Ship:raines
From NEBULOUS: Fleet Command Official Wiki
From the front, the Raines is functionally immune to 100mm HE, as the shells fuze in the middle of the bow and cannot reach the middle of the ship. Compartments 4 and 5, and Module 5 will die relatively quickly, and Mounts 3 and 4 will be killed over time by rounds hitting their respective parts of the hull instead of the bow. The only way 100mm HE can kill from the front is via structure break from shells specifically hitting near Mounts 3 and 4, something which can take over 700 rounds.
