Added descriptions below from FFE manual. Here's Jades' website shiplist if you want to browse:

I assumed they meant the Eagle Mk3 rather than the Mk2, as the tier's called Imperial Bounty Hunter and the Mk3 is the Imperial version of the Eagle. The Mk2 is also crap, so there's no way they'd give you that one with the FFE stats

. Perhaps expect the ED version of the Eagle to have a slightly larger hold, although the Sidewinder tier has basic equipment and 100 CR whereas the Eagle one is fully upgraded and has 1000 CR.

The most famous attack craft ever, the Sidewinder was once the only ship pirates were ever seen in. Deceptively small looking, due to its narrow frame and centre mounted laser cannon, this sleek little ship still keeps up with the latest technology, seemingly effortlessly — a tribute to the forward thinking designers, whose names are now lost in the mists of time. The lack of missile pylons was considered a mistake at the time, but the speed of the ship means that it can take out most craft long before a missile would ever reach them, and the reduced weight gives the craft superb handling and braking power. Somehow there is room in there for 25 tonnes of cargo space — again another tribute to the designers — so there are plenty of reasons to dictate why this ship is still as popular today as it ever was, even in the face of some stiff opposition.
Bob’s thoughts If killing is your business, then a ship like this will ensure that business is always good. Lethal from laser tip to engine, this is a cruel machine, that instils an almost heartless quality to your bounty hunting — which is probably why I sell so many of them. Everyone wants to be the bad guy every once in a while, right? You could use it for trading if you wanted, I suppose, but then you lose your powerful laser and your only attack mechanism is removed, which leaves you deader than leaves on the line, if you get what I’m saying.
Eagle Long Range Fighter Mk III

Capacity: 22t (drive + 12t)

It took the Empire’s better paid designers to fix the problems of the Eagle long Range Fighter Mark II — something they did in almost no time at all. In fact, there was a lot of talk at the time of imperial designers destroying the work of the Federation while they were building their upgrade, as the imperial blueprints fixed every major, and even most of the minor flaws behind the Mark II. The ship is still amazingly fast, pulling a huge 28 Earth G’s acceleration, but now has stronger retro power than ever before, reversing at speeds that most combat ships fail to reach from their main engines. The thing that caused the most suspicion was that the imperials had managed to do this while retaining the dimensions of the Mark II. A long and drawn out court case ensued, but collapsed after 15 years due to lack of funds on the Federation side, and the matter was laid to rest.
Bob’s thoughts Now this is class. Every so often, one of those boffins with the large foreheads and the spanner collections sets out to do something, and they get it right. You couldn’t ask for a better combat ship. It’s got all the speed you could ever need, it’s got more than enough in the weaponry department, and you can fly it solo. The seating can be a little uncomfortable, especially since they introduced these waterbeds as chairs. Forgive me for being an old stick in the mud, but I happen to like the kick you get from slamming in retros with this kind of power. If you’re into combat, then this is one serious piece of kit to get hold of. Uncle Edo’s got some of these too. Remember, Bob sent you.

Allegiance: Independent, Federation
After a complete rethink following the collapse of the Cobra Mk II, the Federation shipyard, Faulcon DeLacy addressed some of the problems facing pilots of their day and came up with what was to be their best ship ever — the Cobra Mk III. In the 20th Century, as any history buff will know, a motor car company by the name of Ford came up with a car called an Escort, which was generally regarded to be their finest hour. The Cobra Mk III can only be described as the Ford Escort of the space lanes. It has the classic lines that millions of ships tried to emulate. It is nippy, easily manoeuvred, powerful, attractive, spacious and well defended. The only craft that Faulcon DeLacy ever built that was deemed to be more classic was the now defunct Fer de Lance — a vicious piece of combat machinery that is now outlawed, as the Police deemed it too powerful to be left in the hands of the public. The Cobra Mk III is one of the most recognisable ship in space. Countless thousands were built, and new ones are still built by Faulcon DeLacy as well as under license by other shipyards. ship is extremely popular with traders and bounty hunters alike due to its versatility as a cargo carrier and a weapons platform. The Cobra Mk III was named ‘Ship of the Century’ in ‘What Spaceship?’ magazine in a recent poll, and with good reason.
Bob’s thoughts How can you go wrong with a Cobra Mk III? Okay, so there might be a lot faster ships out there, and there are ones that are larger, ones that have more weapons and ones that are easier to upgrade, but you sure as hell aren’t going to find one ship that has all of these things. The Cobra Mk III was the work of a genius, and there hasn’t been a ship yet that has sold so well. Sheesh, these things go so easy, I don’t have any left, so if you know of anyone who wants a good price for their’s, I’m happy to buy it off them for 60 percent of current value.
