Allow me to shed some light on the situation.

First off, the Pantheon puts quite alot into the creation of it's fleet, since it's their primary means of expansion. Most Pantheon ships are partly bio-mechanical, so small craft (frigates, escorts. etc.) are easy to mass produce, while larger craft (battleships, crusiers) are much harder to create. Like the Imperium, the Pantheon really hates to loose ships.

However, since the planet in question would be recently conquered, a small blockade would be in place in order to prevent people from escaping offworld. This would hardly be a massive fleet, but stil sizable enough to be a formidable opponent during a Void Battle. In addition, the Pantheon will probably have anti-aircraft weapons set up on the planet.
