Artillery: Smaller, Lighter, Cheaper, Faster
October 14, 2021: In early 2021 a Chinese firm revealed a new supersonic cruise missile called HD-1. It uses a novel solid-fuel ram jet to achieve speeds of 750 to 1,200 meters a second to hit targets up to 300 kilometers distant. This propulsion system is lighter and more compact than existing ramjet systems. HD-1 can be programmed to fly as high as 15,000 meters (48,000 feet) or as low as ten meters (30 feet) for use against surface ships. The one-ton HD-1 is 8.3-meterss (27 feet) long, 375mm in diameter and can carry a warhead weighing 240 kg (530 pounds) to 400 kg (800 pounds). The heavier warhead reduces range and speed and would be used for ground targets. The standard HD-1 is described as a carrier-killer although it would require several HD-1 to disable or destroy a large carrier. One HD-1 could disable a smaller warship like corvettes, frigates or destroyers. Multiple HD-1s can be carried by a TEL (Transporter Erector launcher) vehicle or launched from aircraft or ships. HD-1 is also half the price of its main rival, the Indo-Russian BrahMos. The HD-1 is being offered to whoever can pay for it, while BrahMos sales are restricted to nations considered friendly by India.
