CB90 Class Fast Assault Craft - Versions

Versions

Several Strb 90 H have been converted by the Swedish Navy to fill various roles:

• The Strb 90 L is outfitted for battalion-level command and control, with computer and communications equipment and an auxiliary generator to provide electrical power when the engines are not running. The L stands for ledning (command or leadership).
• The Strb 90 KompL is a plain Strb 90 H in which portable computer and communications equipment has been installed, allowing it to temporarily provide company-level command and control. Electrical power is provided by a rather loud portable generator installed on deck.
• The Strb 90 HS is designed for overseas peace-keeping and rescue operations. It is modified to keep its crew comfortable in Mediterranean conditions, with air conditioning, an auxiliary generator, a head, and more comfortable crew stations. More importantly, it is armored, and its engines have been upgraded to compensate for the added weight.
• At least one Strb 90 H, pennant number 802, is equipped with a decompression chamber.
• The Swedish Police operate one unarmed Strb 90 H equipped with bunks, a pantry and a crew lounge.
• The Swedish Sea Rescue Society operates two unarmed Strb 90 Hs converted for search and rescue.
• Hellenic Coast Guard operate also since 1998 three CB90 under the CB90HCG which is a slightly different version of the Norwegian Navy Version

The Royal Norwegian Navy operates 20 CB90s under the designation SB90N; the N simply stands for Norsk utgave (Norwegian version). The S90N differs from the Strb 90 H in a few areas:

• It is armed with only one 12.7 mm machine gun, instead of three.
• The anchor winch is motorized, and the anchor is mounted at the stern, allowing a grounded S90N to tow itself afloat rather than risk damage to its impellers.
• It carries an auxiliary generator which provides electrical power to navigation and communications systems even when the engines are not running.
• The "Troops transportation room" has a higher deck height, making it possible for most people to stand without crouching.
• It has two water tight compartments in the bow, having an extra room for toilet and stores.
• It has a much more sophisticated navigation equipment based on GPS-technology delivered by Kongsberg Seatex AS.

At least one S90N has been reconfigured into a floating ambulance.

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 M151, 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.
