Israeli M50 155mm self-propelled howitzer

The M109 self-propelled howitzer was developed by the Americans and has been variously developed since its inception in the 1960s and exported to various other countries.

The M109
You can't talk about the M109 without looking at its closest relatives. The closest relationship is with its older sister, the M108, while the M107 and M110 can at best be viewed as cousins, as they emerged from a different conception. Of course the 4 vehicles are based on the same concept as self-propelled artillery cannons, but the M107 and M110 are cannons on an open chassis, a bit like the AMX10F3, while the M108 and M109 have the cannons in a closed turret, like the AMX30 AUF1. In addition, the calibers are different 170 to 203mm for the M107 and M110 105 to 155mm for the M108 and M109. Chronological consideration of the weapon systems:
The construction of the weapon systems began at the height of the Cold War and even more specifically during the Korean War, when it was decided to replace the M44 with a 152mm caliber with a new system family. The US Army has specified specifications for the construction of two artillery systems on the same frame: one with a large and one with a smaller caliber. The light should be between 110 and 156mm and was later set to 105 and 155mm, as the US Army still had large stocks of ammunition of this caliber. In addition, NATO had to standardize weapons and ammunition. The M107 and M110 should then accommodate heavier calibers.
The manufacturer Cadillac was chosen for production and this was later taken over by Chrysler.

M108 and M109:
The standardization of these two vehicles involved from the beginning to use the same chassis and turret, which were taken from the T195 prototype with the 110mm cannon. To reduce weight, the armor was reduced to a minimum. Although they are not amphibious, they do have a certain ability to swim. They can also be transported in a C130.
The future M108 (T196) production was to start in 1959. Immediately there were problems with the suspension and the diesel engine that needed to be resolved. This delayed mass production until 1962. After the start of production, the US Army found that the caliber was too small and withdrew all produced units from the front, where they were only just being used in Vietnam (June 17, 1966 in Pleiku the 3 / 6th Artillery as the M109 in Xuan Loc with the 23rd Artillery Group in the 2 / 35th Artillery. A second M108 battalion, the 1 / 40th Artillery, was stationed in Dong Ha in October 1966.).
The M108 was decommissioned when it was sold to NATO allies such as Belgium (18 units), Brazil (72), Spain (48), Taiwan (117), where they were converted into T68 turrets and Turkey (26).
Another difference in the hull was the lack of ground spurs on the stern.

M109:
The first M109 was completed shortly after the M108 in October 1963 with a 155mm caliber (cannon 11126 A1). The first deployment took place in Vietnam in the Armored Cavalry Squadrons, which had 6 vehicles per company. In September 1966 there were 3 companies in the 11th Armored Cavary Squadron. 5 battalions with M109 and 2 battalions with M108 were stationed in Vietnam, which is 57 M109 and 36 M108. They were used in prepared positions where they could optimally use their 360 ° swiveling tower and were protected against the RPG of the Viet Cong. The US Marine Corps has used these vehicles in their 4 / 11th and 5/12 marine units. The M108 was withdrawn from Vietnam in mid-1970 and the M109 in late 1971.
Today the M109 is in use all over the world (USA, Belgium, Great Britain, Italy, Egypt, Korea, Israel, Taiwan, Iraq, Iran, etc.) and is still in production. More than 8000 vehicles were built, including 950 paladins.
The M109 received its baptism of fire in Vietnam, where its weaknesses were obvious: It should only be used in prepared terrain.
The first major military deployment took place in the Yom Kippur War, where the Israelis used it intensively after testing the M109 between 1967 and 1973. To compensate for the weak armor on the M109 while it was in motion, they were protected by Merkava tanks. Firepower was improved during this war, especially during Operation Galilee in 1982. In addition, new ammunition such as the RAP (Rocket Artillery Projectile) was introduced.

The M109 from 1962 was converted into the M109 A1 which was replaced by the M109 A2 in 1978 and the existing M109 A1 was converted into the M109 A3. The latest M109 model is the Paladin, which is used by the US forces in Iraq. In my opinion, the Paladin is the ultimate model of the M109.
Description:
The cannon is built into a rotating turret, which is placed at the rear end of the hull. The whole vehicle was made of aluminum dural. The driver sits in the front left in the tub and the engine is in the front right with a large rectangular fan. The Christie style chassis has 7 rollers per side with the drive wheels at the front and the tensioning and idler wheel at the rear.
The IR system of the first vehicles was improved with more powerful systems such as residual light amplifiers.
The tower is more or less rectangular with two hatches on the tower roof. The cannon has a caliber of 155mm and has been continuously improved. It now rises above the chassis by 1/3 and has a huge muzzle brake. A smoke extractor is located in the middle of the pipe. The tower also has two side doors. There is a battery on each front of the tower and a large optic on the tower.
