Finnish Navy received second modernized Hamina-class missile boat

The Finnish naval forces received the second Hamina-class missile boat to be repaired and modernized. Two more boats of this type must undergo modernization by the end of 2021. It is reported by Naval News.


In the course of modernization, the emphasis is on the fight against enemy submarines, so the boats receive funds to combat submarines and new opportunities for defense. In particular, the Torpedsystem 47 (Tp 47) torpedo launchers developed by the Swedish Saab Dynamics and the ST2400 variable depth sonar from the Norwegian Kongsberg are being installed. Also, the boat is armed with a 40-mm shipborne artillery installation "Bofors-40" Mk.4. from BAE Systems.

Four Hamina-class missile boats form the core of the Finnish Navy. They are stationed at the naval base in Upinniemi, 15 kilometers southwest of Helsinki. The first modernized boat returned to the fleet at the beginning of this year.

The hull is made of aluminum, and the superstructure is made of reinforced composite carbon fiber. The shape of the vessel was designed specifically to reduce radar visibility. Metal parts are covered with absorbent material.

The boats are armed with four container launchers of MTO-85M anti-ship missiles with a firing range of 150 km. Also, initially, the boat's armament includes a 57-mm gun mount of the Bofors company, a vertical launch installation for eight Umkonto short-range anti-aircraft missiles by the South African Denel company, as well as two 12,7-mm machine guns. The solution of anti-sabotage tasks is provided by the Elma nine-barreled grenade launcher.

The radio-electronic equipment includes a TRS-3D / I6-ES three-coordinate detection and tracking system for airborne and surface targets (maximum detection range of air targets 90 km), as well as a Zeros 200 firing system with radar, television, thermal imaging stations and a laser rangefinder. The boat is also equipped with a podkilnaya and lowered hydroacoustic stations.

Processing data from the specified radio equipment or external sources, and issuing target designation systems weapons implemented using the automated control system ANCS-2000.

      The boat turns out - "don't touch me!"
      And he can work on the submarine, and on aviation, and the enemy ship "bite".

        On pl, he can only work on paper. On the nuclear submarine, even on paper, it cannot - the displacement does not allow. Air defense is not even suitable for self-defense. Artillery weapons - absent. The anti-ship missiles of the last century, an analogue of our "Termit", whose engine was replaced. What did the people find in this boat?

          The anti-ship missile system of 2020, the air defense system is 15-20 km away for a boat more than, and its anti-aircraft missile defense system is specialized for the Baltic Sea.

            The turbojet engine, I agree, is new ... But the rest is "Termite".
            Air defense in 15-20 km for a boat more than

            The planning "Drill" works for 30 km.

              Nothing in common. Gabrielle 1 had a semi-active seeker. The new engine was already on Gabriel 4.
              Gabriel 5 has a dedicated active seeker for work in coastal waters and with high levels of interference
              The new Gabriel 5 is design to be superior compared to most contemporary missiles, particularly when employed in littoral waters. It uses an advanced active radar seeker backed by a sophisticated weapon control to optimize operational effectiveness in a target congested battlespace. The missile significantly improves target selectivity capability, especially in littoral waters, typically congested with marine traffic, and interference generating extensive and complex false target signals. As an advanced attack missile Gabriel 5 can penetrate the target's protection, both soft- and hard-kill defenses. It is designed with sophisticated electronic counter-countermeasures (ECCM) dealing with chaff, advanced decoys and active ECM.

              The planning "Drill" works for 30 km.

              "Drill" - a gliding bomb designed to destroy tanks, ground radar and air defense systems ..... The bomb is aimed at the target using the GLONASS system. The planning range of the bomb reaches 30 km

              Funny.

                Gabriel 5 has a dedicated active seeker for work in coastal waters and with high levels of interference

                With the ability to suppress interference. So in the text. In the same place, in the language of an advertising booklet, it is written about an active RGSN. What is the difference from Termit?

                  All the difference from Termit.
                  What are the similarities? Both are subsonic anti-ship missiles.
                  Well, like the Su-25 and the plane of the Wright brothers according to your logic, for example.
                  Both fly and both are subsonic.

