Reducing or eliminating the duration of the Stealth Bomber's flight animation is an unrelated issue. And allowing SBs to be based on carriers simply to reduce their flight time is ridiculous.
If you hate long aircraft animations so much, then TURN OFF THE UNIT ANIMATIONS! Problem solved.
I don't pretend to
know what the Chinese aircraft designers are thinking -- but I do have access to magical wellsprings of information called "Google" and "Wikipedia". From them I
divined a picture and the name of the Chinese stealth jet, as well as experts' best estimates of its characteristics and capabilities. They're as follows:
The prototype Chinese Stealth Jet is called the
J-20 (Jian-20, which literally means "Annihilator-20").
Crew: 1
Length: 70 ft (21.26 m)
Wingspan: 42 ft (12.88 m)
Height: 14.6 ft (4.45 m)
Max takeoff weight: 66,00080,000 lb
The experts compare its design to the F-22 Raptor, which is characterized as an air superiority fighter, with additional capabilities, such as ground attack. So the Chinese stealth jet isn't even a dedicated bomber, which means that the B-2 Spirit is still the only "stealth bomber" in the world, and will remain so for the foreseeable future.
You mentioned that not all "stealth bombers" have to be as huge as the B-2. Perhaps, but there are
not any "stealth" aircraft -- fighters
or bombers, past, present, or near future -- that can be based on carriers.
The J-20's wingspan is ~45 ft like the F-22, F-117, F/A-18, F-14, but neither the F-22 Raptor nor the F-117 Nighthawk's wings fold or sweep, which is why they can't fit on the elevators and therefore inside the hangars of American super-carriers, which is why they aren't carrier-based. The J-20 is also 10 feet
longer than the F-22, F/A-18 Super Hornet, and F-14 Tomcat.
Admittedly, it's too early to know if the J-20 will have folding wings or if the new Chinese aircraft carriers can accomodate larger aircraft.
Regardless, all of the units in Civ5 are based on and modelled after historical or real world sources (the obvious exception being the "Giant Death Robot"). The Civ5 Stealth Bomber is obviously based on the B-2 Spirit stealth bomber, which is why it's not allowed to be based on aircraft carriers. This is both realistic, and fair for game balance.
