The Meteoro-class offshore patrol vessel, also known as Buque de Acción Marítima (BAM), are new modular offshore patrol vessels of the Spanish Navy adapted to different purposes from a common base, manufactured by Navantia. The BAMs combine high performance with mission versatility, a high commonality with other ships operated by the Spanish Navy. Acquisition and lifecycle costs are reduced. Description The BAMs are a common platform for a variety of missions, used to develop whole families of types of ships that meet the diverse needs of the Navy. Its main missions are: Protection and escort of other ships in low intensity/asymmetric warfare situations Control of maritime traffic Control and neutralization of terrorism and piracy Operations against drug trafficking and human trafficking Search and rescue Support for crisis situations and humanitarian aid Control of fishing laws Control of environmental legislation and anti-pollution. Modular design enables the ships to be modified for purposes outside main missions such as hydrographic research, intelligence gathering, diving support and salvage operations. Building The BAM project consists of 12 vessels. First phase The first phase included the construction of six patrol boats. This phase was completed in January 2019 after twelve years. Second phase Like the first phase, this second is composed of six units. four of them are patrol boats and the two remaining are specialized BAMs, one oceanographic and the other underwater rescue.

Characteristics of the Underwater Rescue BAM (authorized for construction at a projected cost of 166 million Euros in 2021; construction to begin in Spring 2023 and planned for delivery in 2026) Rescue and support to the rescue of submarines. The new rescue vessel will be known as the BAM-IS (Intervención Subacuática/Underwater Intervention). Support for diving operations. Intervention and rescue in accidents and shipwrecks.
