[Transformers 2] Why didn't the US Navy blast the Sun Harvester with that new railgun?

It took out that massive NBE like it was nothing. It's pretty damn accurate if it can hit a 70-90 foot target from miles away.

Why the fuck didn't it shoot that damn machine!? And don't give me any bullcrap about running outta energy. My buddy was in one of the planes that tried to shoot that thing! 

Why were they even flying so close when we had that wondergun offshore?

Power issues aside (They are, actually, a concern), HEATING would also be a very serious problem. A shot from that would cause so much heat in the barrel that they'd have to give it time to cool off, otherwise we're talking missing the shot as a least dramatic possibility, and the rail gun outright exploding as a worst-case scenario.
