I would suggest a nuke if you really want to defeat armor in a way not based on kinetic energy. If you look at the pricing, nukes are pretty cheap.

Bombs as written already use missile warheads which have (admittedly completely worthless due to hardening mechanics) anti-armor features.

Spaceships bombs are kinetic weapons. Bunker buster bombs are also kinetic weapons, as far as penetration is concerned. k-kills are the answer. If your launch platform isn't capable of setting up a sufficiently high-speed attack run, the obvious fix is to get more speed by using a missile instead of an un-propelled bomb.
