American 155-mm self-propelled howitzer XM2001 Crusader

51
Crusader 155-mm self-propelled howitzer was developed for the US Army to replace Paladin. It was assumed that the United States Army would need some 800 self-propelled guns. The Crusader program in May 2002 goals were officially terminated by the Ministry of Defense, because Crusader was considered insufficiently accurate and mobile in the light of the requirements of the XXI century. United Defense in August 2002 received a formal notification, which stopped all further work on the program. At the same time, United Defense received a contract to use the technologies developed for the Crusader program to create a new Objective Force Cannon (Tools for Advanced Forces) or tools for firing non-Line-of-Sight indirect firearms (NLOS). “Prospective Forces” is the working title for the long-term program of the future United States armed forces.




Crusader's test firing at the Yuma range (Arizona) began in February 2000. In November of the same year, the 10,4 firing rate per minute was achieved. In November 2001, a preliminary design assessment (PDR) was conducted. Start of production was scheduled for 2006 year, and the adoption of Crusader into service was planned for 2008 year. Crusader was developed by Team Crusader under the leadership of United Defense.

It was assumed that the Crusader artillery system would provide better mobility, efficiency and survival, and would also be much easier to maintain and deploy than the existing systems. A battery from 6 Crusader can deliver 15 tons of ammunition to the target in less than 5 minutes.

To achieve these characteristics, United Defense has reduced the weight and size of the crusader — from the initial 60 tons to the 38 –41 tons. This made it possible to simultaneously transport 2 howitzers by C-17 or C-5 aircraft. Thus, the use of a self-propelled howitzer Crusader for fire support was facilitated.

The Crusader includes two vehicles - a self-propelled howitzer XM2001 and an armored transport and loading machine XM2002. The high level of automation makes it possible to reduce the crew of both a loading machine and howitzers to reduce to just three people. The process of loading and firing is controlled from a computer-equipped cabin, which is hidden under the armor and has a protection system weapons mass destruction. The armored transport loader has not only a tracked but also a wheeled variant.



Self-propelled howitzer XM2001

The XM2001 howitzer is equipped with a fully automated loading and firing system, which makes it possible to shoot 48 projectiles (full howitzer ammunition) with a maximum speed of up to 10 rounds per minute over 40 thousand meters. 15 seconds are required to produce the first shot. In addition, Crusader can produce a series of shots with a simultaneous hit on the target shells. One Crusader machine provides simultaneous hit on one target to 30 projectiles. The digital fire control system calculates the solution separately for each of the 8 shots.

XM2002 transport loading machine

The Crusader howitzer ammunition is replenished with the XM2002 transport loading machine, which is equipped with a fully automated loading subsystem. This subsystem enables the crew of the HM2002, consisting of an 3 man, to replenish the fuel supply and load 48 shells into a howitzer in less than 12 minutes. without leaving armor protection. Loading can be performed in the conditions of bacteriological / chemical contamination. It takes less than 60 minutes to load the transport vehicle with projectiles and fuel.

Command and control

The Crusader command center is equipped with tactical systems that provide assistance in decision making, navigation and positioning, and an automatic friend-to-friend recognition system.

The Crusader control system sends and receives real-time battlefield data using the Advanced Field Artillery Tactical Data System (AFATDS). Crusader can communicate with other machines directly. A secure information transmission network links a howitzer, a loading vehicle, as well as all other combat units on the battlefield, transferring real-time data to each machine in real time.



Armament self-propelled howitzer Crusader

For Crusader shooting, all types of projectiles are used, including high-explosive fragmentation, smoke, incendiary (with white phosphorus), dual-purpose cluster anti-personnel and anti-tank (DPICM) and anti-tank cluster projectiles (Sense and Destroy Armor, SADARM).

Artillery subsystem Crusader used solid propellant. It consists of the actual instrument, machine and laser charge ignition system. The extremely high rate of fire is ensured by the integral cooling system of the barrel of the cannon between the double walls. To minimize wear and environmental impact, the barrel of the gun and charging chamber are coated with chrome. The gun charge chamber is compatible with MACS (Modular Artillery Charge System), which use solid propelling agents.



Engine and suspension

Hydropneumatic suspension and the Crusader engine provide highway traffic at speeds up to 67 km / h, over rough terrain - 48 km / h. The transmission allows you to select the gear ratios and the mode of the engine in automatic mode for maximum fuel economy. The control system consists of electronic motion control, as well as assistance in motion planning and positioning.

The U.S. Army has selected General Electric and Honeywell International Engines as developers for the Crusader LV100-5 gas turbine engine. They wanted to use the same engine for tank M1A2, as part of the Abrams / Crusader single engine program. The new engine was supposed to be smaller and lighter, with faster acceleration, no visible exhaust and less noise.

      Maybe it’s all about the elevation angle and different charges in weight and not the length of the barrel?

        Yes. And in the presence of a large number of hinged and flat trajectories associated with this. Roughly speaking, they can work both as howitzers and guns. And even like mortars, with mortar (more than 45 degrees) shooting.

        There are no special differences between the “crusader” and the “donar”.
        Approximately the same weapon, about the same electronics, modular loading and shooting only from the combat station.
        The difference is that Krusader has a lower tower due to the fact that part of the mechanisms is located in the case, and at high elevation angles the breech goes down there. And there is a transport-loading machine, which is a clear plus.
        At Donar, everything is located in the tower itself, which allows you to put it on any base, up to stationary placement on a concrete slab. The minus is the high tower and only the manual loading of shells and charges in the combat unit

          The key plus of Donar is precisely modularity. Can be placed on many suitable chassis. And the weight of the installation itself, in my opinion, is 15 tons, which is less than the Crusader.

      This is a howitzer. The product of the evolution of artillery systems in the pursuit of greater range. The cannons rested in a Bose, and for shells two maximum ranges are now officially given - for "short" and for "long" howitzers.

      By the way, even before World War II, classification by the length of the barrel was abandoned. We switched to classification according to available trajectories.

      Quote: Canep
      Fire rate - 10 rounds per minute. Impressive.

      Than? Standing in service with 2S19 - 8 rounds per minute. Her latest modification is 2S19M2, equipped with an automatic pickup recovery system, according to various sources, 10-12 rounds per minute.
      The expected “Coalition” with the same modular loading as the “Cruzader” will naturally fire even faster. Limit will no longer be the installation capabilities, but the possibility of overheating the trunk.

          Like that. A projectile flying along a steeper trajectory with a higher speed will take more time than flying at a smaller angle with a smaller one. So to choose a fire mode in which several shells arrive at the target at the same time is quite simple.

    Of course - a howitzer. Separate loading is the main indicator (guns and howitzers are also called guns in artillery). It is this technique that we need. It is clear that this system will be further developed. But the principles that are already laid down in it are really impressive. Although, there are questions:
    - what ammunition is transported by TZM;
    - whether loading the gun "from the ground" is provided;
    - the barrel mount beam is unlikely to withstand such a trunk when driving on rough terrain at a decent speed ....
    These questions "offhand" according to the meager information that is given in the article and in the video ....

      You are mistaken. The 2A36 gun not only has separate loading, but also 4 (as far as I remember) charges. Full, reduced, first and second.

          Find at least one artillery gun with a caliber of more than 105 mm with unitary loading. It makes no difference whether it is a howitzer or a cannon. Only the weight of the shot matters. Large calibers - separate-sleeve, cartridge or modular. But never unitary

                and what fundamentally differs D-25T from A-19 and D-25-44 so that the latter suddenly ceases to be an artillery gun?
                all these guns could be successfully installed (and the first two were placed) on self-propelled guns.
