EVE Frontier Catapult Planner

Yeet Planner is EF-Map's Catapult infrastructure planner for EVE Frontier. Give it an origin and a destination and it plans what to build or wake to get there: which hops use existing Stargates, where to place Mini Catapults, and where a Heavy Catapult is needed to bridge a long gap. It runs free in your browser as part of the EF-Map star map, no account required.

The output is an infrastructure plan, not a normal flyable route. Catapults are one-way, so Yeet Planner tells you what to prepare before you jump, in order, hop by hop.

Right-click systems while the Yeet Planner tab is active to add required waypoints or avoid systems. Waypoints are visited in added order by default, with an optional experimental nearest-neighbour ordering checkbox. Avoided systems cannot be used as stops, but their stars still count when Catapult interference is checked.

The button opens EF-Map with the Routing panel. Choose the Yeet Planner tab to start planning.

Mini Catapult vs Heavy Catapult

Catapults come in two tiers, and the planner picks the right tool per hop:

The Catapult interference rule, in plain language

A Catapult cannot fire past closer stars. EF-Map models it like this: draw a straight line from your star to the target star, and imagine a sphere sitting on that line whose diameter is exactly the line itself. If any other star is inside that sphere, the direct shot is blocked. If the sphere is empty and the target is within range, the shot is valid.

Blocked does not mean stuck. The star that blocks your line is itself a valid closer target, so Yeet Planner automatically searches for chains of valid hops and detours around interference for you.

What a plan gives you

• The full system sequence from origin to destination, drawn on the 3D map with curved Catapult arcs.
• Per-hop detail in the Route Systems window: Stargate, Mini Catapult, or Heavy Catapult, with distances and gate wake status.
• Summary counts: Stargate hops, Mini Catapult hops, Heavy Catapult hops, and total distance.
• Optimization modes: Prefer Stargates, Prefer Catapults (only use Stargates where no Catapult chain can cross), or Fewest Catapult Hops.
• Clear failure diagnostics when a plan is impossible with your selected tools, naming the exact gap that blocks it.
• Sharing: a link that reopens the plan in EF-Map, a text summary, a share-card image, and an in-game note with clickable system links.

Material totals are deliberately not shown because build and wake costs can change. The planner shows hop and build counts; players should evaluate construction and wake tradeoffs against current in-game costs.

How to open it

1. Open EF-Map with the Routing panel.
2. Choose the Yeet Planner tab (alongside Point to Point, Scout Optimizer, and Reachability).
3. Set origin and destination by typing system names or clicking stars on the map.
4. Add constraints by right-clicking stars for required waypoints or avoided systems. Remove them from the chips between Origin and Destination.
5. Calculate and review the infrastructure plan on the map and in the Route Systems window.
6. Share it with the crew that will build it.
