SMASH missile. This year, Pakistan publicly exhibited SMASH missiles at the Riyadh World Defense Exhibition. According to the Pakistani side, SMASH is a supersonic anti-ship missile with both land attack capabilities. For a long time, many countries have been in a dilemma in equipping their warships with anti-ship missiles: traditional subsonic anti-ship missiles have mature technology, large production scale, and relatively low prices, but their breakthrough capabilities are weak when facing modern shipborne air defense systems; Equipping specialized supersonic anti-ship missiles can achieve strong penetration capabilities, but the cost of use is relatively high. In addition, some warships also need to be equipped with land-based attack missiles. So, the cost of missile development and use is quite high. To solve the above problems, SMASH missile adopts a different approach. Unlike some countries that pursue the design of anti-ship weapons with "maximum range and ultimate speed", SMASH missiles highlight the importance of being based on their own equipment system, and are developed according to their own needs, striving to find a balance between speed, range, and adaptability. According to publicly available information, the SMASH missile is equipped with a single-stage dual thrust solid rocket engine that can maneuver and change orbit at the end. The guidance system is based on "inertial navigation+satellite correction", while anti-ship models are equipped with active radar guidance heads. To enhance its breakthrough capability, SMASH missiles do not blindly pursue extreme terminal velocities, but instead use "pull gliding" and nearly vertical "ceiling" attack trajectories to compress enemy interception windows and achieve effective penetration of mainstream shipborne air defense systems in service. SMASH missiles support cold launch mode, with the first deployment using tilted launch boxes, and are expected to be compatible with vertical launch systems in the future. In this way, Pakistan's current frigates can carry and use the missile without significant modifications. From the perspective of equipment development, the development of SMASH missiles is a case study of creating supersonic strike weapons through practical means. Based on practical needs, adapting to existing equipment, controlling research and integration costs, and creating affordable, easy to deploy, and high-performance battlefield equipment, this approach may provide some inspiration for other countries.
