Current profile: the latest value tracker describes S-Tank Railgun as a tank with two large cannons for ground threats and a railgun on top that can remove roughly 75% of an AI carrier's Health. The Wiki lists the same core weapons as Railgun + Mega Cannons.

What is S-Tank Railgun?

S-Tank Railgun is the Exotic variant of Military Tycoon's three-vehicle S-Tank family. The family also includes the Epic S-Tank Barrage and Legendary S-Tank Gatling.

The S-Tanks arrived during the BF-109 / Super-Tank Crate update on the November 23–24, 2024 weekend. The Railgun version was the rarest and strongest variant in the original crate family.

Railgun

The primary weapon is a charge-up Railgun. The Wiki says it takes a few seconds to charge before firing and deals decent damage.

Unlike Boss Sea Tank or Boss Viper, the S-Tank Railgun does not have rapid-fire railgun behavior. That makes each shot more deliberate and increases the penalty for missing.

How strong is the railgun?

The current market tracker says the railgun can take out roughly 75% of an AI carrier's Health.

That does not mean every target loses exactly 75%; it is a practical tracker reference showing that the railgun is the defining damage feature of this S-Tank variant.

Twin Mega Cannons

The secondary weapon is a pair of Mega Cannons.

The Wiki describes them as two large cannon shots that perform well against weaker ground vehicles but can struggle against stronger armor.

Special upgrades

The Wiki lists two progression upgrades:

  • Level 25: Railgun upgrade;
  • Level 50: Cannon upgrade.

The exact numerical effect is not fully documented on the current Wiki page, so this guide does not invent a percentage bonus.

Base stats

The Military Tycoon Wiki lists:

  • Base Speed: 32;
  • Base Health: 13.9K;
  • Total Base Damage: 16.8K;
  • Vehicle Type: Ground Vehicle;
  • Vehicle Class: Tank;
  • Passenger Seats: none.

Original crate odds

The original S-Tank event had several crate routes. The Wiki lists:

  • Super-Tank / Robux Crate: about 3% for S-Tank Railgun, costing 999 Robux;
  • Legendary Crate: about 6% random S-Tank chance, costing 9.5K Gems;
  • Epic Crate: about 2% random S-Tank chance, costing 2.5K Gems.

Because the Gem crates could return a random S-Tank rather than guaranteeing the Railgun version, the practical acquisition grind was worse than the raw percentage alone suggests.

What the supplied stat card shows

Your screenshot confirms:

  • Name: S-Tank Railgun;
  • Rarity: Exotic;
  • Class: Tank;
  • Damage: moderate;
  • Health: low-to-moderate;
  • Speed: high on the simplified card;
  • lower indicator: 95.5 / 6000;
  • RAP: 69K.

The lower 95.5/6000 indicator is visible but not labeled, so this guide leaves it unnamed.

Why Railgun is much more expensive

The current price gap is large: S-Tank Railgun trades around 30K–40K, while Gatling and Barrage are still in the single-digit thousands.

The Railgun version was the rarest original crate variant and remains the highest-rarity S-Tank. That scarcity premium matters even though its current Demand is only 2/10.

How to use S-Tank Railgun in PvP

1. Make the railgun shot count

The charge-up and lack of rapid fire mean missed shots cost time. Fire when you have a clear target instead of trying to spam the railgun.

2. Use Mega Cannons between railgun opportunities

The cannons give you something to use against ground vehicles while preparing or repositioning for another railgun shot.

3. Avoid relying on it as dedicated anti-air

The S-Tank Gatling has the more obvious air-defense role. S-Tank Railgun is better treated as a heavy precision ground-threat variant.

4. Unlock the Level 25 and 50 upgrades

The Wiki specifically says the tank needs its two special upgrades to reach full potential.

5. Use its mobility

The Wiki describes S-Tank Railgun as having decent mobility and turning rate for its class, so reposition instead of staying stationary after each railgun shot.

Current S-Tank Railgun value

The latest market tracker lists S-Tank Railgun at approximately 30K–40K Gems.

  • Demand: 2/10;
  • Scarcity: 5/10;
  • Functionality: 4/10;
  • Trend: Stable;
  • Suggested rarity: Exotic;
  • Collector Item: No;
  • Tradable: Yes;
  • Special: No.

What does RAP 69K mean?

The supplied screenshot shows RAP 69K. That is substantially above the current 30K–40K tracked Gem range.

For a normal copy, the fresh tracker is therefore more useful than assuming 69K is the current market price.

Trading note: current Demand is only 2/10. RAP 69K is well above the current 40K Gem High, so pricing purely from RAP can make the item difficult to move.

Community tier position

A current all-item community tier list places S-Tank Railgun in C tier for gameplay quality. That is player opinion rather than an official ranking, but it fits the current Functionality 4/10 score: useful and distinctive, but not a top meta vehicle.

Is S-Tank Railgun worth keeping?

For gameplay, it is worth keeping if you enjoy charge-up precision weapons and ground combat. The railgun gives it a playstyle the other two S-Tanks do not have.

For trading, the Exotic rarity and 30K–40K value are positive, but Demand 2/10 means finding the right buyer can take time.
