if Medium (aka Normal) mode is available to you by default (aka you see it greyed out by default when you first click on the map), then yes, you can clear E-3 on Medium for the Catapult.

Note though that ships tagged already with E-1 and E-2 colour tags cannot be used in E-3 for Medium difficulty.
