Same VU seems really underpowered. What's the advantage there over a standard boarding? Certainly quite inferior to assault boats at that point.
I also don't consider a Lathe launch bay's magnetic pressurization field to be on the same "density" level as a void shield to prevent teleportation. The whole point of it is to keep the component pressurized with air to allow craft to enter/exit without having a physical hangar door. That field has no ablative effect to counter attacks, or even entry/exit, so I wouldn't say it interferes with teleporting like a void shield would.
