Mass Effect 3 Citadel Target Jamming Technology Quest Guide

24 September 2026 | 113

Navigating the sprawling Citadel in Mass Effect 3 often reveals valuable side assignments that directly contribute to the galactic war effort against the Reapers. One such quest, Citadel Target Jamming Technology, requires Commander Shepard to secure specialized Geth data to assist local security forces. This guide explains how to initiate the assignment, locate the necessary technology, and claim your rewards efficiently.

How to Unlock the Target Jamming Quest

To begin this assignment, players must first complete the Priority The Citadel 2 story mission. Once the Citadel becomes accessible again, travel to the Presidium Commons and make your way toward Apollo's Cafe.

Near the cafe area, you will find a Turian C-Sec officer examining a damaged console while speaking over his comm link. Approaching the officer and overhearing his discussion about defensive equipment automatically adds the objective to your journal.

Where to Find the Jamming Tower Data

The primary method to obtain the required data occurs during the main storyline mission Rannoch Admiral Koris. While navigating the AA Gun Control Facility, inspect the terminal situated on the right wall near the left anti-aircraft gun setup.

Interacting with this console allows you to download the Jamming Tower Data directly before leaving the planet. Securing the item during this mission ensures you complete the objective without spending additional credits.

Alternative Method via Spectre Requisitions

If you complete the Rannoch mission without retrieving the data, there is no need to worry about failing the quest. Players can simply visit the Spectre Requisitions terminal located in the Citadel Embassies area.

The terminal offers the Geth Target-Jamming Tech item for purchase at a cost of 1,000 credits. Buying the entry satisfies the quest requirement immediately, making it very convenient for players who missed the pickup.

Delivering the Tech and Quest Rewards

After acquiring the jamming data through either method, return to the Presidium Commons on the Citadel. Speak with the Turian C-Sec officer at Apollo's Cafe to hand over the technology.

Completing this assignment rewards Shepard with 30 Experience Points, 5 Reputation points, and 1,000 credits. Additionally, this effort boosts the Citadel Defense Force war asset by +8 points, aiding your overall military readiness for the final battle.
