Secure the Airport is a simulation and strategy game on Roblox in which you become an airport security guard and inspect boarding passengers for weapons and other suspicious items. During each run, you'll encounter dangerous criminals and smugglers that can only be suppressed using powerful guns obtained by unlocking and equipping various Classes. Moreover, each Class also increases your Hit Points, helping you survive longer in every run.

In this guide, we will segregate all the currently obtainable Classes into S, A, B, and C tiers.

The Classes included under the S-tier will grant you one of the best weapons in the game along with high Hit Points. Using them, you can survive longest during each run.

To progress from mid- to end-game and survive each run for a longer duration, you can invest in A-tier Classes that are affordable and grant you good weapons with decent Hit Points. Here's a list of them all:

B-tier Classes will help you dominate the mid-game progression and learn the weapon mechanics faster. Here's a list of them all:

The C-tier Classes will help you learn the game mechanics with basic weapons and stats. Here's a list of them all:

Classes are special loadouts that provide you with different weapons and Hit Points. You can unlock and equip them to improve your survivability and combat abilities during runs.

Juggernaut is considered one of the best Classes in Secure the Airport. It provides 800 HP and comes equipped with the PKM as its primary weapon, making it highly effective for surviving longer runs.

Rookie is the best option for beginners since it is the default starter Class. It provides 100 HP and comes with the MP7A1 and 0.357 Magnum, allowing new players to learn the game's mechanics without spending money.
