Traditionally, a missile interceptor's three-loop autopilot relies on every sensor to be working at all times for an intercept to occur. With faulty sensors and countermeasures becoming more sophisticated, sensor improvements alone may not be enough. In this research, an alternative structure is presented that does not rely on multiple sensors. Instead, it consists of a single-loop using only the relative normal velocity as feedback in an integrated guidance and control (IGC) structure. This establishes a direct link between the feedback and the missile's control surfaces. At its core, the IGC uses higher-order sliding mode control techniques to execute the intercept strategy. Three different higher-order integrated guidance and control algorithms are presented and compared through simulations to a traditional (G\\&C) system. Two of these are designed with only the knowledge of the input-output relative degree of the missile and the target's acceleration bounds. The third is an adaptive control strategy that only requires the input-output relative degree and instead adapts by estimating a lumped disturbance on the system. Each of these control algorithms were judged on performance and output signal smoothness as a means for determining their practicality in a real missile interceptor.
