We learn a great deal about the
performance of the Falcon in this film, and of ISDs. The Falcon appears
to have somewhere around 30
g
of
high-maneuverability acceleration, which can be altered swiftly on
demand just as well as a starfighter. Linear acceleration seems similar.
ISDs have fully equal
linear
acceleration to the Falcon; however, they are incapable of coming to
full acceleration quickly, or turning quickly.
TIE fighters and bombers are at least somewhat faster than the Falcon,
although they do
not appear to have superior maneuverability.
The Falcon
appears capable of
fairly high maneuverability, being able to turn around at full throttle
in a roughly half-circle figure in roughly 3 seconds. If the circle is
a
bit over a half kilometer wide, this would place the Falcon's unaided
acceleration at ~30
g; if a
full
kilometer wide, ~56
g. This
occurs shortly before an approach in which the
Falcon spent 2-3 seconds swinging
to a halt after flying the length of a Star Destroyer in roughly nine
seconds.
The ISD cut forward speed as the Falcon approached. Taking 1600m for
the length of what bridge officers interpret as an attack run on the
bridge, this represents an average speed of roughly 180 m/s. If the
relative acceleration was constant during the attack run, the final
speed of approach could have been as high as 360 m/s relative to the
ISD. In this case, the relative acceleration between the two vessels is
40m/s
2 during the attack run, and up to 120-180m/s
2
(12.2-18.4
g) while braking -
in either case, not particularly high compared to the acceleration seen
in the Falcon's turnabout.
Either Han wasn't going full out, or the ISD has a high reverse
acceleration that was used in this run. In either case, the sum of the
two accelerations is also a reasonable estimate (160-220m/s
2),
assuming that the ISD is accelerating rearward at full Falcon-reverse.
The ISD
chasing the Falcon had no trouble keeping up with the freighter. Thus,
it is as fast. However, if ISDs were capable of applying 30
g on a couple seconds' notice, it
would be possible for an ISD to dodge an ion cannon bolt with the
flight times seen onscreen. We may
therefore suggest that an ISD may not change its acceleration
too
swiftly. Alternately, an ISD might
not have the command response time necessary to detect an ion or
turbolaser bolt as a threat and then dodge it.
A near-collision at the Imperial fleet's exit from hyperspace
demonstrates their turning abilities - poor at best.
The TIEs
sent after the Falcon had no trouble catching up with it, or
accelerating past the ISDs that launched them. Thus, they have greater
linear acceleration. However, their maneuverability does not seem
greatly improved from the Falcon.