                    What is the ceiling and range of the Su 25? I think these are two big differences. The Israelis are understandably in awe of Termit. So they are trying to catch yesterday ... Compare the aerodynamic schemes of the two PCRs ... Are they similar, right?

                      according to your logic, no difference.
                      They put a new engine, two engines, that's all, and there is no difference. smile
                      especially since
                      The Wright brothers' greatest fundamental achievement was their discovery of the three axes of rotation of the aircraft, which allowed pilots to effectively control the aircraft and maintain its balance during flight. [5] This method became the main one, and it remains so for all types of aircraft.

                      Do you see how simple your logic is? Nothing new.
                      The Israelis are understandably in awe of Termit.

                      why? In the Yom Kippur War, none of the P-15s released hit a target of fifty. And Gabrieli 1 just hit.

                        according to your logic, no difference.

                        Physics is the third grade. Topic "Bernoulli's Equation and Zhukovsky's Theorem"
                        Let's look at the photo x - 35

                        See the swept wing? Why is this done? To fly over the crests of waves, a high sweep is needed, since the rocket is in a zone of high turbulence. Note how the wings are displaced relative to the center of mass of the PCR Why is this done? The fact is that if the focus of the rocket (the point of application of the incremental lift that occurs when the angle of attack changes) is located behind the center of gravity, as in the X - 35, then with a random change in the angle of attack, and at low altitudes above the sea surface this is a common phenomenon , the increment of lift tends to tilt the rocket so as to reduce the angle of attack. As a result, the rocket returns to the previous flight mode. Conclusion layout X-35 is optimal for flight at low altitudes in turbulence zones.
                        Now let's look at "Gabriel - 5"


                        In the first photo we see that the anti-ship missile wings are located in the center of mass of the rocket. Thus, a shoulder stabilizing flight is not formed and when the angle of attack changes, there is a risk of stalling into a spin. In the second photo we see a deltoid wing with a large area and small sweep. Such a wing is chosen for flight at altitudes of 100 m - 1 km with a transonic cruising speed without performing intensive maneuvers.
                        Conclusion - Gaboiel 5 - "Termite is overgrown".

                        And the guys are Israeli and did not know until now!
                        Back in the late 80s, Gabriel 3 was adopted ...
                        When Gabriel Mk3 is launched, it rises to an altitude of 100 to 200 m, then descends to a cruising altitude controlled by a radio altimeter of 20 m.In the future, the missile's flight to the target is controlled using an INS and an onboard computer. In the search zone, the target is locked, after which the flight altitude, depending on the sea state, is reduced to one of three preset values: 4 - 2,5 - 1,5 m.

                        decreases to one of three preset values: 4 - 2,5 - 1,5 m

                        Do you yourself believe that a rocket with a trapezoidal wing of low sweep at 800 km / h at 1,5 m can make a stable flight? Vibration loads will not destroy it? Will you fall into a tailspin?
                        Forgive me, but I trust Voenmech more than advertising brochures.
                        This is how the phenomenon of the wave crisis is described in the work of Komisarchuk and Akimov "AERODYNAMIC PHENOMENA AT NEAR-SOUND AIRCRAFT SPEEDS"
                        Wave crisis - a change in the nature of the air flow around an aircraft when the flight speed approaches the speed of sound, accompanied, as a rule, by a deterioration in the aerodynamic characteristics of the aircraft - an increase in drag, a decrease in lift, the appearance of vibrations



                        Do you see what happens to the aircraft at flight speeds close to 1M and angles of attack of 6-8 degrees? Wing drag increases and lift decreases. This is due to the oscillatory nature of the shock wave motion along the longitudinal axis of the aircraft. This, in turn, creates vibration in the wing. A wave crisis occurs at a certain critical flight speed and depends on the sweep of the wing

                        If Israeli boys knew about aerodynamics as well as marketing!

                        I think that Israeli boys understand aerodynamics as well, no one thinks they are fools. Moreover, it is quite possible that, judging by the time of creation of Gabriel 5, it could well be even the Soviet boys too.

