CHS – Coastal Hydrographic Ship

Navantia's Coastal Hydrographic Ship (CHS) is an innovative vessel designed for the Spanish Navy, aimed at renewing and modernizing its hydrographic fleet. The main mission of these ships is the production and maintenance of the State's official nautical charts in Spanish waters and coasts. Additionally, they support the Fleet with geographic, environmental, and meteorological information and contribute to the protection of underwater archaeological heritage. CHS vessels are equipped with advanced technology, including echo sounders, side-scan sonar, and positioning systems, allowing high-precision hydrographic and oceanographic surveys. A standout feature of the CHS is its ability to operate with biofuels, complying with the latest emissions regulations and advancing the Navy's green transition. Furthermore, these ships are equipped with autonomous means such as an ROV (Remotely Operated Vehicle), a USV (Unmanned Surface Vehicle), and a hydrographic boat, which expand their operational and data collection capabilities.

The development of CHS reflects Navantia’s commitment to innovation and sustainability, providing the Spanish Navy with modern and efficient tools for exploring and monitoring its jurisdictional waters. These ships improve the Navy's operational capacity and ensure that Spain remains at the forefront of hydrographic technology and environmental protection.
