I can't find it now, but Schuler's largest stock press could not accommodate 800mm+ stroke
That's why, for example, an automobile crankshaft forging press could not be adapted - crankshafts are forged flat
So this ends up being a custom job, which is part of the delay. (and an obvious argument that you mothball these things in peacetime, not sell them for scrap)
Every one of these machines is made custom. So you CAN order them up, and pay extra for the privilege. I am certain there will be several outfits (and not just Chinese ones) who would be happy to quote you for the job.
The problem, from the beginning, has been an unwillingness to shell out (ha) for the required investment. Such as, for instance, the Germans reluctance to place long term military contracts. The German governments (both of them, so far) have been particularly stupid.

The 155 mm shell, a critical munition used in artillery systems, plays a pivotal role in conflicts like the ongoing war in Ukraine. Let’s delve into its composition:
Material and Forging:
The steel bodies of these shells are forged at specialized facilities, including the Scranton Army Ammunition Plant in Pennsylvania, USA.
Tons of steel rods are brought in by train to be shaped into these artillery shells.
The 155 mm shell is a two-piece round, consisting of a projectile and a propellant charge12.
The steel bodies are crucial for the structural integrity and performance of the shell.
Purpose and Use:
Originally designed as a chemical artillery round, the M110 155 mm projectile was intended to deliver blister agents via howitzers.
It replaced the World War I-era 75 mm chemical projectiles.
These rounds are used in howitzer systems, allowing forces to engage targets up to 20 miles (32 kilometers) away with highly explosive munitions3.
Supply Challenges:
The invasion of Ukraine exposed a critical issue: the U.S. stockpile of 155 mm shells (as well as those of European allies) was unprepared for a major conventional land war.
The dwindling supply alarmed military planners, prompting efforts to bolster production.
The Scranton plant is one of just two sites in the U.S. that manufacture the steel bodies for these shells.
The U.S. has provided over $35 billion in weapons and equipment to Ukraine, with the 155 mm shell being one of the most requested items14.
In summary, the 155 mm shell’s steel composition and precise forging are essential for its effectiveness in combat scenarios. Its production and supply remain critical for supporting allies and maintaining readiness in an ever-changing geopolitical landscape.
