The Swedish modernization of their coastal troops is continuing, with the formal call for tenders for a new surface-to-surface anti-ship missile. The new weapon will receive the formal designation RBS 18, and unlike the current man-portable Hellfire-missile system used in the short-range anti-ship role by the Swedish marines will be mounted aboard the CB 90 combat boat.
“Sweden plans to acquire anti-aircraft guns for its fast-assault boats to counter drones and helicopters…”
Defense Industry Europe reports,
“FMV (Försvarets materielverk), the Swedish Defence Materiel Administration, announced the signing of a contract for the delivery of mortar-armed boats as part of the Amfbat 2030 programme.”
The Mortar equipped assault craft appears to be a resurrection of the previously cancelled Combat Boat 2010 program. The associated Patria 120mmAdvanced Mortar System could also be used in a direct fire mode.

The Amphibious Battalion operates between sea and land with the overall task of preventing enemy amphibious assaults. With the new maritime artillery, the fire controller on, for example, a Combat Boat 90 HSM can provide target data to the firing platform, enabling the firing of grenades at a high rate of fire while advancing, for indirect engagement of various types of ground targets.

What we are seeing is a comprehensive overhaul of Sweden’s approach to littoral combat for their Amphibious Battalions (Amfibiebataljonen) of the Swedish Armed Forces from Stockholm and Gothenburg, assigned with defending the coastline, including numerous islands, against potential amphibious assaults.
While the mortars will be mounted on new construction boats, the new air defense and anti-ship missile systems will be mounted on existing CB90 (combat boat) assault craft.
The CB90 is a very popular product, used by at least nine different nations including the US, UK, and Ukraine. The Russian Navy even has what appears to be unlicensed copies of the craft. Mexico’s eight ship Oaxaca class Offshore Patrol Vessels carry a CB-90 HMN Patrol Interceptor in their well deck.
The CB90 displaces 23 tons and is 52 feet long with a 12.5 foot beam.
If a weapon system fits on a CB90 it will certainly fit on any of the US Coast Guard’s patrol boats and larger cutters.
In all probability the AAW weapon system will include a 30mm chain gun. Short range AAW missiles are possible. Perhaps the APKWS.
The anti-ship missile may be something entirely new. The closest to the description I know of, other than the MARTE MK2/N mentioned in the article, is the Spike NLOS.
