I guess Crystal B, but that ship is so op I wouldn't count it. Plus I haven't unlocked it anyways.
I have all ships but Crystal and Mantis. ( I always either find mantis homeworlds on sector 7 or miss them completely ).
I've gotten the stasis pod reactivated before but I couldn't find rock homeworlds.
Well Crystal B isn't all that it's cracked up to be, RNG can mess you up big time due to your lack of offensive stuff such as weapons or drones. (and personally it's my least favourite ship in game)
For a Speed run to unlock ships it depends if your trying to unlock a ship.
For Mantis I sugest a ship you feel comfortable boarding in (or wasting scrap), you need level 1 teleporter and level 2 med bay I think to do the quest for mantis ship.
For crystal you may need rock ship due to it's augment.
If your doing it just for a challenge or youtube video then I suggest what ever you feel the most effective and fastest in, if that means Federation A, go for it. I know a guy who killed the final boss in a federation a on normal in like 15 seconds.
Teleporting and speed don't really go hand in hand. If you want to get through the game as quickly as possible I'd say go for either Osprey, Kestrel, or Red Tail. The Red Tail can shred most enemies in the first 2 sectors and assuming you can find better weapons you can carry that to the end, just laser spamming everybody. The Osprey and Kestrel start with the best weapon in the game (Burst Laser 2) and if you can find a 2nd one you're ready to face the boss. Of course, if you find a couple lesser weapons you're still pretty well set.
The Carnelian is a great ship, but teleporting over slow-moving guys to lock people out of rooms on the enemy ships is anything but a quick way to victory.

I'd say you can't beat a DA-SR12 with a free Weapon Pre-Igniter at the second jump point. Of course it's higly improbable but with the Long Range Scanners you're set for a good and quick run.
Achievement Loss of Cabin Pressure is currently bugged!
Well, you could look at what speed runs people post videos of.
Looks like many of the Easy speedrunners use the Crystal-B. Beeline to the exit on each level, if forced to engage, use the boarders to either kill everyone, or build them up while the engines charge (the stealth helps here too). By the time you get to the flagship, you should have picked up enough through events and the rest that you can field a team of four boarders. Kill (almost) everyone on the flagship on round 1, then drop the shields. Repeat for two rounds. Collect your prize.
I don't know what the best for a normal speed run is. I remember seeing someone doing it in a Red Tail (Kestrel-B) in under 25 minutes.
The Crystal B is definitely going to be your only good choice for a semi-reliable and consistent speedrun. The top 3 speedrun times all use the Crystal B (My 19:00, Panda's 20:13, and Jovalias' 20:45). Other ships could theoretically get some comparable speed but I feel they'd need *significantly* more luck to get there - personally I'd like to be able to make an attempt once every 20 resets instead of once every 200.
Like seeing other people getting into speedrunning this =) It's not the best speedrun game, but still a lot of fun! My 19:00 time is definitely improvable with better play and/or better luck.
