The Ada class is a class of anti-submarine corvettes developed primarily for the Turkish Navy during the first stage of the MILGEM project. 

The design objective of the Ada class was to build a modern littoral combat ship, with national anti-submarine warfare and high-seas patrol capabilities, while extensively using the principles of low observable technology in its design.

The Ada class corvettes have a displacement of 2,400 long tons (2,440 t), is 99.50 m (326.4 ft) in length, 14.4 m (47 ft) in beam, and has a draft of 3.89 m (12.8 ft).

The class vessels are propelled by a RENK CODAG Cross-Connect propulsion plant. It consists of a gas turbine rated at 23,000 kilowatts (31,000 hp) and two diesel engines rated at 4,320 kW (5,790 hp).

Each diesel engine drives one controllable pitch propeller via a two-speed main reduction gear. The cross-connect gear splits the power from the gas turbine via both main reduction gears to the two shafts.

The ship can be operated in Diesel mode, in single gas turbine mode, or in CODAG mode. CODAG is where diesel and gas turbine engines are providing combined power (27,320 kW).
