According to a tweet of the President of the Turkish Presidency of Defence Industries (SSB), Aselsan has modernized the towed 35mm Oerlikon air defence gun system which is in service with the Turkish armed forces.
Katmanlı hava savunma sistemimizi güçlendiriyoruz.
35 mm Hava Savunma Sistemi Modernizasyonu ve Parçacıklı Mühimmat Projemiz kapsamında @aselsan ana yükleniciliğinde ürettiğimiz Ateş İdare Cihazı ve Modernize Çekili Top sistemlerinin TSK’ya teslimatlarına devam ediyoruz. pic.twitter.com/KjAz9VSLJ8

The original GDF-003B twin autocannon was produced under license by the Turkish company MKEK.
The Oerlikon is upgraded to be more efficient against current aerial threats including air-to-ground missiles, cruise missiles, and UAVs (Unmanned Aerial Vehicles).
The gun can use, among other types of ammunition, the ATOM 35mm Airburst ammunition, which is produced by Aselsan.
The German Rheinmetall also produces an Airburst ammunition, the AHEAD 35mm, which dramatically increases the effectiveness of anti-aircraft guns of this caliber, making them capable C-RAM systems.
A relevant analysis of the ammunition in question, their mode of operation and their operational value, both in the National Guard and the Greek Armed Forces, can be found at the link below.

The modernized version of the 35mm air defence gun system can be controlled by a new Fire and Control command station which is also based on a four-wheeled trailer. The system is able to control three 35mm gun weapon systems, while Rheinmetall’s SKYGUARD system can control up to four weapon stations including short range missile systems (SHORADS). The autocannons have a fire rate of 550 rounds/minute.
Aselsan’s system includes, among others, a 3D search radar, fire control radar, electro-optical (E/O) sensors, threat evaluation and weapon allocation capability. The system will be able to detect the target, identify friend or foe (IFF) and track the target by its own sub-systems using advanced algorithms.
The upgraded gun can also be integrated into the KORKUT-FCS (Fire Control System) anti-aircraft defence system. This consists of a 35mm KORKUT FCS self-propelled anti-aircraft gun (SPAAG) also using 35mm Airburst ammunition, two towed air defence guns and one Low Altitude Air Defence Missile Launching System, i.e a HISAR-A short-range missile system.
