Supply Lines Mission GTA San Andreas – Easy Walkthrough, Best Route & Fuel Tips

The Supply Lines mission in Grand Theft Auto: San Andreas is considered one of the most frustrating missions players face in the game. In this mission, Carl Johnson (CJ) helps his friend Zero sabotage his rival Berkley’s delivery operation.

Unlike most missions in the game where players drive vehicles or use weapons directly, Supply Lines requires controlling a small RC Baron aircraft equipped with a machine gun. Using this remote controlled plane, players must locate and destroy several delivery couriers moving around San Fierro.

The mission becomes difficult due to the limited fuel gauge, tricky RC plane controls, and multiple moving targets spread throughout the city. If the RC Baron runs out of fuel or gets destroyed before completing the objectives, the mission fails and must be restarted.

The mission begins at Zero’s RC Shop located in the Garcia district of San Fierro, where Zero asks CJ to stop Berkley’s courier deliveries. After launching the RC Baron from the rooftop, players must destroy all delivery targets and safely return the plane to the rooftop.

Although the mission can feel difficult during the first few attempts, it becomes much easier when you understand the best route strategy, fuel saving techniques, and proper flying controls.

Quick Answer:

The easiest way to complete the Supply Lines mission in GTA San Andreas is to destroy the closest couriers first, fly the shortest routes across San Fierro, use short bursts of the RC Baron machine gun, and return to Zero’s rooftop before the fuel meter runs out.

What is the Supply Lines Mission in GTA San Andreas?

The Supply Lines mission in Grand Theft Auto: San Andreas, developed by Rockstar Games, is part of the series of missions given by Zero, a technology enthusiast who owns an RC shop in the Garcia district of San Fierro.

In this mission, CJ assists Zero in sabotaging the delivery operation of Berkley, Zero’s rival in the hobby business.

To stop Berkley’s deliveries, CJ launches a remote controlled aeroplane called the RC Baron from the rooftop of Zero’s RC Shop. The aircraft is equipped with a machine gun, allowing players to destroy Berkley’s couriers travelling around the city.

These couriers move through San Fierro in delivery vans and motorcycles, making them harder to track and eliminate.

The goal of the mission is to destroy all delivery couriers before they complete their routes and then safely return the RC Baron to the rooftop. Completing the mission rewards players with $5000 and allows the storyline to progress further.

Why the Supply Lines Mission is So Difficult?

Many players consider Supply Lines one of the worst missions in GTA San Andreas because of its unusual gameplay mechanics.

Limited Fuel Mechanics

The RC Baron aircraft has a limited fuel meter that decreases continuously while flying. If the fuel runs out before completing all objectives, the mission fails immediately.

Because of this limitation, players must carefully manage their flight path and avoid unnecessary flying across the city.

Difficult RC Plane Controls

Another challenge is the RC Baron’s control system. The aircraft’s small size and lightweight design make it more difficult to control than typical planes in the game.

Players often struggle with:

• Maintaining stable flight
• Turning the aircraft quickly
• Aiming the machine gun accurately

Multiple Moving Targets

The couriers in the mission are constantly moving through the streets of San Fierro. Players must chase them while flying the RC plane, making it harder to aim and destroy the targets quickly.

Combining these mechanics makes the mission challenging, especially for players attempting it for the first time.

Mission Location and Requirements

The Supply Lines mission takes place in San Fierro and is part of Zero’s mission chain.

The mission starts at Zero’s RC Shop in the Garcia district, where CJ meets Zero and learns about his rivalry with Berkley.

Before Supply Lines becomes available, players must complete the previous mission called Air Raid.

During Air Raid, CJ helps defend the RC shop from Berkley’s controlled aircraft using a minigun turret placed on the rooftop. Completing this mission unlocks Supply Lines and continues the storyline.

Once the mission begins, CJ launches the RC Baron aircraft from the rooftop and starts tracking Berkley’s couriers across San Fierro.

Supply Lines Mission Objectives

The Supply Lines mission includes two main objectives that must be completed before the fuel runs out.

Destroy Berkley’s Delivery Couriers

The first objective is to locate and destroy Berkley’s delivery couriers travelling around San Fierro.

To destroy them effectively:

• Target the closest courier first
• Fly slightly behind the vehicle
• Lower the plane for better aim
• Use short bursts of the machine gun
• Move quickly to the next target

Following the shortest route between couriers helps conserve fuel.

Return the RC Baron Safely

After eliminating all couriers, the final objective is to return the RC Baron to Zero’s rooftop.

Steps to land safely:

1. Turn the plane toward the RC shop immediately
2. Avoid unnecessary flying
3. Slow down when approaching the rooftop
4. Land the aircraft carefully

Once the RC Baron lands safely, the mission is completed.

Common Mistakes Players Make

Many players fail the mission due to small mistakes that waste fuel or time.

Attacking Distant Targets First

Flying across San Fierro early in the mission drains fuel quickly.

Flying Without a Plan

Random flying wastes time and fuel. Always plan the route before chasing targets.

Missing the Landing

Even after destroying all couriers, crashing while landing will fail the mission.

Rewards After Completing Supply Lines
