The wind hit my face as I pushed open a rusted hatch and froze — the tower was fuller of cannon and dust than the map suggested. I told myself this was a quick grab; five minutes later I was elbow-deep in crates, cursing at a stubborn weapon rack. If you want the Propeller Spear, you should know how the place smells and moves before you commit.
The research compound perches on a windswept spit — Propeller Spear location in Crimson Desert
You’ll find the Propeller Spear inside the Aeronautical Research Base, a POI in the southeast corner of Delesyia. The campus looks like someone left a flight school to rot; from the road you’ll spot several guard towers. The correct tower is the one with an active chimney—you can’t miss the smoke.

Where is the Propeller Spear located in Crimson Desert?
It’s inside a guard tower at the Aeronautical Research Base southeast of Delesyia. If you’re using the in-game map or a community resource on Steam or a YouTube walkthrough from channels that cover Pearl Abyss updates, set a pin on the base and follow the smoke stacks. I prefer cross-checking with IGN-style guides for screenshots when I’m unsure of a tower’s identity.
The stairs smell of oil and old gunpowder — How to find the Propeller Spear in Crimson Desert
Take the tower steps until you hit a small room full of cannons and loose cannonballs. The spear sits on a weapons rack around a central pillar; it’s not hidden in a chest, so sweep the visible racks first. Grab it before you loot everything else—containers tend to trigger patrols.

How do you upgrade the Propeller Spear to Kuku Propeller Spear?
You can use the base Propeller Spear as-is, but I always turn unique pickups into upgrade material unless they’re irreplaceable. The Kuku Propeller Spear requires the spear, a blueprint, and additional crafting parts found across Delesyia and other POIs. Players often trade tips on Discord and Reddit; I’ve followed a few creators who list exact material counts and where to farm blueprints.
The upgraded Kuku version deals more damage, stores more wind-wave charges, and shortens the cooldown. Think of the base spear as a sketch and the Kuku as the finished painting—worth the extra materials if you prefer a permanent tool over a one-time trophy.
Will the Propeller Spear break if used as a main weapon?
Yes. The Propeller Spear has fixed durability and will break if you make it your primary weapon. That fragility is why I recommend converting it into the Kuku upgrade, which gives you better durability and a more forgiving charge system. If you’re tight on resources, use it to farm enemies who drop the blueprint or sellable goods first, then craft the Kuku when you’ve saved enough.
The spear’s special move fires a wind wave forward that knocks back enemies after you charge it up to five times; there’s a five-second cooldown between uses. It’s satisfying in open combat but clumsy in tight quarters, so use the blast to separate groups or finish fleeing targets.
I like to cross-reference community maps, Steam discussions, and Pearl Abyss patch notes when a weapon’s spawn or stats feel inconsistent. If you’re chasing the spear specifically, mark the Aeronautical Research Base on your map, watch the smoke from the right tower, and move fast—guard patrols and respawns can steal the moment from you; are you willing to leave it behind?
