Combat Boat 90 (CB90) is a high-speed military boat developed by Dockstavarvet. Initially, he conceived to replace the outdated Swedish boats fleet class 200. It is an export version of the Strp 90H, the official Swedish designation H means that the boat is able to transport and deploy up to half of the landing platoon fully armed. The boat was adopted in 1991.
The boat can be used as a high-speed means of attack and coastal defense, a patrol boat, or as a special fire support weapon. It can also be used for intelligence, surveillance, and intelligence gathering operations.
The CB90 boats are currently used by naval forces from several countries, including Norway (like S90N), Greece, Mexico (like CB90 HMN), Malaysia and Brazil. (Note by Professors: The American company SAFE Boats from Washington State acquired a license from the Swedish shipyard Dockstavarvet to build these boats and produced them around 10)
The design of the boat provides him with excellent seaworthiness, high speed, efficiency and safety under various operating conditions. The body is made of aluminum, the length of the light CB90 is 14.9 meters, the displacement is 18 tons, the maximum width of the 3.85 meter. It has a typical hull configuration with reverse saddle deck and a narrow ramp in the nose capable of passing one fighter across the width at a time.
The boat accommodates a fully armed 21 soldier and up to 4.5 tons of cargo. Protected from splinters, the wheelhouse has space for two operators and an additional folding seat between them and resembles an aircraft cabin.
The folding seat is swivel. Directly under the cab there is a bulkhead in which a passage is made to the landing nasal ramp. The unique ramp provides fast deployment of forces, as well as quick evacuation of victims to the shore.
The landing compartment housing the soldiers and their equipment is located in the middle of the boat. The 25% of the aft of the hull is an open deck and can serve as a floating command post with additional communications equipment or as an artillery boat with a possible weapon position.
Several CB90 options have been built to meet special requirements. The CB90HI boat is an export version of the Strb HS 90, where the letter S means "Skyddad" (Swedish protected). (Note from Professor, In fact, the origin of the letter S is not so unequivocal. However, in addition to additional armor, the HS model has a system of protection against OMP by creating overpressure in the compartment, a conditioner for deployment in tropical conditions, a fuel cooling system, a generator on 220 Volts and more powerful engines. The boat’s level of protection complies with NATO’s STANAG4, which means that it can withstand shots with 7.62x51 armor-piercing bullets. and to 3.8 tons and thus more powerful engines.)
The CB90 HEX model is a hybrid between the CB90 H and CB90N called Stridsbåt 90N (SB90N) in the Norwegian navy. The CB90 HEX has been optimized for the Royal Navy of Malaysia, the Navy of Mexico, the Royal Swedish Landing Corps and the Greek Coast Guard.
The CB90 NL model is equipped with a battalion-level command and control system, computer and communications equipment, and a backup generator to provide power when the engines are not running. The letter L refers to 'Ledning', which means command or leadership in Swedish.
The standard armament of the boat consists of three Browning M2HB machine guns, an 12.7-mm machine gun (or an 40-mm grenade launcher) mounted on a turret in the aft part of the wheelhouse. It can be replaced with a remote-controlled, stabilized machine-gun turret. Paired 12.7-mm machine gun mounted in front of the place for the steering. In addition, the boat is equipped with one Mk 19 grenade launcher and a modified Hellfire RBS 17 SSM system. It can also carry 2.8 tons of sea mines or six depth charges. (approx. Professor, Americans as usual on their boats stuffed so many barrels that it is hardly possible to trace their number and nomenclature.)
The CB90 boat is driven by two diesel engines rated at 600 kW, which allows it to reach speeds of 45 nodes while maintaining high maneuverability in shallow water in coastal waters. The civilian version of the patrol boat can be equipped with two diesel engines rated at 550 kW, providing maximum speed up to 45 units.
The boat is equipped with two water jet propellers Kamewa FF, which are partially located in the guide nozzle. This feature of a water jet, along with underwater control surfaces, allows the boat to perform extremely sharp maneuvers even at high speed. The maximum power reserve is about 440 km at a speed of 20 knots (37 km / h). The boat is equipped for landing operations, even on an unprepared shore.
(Approx. Professors, more than 220 boats have been produced today. The price of the boat is $ 2-3 million. Recently, some boats have been re-equipped for biofuel to test the possibility of reducing the dependence of the army on oil production)
