That is what I needed. Basically, the only reason I would use them would be a Massive mount on a large weapons platform. 5x damage and +7 range. So it looks like I am going to need to go through a couple more areas of the tech tree to get to the disrupters. The empire attacking me places 7 to 8 shield generators on his BB and DNs and it is a pain to try and weed through that, even with massive mounts. But hopefully the 45 large weapon platforms with massive quantum V torpedos and 1000 fighters on the next planet he is attacking will put a dent in his fleet.
Thanks for the info.
