The invention discloses an acceleration/pressure measuring device for a projectile launching water entry test. The acceleration/pressure measuring device is structurally composed of an acceleration measuring unit, a pressure measuring unit and a controller unit. Wherein the acceleration measuring unit and the pressure measuring unit are respectively connected with the controller unit through waterproof wires; the circuit is composed of five parts: an acceleration measuring circuit, a pressure measuring circuit, a lithium battery power supply circuit, a FLASH memory circuit and a microprocessorcontrol circuit. Wherein the microprocessor control circuit is used for controlling the whole device to work, and is electrically connected with the acceleration measuring circuit, the pressure measuring circuit, the lithium battery power supply circuit and the FLASH memory circuit. The utility model provides a device capable of automatically measuring acceleration and pressure when a projectilebody impacts a water surfa
