About Anaconda VS Corvette in turns of maneuverability

[GraXXoR]

The first picture is really bad when it comes to size ratio. The USS Ronald Reagan is 330 meters long. Anaconda is 150m long (according to ED wiki).
The second picture is also strange, but in opposite way. Football (soccer) field is approx. 100m long.

Yes, the carrier picture has been debunked for lack of scale a few times but it keeps popping up.

What I want to know is:

Sidewinder 9MW power supply
Corvette: 36MW power supply...

Hmmmokay then.
