How was the submarine's name spelled when she was a Turkish submarine?
While in Turkish service, Razorback was named TCG Muratreis (S-336).
She was named after a 16th century Ottoman vice admiral known as Murat Reis, or Admiral Murat.
Although the person's name is two words, the submarine's name was only one word, as clearly shown by artifacts in our collection:
This patch was donated to AIMM by Captain Joseph Talbert, Razorback's last American Commanding Officer. He received it from the Turkish Commanding Officer, Captain Metin Caha, during the turnover process.
This is a Turkish enlisted uniform cap. Several of these caps were found aboard the submarine during the conservation process, having been left behind by the last crew.
This is a close-up of the band from the above uniform cap (the difference in color is due to a change in the lighting).
This is a shoulder tab from a Turkish enlisted uniform. It was actually found underneath a piece of machinery, so there is no telling how long it had been on the submarine.
From all of these artifacts it is clear that the Turkish name for the submarine was one word, not two.