                        Gabriel rockets are bought in many countries of the world, so there is no talk of an advertising invention, they would have been brought to light long ago.

                        To conduct research on aerodynamics in the format of a website is a complete profanation. Moreover, without knowing the flight control algorithm, you never know how the computer corrects the flight, correcting the nuances of aerodynamics, and what control laws are incorporated into the autopilot.
                        I brought you the official Finnish website.
                        They have been bought for a long time, and not yesterday on the occasion, and by various countries.
                        Do you think there are no smart people on the planet besides you? And you can easily determine which rocket from the picture under an unsuccessful angle, knowing nothing about its filling and control algorithms, how it flies?

                I looked at the work.
                It looked like students wrote. Coursework or student essay level.
                1. No links to sources.
                2. The bibliographic list, to which there are no references, is mainly textbooks up to the beginning of the 60s and even the XNUMXs, like Physics of Landau and Lifshitz, and a popular science article.
                3. Statement of the problem in the article - no. Conclusions, no.
                4. The article does not consider the X-shaped wing, namely such in this rocket, but it has significant features.
                5. There is no evidence to support the stated statements.
                6. The complete relationship of the speed, shape, profile and angle of attack of the wing with wave phenomena is not shown. moreover, it is indicated that Mkr depends, for example, on the wing profile (Fig. 5. There, by the way, there are extra points, I would lower the mark for the carelessness of the design. By the way, Fig. 5.1 is taken from Wikipedia, from the article on the Sound Barrier))
                7 The article itself does not contain anything new that was not known. Has nothing to do with the topic of discussion. It is even ridiculous to argue that RCC developers do not know aerodynamics at the level of students with such sources of information as in the article.
                Conclusion. You copy and paste without understanding what. Do not waste your and other people's time.
                Success.

                so where are the girls and their marketing degrees?
                and the link says
                Gabriel Mk5 will use an advanced, active GOS, supported by a modern control system designed to optimize the overall combat effectiveness of the anti-ship missiles. The rocket will have a significantly increased ability to distinguish and select targets, especially in coastal waters, as a rule, overloaded with sea transport, as well as in the context of creating extensive and complex signals of false targets. Like most advanced anti-ship missiles, Gabriel Mk5 will be able to overcome the enemy's missile defense system, whether it is a means of functional decommissioning, or means of fire destruction. It is being developed taking into account modern actions to disrupt the operation of the enemy EW facilities, the use of advanced baits and active jamming.

Among other things, photos and videos of a missile were published for the first time, apparently the anti-ship missile "Gabriel-5"

    For nuclear submarines, he really will not work, because they are not found in the Baltic. On air defense it looks no worse than our RTOs. With rockets, your claims are incomprehensible: this rocket flies 2 times farther than Termite and much smarter. So now almost all anti-ship missiles have a flight speed like Termit, but this does not mean that they are equal to him in terms of combat qualities.

            They have an automatic Bofors with projectiles with programmable detonation.
            Bofors 40 Mk4 is a naval AU designed to provide combat surface ships / boats with a lightning reaction to a probable threat. Small weight, compact size, long range and high rate of fire - the distinctive features of the AU “Bofors 40 Mk4”. AU can quickly be switched to the use of another type of ammunition, can use programmable ZR. May use ammunition from CV90. It has high tactical and operational characteristics, high survivability. They will give priority to surface ships armed with Bofors 40 Mk4 in any military conflicts. Bringing AU into a firing position - less than one second. Programmable ammunition make it possible to use AU against any targets. Ammunition supply is automatic; AU control is remote, without human intervention or from the operator-gunner.
            Application areas:
            - various peacekeeping missions. AU can play a preventive role - warning fire;
            - various missions in law enforcement. Response / warning of threats from pirates, smugglers and terrorists;
            - combat missions in military conflicts. Ensuring the protection of the ship from ships, airplanes, helicopters, anti-ship missiles and enemy coastal objects;
            - performance of the main tasks. Patrol and protection of coastal ships.

