【FV433自行火砲】英國最小自行榴彈炮，短小精悍性能超越大多數同時期火砲，印度卻只對閹割版情有獨鐘，如今大多流入民間

FV433自行火砲空重約16.5噸，車長5.8米（炮向前 ），寬2.6米，高2.5米，最大行駛速度47千米每小時，最大行程480千米。
自行火砲內部彈藥架可以攜帶42發分裝彈藥，它們分佈在砲塔內部四周以及車體內，火砲採用37倍徑身管，砲塔旋轉為電動，火砲俯仰則為手動。彈藥的主要型號有HE、HESH、煙霧彈、照明彈。發射藥被放在黃銅彈殼中使用，射手可以根據射擊需要選擇裝填多少包發射藥，以及選擇常規彈殼還是加壓彈殼，在使用強裝藥時最大射程可以達到17.3千米。 FV433緊急情況下可以直瞄射擊，不過因為車輛太緊湊沒有相關的光學設備，因此砲塔頂部的自衛機槍擔任起了矯正的功能，早期安裝的是一挺布倫機槍升級版型號，後來被其它的7.62毫米機槍替換。 FV433的裝甲防護偏弱，車體的正面和側面裝甲厚12毫米，尾部厚10毫米，底部厚6毫米，砲塔正面和頂部厚12毫米，側面厚10毫米，只能抵擋輕武器和砲彈破片的傷害，車上有三防裝置。車輛內部空間有限，很多工具箱等外掛在車體、砲塔外部，起到一點額外的保護。
The FV433 self-propelled artillery has an empty weight of about 16.5 tons, a vehicle length of 5.8 meters (the gun is forward), a width of 2.6 meters, a height of 2.5 meters, a maximum speed of 47 kilometers per hour, and a maximum travel of 480 kilometers.
The internal ammunition rack of the self-propelled artillery can carry 42 rounds of sub-loaded ammunition, which are distributed around the interior of the turret and inside the car body. The main types of ammunition are HE, HESH, smoke bombs, and flares. The propellant is placed in a brass shell, and the shooter can choose how many packets of propellant to load according to the shooting needs, as well as choose a conventional shell or a pressurized shell, and the maximum range can reach 17.3 kilometers when using a strong charge. The FV433 can shoot directly in an emergency, but because the vehicle is too compact and has no relevant optical equipment, the self-defense machine gun on the top of the turret acts as a correction function. An upgraded version of the Bren machine gun was installed in the early stage, which was later used by other 7.62mm machine gun replacement. The armor protection of FV433 is weak. The front and side armor of the hull is 12 mm thick, the tail is 10 mm thick, the bottom is 6 mm thick, the front and top of the turret is 12 mm thick, and the sides are 10 mm thick, which can only withstand the damage of small weapons and shell fragments. , There are three defense devices on the car. The interior space of the vehicle is limited, and many toolboxes are attached to the outside of the vehicle body and turret to provide a little extra protection.
