GTA Online Kosatka Submarine Guide: Price, Upgrades and Is It Worth It

The Kosatka is the submarine every GTA Online player needs to run the Cayo Perico Heist, and it works as a mobile base, arms locker and planning room all in one. The base sub costs $2,200,000 from Warstock Cache & Carry, and a fully optioned one runs past $9,000,000. Here is exactly what you get at each price point, and whether it is still worth buying in 2026.

The essentials:

• Base price: $2,200,000, bought from the Warstock Cache & Carry website on your in-game phone
• Fully upgraded with every option and the Sparrow helicopter: roughly $9,000,000-$9,085,000
• Required to plan, prep and launch the entire Cayo Perico Heist, solo or with a crew of up to four
• Comes with a torpedo room, planning table, crew quarters and a moon pool that stores extra vehicles
• Key upgrades: Sonar Station, Weapon Workshop, Guided Missiles, and the Sparrow attack helicopter

Where to Buy the Kosatka and What It Costs

You will not find the Kosatka at a normal dealership. Open the in-game internet on your phone, go to Warstock Cache & Carry, and buy it directly from there like a Facility or a Bunker. The base submarine costs $2,200,000 and comes with none of the optional add-ons active, though the hull itself already has the planning room, the torpedo bay and the moon pool built in.

Every upgrade after that is optional, and you can add them at purchase or later from inside the sub. That flexibility matters if you are still building up cash: buy the bare-bones Kosatka to unlock the Cayo Perico Heist, then reinvest your first few payouts into the add-ons that matter most to you.

Every Kosatka Upgrade, Priced and Explained

Upgrade	Price	What it does
Sonar Station	$1,200,000	Sends you searching the coastline for hidden sonar caches worth up to $75,000 of loot per real-world day, on top of gold bars and other collectibles
Weapon Workshop	$350,000	Lets you customize Mk II weapons and buy special ammo without leaving the sub, essential if you plan to fight your way through a loud approach
Guided Missiles	$1,900,000	Adds a missile system you fire from the Bridge, useful for clearing patrol boats or aircraft around Cayo Perico before a run
Sparrow helicopter	$1,815,000	A light attack helicopter stored on the moon pool's upper landing pad, launched straight from the sub for fast scope-out flights or an aerial escape
Sparrow homing missiles	$240,000	Turns the Sparrow into a proper gunship, worth it if you already own the Guided Missiles upgrade and want air cover on the return trip
Interior style	Free to a few hundred thousand	Cosmetic only, changes the color scheme of the crew quarters and bridge, no gameplay effect

Stack every upgrade, including the priciest interior style, and the total lands somewhere between $9,000,000 and roughly $9,085,000, depending on which cosmetic finish you pick. Nothing here is required to complete the heist itself; the Sonar Station, Weapon Workshop and Sparrow are quality-of-life and income boosters layered on top of a submarine that already does its main job on day one.

Is the Kosatka Worth Buying in 2026?

Yes, and it is usually the best first heist purchase for a player who has not touched the Cayo Perico Heist yet. A full solo Tequila run with a maxed cocaine bag still nets in the range of $650,000-$675,000 after Pavel's cut and the fence fee, and a rare secondary target like the Pink Diamond can push a single run past $1,000,000. Compared to other GTA Online passive-income setups, it pays for its base price within a handful of runs, especially since the heist can be run entirely alone with no cut for other players.

Where you should be more selective is the upgrade list. The Weapon Workshop is worth grabbing early if you expect to fight, since Mk II customization on board saves a trip to your gunrunning Bunker. The Sonar Station is a slow-burn investment that rewards players who log in daily; skip it if you only play a few times a week. Guided Missiles and the Sparrow's homing missiles matter far less for a stealthy solo run than for a loud team approach, so newer players can usually leave both for later and put that money toward businesses that keep paying out between heists, like a nightclub or a bunker.

How the Kosatka Powers the Cayo Perico Heist

The Kosatka is not just a garage for the heist, it is the mission hub. Every stage runs from inside the sub:

• The planning table is where you launch the scope-out mission, choose your approach, and pick which prep missions to run.
• The wet sub bay lets you swim or dive straight onto Cayo Perico's shore during the scope-out and finale, one of several infiltration routes alongside parachuting in or riding the Sparrow.
• The moon pool stores a personal submersible (a Stromberg or Toreador) and, if purchased, the Avisa mini-sub and the Sparrow helicopter, all launched directly from the Kosatka without a trip to a garage.
• Crew quarters let you invite up to three other players into the planning stage for a bigger, faster payout, though a solo run still keeps 100 percent of the take.

Because prep missions can be completed solo, in an invite-only session, or with a full crew, the Kosatka is the one purchase that makes the Cayo Perico Heist genuinely playable without relying on randoms.

Tips for Getting the Most Out of Your Kosatka

• Buy the Weapon Workshop before your first loud run; restocking special ammo mid-heist from Ammu-Nation is slower and pulls you away from the objective.
• Check the Sonar Station daily even on days you are not running the heist. The caches refresh once per real day and stack up if ignored.
• Use the Sparrow for the scope-out mission itself. It is faster than swimming in through the wet sub and lets you mark points of interest across the whole island in one flight.
• If cash is tight, the base Kosatka plus the Weapon Workshop alone is enough to run efficient solo heists. Treat the rest as upgrades for once you are already making good money from the heist itself.
• Compare the Kosatka's payout against your other GTA Online businesses before deciding where to reinvest your next few million; a maxed-out sub competes well with anything short of a fully staffed Nightclub warehouse.

Kosatka vs Other Heist Headquarters

The Kosatka is not the only property that unlocks a heist line, and new players often ask which one to buy first. The Arcade unlocks The Doomsday Heist, which pays well but needs a full crew and a much bigger upfront investment in Facility research. The Kosatka is the cheaper entry point and the only heist HQ built around solo play from the ground up, which is why most guides recommend it before the Arcade or the Agency for a player still building capital.

Frequently Asked Questions

Can you sell the Kosatka once you own it? No. Like the Facility and the Arcade, the Kosatka cannot be sold or traded in once purchased, so treat the $2,200,000 base price as a permanent investment rather than something to flip later.

Do you need every upgrade to play the heist? No. The base submarine already includes the planning table, the wet sub bay and the moon pool. Every add-on covered above is optional and only improves comfort, firepower or passive income.

Is the Kosatka worth it if you only play solo? Yes, more than almost any other GTA Online property. It is the only heist HQ that lets one player plan, prep and finish the entire job without inviting anyone else into the session.

The Kosatka is one of the few big-ticket GTA Online purchases that pays for itself almost immediately. Buy the base sub, add the Weapon Workshop, and you already have everything you need to start clearing Cayo Perico on your own terms.
