Military's Chief of Staff, Marshal Fevzi, opposed naval construction and slowed down all naval building programs following the fraud charges. Intensive work on the battlecruiser only began after the Greek Navy conducted a large-scale naval exercise off Turkey in September 1928 and the Turkish Government perceived a need to counter Greece's naval superiority. The Turks also ordered four destroyers and two submarines from Italian shipyards. The Greek Government proposed a 10-year "holiday" from naval building modeled on the Washington Treaty when it learned that was to be brought back into service, though it reserved the right to build two new cruisers. The Turkish Government rejected this proposal, and claimed that the ship was intended to counter the growing strength of the Soviet Navy in the Black Sea.

In response to s return to service, the Soviet Union transferred the battleship and light cruiser from the Baltic in late 1929 to ensure that the Black Sea Fleet retained parity with the Turkish Navy.
