Analyst Note:
The circles in this image indicate where the fixed fin assembly is connected to the bomb body. Fin assemblies such as this help stabilise the bomb as it falls, improving the predictability of the trajectory and thus precision. Fins also orient the bomb as it falls so that munition travels nose-down. Orientation of the bomb on impact can play a role in fuze functioning, as well as the distribution of explosive or other effects. (ARES)
