It's interesting that there are two organisations competing for Turkey's naval point defence system, though I think Roketsan will secure the contract because of their more advanced seeker solution and made for purpose system. Compared to Aselsan's adaptation of Goksur AA missile and single seeker - VLS is a nice addition however.

The Gökdemir 100 system can operate with 8 missiles ready to fire at a range of 20 km and an altitude of 10 km using existing RF-guided Gökdoğan AA missiles. Thanks to its own command control, it can work in integration with existing radar systems and the Siper air defense system.
ASELSAN CEO Ahmet Akyol stated that the work for the GÜRZ hybrid air defence system’s serial production began in 2024 in his 2024 summary of developments.

Turkey has placed an initial order of 5 systems for evaluation purposes, this number is likely to increase ten fold once accepted into service.

The GÜRZ 150 is a fully autonomous air and missile defense system designed to counter a broad spectrum of airborne threats at very low and low altitudes. Equipped with a proprietary fire control algorithm, it ensures optimal weapon allocation for various targets.
Key Features of the GÜRZ 150
The system is capable of engaging a wide range of targets, including:

Serial production test firing of HISAR-O completed successfully, this is the IIR seeker variant of the missile, the aerodynamic cap jettisons during terminal phase.
Did someone from Tübitak gave a reason why they are using liquid fuel for the Gökhan ramjet and not solid one (like most of the competition, besides perhaps India).
Is it just for the speed control advantage?
My best guess is, they have the intention to follow US/S.Korea/Japan in the Hypersonic cruise missile business (Hydrogen fuel+Scramjet like X-51A) and use this missile as a stepping stone to get familiar with the challenges.

"The Tayfun family will not be just one product, just one missile. Tayfun will actually be a family of ballistic missiles where there are multiple blocks, with different ranges and different warhead
Production continues as it is, and the development of new variants is also proceeding at full speed to increase the diversity of this family. Turkey will become one of the leading countries in the world in terms of ballistic missile technologies in the upcoming period."
"ASELSAN #GÖKTAN firing test
-Rocket engine integrated into TOLUN to provide ground-to-ground strike capability,
-Mission planning and firing with Command Control - Fire Control software and hardware,
-Precision strike on long-range targets by opening its wings after separation from the DeltaV rocket "
Test launch of 'GÖKTAN', rocket motor assisted TOLUN SDB glide bomb
At IDEX 2025, Turkiye's leading missile manufacturer, Roketsan, showcased its indigenous vertical launch system (VLS), "MIDLAS," featuring quad-pack surface-to-air missile launching capabilities and a newly introduced ability to launch anti-ship missiles.
SOM-J is a variant of the SOM Missile System Family specially designed for F-35 Joint Strike Fighter (JSF) internal carriage, F-16, Unmanned Combat Aerial Vehicles (UCAVs), Turkish Fighter (KAAN) and is used against heavily defended high value stationary ground and moving maritime targets.
Roketsan releases footage of another test launch of Kara Atmaca Land Attack Cruise Missile, range and flight duration increased - no figures given, however we know the previous test launch was 400km.
ASELSAN's GÖZDE Guidance kit is Turkey's first Guidance kit to hit a target moving at high speed.
Developed jointly with TÜBİTAK SAGE, the GÖZDE guidance kit converts 500 lb. MK-82 general purpose bomb into ANS/KKS and Laser Seeker Head (LAB) guided munitions, enabling accurate and very cost-effective engagement of fixed and very fast moving targets without using specialized munitions.
In Turkey, there are various Guidance Kit for MK general-purpose bombs
GÖZDE is best for high-speed moving targets (e.g., vehicles, boats).
TEBER is a versatile option for both fixed and moving targets, offering good maneuverability.
HGK is optimal for stationary targets, similar to JDAM.
LGK is ideal for moving targets, but it lacks GPS.
KGK is suited for long-range attacks on fixed targets, optimal for stationary.

Some details of the test;
GOKTAN system successfully tested
ASELSAN has successfully conducted a live-fire test within the scope of GÖKTAN project, marking a significant milestone in precision strike capabilities. Previously designed for air-to-ground missions, TOLUN guided munition has now been adapted for ground-to-ground engagements for the first time. The successful test demonstrated ASELSAN’s expertise in developing advanced strike solutions for next-generation battlefield requirements.
In this groundbreaking test, TOLUN was integrated with a rocket engine, allowing it to achieve Mach 1.02 speed, ascend to 49,880 feet, and cover 17.9 km. At 54 seconds, the munition successfully separated from DELTA-V rocket, deployed its folding wings, and entered its guided flight mode before striking its target with pinpoint accuracy. This achievement highlights GÖKTAN’s capability to deliver precision strikes on high-value targets while maintaining operational flexibility.
Developed under ASELSAN’s leadership in collaboration with DELTA-V, GÖKTAN system enhances precision engagement through integrated command-and-control and fire control systems, enabling mission planning and optimized firing sequences. This test validated the adaptation of TOLUN to a ground-launched configuration, expanding its operational flexibility and demonstrating its capability for long-range strikes.
GÖKTAN is designed to provide platform-independent strike capabilities, ensuring the neutralization of critical targets without requiring platform maneuvering. It supports 360-degree firing capability, waypoint-defined targeting, independent and centralized operation modes, multi-target engagement, and sequential firing, making it highly effective in dynamic combat environments. By combining precision, flexibility, and advanced targeting features, GÖKTAN reinforces its role as a game-changer in modern warfare.
ASELSAN President & CEO Ahmet Akyol emphasized the significance of this achievement, stating: “We have reached a key milestone in equipping TOLUN with ground-launch capability. As we continue to develop force-multiplier systems, this advancement enhances Türkiye’s precision-strike capabilities and expands its operational flexibility.”
“All major subcomponents of GÖKBERK have been designed and produced domestically, reinforcing Türkiye’s defense industry autonomy,” according to the company’s statement.
