Navantia Australia has presented the new Alfa 4000 Light Frigate design during the Indo Pacific 2025 Maritime Exposition in Sydney.
=====================
The Alfa 4000 is a significant redevelopment of earlier proposals the company offered for Australian and other international requirements. These two designs were the Tasman-class corvette and the Alpha 5000 Combatant. The shipbuilder two years ago at Indo Pacific 2023 proposed the Tasman-class for the then notional "Tier 2"-requirement of the Royal Australian Navy. The Tasman-class is directly related to the Alpha 3000-design the builder has sold as "Avante"-class to Saudi-Arabia.
Navantia terms the warship a "light frigate", based on the somewhat moderate armament, which is identical with that of the earlier Tasman-class. Missile-capacity includes 16 cells of the Mk 41 VLS in Strike-length, and four quadruple launchers for NSM antiship missiles. Guns include the Bofors 57 mm autocannon on the bow and a smaller CIWS above the hangar, resembling the Rheinmetall 35 mm Millenium gun. The frigate also carries two triple launchers for lightweight torpedos and decoy launchers. A helicopter landing pad and hangar can accommodate a medium weight helicopter such as the MH-60 Seahawk.
While Navantia, as outlined, has considerable history in presenting new variants of export designs tailored to anticipated requirements, the Alfa 4000 has recently made one step closer to possible production. As Swedish media reported on November 4, the Swedish government has downselected Navantia's Alfa 4000 frigate together with competing designs from French Naval Group and British builder Babcock, possibly in cooperation with Swedish Kockums. In discussion with Naval News officials from Navantia Australia particularly emphasised the builder's ability to rapidly deliver the new warships. Sweden has a requirement for four new frigates.
