Normandy SR-2

The Cerberus-made Normandy SR-2 is a starship that appears in Mass Effect 2. The SR-2 is provided to Shepard's team by Cerberus, and its leader, the Illusive Man, to assist in their mission to put an end to the Collectors' galaxy-wide campaign of human abductions. This ship is the headquarters of the Lazarus Cell.

Its design is similar to the Systems Alliance's SSV Normandy SR-1, the design being based on the original specifications. It differs from the original in that it is approximately twice its size, more human-centered in its design and, thanks to Cerberus' considerable funding, features extra civilian-grade comforts for its passengers. The ship still retains the SSV Normandy SR-1's stealth characteristics. Unlike the SR-1, the SR-2 cannot land on every planet—due to its increased mass—and thus shore parties must use a shuttle to get to the planet surface.

Deck 1: Captain's Cabin
The captain's deck is the topmost deck of the ship and is entirely comprised of the captain's quarters. It is located directly under the exterior pressure hull, earning the nickname "the loft" from the fitting yard workers. Aside from a bed, bathroom, office desk, and other standard furniture, the Captain's Cabin features a computer terminal for tracking progress on Achievements, another private terminal for monitoring basic information about squad-mates and receiving emails, a trophy case containing souvenirs from previous missions, a closet for modifying Shepard's casual attire and combat armor layout, and a sound system that can play tracks from the game's soundtrack.

There is also a display case for model ships, a large fish tank, and a "space hamster", purchasable on the Citadel. Fish for the tank can be purchased at various stores. The fish can die if not fed, although Kelly Chambers can feed the fish for Shepard if the Commander gives her permission when she asks. If the player imported a character from ME1, and the imported character ended the game with a successful romance, a picture of the romanced character also appears on Shepard's desk. The picture frame will lie face down if Shepard is currently involved with an onboard crew member. If the player found the N7 helmet in the Normandy Crash Site DLC, it will be displayed on Shepard's desk.

If Shepard completes any of the romantic subplots, the Commander can also use an intercom on the desk to call up their romantic interest, who will appear on the sofa and can sit on said sofa or lay on the bed with Shepard.

Deck 2: Combat Information Center


The command deck of the SR-2 is comprised of the ship's bridge, CIC (Combat Information Center), Research Labs, Armory, Conference/Communications Room and main airlock. As with the layout of the entire ship, the SR-2's bridge and CIC mirror that of the SR-1 except wider and longer in scale.

From the bridge Joker can pilot the ship while communicating with the ship's artificial intelligence, E.D.I. Shepard can also use a control panel next to Joker's seat to open and close the hull's heat shields. The CIC of the SR-2 is still centered around a large galaxy map which Shepard can use to plot the Normandy's next destination, and directly next to the map is a private terminal where Shepard can access electronic correspondences and review basic information about the crew. Yeoman Kelly Chambers is stationed at the galaxy map as well. In front of the galaxy map is the Normandy's status display, where ship upgrades that were applied are displayed.

Unique to the SR-2 are the Armory and the Research Lab situated behind the CIC. The lab on the ship's starboard side is stocked with state of the art lab equipment and includes a terminal where Shepard can spend raw materials to develop upgrades for the squad or the ship itself, as well as review existing upgrades. The SR-2's armory on the ship's port side displays acquired weapons and a terminal where Shepard can organize the crew's loadout. Professor Mordin Solus and Jacob Taylor can be found in the lab and armory respectively.

The Communications Room is situated between the Armory and Research Lab. The room is dominated by a large rectangular conference table where Shepard can hold briefings and discussions with the crew as well as communicate via hologram with the Illusive Man in real time thanks to the ship's quantum entanglement based communications array. The table retracts into the floor when a briefing with the Illusive Man is held.

