Ships that use a wormhole in honorverse, is effectively instanteous translocation, excepting the need to change from wedge to sails, enter hyper, and change back from sails back to wedge. In addition to the need to 'slowly' accelerate on both entry and exit, call it between 3 and 15 minutes on average to completely use a terminus, in peace time.
In Laocoon-II, we saw some destroyers popping through a terminus with surprise, and accelerating at 500+ gravities, when the 'normal' maximum speed is like 20-ish. That's in another book, which I can't recall but I should be getting close to, on my latest cycle through the books. AAC perhaps?
