[member="Cira"] The very IC event that motivated the Eri heavy long-range tractor beam, which I wanted second-chanced, proved the importance of having the mount of an Eri unit have some mobility in order to actually accomplish its intended role, that is, deviate planet-killing asteroids, and it also proved that platform mounts, even orbital, lacked the required mobility. For these reasons, I feel that restricting it to platform mounts will defeat the purpose of the device.
I can always reduce production level (to limited, maybe even semi-unique if warranted) but I will not yield on shipboard mounts because restricting the device to a platform mount, ground or orbital, will render it a lame duck.
As a result, it's a lot more cost-effective IC to mount it on capital ships than on orbital platforms. Given the above considerations, I feel it's unworkable unless some compromise can be reached that can allow the device to be mounted on ships as opposed to platforms only.
