Elite Dangerous: All playable ship shield comparison
Anaconda has strongest shields but Sidewinder - weakest. With shield boosters Anacondas shields can gain even 160% in strength because Anaconda has 8 utility mounts. Vulture and Fer-de-lance has power issues that's why their base shield is so strong - you will not be able to fit powerful weapons, best modules and use shield boosters at the same time.