                Sorry for the delay. It can track the target's course before entering the cloud and increase the chance of hitting by filtering out those points where the ship cannot be. She can attack repeatedly from a different angle. In the end, it can receive external target designation. For example.

        This is so that it will not be with her (Gabrielle 5), as Termite was fooled in 1973!
        Well, in general, why are you stuck with the old Termite. Right now, the RCC has completely different capabilities. The Finns held a tender (knowing the Finns, the tender was real and competent) and Gabriel 5 was chosen for a reason, among many Western competitors.

    The Chukhonts turned out to be smart people, both from the USSR and from Europe, they took it then and now they take it and do not live badly.

    And most importantly, they do not at all complex that they do not have an aircraft carrier. Why is there an aircraft carrier, they don't even have a cruiser in the fleet.

      They did not have cruisers, but there were coastal defense battleships, moreover, they built themselves. Of course, they could not cruise in the open ocean, but in the Baltic, and especially in the narrowness and shallow waters of the skerries, such an battleship was, perhaps, stronger than any light cruiser and flatter heavy cruisers, and comparable to the best heavy ones. He carried 4 guns of 254mm caliber (or, if you prefer, 10 inches) and 8x105mm, not counting any anti-aircraft trivia.

    Nice boat in 270 tons of full displacement.
    PLO, specialized and tested for coastal waters, 4 new Israeli anti-ship missiles Gabriel 5, Swedish torpedoes, new Bofors, guided combat modules from SAAV, modern full-fledged German electronic warfare MASS with traps of all types.
    GAS Kongsberg ST2400 VDS is designed to detect submarines, mines and unmanned underwater vehicles in coastal waters, will create an anti-submarine potential in all four Hamina-class units operating in the Baltic Sea. According to the company, the VDS ST2400 is a mid-frequency sonar designed with an emphasis on shallow water operation, featuring a compact design (less than 3 tonnes). “The Finnish Navy has been our key partner since the development of the first ST240 VDS sonar in the 90s, to the latest version of the ST2400 VDS that we have today,” says Thomas Hostvedt Dale, Sales Director of Kongsberg Maritime Subsea Naval. “This equipment has been tested in the difficult shallow water conditions of the Baltic Sea, where reverberation and layers are dominant.


    With air defense, however, the sources differ.
    Initially there were Umkonto, when they started modernization, it was about ESSM, but the sources write that the Umkonto remained, but they were modernized.
    Umkhonto-IK Block 2 This variant of the IR Umkhonto was recently developed in cooperation with the Finnish naval forces. It has a more advanced finder head algorithm to distinguish between target clutter and background clutter that are common in and around the Baltic archipelago. Thanks to the improvement of the seeker, the new version has a more efficient flight path, which allows to increase the flight range by 3 km (1,9 miles); new maximum range of 15 km (9,3 mi). Its current flight ceiling is 8 km (5,0 mi). Denel Dynamics has announced its intention to discontinue production of the Block 1 rocket and continue production of the Block 2 version of the rocket as part of the overall rocket development path. The extended-range version of Unit 2 of the Umkhonto-IR variant was tested in October 2013. During the demonstration, three missiles successfully destroyed low-cost aerial target systems (LOCATS - provided by the South African army), two - at a distance of 15 km. range and one per 20 km. The targets were launched from the Denel Overberg test site and flew out to sea, and then turned towards the coast in an elliptical trajectory. Successful ground fire tests have proven that the Umkhonto's range can be increased to 20 km with the same physical dimensions of the missile.

    Umkonto has a two-spectral IR seeker with target acquisition after launch and radio correction of the flight.
    Add to the fact that the boats are capable of placing modern Finnish mines - and it is clear that the boats turned out to be very serious ...

        Well, with such a displacement, you can turn around.
        In my understanding, a light-alloy / high-speed boat is less than a hundred tons (ideally, it must be hydrofoiled). Otherwise, he will not be able to give more than fifty km / h on the water.
        A boat with such a displacement will give a maximum of 50 km / h.
