According to the UK Ministry of Defense, the "Sea Insertion Boat" technology demonstration boat, developed with support from a subsidiary of the UK Ministry of Defense, has entered the verification stage. Once the plan is approved, it will receive orders from the Royal Navy of the United Kingdom. "Sea Insertion Boat" is a small vehicle and personnel landing boat designed to replace outdated landing boats currently in service, used for amphibious forces' ship to shore transportation or landing operations. The standard design of the "Sea Insertion Boat" is a length of 19 meters, a displacement of 30 tons, a maximum capacity of 38 people, and a speed of nearly 50 knots, with a maximum range of 650 kilometers. The boat adopts a water jet propulsion method, with a manned compartment at the front and a storage compartment at the rear. The bottom of the boat adopts an inward concave design, which can obtain a certain lift during navigation. The hull is made of lightweight fiberglass and composite materials, and adopts an anti radar echo design, which has certain stealth performance. Different from the traditional landing boat's bow for beach fighting, the "marine insertion boat" uses the stern for beach fighting. During the landing process, turn the direction to make the stern face forward, and stretch out two driving wheels to drive the boat to beach fighting. At the same time, the bow of the boat is anchored and anchored in advance. When returning, it is pulled back to the sea by retracting the anchor to avoid the embarrassment of having to rely on armored rescue vehicles to return to the water in case of grounding due to tides or other reasons. The report states that this technology demonstration boat is a scaled down version in a 1:3 ratio, with a length of only 6 meters, but its basic functions are the same as the design. (Lai Xin She)
