Tech Slosh:
A hand'wavium term used to describe the condition existant in the SFU that prevents the Federation from capturing a Romulan ship and reverse engineering the cloaking device.
The big thing to remember is that the Star Fleet Universe has been around for 30+ years (since 1979) nad in that time, it has remained internally consistent. Severla things have been added (new empires, new ship classes, new weapons, etc.); but nothing has changed the intial view SVC had of the Star Fleet Universe.
Part of that original design was the idea that some wepaons would be useable by only a limited number of empires, and he has stuck to his guns for the whole 30+ years. Sure, you ould let every empire have cloaks, and photons, and ESGs, Oh My! But then, there would be no difference between the Federation and the ISC when it came to combat strategies and how the game worked. It would basically become 4th edition 40K in starships, with every empire having virtually identical stats.
Instead, every empire has it's own flavor... and that in itself explains why there are no Federation cloaks. They simply do not work with the Starfleet combat doctrine. No more so that a plasma torpedo armed Hydran ship would work with their preferred miltary strategies.
If you're curious, you can find a complete timeline of the SFU
here. Scroll down to Y158 for the Treaty of Smarba. This was teh treaty that sent several mothballed Klingon ships to the Romulans. From these, the Romulans were able to reverse engineer advanced warp tech and eventually build the third generation ships, the 'Hawks.
And there are some examples of tech slosh throughout the SFU. The Hydrans gave several Gatling Phasers to the LDR to keep them from joining with the Lyrans during the General War. The Romulans provided their Klingon allies with Mauler technology, the Federation provided the Tholians with some Photon Torpedoes during the General War, and even the Federation fielded several Plasma Torpedo armed ships along thier eastern border. These fought with the Gorn, so the similar weapons led o similar tactics.
All of this brings us back to the Orions. Jean was correct. The Orion Pirates are loosely based in various cartels. A map showig the areas occupied by the various cartels is
here. Typically speaking, the pirates do tend to use the weapons and systems of the empires in whose areas they operate as they are easily to, ehem... obtain. Not that that is a hard and fast rule however; and you can find examples of photon armed Orions operating in Hydran space and Hellbore armed ships operating in Romulan space. And if a Crime Lord has the capital to purchase a cloaking device, he will... and it doesn't matter which cartel he's a member of.
The Star Fleet Battles game and the Federation Commander game have detailed rules that are used to determine what optional weapons you OP ships have. The various wepons are limited in either number, cost, or both. But then again, those games are a bit more detailed than ACTA. And back to the original point of this long missive:
Cloaking Devices. In both the FC game and the SFB game, only Romulans have cloaks on all their ships and the Orions can field cloaking devices on a limited number and the point value is increased by 20%.
Now, if you want to allow cloaking devices on your Klingon ships - the SFU police are not going to break down your door and tell you to surrender your rule books and miniatures. But here are two caveats:
1) The Klingon ships are not pointed to include cloaks. If you add the cloak trait, you should probably bump the point cost. How much? I don't know, but hte 20% value would probably be a good starting point.
2) It's not canon. Much like SFB and FC, what you do in your own play seesions is up to you. But if you're ever playign ACTA: SF at a 'sanctioned' event, you will have to use the sanctioned rules.
