Budget estimate

$10,000,000 – $50,000,000

Given the nature of the project, which involves the development and potential production of medium caliber ammunition, the budget is likely to be substantial. However, without specific details on the budget or funding available, it's challenging to provide an exact estimate. Considering the 36-month period of performance and the potential for follow-on production, a reasonable estimate for the budget could be in the range of $10 million to $50 million. This estimate is based on the assumption that the project will require significant resources, including research and development, testing, and production, and that the U.S. Army will be investing heavily in the development of this ammunition.
