New armor and Belgian cannon: Indonesia intends to modernize amphibious tanks PT-76

47

Soviet floating Tanks PT-76, produced in 1951 - 1967, for a long time managed to show worthy service in the Asia-Pacific region, in particular, taking an active part in the Vietnam War.


Currently, these vehicles continue to be part of the armies of a number of countries, including Indonesia. The military of this country, which has a long coastline and many islands, traditionally focus on floating technology. In this regard, within the framework of the modernization of the armed forces, the possibility of improving the PT-76 fleet is being studied.

As the command of the Marine Corps reported on January 27, the implementation of the program for the improvement of Soviet amphibious tanks continues. KMP intends to raise them to a new technical level. It is assumed that the upgraded PT-76 will receive a 90-mm cannon (the option of equipping a turret with a Belgian LCTS 90MP cannon is being considered), optoelectronic filling, improved protection (including by strengthening armor), a fire control system, an electromechanical part will be updated and fire extinguishing equipment, will receive an improved engine, drives, hydraulics and water jet propellers. The new version of the tank has already received the designation PT-90RI.

According to the IISS, 15 PT-76 units are currently serving in the Indonesian army, and 55 vehicles in the Marine Corps. It is quite possible that the Russian defense industry will take an active part in the modernization of this park, among whose priorities is traditionally floating equipment.

      The only question is, will it float after such an upgrade?
      With reinforced armor, a more powerful and heavier cannon and ammo for it?
      But as a platform, he is still quite nothing.
      By the way, instead of the Belgian cannon, a 100 mm gun could be proposed. from BMP-3 - and the caliber is larger, and the rocket shoots, and the weight, as it were, is not lighter.

        Unlikely. The Belgians have a low-impulse weapon, which, figuratively speaking, even put on a bicycle. It is lighter, although it loses in terms of armor penetration and high-explosive effects.

          Ours would have stood up completely and would have been more interesting, but they seem to be closer to Belgium - they will not impose sanctions on it.

              Or maybe ours simply did not show the initiative. Or they even refused to modernize such an old pepelatsa, because we are supplying BMP-3 there. And they are very happy there.
              Maybe ours just didn't want to separate the module and separately 100 mm. adapt the cannon to a tower that is alien to her. It's OCD, hassle.
              Why, if you can offer brand new BMP-3s, which have proven themselves VERY well there?
              But these are only assumptions.

        Why fence a vegetable garden when BMP-3s are approximately equal in armor to PT-76s, but in terms of combat qualities they are many times better. She only lacks a panorama with a teplak.

          I cannot compare them, because the seaworthiness of these products is unknown, but I note that combat vehicles have many more different hatches and places where water can seep. That is why a "clean" tank wins in this respect, especially if it comes under fire in the water.
          I think. that we need to somehow secure guaranteed orders from several countries, and urgently modernize our PT-76 for new weapons (more precisely, create a new one using some of the solutions of the past) so that we can fill this niche in the arms trade.
          Yes, and inside the Armed Forces, we might need to revise some established traditions from the point of view of the development of our armored vehicles for different situations, and not rely only on BMPs.

            The Indonesians also have BMP3 and the same PT-76. They operate both machines very successfully. Moreover, when disembarking from a landing ship through a flooded dock. It will definitely not work to fence the Bakhcha combat module on the PT-76 hull. It is banal that the pagon of the tower is narrower than that of the BMP-3. Again, the BAKHCHA moldul has a much greater mass than the native PT-76 tower and it needs much more power supply.
            By the way. Indonesians are happy to drool by 3rd Behoy.

              Is it really about the entire combat module?
              The Indonesians want to keep the PT-76 in service, but to increase the caliber of the gun and modernize it in general. Therefore, I wrote that it is much more profitable to install a gun (100 mm) from the BMP-3 than to install 90 mm. cannon from another manufacturer. Here is the unification of ammunition, and the greater power of the shells, and the possibility of firing missiles. After all, it is much more profitable to have one weapon for two different combat vehicles than to produce a zoo. Yes, and for the money, it would be more profitable with us.

