I love the 6. 1 update, especially the more flexible engine design. In fact, it inspired me to design a fighter-weight shuttle craft to cart my geology and xenoarchaeology teams around. I put a 50% power size-1 ion engine and an efficiency 5 size-1 military jump drive on an otherwise empty fighter, then I just filled up the rest of the space with enough engineering spaces and crew quarters to give it a deployment time measured in decades. By the time I face morale and maintenance failures it'll be time to replace the ship outright.
All was going well; my geo team just finished a tour of the Jovian moons and had just started in on Saturn when my survey ship discovered a Destroyed Outpost on Alpha Centauri A-I. I cranked out another shuttle, loaded up my xenoarchaeologists and sent them to investigate, only to run into a problem.
When I attempt a standard transit I receive the error:
"ST Beagle 002 cannot carry out its standard transit order as at least one ship is larger than the ship with the highest jump rating. No friendly or allied jump ships are available for escort"
This is weird, because the Beagle's jump engine is rated for 250 tons, and the ship itself only weighs 243 tons. When I try a squadron transit I receive the error:
"ST Beagle 002 cannot carry out its squadron transit order as either at least one ship is larger than the ship with the highest jump rating. "
The error message itself seems to imply a missing second explanation, but the real problem is I can't get the silly thing to jump.
On a hunch I SM'ed in a Beagle Mk. II with a size-1 box launcher and a size-0. 1 fire control. I had to sacrifice a bit of endurance to fit both in, but the resulting shuttle was 250 tons on the nose. This ship could standard transit and squadron transit just fine, and its marginally larger size indicates that size is not the problem at all, despite the error message.
I also created a larger, non-fighter version. The 3500-ton shuttle uses a larger number of the same fighter engines and a larger but still self-only jump drive. It traversed the jump point without a hitch, standard and squadron.
The problem seems to be that a fighter whose only non-commercial component is its engine will not jump to another system under its own power. I'd appreciate it if someone would check this before I go throwing it into the main bug thread, just in case the problem is actually user error. Below are my three ship designs:

there are two condition for squad jump or escorting : Jump Engine higher or equal than the biggest ship AND the jump ship itself is bigger than the rest. In your case it's 243 vs 250 - can't jump

But the Beagle has a jump drive. That puts the capacity at 243 tons. It should be able to solo transit.
-
It definately sounds like a bug, as you should be able to self transit. Have you tried making a version with just the jump drive, engine and absolutely minimal fuel/engineering space that would be smaller still and seeing if that can jump?
-
I didn't think that ship size was the problem, since the Mk. II uses the exact same jump drive as the original and it's 7 tons bigger. To be thorough I tried it out. I designed a stripped down Mk. III:

It won't jump either. Same error messages. Unless someone else can point to an error in the design, I'll throw this into the bugs thread later today.
-
My guess is that since it is classed as a fighter, that's why it cannot jump. Prior to 6.x, fighters had to be on a carrier to transit. It's possible there is code prohibiting a fighter from jumping.
When you put the bug in, reference this thread. :)
-
I could have sworn that in Steve's NATO campaign he would send fighters alone through jump points a few times for scouting purposes. That was using the jump drive onboard the carrier mind you, but that might be the trick as opposed to nonjumping fighters entirely.
-
I learned something today.
In my old 5. 6 game I had a 250ish ton jump scout that I would park in the boat bay of my scout frigate when I would send it on first-in missions. The idea was that the jump scout would traverse the jump point first, and if it ran into something dangerous, like a powerful black hole, I wasn't putting the frigate at risk. I could never get it to squadron transit, but it could standard transit just fine. I thought it was a limitation of self-only jump drives, but upon digging out the old save I discovered that it wasn't jumping under its own power. The frigate was apparently escorting it. Move the mothership off the jump point and it fails just as the Beagle did.
Back to the present, the Beagle is an evolution of this previous design, so I tried out an updated version of my old jump scout:

It won't jump either, squadron or standard. This undermines my hypothesis that the non-commercial box launcher and MFC on the Beagle Mk. II tripped some conditional statement in the jump drive code that the Beagle's engine alone was failing to trigger. Either the Saluki's non-commercial 2. 25 HS active search sensor also suffers from the same fault as the Beagle's engine, or there is something unique about either the missile launcher or the fire control which enables the jump drive to work.
Now I'm curious. What about jump gauss fighters?

Nope. Neither squadron nor standard. Note that this larger fighter required a new, larger jump drive.

Still nothing. No squadron transit. No standard transit. Just to confirm my own sanity, I double checked that the Beagle Mk. II can jump. Yes, it still can, both standard and squadron. This is especially weird because both the Mutt and the Mutt Mk. II were designed by copying the Beagle Mk. II and subtracting one part or the other.
Gestalt ship design. My mind is officially blown. :o
EDIT: Charlie Beeler appears to have solved this mystery a mere five minutes after I posted it into the bugs thread. The problem is that the fighter's weight must match the jump drive rating exactly. Here is the latest model of the Beagle:

It jumps just fine. As he stated, this need for precision does remain a bug.
Way to go, Charlie. Now I can send my intrepid crew of scientists and their lantern jawed captain out into the farthest reaches of known space to hunt for antediluvian ruins and green skinned alien women who dance the Dance of Seven Veils.

The thing is that it is still a bug as it shouldn't need for the fighter to be exactly the same size as the jump rating, it should also work for a fighter that is smaller than it's own jumpdrive rating.
-
My guess is that since it is classed as a fighter, that's why it cannot jump. Prior to 6.x, fighters had to be on a carrier to transit. It's possible there is code prohibiting a fighter from jumping.
When you put the bug in, reference this thread. :)
No, that's not the reason. There is no restriction on fighters jumping. No clue what the problem is at the moment though :)

Yes, that does sound like a bug - a ship shouldn't need to be the exact same size as the jump drive rating. I'll check the code
EDIT: just created a 4000 ton ship with a 6000 ton jump drive and it jumped with no problem.

It seems to be happening only to fighters, and only when they are not at integer multiples of 50 tons. Perhaps it is something in the code that causes the fighters to use the exact class size for their size instead of rounding up to 50 ton intervals, interacting poorly with the code used to check for the ship being small enough to jump?
-
Actually that reminds me of an issue I've had with 15000 ton troop carriers equipped with jump engines capable of jumping 18000 tonnes. Never figured out why they couldn't do it. I'll add it to the bug thread.

Good catch. I chopped my design down to 150 tons and it worked fine, but 140 tons wouldn't jump at all.
Victuz, you're still having trouble with your troop transports in 6. 1? I just threw together a commercial ship, 16,600 tons with a 19,000 ton jump drive. I didn't have any problem getting it to jump.

Good catch. I was tracking the size of jump drive needed for the largest ship in the TG. However, that variable was a long and Hull Spaces is a fixed point variable. It was rounding to the nearest integer (so fighters of 120 tons would probably work but not fighters of 130 tons :))
So now when I check the largest jump drive, the jump drive required value is slightly higher than the most capable jump drive in the TG. This doesn't happen for ships as they are rounded to the closest HS. It will only affect fighter sizes that would round up to the next largest HS. Anyway - fixed for v6.20.