Deck 3: Crew's Quarters
The third deck of the ship is where the crew spends most of their downtime. It includes Miranda Lawson's office, crew quarters, bathrooms, life support, a mess-room run by Mess Sergeant Gardner and the AI core. The medical facility run by Doctor Chakwas is also situated here, as well as the main battery, which is near the cryo pods. The deck is very similar in terms of layout to the original Normandy's 2nd deck. Garrus Vakarian, Miranda Lawson, Thane Krios, Samara and Legion can be found here; Garrus is in the Main Battery Room, Miranda is in her office opposite the Medical Bay, Thane is in Life Support, Samara is in Starboard Observation and Legion is in the AI Core. Port Observation may be for a character not yet available; otherwise, the room is inaccessible.

Should Commander Shepard accidentally enter the wrong bathroom, EDI will politely remind Shepard that his/her correct restroom is on the other side of the ship. The men's restroom is on the port side, whilst the women's is on the starboard.

Deck 4: Engineering
The fourth deck is the engineering deck and houses the ship's core, which is a large floating sphere powered by technology visibly different to the technology that powered the original Normandy. Jack can be found here on the lowest part of the ship down the stairs just outside Main Engineering, Grunt is found in the ship's Port Cargo Area, Tali'Zorah is located in the room housing the ship's core, manning a console just like on the first Normandy, and finally, if available, Zaeed is located in the Starboard Cargo Area, where a video surveillance monitor and trash compactor are also found. If Zaeed is not downloaded then the Cargo area is not accessible and there will be no red light on the door.

Deck 5: Hangar
The lowest deck is the hangar, where the Kodiak shuttle is stored, as well as a space for the future M57 Hammerhead tank. The hangar deck is not normally accessible to Shepard; it is shown when Shepard's team leaves the Normandy while the Reaper IFF device is being tested and is the setting for a fight against an Oculus. If any squad members die in the final mission, their coffins are shown in the hangar in the outro.

EDI
'"I always work at optimal capacity." '

EDI (pronounced 'E-D'), which stands for Enhanced Defense Intelligence, is the AI of the Normandy SR-2 and is represented by a holographic floating blue sphere at various terminals throughout the ship where she can provide basic information about the Normandy and Cerberus. EDI functions as the electronic warfare defense for the Normandy and because of the potential danger of a rogue AI, she has been given behavioral blocks and can't interface with the ship's systems.

The Illusive Man restricted Shepard's access to some of EDI's files and capabilities for unknown reasons, although EDI surmises that it's probably because he doesn't want Shepard to know everything about Cerberus just yet. It is only later in the game that Joker unrestricts EDI's access to the ship's full array of systems when the ship is boarded by Collectors and the entire crew is abducted. EDI reveals the Normandy SR-2 was built using technical diagrams of the SSV Normandy SR-1, which was built by the Alliance upon the encouragement of Cerberus. The SR-2 was assembled using parts bought from various vendors, and built by Cerberus in a remote area of the Voyager Cluster.

EDI also gains access to "Anti-Reaper Algorithms," later in the game. When pressed on this subject by Shepard as to how she could hope to combat beings millions of years more advanced, she reveals that she was in part designed by technology gained from Sovereign's remains and thus, at least partially, based on Reaper technology herself.

EDI is voiced by Tricia Helfer.

Systems
The Normandy SR-2 is equipped with many advanced systems, some carried over from the old Normandy SR-1. Over the course of the game, multiple upgrades can be researched for the Normandy SR-2. The weapon, armor, and shielding upgrades affect the success of the final mission- for each upgrade that is not purchased, one crew member will die during the approach to the Collector base.

Armament
Javelin Disruptor Torpedoes

Initially, the Normandy is armed with two Javelin disruptor torpedo launchers. The Javelin is an experimental close-assault weapon. It consists of a "rack" of two disposable disruptor torpedo tubes bolted or magnetically "slung" onto the ship's exterior armored hull. The torpedoes are fired on converging trajectories, and detonate in a precisely timed sequence that allows the dark energy emitted by their warheads to resonate. This magnifies the resulting space-time warp effects.

