Navantia has guaranteed it can deliver two ALFA 4000 frigates by 2030, as the Swedish Government prepares to decide on a supplier for its new Luleå-class frigates early this year.
In a press statement dated 13 April 2026, the company said it could deliver two ALFA 4000 units by 2030 and a further two by 2031, should Sweden proceed with an acquisition.

Navantia’s offer also includes full operational capability throughout the vessels’ entire life cycle.
In addition to Spain’s Navantia, Sweden’s Defence Materiel Administration (FMV) has assessed competing frigate proposals, including Babcock’s Arrowhead 120 variant and Naval Group’s FDI design.
Navantia said that its ALFA 4000 is the “reliable high-capacity choice” for the Luleå programme.
“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,” it said.
The ALFA 4000 is a 120-metre (m) frigate with a 16.2m beam and a full-load displacement of 4,300 tonnes. It reaches speeds over 27 knots and offers a range of 4,500 nautical miles at 15 knots.
The ship uses a diesel-diesel combined engine system with electric assist and is equipped to operate NH-90 or SH-60 helicopters.
For air defence, the frigate is equipped with radar and electronic support/countermeasures for threat detection and classification, a vertical launch system for surface-to-air missiles, and 57/40mm guns for close-in protection. Its surface warfare capabilities include long-range anti-ship missiles, a main 57mm gun, and remote weapon stations for self-defence.
Anti-submarine features include hull-mounted sonar, towed sonar, a torpedo system and a helicopter integrated with the combat management system, allowing digital sharing of sonar data and firing authorisations.
The ALFA 4000 forms part of Navantia’s range of smaller escort vessels, targeting navies seeking alternatives to larger frigates while balancing cost with operational needs.
The platform offers configuration options for sensors, weapons, and systems and is aimed at both fleet acquisition and modernisation needs.
