5★ Battleship Shield Piercing is an endgame Combat research for Grade 5 and higher battleships. It raises their base Shield Penetration against explorers from 80% at level 1 to 350% at level 10, and it sits behind two Gebäude at once: R&D Department 53 and Foundry 51. If your PvP hunter is a G5 battleship, this line is where its explorer kills come from.
What 5★ Battleship Shield Piercing does
Shield Penetration decides how much of your damage ignores the target’s shields and lands on hull. This project raises the base Shield Penetration of Grade 5+ Schlachtschiffe when firing on explorers, sharpening the edge battleships already hold over explorers in the combat triangle. It applies to player and hostile explorer targets alike; it does nothing for your interceptors, explorers, or lower-grade battleships.

Unlock requirements
Every level needs both an R&D Department and a Foundry level, plus progress in the 5★ battleship weapons line, starting from 5★ Battleship Weaponry 1. The full ladder is in the table above.
Cost and research time
Per-level costs are in the table above. Maxing all 10 levels totals about 603.2B Tritanium, 2.2T Dilithium, 205K 5★ Common Refined Ore, 46K 5★ Uncommon Refined Ore, 45.1K 5★ Rare Refined Ore. The base research time adds up to roughly 58.6 yr on paper; research speed bonuses cut real timers to a small fraction of that, so use it to compare levels, not to plan your calendar.
Is 5★ Battleship Shield Piercing worth it?
For PvP players flying G5+ battleships, yes: 350% shield piercing changes how fast an explorer dies. If you rarely PvP or fly other hulls, park it until the buildings are leveled anyway. The whole branch is on the Combat Research guide.
