Israel has developed a new wheeled self-propelled howitzer SIGMA to replace the American M109

July 31 2021 60

The Israel Defense Forces will soon receive a new 155 mm SIGMA wheeled howitzer. According to Jane's, the introduction of the ACS into service is planned from 2023.

The new howitzer was developed by the Israeli company Elbit Systems as part of a contract received from the Israeli Defense Ministry in 2019. The wheeled self-propelled gun is intended to replace the self-propelled howitzers on tracked M109 series in service in the Israel Defense Forces. It is planned that she will go to the troops from 2023, where she will receive the official army name Roem.

The howitzer is made on the automobile chassis of the American company Oshkosh with the formula 10x10. Caliber 155 mm, barrel length 52 caliber. The gun, equipped with a muzzle brake and an ejector, is located in an uninhabited fully automated armored turret. At the same time, there is a mode of manual feeding and loading of shells. The calculation itself consists of two or three servicemen, placed in the front armored cabin, which has protection against weapons of mass destruction.

According to the bmpd blog, the ACS has an automatic loading system, consisting of two stores, one of which feeds shells, and the other - modular charges Uni-Modular Artillery Charge System (UMACS) developed by Israel Military Industries.

To date, the main characteristics of the 155-mm / 52 self-propelled howitzer SIGMA are not disclosed.

      Self-propelled guns are used not only for howitzer firing, but also for direct fire, including shrapnel shells at enemy manpower. For such special occasions, it is better to have a low silhouette and a tracked track. These requirements are met by 122 mm Carnation and 152 mm Acacia, the former also floats.

    Aaron! Wheeled chassis have their own advantages. In the conditions of Israel (most of the year - dry!), They are quite normal for themselves .... Here - the most important thing - the speed of deployment / folding ...... With tracked chassis - it is a priori less! But in the presence of good roads - a wheeled chassis has advantages. Besides, it (wheeled chassis) is much cheaper!
    PS In the conditions of Russia, BOTH options are needed: tracked and wheeled! Moreover, we have learned to build GOOD roads, thank God!

        Come on. One demon came to the same thing, only much later. And the imaginary savings on the purchase of the M109 were eventually covered by the costs of developing our own, kosher self-propelled guns. Again, we decided to save money by washing down the wheeled version, but on the other hand, there are more export opportunities, because the demand for wheeled self-propelled guns will be wider. The price tag of this device has not yet been indicated, but in any case it is not more expensive than money. By the way, they acted correctly, retaining the Bashner’s lamp option - here the prospects with a potential clientele from the curtain metropolis are already looming.

Wheeled artillery systems are gaining popularity today because they are mobile and can travel on public roads. They also weigh less, which means they are not as dependent on transporters for transportation over long distances as tracked ones.
In the front armored cabin of the SIGMA howitzer with a system of protection against weapons of mass destruction and full air conditioning, two or three people can fit. The firing part of the system will be located in an uninhabited automated armored tower, which can be controlled remotely. The volume of the gun's charging chamber will be 23 liters.

It would have been a 155 caliber Dana, I think it would have been accepted, with the Israeli LMS. It looks more stable than the new one in the picture.
But God forbid it topple over. I'm glad for my friends.

It is also interesting that with the modern ATMOS 2000, which Israel advertised well (there is a good video of shooting on YouTube), sold to others, but did not accept it into the troops?

  It served as the basis for the Roeme, which will be a much more expensive weapon than the ATMOS due to its fully automated loading.
  By the way, Slovakia is now adopting the "Zuzana 2" self-propelled guns, made on the basis of "Dana", but with a 155mm barrel for 52 caliber.
  
  By the way, the self-propelled gun "Zuzana 2", as you see on the 8 × 8 chassis, and Roy is planned for 10 × 10, so it will be quite stable, but I would still prefer a tracked platform.

Not even funny ...
The point there was not Dan's ACS, but the Georgian army and the situation in which it found itself. If there were Georgians, the same Czechs, the situation would be the same - you remember who and whose army the Grrrruzin army and its great commander-in-chief faced Georgia had no more than a VAZ Oka chance there against a 150 ton mining dump truck

The same self-propelled guns Dan and in the same Transcaucasia literally last year were successfully used in the war by the Azerbaijanis. These wheeled self-propelled guns modernized by the Israelis and Israeli self-propelled mortars on a Mercedes wheeled cargo chassis and Plasan Sand Cat armored vehicles, judging by last year's video clips, were used very intensively in the south.
