How to trivially defeat anti-shield weapon equipped fleets

[Phoenix-D]

"In order to lift off from a planet, you need to have enough force (Escape velocity) to overcome inertia. Heavier the ship, the faster the escape velocity."

Not quite. Escape velocity is the *same* for any and all objects. It's the force required to get there that differs. 600kt of ship would take quite a lot of thrust to get up.. but nothing says that thrust has to be delivered like it is now (i.e. really fast HARD rocket kick).

Put it this way. In a car, you can floor it, and reach 60mph quickly. Or you can accelerate gently and reach 60mph slowly. The percieved force is quite less the second way, but the speed is the same! The hard part is finding that point. 1.001G of thrust on an earth-mass planet would do it. The only reason we can't do something like that now is we'd run out of fuel before we hit orbit.
