<p>This study proposes an energy-optimal deployment strategy for carrier-type missiles tasked with engaging multiple targets. In contrast to conventional cooperative guidance frameworks that rely on independently launched missiles, the proposed architecture involves a carrier missile that transports and deploys multiple sub-missiles during flight. Each sub-missile inherits the carrier’s velocity and kinetic energy at the moment of deployment, making the release conditions critical to interception performance. To address this challenge, an optimal control problem is formulated to determine the carrier’s deployment position and angle that minimize the group-level control energy of the carrier and its sub-missiles. By adopting the Impact Angle Control Guidance law, closed-form solutions for trajectories and accelerations are derived, allowing the deployment optimization problem to be reformulated into a low-dimensional form without explicit dynamic constraints. This reformulation substantially reduces computational complexity, thereby enabling real-time implementation. Moreover, the proposed strategy alleviates acceleration demands, which simplifies sub-missile design and improves overall interception performance. Simulation results further demonstrate the effectiveness and practicality of the method in complex multi-target engagement scenarios.</p>
