The Atılay class (Turkish: Atılay sınıfı), developed under the project name MİLDEN (Turkish: Milli Denizaltı, lit. 'National Submarine'), is a class of air-independent propulsion (AIP) attack submarines currently under construction for the Turkish Navy.

The project represents Turkey's first indigenous submarine design and development program, intended to reduce reliance on foreign suppliers for critical naval platforms. The lead boat of the class, Atılay, began construction at the Gölcük Naval Shipyard in late 2025.
