“The Army expects production of 155mm artillery shells will jump more than threefold next year from 24,000 per month to between 80,000 and 85,000 per month, said Douglas Bush, assistant secretary of the Army for acquisition, logistics and technology…
Some of the reasons it is taking so long to increase artillery shell production are that the Army is establishing entirely new production lines for the shells themselves while also increasing production of the triple-base propellants that launch the projectiles and increasing the capacity to load shells with explosives, Bush said.”
