Italian Porcupine: SAU Centauro 155 / 39 LW Porcupine

27
2 June 2011 was held in Rome, a military parade dedicated to the 65 anniversary of the proclamation of the republic and the 150 anniversary of the unification of Italy. During this event, not only combat vehicles in service were shown, but also several prototypes of advanced equipment. At the parade, the prototype of the new Centauro 155 / 39 LW Porcupine (Porcupine) prototype was demonstrated for the first time. The Porcupine ACS is another combat vehicle based on the Centauro chassis, already used in several armored vehicles projects. In the near future, in connection with the decommissioning of old equipment, the main self-propelled artillery installations of the Italian army will be the German-made PzH 2000, assembled under license in Italy. The Porcupine ACS is created taking into account the need to supplement and then replace foreign equipment and preserve the combat potential of artillery.




The new development of the CIO consortium, which includes Iveco Fiat and OTO Melara, is based on a modified “wheeled” chassis tank»B1 Centauro. The 8x8 chassis is equipped with bulletproof armor similar to the Centauro base car. When creating a new project, the original armored hull underwent minimal changes associated with increasing the level of protection against mines. The Centauro 155/39 LW self-propelled guns are equipped with an Iveco MTCA 520 hp diesel engine. Such a power plant in combination with a wheeled undercarriage provides a 25-ton combat vehicle with sufficiently high running characteristics. On the highway, the Porcupine self-propelled gun can accelerate to a speed of about 100 km / h and overcome up to 800 kilometers at a single refueling. It is easy to see that the mobility characteristics of the new self-propelled guns remained at the level of the “wheeled tank”, which served as its base.

In the rear of the armored hull, as on the original B1 Centauro, the Porcupine ACS is equipped with a rather large turret with a weapon. When you first look at the promising Italian SAU, your eyes linger on the turret with the original gun mask. Both the tower and the mask are assembled from several straight metal sheets, which gives them a distinctive appearance with many straight edges. In addition, the gun mask has a much larger size than similar units on existing self-propelled artillery installations. The reasons for the use of such an original tool mask were not called.

The design features of the tower and the chassis led to specific capabilities for the guidance of guns. Systems inside the turret can raise the howitzer barrel to an elevation of 75 ° from the horizontal and lower it to 5 ° below it. At the same time, the tower has limited horizontal guidance angles: due to the peculiarities of balancing the chassis and the machine as a whole, as well as due to a number of other structural moments, the tower turns only 15 ° to the right and left of the longitudinal axis of the self-propelled gun. This greatly limits the combat capabilities of the machine when working at the front edge, but it has almost no effect on shooting from closed positions, for which it is primarily intended. The same can be said about the time required to transfer the car from a traveling position to a combat one. The first shot is possible three minutes after arriving at the position.



The main weapon of the Porcupine self-propelled artillery gun is the 155-mm howitzer FH70 with barrel length 39 caliber. The gun has a large muzzle brake with a large number of round holes. Allegedly, using Centauro 155 / 39 LW active-projectile launchers can hit targets at a distance of up to 60 kilometers.

Perhaps the most interesting part of the Porcupine project is the internal equipment of the gun turret. The fact is that the SAU crew consists of only two people and is located inside the armored hull. The tower, in turn, is uninhabited. The howitzer comes with a fully automatic loader system that provides a firing rate of up to 8 shots per minute. High rate of fire is compensated by a small ammunition. In the autoloader packs, there are just 15 shots, which accordingly affects the practical rate of fire. Because of this, the developers suggest using Porcupine ACS together with a transport-loading machine on a similar chassis. After the spent ammunition is used up, the self-propelled gun can get new projectiles within 8-10 minutes and in about a minute again open fire. The ability to feed shells from the ground, according to some sources, is not provided.

The Centauro 155 / 39 LW ACS can use the entire existing NATO nomenclature of 155 millimeter shots. In addition, the company OTO Melara in recent years has created several new types of shells of this caliber, differing from each other in the applied systems. In the line are unguided and guided munitions, including active-reactive. The latter include the stated maximum firing range of 60 kilometers.

Self-propelled howitzer is equipped with a digital fire control system that allows you to automatically carry out all the necessary calculations. Among other things, the self-propelled gun self-propelled guns Porcupine can, without the operator’s participation, fire in MRSI mode (a so-called barrage of fire) with a volley of up to four shots. For about 25-30 seconds, the SAU makes four shots with different charge and barrel elevation, with the result that all the shells reach a common goal with a minimum time interval.

Italian Porcupine: SAU Centauro 155 / 39 LW Porcupine


After the demonstration at the June 2011 parade, the prototype ACS Centauro 155 / 39 LW was shown to the general public several times, but none of the shows were accompanied by the disclosure of the desired amount of information. So, for example, it is still not clear at what stage this project is currently located. Judging by the lack of deliveries of serial combat vehicles to the Italian army, the prototype of the promising self-propelled gun is still being tested and refined. At the same time, less positive options cannot be ruled out. Due to the limited targeting angles and small portable ammunition, the Porcupine ACS is an ambiguous development in practical terms. The specific correlation of characteristics and fire capabilities (when using the latest ammunition) can lead to any completion — both to the beginning of the serial construction of combat vehicles, and to the suspension or even complete closure of the project.

