Junker Salvage Frigate weapons question.

[good_old_alf]

The salvage frigate is a transport with access to gunboat weapons - a hybrid ship essentially, it can mount standard transport turrets as well, but it cannot mount the heavy transport weapons, nor am I able to buy the new gunboat missiles anywhere (insufficient rep) to even see if these would be mountable.

Would it be possible to enable it to mount the transport heavy turrets, or the new (silencer and harpoon) missiles? Either one would be good, just to add a bit more variety. Or is this current situation how it was meant to be - for balance reasons?

Apologies if I'm being a bit old and crap, and have missed the relevant info somewhere.
