The Scranton plant can make about 300 shells a day. The Ukranians are shooting 4000 rounds a day. The math seems a bit off to me. Basically, the entire world’s backstock of artillery ammo will be used up soon, as both sides draw down global reserves.
Nobody actually makes the forging presses, rotary heat treating ovens, or forges that are in that plant. They would be custom order, probably from either Anyang in China or SMS in Germany, with several year lead times. Increasing the capiacity by tenfold, enough to supply the small regional war in Ukraine, would be a huge project. Increasing production enough to match current russia consumption rates would be on the scale of building a tesla gigafactory, only Wall Street wouldnt pay for it.
There is something wrong with those numbers. From this document:

technology to manage the facilities during active and layaway periods (Williams 1978:xii-xiii).
During the late 1970s, experts focused on ways to protect the plants’ technological and computer
systems during layaway and ways to shorten reactivation time for these systems (Williams 1978:12).
5.6.3 Need for New Facilities
The majority of the plants in the Cold War ammunition production base were constructed
just before or during World War II. Of 27 facilities extant in 1982 – 16 active and 11 inactive – only
two first began producing ammunition during the Korean conflict. Riverbank AAP originally was
built during World War I as an aluminum plant, but did not start producing ammunition until 1952.
Scranton AAP was established in 1952 from the remodeled Delaware, Lackawanna, & Western
Railroad shops, and produced shell metal parts (Department of the Army 1982:49-58).
By the 1980s, the Army identified age-related problems with the ammunition production
base. Eighty-seven percent of the base was more than 20 years old, with obsolete equipment that
received minimal maintenance and funding during periods when facilities were placed on standby
status (Department of the Army 1982:21). Plans for future construction included single- and multi-
base propellant plants (Williams 1978:xii).
In 1982, Mississippi AAP, the first ammunition plant built in more than 25 years, began
production. The facility was built in Bay St. Louis, on the northern portion of the NASA National
Space Technology Laboratories facility, and operated by Mason-Chamberlain, Inc. The facility’s
mission was “integrated production” of the M483A1 155-mm ICM projectile, consisting of
manufacture of the projectile metal part; the cargo metal parts; and loading, assembling, and packing
the finished ammunition. This was the first time that a single plant handled all aspects of finishing
ammunition rounds. Historically, the metal components were manufactured elsewhere and shipped
to the load, assemble, and pack installation. Concentrating all facets of large caliber ammunition
production at a single location reduced costs (primarily shipping) and increased efficiency. The
plant was divided into discrete areas to serve the three aspects of the mission. The plant incorporated
the most sophisticated methods and manufacturing technology of its day and was designed to
produce 120,000 rounds per month (Department of the Army 1982:49).
That was 1982 equipment and technology and it was a more complicated product, a cluster bomb munition.
