About the problems of the US Navy Zumwalt destroyer and the testing of the new Mk 46 Bushmaster guns

24

The new American ship Zumwalt conducted the long-awaited tests of its artillery weapons. The installation of new guns on the destroyer, which took place a little over a year ago, caused quite an active discussion. Now these guns fired for the first time.


Mk 46 instead of Mk 110


We are talking about 30-mm Bushmaster guns, which were previously installed on landing vehicles such as San Antonio. Recall that at first the Zumwalt destroyers were going to arm with much more powerful 57-mm guns, but in the end they chose the Bushmaster. Almost all standard types of ammunition 30x173 mm, which are manufactured according to the standards of the North Atlantic Alliance, are suitable for these guns.

Tests of the new weapons of the destroyer were conducted on May 16, 2020 at a test site near Cape Mugu in California. The captain of the Zumwalt ship, Captain Andrew Carlson, said that the possibility of conducting systematic tests of weapons installed on the ship is related to the privilege of the ship as the first in its class.

Two Mk 46 Mod 2 Gun Weapon Systems (GWS) are installed on the helicopter hangar of the ship. Each Mk 46 Mod 2 is a remotely controlled turret with one 30 mm Mk 44 Bushmaster II automatic cannon. The operator uses the control console to aim. weapons, relying on the help of infrared video cameras, an integrated laser rangefinder inside the tower and other equipment. Such guns are effective against small surface targets, for example, enemy boats, especially if they operate in a swarm (by the way, according to tactics tested by Iran in the Persian Gulf).

Meanwhile, the artillery weapons of Zumwalt a few years ago was the subject of fierce debate within the US Navy command. At first, as we noted above, it was planned to install larger Mk57 110-mm guns on the ship. But in 2012, the naval command opted for the Mk 46 GWS, arguing that it was these guns that would be optimal for the destroyer.

Interestingly, the Mk 110 cannon has more advantageous characteristics: a greater firing range, a higher rate of fire, a wide range of ammunition used, including "smart" shells. That is, the installation of the Mk 110 would really improve the combat capabilities of the ship. In addition, the MK 110 would be more secretive when installed on a ship. For example, if you look at Swedish Visby class corvettes, the guns installed on them are practically invisible to the enemy. But the command stopped at the Mk 46 GWS.



Zumwalt Weapon Issues


Apparently, financial considerations played an important role in making such a decision, since Zumwalt cost the US military budget so expensive. This decision, according to some experts, significantly worsened the stealth of the ship, although at first the US Navy very actively talked about the need to use the stealth factor for the new destroyer.

Now 30 mm cannons are also the only active weapons of large caliber Zumwalt. Indeed, in 2016, the Navy command canceled plans to acquire long-range long-range projectiles (LRLAP), paired with two 155-mm main guns of the destroyer. This decision was made after increasing the cost of shells. The U.S. Navy is studying other types of ammunition that could be used on main guns, but so far the main guns of the ship are not functioning.

The consequence of armament problems was the fact that the Zumwalt ship, officially commissioned by the U.S. Navy in 2016, was banned by the U.S. Congress for delivery until the armament systems were activated.

Tests had to wait four years and only now Zumwalt is gradually entering the US Navy. Despite the great future that American analysts predicted for him, the real Zumwalt destroyer, if you think about the four-year delay, continues to raise questions.

You can also take a look at an earlier video that shows how the Mk 46 cannon works.

      They have a main 155 mm. But, in connection with the reduction of the Zumvolt program, everything hung.
      A few years ago there was infa that the cost of a LRLAP guided projectile for this gun began to approach $ XNUMX million. But people work, sawing twenty years. laughing

          on the one hand, yes, there is a destroyer and there are problems, but on the other hand, there are no problems (actually there are), but there is no destroyer either ..

    Obviously, with this "iron" is all! they will no longer invest in this project.

      "Zamvoly" in fact became demonstrators of technology, a kind of "floating laboratories." So they will be redone in the future, and more than once. It is for testing any new systems. That is precisely why it is now completely unimportant to the American admirals what to put on them at the moment - the main thing is that you can enlist in the fleet as an already fully operational unit. And there already in the process of operation and arrange all sorts of experiments. With the same ship combat lasers, for example.

    And what? The enemy, seeing such a ship, not seeing the gun, should take it for a merchant ship? belay

        visual visibility and visibility in the radio frequency spectrum are two different things.
        In the first case, they (guns) are masked in superstructures. And in the second case, this disguise is not needed. The main thing is to remove everything in the tower with the correct angle of inclination of the walls to reflect the incident signal away from the emitter. Plus absorbent materials.

    That is, USN on fancy technology demonstrator returned from ZAK with guidance from the radar to small-caliber artillery with remote guidance by the operator? They would have set up the targeting columns, amateurs save money. smile
    Why was standard R2D2 bad for them?

    millimeter guns, but ultimately opted for the "Bushmasters." Almost all standard types of ammunition 30x173 mm, which are produced according to the standards of the North Atlantic Alliance, are suitable for these guns.

    And why not immediately 5,56x45 mm? They are also produced according to NATO standards. And taxpayers would have been even cheaper.

        the reason for this is ATT troubles in the near-surface layer (where our M15 works fine), see:

    What were the weapons of those ships that participated in these wars? It was large-caliber, and the artillery of the ship fired an indescribable amount of shells. Why? For the simple reason that the percentage of hits in the First World War was less than 2%. That is, hundreds of tons of shells just sowed the sea. What has changed for the next World?
    Rangefinder posts, which were also in the First, began to give data a little faster and slightly more accurately. So the percentage of hits increased slightly, somewhere 3,6%. The same thing - a lot of shooting, a little sense. And now? And now everything has changed IN PRINCIPLE. Generally. Absolutely.
    The fact is that to find out the range to the target and the direction to it is enough for land artillery. Land guns, having these data and not too big shots, will achieve hits of more than 90% easily. And it’s pumping into the sea, both your cannon and your target. But something appeared here. A little bit. In general, now you can achieve 50%, or even more.
    For the simple reason that modern computers, capturing the target and analyzing all the data, both on the movement of the target in three planes and on the movement of your own ship, can quickly give really all the information you need. Increasing the percentage of hits dozens of times. It is now, finally, that naval artillery, for the first time in history, has become truly effective.
    No wonder everyone abandoned it) Left a miserable 30mm spit. Eric Frank Russell carefully and thoroughly examined all the twists of the amazing military mind ...

      electromagnetic did not finish to the condition of installation on the destroyer. A shot from E-Gan is many times more expensive than from a conventional ship’s gun. And they have a rate of shitty TC. it is necessary to accumulate momentum + rapid wear of the barrel (rail, guides)
