The SC Cain was a Shivan class of cruiser. Cains were the mainstay cruisers used during the Great War and were still popular during the era of the Second Shivan Incursion.
The Cain had an advanced variant, the SC Lilith.

FS1 Tech Room Description
The Cain is by far the most common cruiser in the Shivan fleet. It is also the weakest. However, the Cain should not be underestimated. It has many turrets, as well as a cluster bomb defensive mechanism. As a strike cruiser, the Cain mostly appears in attacks against GTA or PVN capital ships and cruisers. In these cases, it should be destroyed immediately. The primary weakness of the Cain appears to be its unshielded turrets. Most of the turrets on the Cain can be destroyed with minimal damage.
The Cain is a Class B threat.
FS2 Tech Room Description
The weakest of the Shivan cruiser classes is designated SC Cain. These vessels were commonly encountered during Great War battles. Cains are considered to be slightly stronger than the GTC Fenris cruiser class.
| The SC Cain in FS2_Open 3.6.12
According to the Bible, Cain was the first son of Adam and Eve. Cain commits the very first murder, killing his brother Abel.
The Cain is considerably stronger than a Fenris, but has an even worse anti-fighter point defense: with only one AAA turret on the bottom rear of the ship and a couple of weak missile launchers, it leaves the top of the vessel virtually undefended. As far as anti-capital work goes in cruisers, the Cain is pretty good, with a single SRed it will most likely take some skin of the nose of whatever capital ship it attacks it before going down, which it will with only 20,000 hitpoints. A wing of Herc IIs or Myrmidons should have no trouble taking down the Cain, nor should a Deimos, and a wing of bombers will take this ship down very quickly, it takes five Cyclops torpedoes to take this beast down.
No need to bomb the Cain. Just use your primaries on the hull or turrets. Or sit behind it and shoot its backside off. About 2 minutes should do it if you're on your own, half to 1/3 with a Kayser or Maxim loadout.
Here's a little note for those who are interested: in retail, both the Cain and Lilith look exactly the same, having the same hull theme much akin to the SD Ravana (grey-red instead of black-red), but in versions of FS2_Open before 3.6.10, the Cain gets a new, black-themed hull while the Lilith retains the old Ravana-esque hull. In 3.6.10, the hull textures are swapped, so a Cain in 3.6.10 now looks like the retail Cain version again.
Be careful when performing a Trebuchet attack against its beam cannons that you select the correct cannon. From the front both its anti-fighter and main beam are lined up in your target view, and it's almost impossible to tell which one you are attacking, for sure. Fly a little bit below the cruiser, so you can tell which turret you're firing at. Also, double check you're attacking the beam from the correct side. If you attack from the top of the ship instead of the bottom, there may be some damage to the turret, but it won't go down.
