The targeted time period for Tier-1 solutions is minutes to hours from the time at which the need is established.
Tier-1 uses existing or on-station capabilities to provide highly responsive space effects through the employment/modification of existing, fielded space capabilities. The targeted time period for Tier-1 solutions is minutes to hours from the time at which the need is established. These solutions focus on existing ground and space systems, operations and processes. Although mission or system utilization analyses may be needed, Tier-1 solutions will not typically involve the design, engineering, or fabrication of new material items.
