Navantia’s ALFA 4000 is the reliable high-capacity choice – now and for the long term. It brings together what matters: a Sweden-tailored configuration, enduring through-life support with Swedish industry, and delivery on schedule.
While awaiting the Swedish government’s decision on the Luleå programme to acquire four frigates, Navantia highlight the ALFA 4000 frigate as the lowestrisk option and the one best aligned with the Swedish Navy’s requirements.
As an advantage over other competitors, Navantia pointed to the guarantee of delivering two stateoftheart ALFA 4000 units in 2030 and the other two in 2031, as well as full operational capability throughout the entire life cycle.
This implies considerable flexibility on Navantia’s part and a commitment to longterm local industrial cooperation. In this regard Navantia already has experience of cooperating with SAAB on the integration of Swedish systems.
Navantia also highlighted its competitive advantage, supported by the Spanish government and the Spanish Navy (Armada), to ensure the training of the crews.

AIR DEFENCE, SURFACE WARFARE, ANTI SUBMARINE WARFARE
· Air defence (AAW). Radar and electronic support measures/countermeasures (ESM/ECM) provide air picture and threat classification; a flexible VLS enables surface- to-air missiles from local to area air defence. The 57/40 mm guns provide close-in protection.
· Surface warfare (ASuW). Long-range anti-ship missile (RBS-15), 57 mm main gun for sea/land targets and remote weapon stations for close-in self-defence (Saab Trackfire 30 mm).
· Anti-submarine warfare (ASW). Quiet platform with hull-mounted sonar and active/passive towed sonar, torpedo system, and NH-90/SH-60 helicopter system. The helicopter is fully integrated into the ASW system via the CMS – sonar data, tracks, and firing authorization are shared digitally, keeping the sensor-to-effect chain coherent.
With the ALFA 4000, Navantia is expanding its portfolio of smaller-tonnage escort vessels as an alternative to large frigates, in a segment where several countries are seeking to balance cost, availability, and capabilities. The company positions the design as a customer-configurable platform (sensors, armament, and systems), with the aim of competing in fleet acquisition and modernization programs.
