Hamina class [luokan] missile boats

The Hamina class [luokan] includes missile boats PGG Hamina (80), PGG Tornio (81), PGG Hanko (82) and PGG Pori (83). Hamina class is used for maritime transport protection and surface combat. The vessels are also well suited to complement air defence, air and surface monitoring and electronic monitoring. Hamina-class ships belong to the coastal fleet of 7. And their home port is at the Upinniemi base.

The hull of the vessel is aluminum and the overhead cover structures with carbon fiber reinforced composite structures. The vessels are light and agile in relation to their size. In addition, the conventional propellers in missile boats have been replaced with efficient water jet propulsion. The vessels are accelerating, slowing and turning in an extraordinary way and are able to operate in very shallow waters due to their lightness. The vessels are also designed in such a way as to produce the most possible acoustic, magnetic, heat generating or radar-visible triggers.

Minister of Defense Jussi Niinistö authorized the Finnish Defense Forces Logistics Department to sign contracts for the renovation of Hamina class missiles on 19 December 2017. On Thursday, January 4, 2018, the Logistics Department of the Finnish Defense Forces signed an agreement with Patria Systems Oy, which is the main supplier of the renovation. The overhaul involves purchasing a torpedo weapon from Saab Dynamics Ab.

Under the name LV2000MLU, the project aims to extend the life of Hamina-class vessels to the 2030s. The project will develop naval mobile underwater surveillance and submarine anti-submarine capabilities by acquiring a lightweight peddler system. In addition, Hamina class missiles are equipped with subsea surveillance subsystems.

The project will integrate a new anti-aircraft missile system into the Hamina class and improve the airborne and short-range defense capabilities of the class. The ship's combat systems will be upgraded and the Hamina-class operating time will be increased by a ship technical overhaul to meet the project performance requirements. The acquisition will safeguard the ability of the Navy to provide situational awareness, mobile underwater surveillance, surface and aerial combat and underwater intervention.

The Hamina class is used to protect and combat marine traffic. Vessels are also suitable for air defense supplementation, air and surface surveillance and electronic surveillance. The Hamina category includes missile boats PGG Hamina (80), PGG Tornio (81), PGG Hanko (82) and PGG Pori (83). Hamina-class ships belong to the coastal fleet and their home port is at the Upinniemi base.

In 2018 weapons underwent a major overhaul: brand new light beasts and a weapon to be selected in the context of the Anti-Surface Missile 2020 project. Body-guided machine guns are replaced by remote-controlled weapons. Current anti-aircraft missiles remained. The spaces will be repositioned in a tight ship. More versatile hardware is promising, while today's computers take up less space than before. Electronic 3D modeling software helped with the design, for example. Most of the accommodation remains intact. Now, though, all conscripts will have their own locker, and there will be sockets on the walls.

Hamina-class weaponry consists of anti-aircraft missiles, anti-aircraft missiles, cannon, ship rifles, launchers, mines and depth bombs. These weapons can be used to fight the missile with the exception of the sea missiles, mines, and depth bombs. However, the importance of a ship machine gun is almost non-existent because of its small size and high speed of the vessel.

Umkhonto is an infrared search missile manufactured by Denel, South Africa. It is a short-range anti-aircraft missile that is mainly intended as a part of the ship's own protection system. The missile was developed by SHAV-3 (Surface-to-Air High Velocity-3). SHAV-3 development began in the mid-1980s. The missile sought to replace the country's French Crotale missile and its base was the Crotale platform. This version was named SHAV-IR, a later development version known as Umkhonto. Umkhontowas first introduced in 1998,

The Swedish Saab Torpedo 47 was chosen for the torpedo. Performance on the water will be improved by the system selected for the Anti-Shield Missile 2020 project. It will replace the current Anti-Sea Missile 85 system.

The 57mm ship cannon is made by Bofors in Sweden. Bofors 57mm MK 1 came in 1966. The cannon was designed for surface and air defense purposes and was especially suited the ends of relatively small and light ships. The development of cannon led to experience of the Second World War and the need to develop a larger caliber cannon instead of the traditional 40mm. The popularity of MK 1 gave rise to the need to develop a superior cannon that could also fight anti-sea missiles, led to the development of MK 2a. The MK 2 cannon was first introduced in 1985. Special attention was paid to the design of the MK 3 cannon for next generation warships.

The close protection of Hamina missile boats has been based on previously body-guided machine guns, requiring one fighter per weapon. The new remote control system automatically monitors the target and determines firing values, and targets the target based on information from other sensors. So the weather, the amount of light and the skill of the shooter are no longer so much affected, and only one operator is needed at a time, instead of the previous one and two shooters. The sensor system is being upgraded so that ships can produce better target data independently for ever greater distance. Underwater monitoring is again enhanced by echo meters.

The purpose of ship sensors is to collect information about the world around the ship. Based on the information gathered by the sensors, the vessel is able to react around it,things to do. The TRS-3D radar is an EADS (European Aeronautical Defense and Space Company) a multi-use radar with a phased plane antenna. It is intended for different specifically to create an aerial and surface snapshot, although it can also be used take the lead. The radar provides distance, direction and elevation information from the target, and the direction and speed of the object can be calculated. Height information is obtained by phasing transmitters so that they emit one sharp pulse in a specific direction, this angle on the horizon is known. The radar operates in the G-band, that is, in the 4-6 GHz range, and emits a wavelength of 5-7.5 cm. At this wavelength, sufficient range and accuracy are achieved because the smaller the wavelength, the more accurate the measurement. It can detect targets even over 180 km. The radar rotation speed is 60 rpm, depending on which mode is selected for use.

EOMS (Electro-Optical Multifunction System) is an electronic product manufactured by Sagem. The optical multi sensor developed by combining two previous systems to each other: VIGY 105 Electro-Optical Director and VAMPIR MB Dual-Spectrum Infrared Search-and-Track (IRST). The system consists of a TV camera, lasera rangefinder, an infrared camera, and a frame with a motor, which enables the IRST function. The device can detect -20 ° to + 60 ° on the vessel objects. The device's infrared camera operates in the range of 3 to 5 and 8 to 12 µm. The laser rangefinder is eye-safe and operates in the 1.54 µm, 20 Hz range.

The procurement decision for the Hamina class missile boats was made in connection with the Fleet 2000 procurement decision. However, in that case, the intention was to acquire only two major ships, two missile boats and 4-8 smaller hovercraft. Changes in the armed forces, however, the performance requirements for 2010 caused the hovercraft to acquire only two more missile boats to replace the hovercraft. This was because the performance requirements for the 2010s were to protect communications, and for this task, missile boats were much better at hovercraft. The main functions of the Hamina class vessels are surveillance and territorial integrity security, prevention of maritime threats and attacks, and protection of maritime links. Their design was based on Rauma class missile boats. Hamina based experience with silencing emphasized the importance of stealth. With its small size and their shallow depths, they are able to move throughout the depth of the archipelago,hide in the shelter provided by the archipelago.
