Built-in armour for hulls

[Suicide Junkie]

Adding a hundred or so phased shields to the hull is not that big a deal. If the player adds normal shield generators, the PPBs will work normally, and skip all the shields.
If the player dosen't add normal shields, the ship will be protected from the first 1 or 2 PPB shots, but that dosen't make much difference in the outcome of the battle.