    52 caliber PzH 2000 shoots APC somewhere at 40km, and they have a record at 56km. Italians at 39 gauge declared all 60km. Who is more? This is probably the reason for the handouts. smile

        No kickback (at least I didn’t notice).

        The recoil devices are probably hidden, either under the guise of a gun or in a tower (since it is uninhabited and the ammunition is only 15 shells, there should be enough space there).

          Look carefully at the picture where the gun looks into the “sky”; look there, in the “windows” of the mask, some “pipes” are clearly visible. In general, a picture with a higher resolution obviously would not hurt.

            These are not recoil devices. the angle with the barrel is different. most likely these are hydraulic jacks.

      155mm gun is not a sniper rifle "2 minutes shot and leaked."
      will not go.

      then there are 15 charges and then charge from a special installation and the projectile should not be fired from the ground
      it is purely in the Italian spirit:

      we made this beautiful building and the rest is your problem.

      I allowed myself such a categorical assessment
      So the following parameters were enough for me:

      “There are only 15 shots in the stacks of the automatic loader”
      "Because of this, the developers propose using the Porcupine self-propelled guns with a transport-loading vehicle."
      "get new shells in 8-10 minutes"
      "The possibility of delivering shells from the ground, according to some sources, is not provided."

      Centauro 155/39 LW Porcupine

      1000 shots takes: 125 minutes
      + 66 reloads of 10 ten minutes each. : 666.6 minutes
      total: 791.6 minutes


      M109AL

      1000 shots takes: 250 minutes

      what is the comparison?

    At one time, during the "peacekeeping operation" in Somalia, Centauro was extremely vulnerable to mines and RPGs. As a result, they were used mostly at stationary checkpoints.

    Something to me this "clunker" does not resemble a porcupine but some extinct trunk-mastodon? or tapir, by the way, and someone can explain what kind of “pipe cuts are visible at the bottom of the gun’s mask, maybe by understanding from what they will understand the size of the mask, and with regards to the contours, it’s an ideal target or any rebound.

      If outriggers (when shooting from closed positions) will unload the tower, and not from the chassis of the car, then I think that's enough.

    8 rounds per minute is somewhere 8 between shots.
    I wonder what happens to the 25t car on a wheeled chassis
    when firing an 155mm projectile? I think the buildup should be very
    strong and this is only a technical rate of fire.

      Italian Porcupine: SAU Centauro 155 / 39 LW Porcupine

      I think the Italians wanted to create something similar to the Swedish self-propelled guns ,, Archer ,,.
      But the idea clearly failed. And with a barrel length of 39 calibers, declaring 60 cells is fantastic.
      And the base for the gun, in the form of a Centauro 8/8, is clearly weak.
      The Swedes made their platform on the basis of. At the base, Volvo - articulated dump truck, are used in construction and quarrying. The capacity of dump trucks is from 20 to 40-50 tons. They possess high maneuverability and cross-country ability.

          Good evening PLAIN. Cool video. Beautifully run.
          Now in the West and in Asia there are many similar art .. systems.
          But it all started with the South African G-6. Development began in the early 1970s at the state corporation APMSKOR, and the first prototype was built in 1981.

          And in the Czech-Slovak Republic. In the mid-1970s, the artillery system adopted by the Czech-Slovak army under the designation 152 mm ShKH vz.77 was developed at the design bureau of a machine-building enterprise in the Slovak city of Dubnica nad Wag. Launched in a series in 1979, under the name - ,, Dana ,,.
          All-wheel drive chassis Tatra 8/8 was used as a chassis for self-propelled guns.

          Before the appearance of these 152 and 155 mm howitzers, all self-propelled guns of this caliber had a tracked chassis.

            I won’t say anything about the Yuarovskaya one because I don’t know what about the “Dana”; its central location of the tower is less than the length of the “Porcupine” barrel. Moreover, when firing, 3 hydraulic bearings extend and her tire pressure decreases to reduce the load on the wheeled chassis.

                The peak of the development of "Dana" was "Zuzana" (also a woman’s name). But it seems that no one else mounts a 152/155-mm howitzer in a tower on a wheeled chassis. Here are just these two countries (South Africa and Slovakia), well, Italians with this absurdity.

                    Taken out of context. I talked about tower placement. In those self-propelled guns, the chassis plays the role of a counterweight. This is a more reasonable solution.
                    PS Although accept my notices, the Serbs still placed a 155-mm howitzer, whose recoil force falls on the chassis. But they released a minuscule.

    ambiguous art system. 2 people crew is cool. but it’s bad that the tower rotates horizontally 30 degrees. and the stock is small 15 shells. although how to look at it. 40 shells are also not many.
