The design work of the Close Air Defence System was completed and the technology demonstration prototype was produced. A land version of the system for the protection of troops and facilities is also being developed.

The project is expected to be completed in the second half of 2022 to equip ships against missiles, bullets, UAVs, and helicopters. The system includes a 20x102 mm 6-barrel rotary gun with a high firing rate developed by Mechanical and Chemical Industry Corporation (MKE) and an ammunition supply unit with a capacity of 1500 pieces. 

Each barrel has a rate of fire between 3000 and 4000 rounds per minute. The turret has a traverse of 360° and elevation from -15° to +85°.

The Close Air Defence System will provide at least 5 kilometers day/night vision capability and laser range measurement.

The Turkish Naval Forces use the Phalanx Close-in weapon system and Sea Zenith Close-in weapon system in ships currently, but these systems cannot be upgraded.
