Ottoman galleons make the Aegean a contested sea

The imperial arsenal at Constantinople needed years to produce or acquire enough sailing ships, including vessels of English and Dutch origin. Seasoned timber, trained builders, and a sufficiently large programme meant that the 1648 decision did not produce an operational force overnight. By 1654 the Ottomans could send a fleet with a substantial sailing-ship component against a much smaller Venetian force. Even without destroying the Venetian fleet, this adaptation changed the campaign from one-sided naval pressure into a struggle for contested sea control. The new capability remained operationally fragile, however, as Janissaries aboard the fleet complained and intrigued before its September return to the Dardanelles.
