Counts are for a monument with every spawn point filled. A spawner that holds one kind of crate gives an exact number; a mixed one picks a crate each time it spawns, so the count is an average and the last column gives its ceiling.
| Where | Count | Up to | Respawn |
|---|---|---|---|
| Arctic Research Base | about 3 | 6 | |
| Underwater Lab A | about 0.5 | 1 | 20 to 30 min |
| Underwater Lab B | about 0.5 | 1 | 15 to 30 min |
| Underwater Lab C | about 0.5 | 1 | 15 to 30 min |
| Underwater Lab D | about 0.5 | 1 | 15 to 30 min |
| Where | Each one holds | Layouts with it |
|---|---|---|
| Underwater Lab rooms | about 0.5 to 1.5 | 21 of 52 |
Across procedural Rust server maps, Underwater Lab Military Crate is a world loot prefab featuring 6 inventory slots (250 breakable durability) that draws from 109 possible item entries alongside 8 guaranteed Scrap across 6 monument and world spawner groups. Every drop row in the reference table above is compiled directly from the game's internal loot trees at build time to reflect vanilla survival rates.
In addition to per-item drop probabilities, stack size bounds, and spawn durability ranges, the Underwater Lab Military Crate sheet tracks expected container populations across every monument layout on the island. Solo players and clans can compare guaranteed Scrap and component returns per container open and plan monument routes around yellow, green, or red recyclers across the wipe.
Opening Underwater Lab Military Crate in Rust reveals 6 inventory slots drawn from 109 possible loot items plus 8 guaranteed Scrap on every open, with per-open odds, stack bounds, and durability ranges listed above.
Underwater Lab Military Crate (250 HP) spawns most heavily at Arctic Research Base (about 3), Underwater Lab A (about 0.5), Underwater Lab B (about 0.5) on procedural maps, with expected full-monument counts and minimum-to-maximum respawn timers recorded for every spawner group across the island.
Every Underwater Lab Military Crate opened in Rust grants 8 guaranteed Scrap alongside its 109 rolled loot entries, and any dropped components can be shredded at a monument recycler for additional Scrap.
Underwater Lab Military Crate carries 250 breakable hitpoints and must be smashed with melee weapons, tools, or projectiles before its 6 loot slots and any rolled Scrap spill onto the ground.
Monument spawners for Underwater Lab Military Crate run on preset minimum and maximum respawn timers (typically 15 to 60 minutes), and those timers tick down faster whenever more active players are connected to the server.
Each item percentage in the Underwater Lab Military Crate loot table shows the exact chance of receiving at least one stack of that item from a single open, calculated across all weighted sub-tables in the game files.
Firearms, tools, or armor pieces in the Underwater Lab Military Crate table that roll with partial condition show their exact durability percentage span next to their drop odds, whereas resources, Scrap, and components spawn intact.
