Do CBU bomblets have a propulsion system and guidance section for controlled flight?

CBU bomblets, which are submunitions found in cluster bombs, typically do not have a propulsion system or guidance section for controlled flight. They are designed to disperse over a wide area upon release from an aircraft and rely on gravity for descent rather than powered flight. Some modern submunitions may incorporate limited guidance features, but traditional CBU bomblets primarily function as unguided, explosive payloads.
