Helicopter Securing and Transfer System

Developed jointly by STM and Altınay Defence, Türkiye’s first indigenous and nationalHelicopter Securing and Transfer System provides an integrated solution that enables Sikorsky Sea Hawk SH-70 TN helicopters to land safely on naval platforms such as frigates, patrol boats, and replenishment ships under challenging sea conditions, day or night.

The system incorporates a multidisciplinary engineering infrastructure, combining image processing, positioning, embedded software, control algorithms, and hydraulic and pneumatic drive mechanisms. Utilizing cameras and a laser system integrated into the helicopter, the system calculates the real-time position of the helicopter, ensuring precise positioning of the capture device and accurate approach angles for the pilot.

Upon landing, the capture device automatically engages its claws to secure the helicopter. The entire operation is designed to be managed safely by a single operator from a control station, eliminating the need for personnel on the landing area during operations.

Türkiye’s first indigenous and national Helicopter Securing and Transfer System was integrated into TCG İSTANBUL (F-515), Türkiye’s first national frigate for which STM is the main contractor, and became operational in 2023.
