The Shield Calculator plans your shields: pick a vessel type, shield generator, upgrades and Specialized Crew, and see the shield capacity, recharge rate, warm-up, hit delay and how long the shield needs to recover. All values come from the server’s own configuration, so they match HWS, not vanilla Empyrion.
HWS Connect → Tools → Shield Calculator (NA players: /rn/tools/shield-calculator)
How to Use It
- Choose the Vessel type (BA, CV, SV, HV) and your Shield generator
- Enter how many shield upgrades (capacity extenders, recharge extenders, reactors, hull modifiers) and Specialized Crew you have; devices with a block limit show “Shared limit: used / max”
- Set the Starting shield charge (0% = shield fully down)
- Read Shield capacity, Recharge rate, Warm-up time, Delay after being hit, Charging time, Capacity per pentaxid and the Total recovery time with its chart
Shortcut: import a blueprint (or open one from your Local library, shared with the Structure Viewer) and the calculator fills in the vessel type, generator and devices for you.
Good to Know
- Use in-game measured recharge (on by default) uses timings measured in game: a startup delay and slower charging than the config says. Turn it off for the plain config values
- Ignore block limits allows extra devices and crew, e.g. for POI builds
- Charging times are estimates and don’t include server lag
- Free for everyone; you must be signed in, you don’t need to be online in game
