Hi Jaeger.
This is U-A
Info from
Uboat.net:
"The boat was almost ready as the Turkish
Batiray (the second of 4 ordered from Germaniawerft, the first,
Saldiray, had been delivered in June 1939) when the war in Europe broke out and she was not handed to the Turkish but rather commissioned into the German Navy.
The remaining two boats,
Atilay and
Yildiray, were laid down in Turkish yards under German supervision. Altiray was commissioned in 1940 but with the German engineers and designers gone due to the war Yildiray was much delayed and was not commissioned until Jan, 1946. Altiray was lost with all hands to a moored mine on 14 July, 1942.
She was briefly named
Optimist by the Germans but given her UA name on 21 Sept, 1939. She was the most successful
foreign U-boat in German service by far, credited with 7 of the 9 ships sunk by those boats. Cohausz sank all those 7 ships and Eckermann sank one."
