Given the limited range of one mile
Its letting what ever its shooting at well within a safe distance of the ship i.e. an aircraft would have already launched several weapons by then many miles away and scooted after all its no longer WWII and ground engagement with this weapon in unlikely as any commander taking his ship in that close to shore certainly has a death wish if only from canon fire.
Besides those small inconveniences it only shoots in direct line of sight so no overhead attacks or explosive decompression about the target then and whatever is behind the target be it friendly or not is likely to get some of the overspill too.
Yes I know its in beta phase but height seems to be the main advantage point for this weapon.
