The main purpose of this legislation is to ensure that civilian and military public shipyard workers continue to receive their pay during a government shutdown. It aims to provide financial stability for these workers in the event that the government fails to pass necessary funding measures. Key provisions of the legislation include the allocation of funds for the fiscal year 2026 to cover the salaries and allowances of public shipyard workers. This funding will be available during any period when there are no approved appropriations for that fiscal year.