    So, they say and write a lot that light tanks are selling well on the world arms market, that China is the leader in their sales, and I am sure that we must create at least for export such a tank, moderately inexpensive and competitive, with good protection, high cross-country ability, and strong weapons. We do not have a light single-engine fighter, and this is also a money segment of weapons on the world market, we do not have a light export tank, and we are also losing good money!

      to model the T-64 and T-62, according to the new classification, they are suitable for light weight, do not have cardboard armor (most light tanks are infantry fighting vehicles with a large-caliber cannon), and a gun of a larger caliber than most of them (most often 105mm).

      The Type 63A amphibious tank began to arrive in the units of the Chinese marines and in the amphibious units of the Chinese ground forces in 1997. It has 105 mm. a rifled cannon with a low recoil impulse, equipped with a muzzle brake and a gas ejector, the latter for reducing the gas content of the tower. It was based on the British L7 cannon.

    PT-76, produced in 1951 - 1967
    And long standing in service and our marines. The school studied this tank, like other tanks, infantry fighting vehicles and armored personnel carriers that were in service at that time. In 1976-79 he had to participate three times in joint exercises with the marines (we were in favor of the enemy). Feedback from them about the PT-76 was only positive. The same chassis was used on the BTR-50 PC.

      With 57mm cannon.
      ".... The gun is equipped with an automatic loader. The automatic cannon's rate of fire is 120 rds / min. The full ammunition reserve is 70 rounds in armor-piercing tracer and fragmentation tracer versions.
      The effective range of the cannon for enemy tank vehicles is 1000 meters, and the BTR and BMP are 2500 meters. The application range for enemy air objects is up to 4000 meters.
      The range of the Kornet missiles is 5000 meters. Penetration - up to 120 centimeters.
      Not ignored the characteristics of mobility. The PT-76 can be equipped with a powerful 420 hp propulsion system. This will qualitatively raise the main speed characteristics of the PT-76. The speed of overcoming water obstacles will increase to 14 kilometers per hour ..... "

    Will the original model have enough buoyancy for all these Wishlist? In the above picture I can already see that the new tower is much larger than the old one. The size and weight of the gun too. This means that the tank afloat will receive an increased front end differential. It means that it will become stronger to burrow into the wave. Turning the turret and firing sideways while afloat also become questionable due to the fact that when turning the turret, the tank will begin to sausage in the transverse direction. For the weight of the weapon and the length of the barrel are the "lever".
    Or the Indonesians will attach floats to him on outriggers to calm the pitching? Like on Polynesian catamarans.
    Can anyone clarify who is more in the subject? What is the buoyancy of the original model?

      so doubts come to my mind, precisely in the area:
      improved protection (including due to increased armor)
      , plus the impulse when firing from the "Belgian" LCTS 90MP is higher than that of our 76th (and if an onboard shot .., or will use water cannons along the course ...), it is unlikely that they will calm down with additional floats on the sides, and the dampers there not stick in lol , and the total mass will be higher again !?

        This is just for fun.
        But burying the nose into the wave due to the increase in the trim on the nose. Taking into account that they do not have lake navigation, but quite a sea one, between the islands. With no river / lake waves at all. Offhand, I see only swimming with the tower turned back. To correct the weight distribution a little. Well, all whistles-pe ... ki will increase the draft. This means that at the slightest excitement, the water will roll over the tower. However, the snorkel must be installed. And this ... like him, periscope. lol

    because the seaworthiness of these products is unknown

    known - recently tested in the Kerch Bay.
    the conclusion is simple - even in a calm sea there is only buoyancy, there is no seaworthiness.
    they can swim relatively normally only on lakes without waves - even Ladoga is too dangerous,
    On the test - yes, the tank can swim and even beautifully, but this is very unreliable, the cars are poorly protected from flooding and other problems. The statistics of losses when trying to swim speaks for itself.
