998, when 3 Italian mine hunters conducted a survey which was later called off due to bad weather.
They were found to have remained in a good condition, Aviation Museum director Ray Polidano said.
The 1998 survey also registered a number of hits which could not be identified due to weather conditions. With no such troubles on Wednesday’s search, these hits could now be identified, and 2 further aircraft, a Bristol Beaufighter and a Fairey Firefly, were discovered.
Mr Polidano said that a Beaufighter was recorded lost in the area while on a practice bombing run, after it was struck by its own bomb splash.
He added that no records of a Firefly being lost in the area exist, which suggested that the aircraft was a target drone, a remote-controlled aircraft used for target practice. Such Fireflies were painted in a bright yellow-red scheme to clearly indicate that it was pilot-less.
Although the wrecks were found in relatively deep seas, Mr Polidano said that it would be possible to recover them. However, there is no intention to do so – unless it is determined that they are at risk.
Mr Polidano said that a running concern was the damage which might be done by trawling, adding that trawlers have, in all probability, already led to the loss of other examples of aviation history.
