Stridsbåt 90 H(alv) (Strb 90 H; CB90) is a class of fast military assault craft used by several countries after being originally developed for the Swedish Navy by Dockstavarvet.

The water jets are partially ducted, which, along with underwater control surfaces similar to a submarine's diving planes, gives the CB90 its manoeuvrability.

Apart from the addition of armour, it sports air-conditioning for deployment in tropical conditions, a fuel cooling system, a 230 V generator and more powerful engines.

This boat was involved in a high-speed chase with three Greenpeace RIBs who were trying to enter the restricted area near the hotel where the meeting was being held.

[5] In 2010, Dockstavarvet Shipyard modified two CB90s to be carried in the davits of Dutch and UK Navy landing platform docks (LPDs).

[9] In 2004, the Royal Norwegian Navy conducted tests (including a live fire exercise) to evaluate the effectiveness of the SB90N as an aiming and launching platform for the Hellfire missile.

One SB90N was equipped with a stabilized Hellfire launcher based on the Protector, and its machine gun was replaced with a gimbal-mounted sensor package containing visible-light and infrared cameras and a laser designator.

Although the tests were successful, there is currently no indication that the Royal Norwegian Navy will deploy SB90Ns armed with Hellfire missiles in regular service.

On October 5, 2014, a Royal Malaysian Navy CB90 bearing registration number CB204 was reported lost at sea due to storms and high tides.

The boat was found on October 6 near Station Lima, after its distress call was heard by KD Paus, a Jerung-class gunboat, with no injuries to all 7 crew.
