context_page_description: Stridsbåt 90 H is a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet. In addition to the many variants in service with the Swedish Navy under the "Stridsbåt 90H" designation, the CB 90 has been adopted by the navies of several countries, including Norway, Greece, Mexico, the United States and Malaysia. Additionally, the German Navy plans to equip the Berlin-class replenishment ships with the CB90.
  The CB90 is an exceptionally fast and agile boat that can execute extremely sharp turns at high speed, decelerate from top speed to a full stop in 2.5 boat lengths, and adjust both its pitch and roll angle while under way. Its light weight, shallow draught, and twin water jets allow it to operate at speeds of up to 40 knots in shallow coastal waters. The water jets are partially ducted, which, along with underwater control surfaces similar to a submarine's diving planes, gives the CB90 its manoeuvrability.
context_section_description: 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
