The LAU-7/A guided missile launcher provides a complete launching system for which of the following guided missiles?

The LAU-7/A guided missile launcher is specifically designed to support the AIM-9 Sidewinder missile, which is an air-to-air infrared-guided missile. The design and functionality of the LAU-7/A make it suitable for launching this type of missile, providing the necessary mechanical and electronic systems to ensure proper deployment and guidance during flight.

In contrast, the other missiles mentioned in the options are not compatible with the LAU-7/A launcher. The Tomahawk is a long-range, all-weather, subsonic cruise missile primarily launched from surface ships and submarines. The Harpoon is an anti-ship missile that requires a different launch platform typically found on ships or aircraft equipped for its deployment. The Stinger is a man-portable air defense system that is not designed for use with the LAU-7/A launcher.

Thus, the LAU-7/A's specifications and intended use directly align with the Sidewinder, making it the correct answer.
