Our mast systems and submarine components represent optimal reliability and innovation. We have been serving shipyards and navies all over the world for almost 60 years. Our products can be integrated into every submarine base, conventional and nuclear, and meet all common military standards.

Mast systems

The development and production of a submarine mast system is the core business of Gabler. As opposed to the mast, limited to the lowering and lifting mechanism of a sensor, the mast system comprises the hydraulic control block, the hoistable mast control and the sensor. With us, you get everything from one source. So, we optimise your supply chain and help you to save costs.


Our masts offer smooth, sound-optimised movement in all drive positions, flexible hoisting height, high resistance to environmental conditions and a concept that saves space and weight. You can rely on our submarine masts ‒ even in extreme situations. They are made under consideration of all military standards out of composites and lightweight materials and are shock and sea-wash tested. Due to the optimised incident flow profile and the optional radar-absorbing material (RAM) coating, the devices also show a reduced signature (acoustically, magnetically, hydrodynamically, and visually). No provision nor sensor integration is required – our masts are ready to use upon delivery.

Hoistable masts

The hoistable mast is the basis for every mast or mast system. Hoistable masts mainly comprise the four main modules: guide shaft, guide piece, drive and profiled mast. Due to the specific requirements of the navies worldwide, Gabler does not only offer a standardised and modular device platform but also tailor-made solutions for every submarine platform. Depending on the requirements, we create individual hoistable mast solutions.

The Gabler hoistable masts are platforms for optronic, radar, ESM, communication and SATCOM masts, as well as for periscopes. The sensors, antennas and effectors can be combined on combination masts as desired and required by the mission profiles.

Mast options

Depending on your requirements, Gabler offers configurable options for the mast system, mast or hoistable mast. Of course, all mast options comply with all military standards in regard to strength against shock and sea wash so that their proper functioning is always ensured, even in extreme situations.


Apart from mast systems, Gabler develops and produces system-relevant key components for the submarine platform. Just like our other products, these components meet the highest requirements and comply with all military standards.

Thanks to our many years of experience in the design of electro-mechanic submarine components, we can also refine existing components of our clients or create completely new components from scratch.
