Today, AISTER delivered to the Headquarters of the Maritime Service of the Spanish Civil Guard (SEMAR) the sixth unit of the HS60 model, one of the most advanced high-speed interceptors in the world. The vessel, named RÍO ANTAS, is the first of the third contract awarded to AISTER and follows the recent RÍO GUADALMEDINA, presented last May at the international defence exhibition FEINDEF.

The handover took place at AISTER’s facilities in Moaña, in an event attended by representatives of the Civil Guard. After final preparations, the vessel will join maritime surveillance, control and anti–drug-trafficking operations.

A pioneering interceptor on a global scale

The HS60 is a vessel developed and built by AISTER that has set a global milestone in its class. It is the first interceptor capable of exceeding 60 knots with waterjet propulsion, combining extreme speed, advanced manoeuvrability and unique dynamic performance in tactical operations.

Its most notable capabilities include:

• Over 60 knots top speed, with excellent operational reliability.

• Crash-stop manoeuvres in under two boat lengths, even at high speed.

• Tight turns and precise control, essential for pursuit operations.

• 18-metre hull, built in high-strength aluminium and optimised for maritime security missions.

• Advanced navigation, communication and safety systems, fully adapted to SEMAR standards.

These features make the HS60 a strategic asset in the fight against drug trafficking, particularly in high-risk operational areas.

A project progressing at a strong pace

With the delivery of RÍO ANTAS, AISTER has now completed six of the eight units, further consolidating its position as a leading Spanish shipbuilder in aluminium vessels for security and defence missions.

“Each new HS60 we deliver represents a step forward in the operational capability of the Civil Guard and demonstrates AISTER’s commitment to innovation and excellence in the maritime domain. RÍO ANTAS is a vessel designed to make a difference where it is needed most,”
                                                                                       emphasised AISTER’s technical team.

The remaining two units are currently under construction and will be delivered over the coming months.

At AISTER we continue to strengthen our international presence. Our next project is the construction of two MZ12 PILOT vessels, which will be delivered throughout 2026 to a client in Central America.

This project reinforces confidence in our expertise in aluminium shipbuilding and in the development of high-performance vessels designed for pilotage services, a sector where reliability and safety are essential.

MZ12 PILOT: aluminium design and high performance

The new MZ12 PILOT vessels measure around 12 metres in length and 4 metres in beam, featuring a deep-V monohull built entirely from marine-grade aluminium. Their design has been conceived to deliver outstanding manoeuvrability while maintaining excellent stability at sea. All of this makes them ideal craft for safely carrying out pilot transfer operations in both port and coastal environments.

The propulsion system consists of twin 350 HP marine diesel engines, delivering optimal performance with speeds exceeding 24 knots. This balance guarantees that the vessels can operate efficiently and reliably to meet the demanding requirements of daily pilotage service.

Comfort and safety on board

The aluminium cabin has been designed with a clear focus on the comfort and protection of those on board. It features ergonomic suspension seats for the pilot and co-pilot, along with six additional adjustable suspension seats for pilots and crew. The large glazed area provides 360-degree panoramic visibility, which is crucial during manoeuvres to approach large vessels. In addition, noise and vibration insulation, together with air conditioning on board, significantly enhance the sailing experience, ensuring a safe and comfortable working environment.

In terms of equipment, the MZ12 PILOT vessels comply with international standards, integrating communication, navigation, rescue, bilge and fire-fighting systems that further strengthen operational safety.

Another step in our international expansion

This project reaffirms our commitment to innovation and excellence in shipbuilding, offering solutions tailored to each client’s needs and to specific operating conditions.

The two MZ12 PILOT vessels to be delivered in 2026 will be dedicated to pilot transfer operations in port environments, contributing to enhanced maritime safety and traffic efficiency across the region.

At AISTER, we continue sailing into the future, building safe, efficient vessels ready to meet the most demanding conditions anywhere in the world.

Through a promotional roller, we showcased this new configuration, specifically designed to respond to the most extreme combat conditions.

The HS60 is already a benchmark for its ability to exceed 60 knots and its extraordinary maneuverability. With the Combat version, AISTER reinforces these qualities and adapts the model to the most demanding scenarios. This 18-meter-long vessel is conceived as a multi-mission platform, used both for troop transport and for other military operations. With the Combat version, we reinforce these qualities and adapt the model to the most demanding scenarios, offering a precise, firm, and advanced response.

Our participation at FEINDEF attracted strong interest from both the media and industry professionals. Outlets such as Faro de Vigo and La Provincia highlighted AISTER’s international projection and our progress in the naval defence field, while Atlántico underlined the delivery of the fifth HS60 patrol boat to the Guardia Civil, as well as our collaborative developments with Navantia. Together, these recognitions consolidated our presence at such a key event for the defence and security sector.

For us, FEINDEF 25 was an invaluable opportunity to demonstrate our technological capabilities and reaffirm our commitment to innovation. The positive reception strengthens our determination to continue evolving our range of high-performance vessels and to deliver cutting-edge naval solutions at both national and international levels.

The HS60 Combat represents that commitment: a model designed for real missions, with greater power, enhanced control and maximum reliability under extreme conditions. Another step forward in AISTER’s trajectory as a benchmark in state-of-the-art naval construction.
