Dornier Do-22KG is a drawing of WhyMe, but belongs here, so I include it with its history in Hellenic Air Force service. I am thankful to WhyMe for this drawing, adding only some small detail for this particular airframe.
Royal Hellenic Air Force had 12 Do-22 seaplanes, order of 1938 and were received into 1939 ,serving with the 12ΜΝΣ (Naval Co-op Sq.). During the Greek-Italian war,six (other sources say nine) where taken by the 2MΣΣ (Army Co-op Sq.), converted to land planes and were painted Light Earth/Dark Green/Light Blue they were first used in naval convoy escort, anti-submarine patrol, and naval reconnaissance missions, including searching for enemy minefields. Later, nine were fitted with conventional landing gear instead of sea-landing floating system, because Hellenes were desperately short of army cooperation aircraft (conversion was carried out in December 1940 - January 1941 in SHAF). They were also expected to be used for night bombing missions against the Italian forces at Tepeleni, but only one such mission was carried out. From the sum of 12 aircraft,ten survived the Greek-Italian war, but until April of '41, only four were still in service. Around that period, one Do-22 seaplane managed to escape to Aboukir, Egypt, along with other remnants of the RHAF. The three remaining aircraft were destroyed by the Germans.
The sole Hellenic Do-22KG aircraft to cross the Mediterranean was the numbered "N-27", that reached Abukir, but was forced to ditch while flying to Alexandria by a faulty oil circuit leak.
