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 stabilized Hellfire-launcher based on the Protector (RWS), 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 actually deploy SB90Ns armed with Hellfire missiles in regular service. The Hellfire can still be carried on the boats without launching platforms and be fired from shore with the Portable Ground Launch System.
