Of course that there is, otherwise in description of ships you didn't read info about it

For example in description of Small cargo there is:

Rapidfire against Espionage Probe: 5
Rapidfire against Solar Satellite: 5
Rapidfire from Deathstar: 250

Yes there is rapid fire, but be carefull cause there's a few modifications between this retro version and the new universes.

Here heavy figthers do not have rapid fire against small cargos, cruisers only have 3 rapid fire against ligth figthers (unlike 10 in the new universes)
