	<htmltext>Why launch pizza and ice cream, which might not withstand the 5000 G acceleration when you can launch a bunch of cubesats or microsatellites.

In fact there's a microsatellite(it's name escapes me) up there that's a web server. If you have some amateur radio equipment you can download and upload files to it. It can't store much, only enough for about an email or so.

But with improvements in electronics it'll be possible to store even more data on a microsatellite. So eventually the Pirate Bay or Wikileaks or any other dubiously legal website might consider moving some of their servers 'to the stars.'</htmltext>

<sentencetext>A super cannon of this scale is unlikely to be useful to any non-superpower since the sheer scale of the device seriously limits its mobility.
Limited mobility means it would be easy for an enemy to take the device out, assuming the enemy has superior air power.So a weaponized version of this might benefit the US since they would be able to defend it, but for a country like Iran it would just be an expensive easy to hit target.</sentencetext>