Thanix Cannon (Upgrade, Cost: 15000 Platinum)

The Thanix Magnetic-Hydrodynamic Weapon is a cannon similar to (and in fact designed in imitation of) the weapon used by Sovereign during its attack on the Citadel. It uses an electromagnetic field to shape and accelerate a stream of molten metal, which inflicts horrendous amounts of damage from not only the impact but also from the intense heat of the molten metal. The cannon fires a bright blue beam, very similar to the red trails seen firing from the tips of Sovereign's 'arms'.

This upgrade can be researched after Garrus is recruited, and takes the form of a retractable battery of cannons mounted beneath the Normandy's main hull. If the Thanix Cannons are installed, the Normandy SR-2 uses them to successfully destroy a Collector cruiser guarding the Collector Base shortly after passing through the Omega-4 mass relay. Otherwise, the Normandy will attack the enemy ship with its conventional weaponry at extremely close range, but will sustain severe damage as a result. Thane or Garrus may be impaled on a metal beam, resulting in their death.

Defenses
Multicore Shielding (Upgrade, Cost: 15000 Palladium)

Advanced kinetic barriers utilizing Cyclonic Barrier Technology (CBT) can be refitted to the Normandy SR-2. The CBT violently slaps aside rather than halting incoming linear force. By rotationally firing their mass effect field projectors, the ship creates rapidly oscillating kinetic barriers instead of static ones. Shooting through the CBT is like trying to shoot at a target inside a spinning ball. If an emitter is damaged, the CBT corrects to become a traditional shield array, a safety feature that makes it most effective during opening volleys.

Multicore shielding can be researched after recruiting Tali. The shields prove to be useful during the final mission as Joker maneuvers the ship through the debris field. Otherwise, collisions with debris may cause the ship's power core to overload and explode, killing Tali, Legion or Thane (depending on the team Shepard takes to fight the Oculus).

Heavy Ship Armor (Upgrade, Cost: 15000 Palladium)

Asari-designed Silaris heavy ship armor can be refitted to the hull of the ship, improving its survivability in combat. The armor can resist even the tremendous heat and kinetic energy of starship weapons. The armor is nearly unsurpassed in strength because its central material, carbon nanotube sheets woven with diamond Chemical Vapor Depostion, are crushed by mass effect fields into super-dense layers able to withstand extreme temperatures. That process also compensates for diamond's brittleness.

This upgrade can be researched after talking to Jacob and asking him about upgrades. If the armor is not installed, an Oculus energy beam may penetrate the Normandy's hull, instantly killing Jack.

Propulsion & Power
Antiproton Thrusters

The Normandy's main propulsion is provided by four large antiproton thrusters, with both aft and forward exhausts. Antiprotons are injected into a reaction chamber filled with hydrogen. The resulting matter-antimatter annihilation provides unmatched motive power. The exhaust of antiproton drives is measured in millions of degrees Celsius; any vessel caught behind them will melt like wax in a blowtorch.

Fusion Plant

Power for the Normandy's drive core and electrical systems is provided by a nuclear fusion plant.

Tantalus Drive Core

Integral to the Normandy’s stealth systems, the oversized Tantalus Drive Core generates mass concentrations that the Normandy "falls into", allowing it to move without the use of heat-emitting thrusters. It also generates the mass effect field around the ship that enables faster-than-light travel. The design is based on that of the Normandy's, but is slightly different, being vertically oriented relative to the ship instead of horizontally oriented.

Extended Fuel Cells (Upgrade, Cost: 3000 Element Zero)

The Heed Industries Helios Thruster Module propulsion system far outpaces the typical liquid hydrogen/liquid oxygen reactions that power a frigate's maneuvering thrusters. By using metastable metallic hydrogen, the Helios boasts a fuel that burns at far greater efficiency than liquid H2/O2. Navigators can execute the numerous small course corrections inherent to any long-distance travel without fear of exhausting the ship's fuel supplies. This net gain extends to forward impulse as well: a ship powered by antiprotons can coast temporarily using the Helios to reach an inferior but highly sustainable speed. Such efficiency lowers antiproton consumption, a constant concern for any warship. The same efficiency that allows for microburn course correction can power rapid bursts of motion. Once the pilot becomes used to the ship's new energetic responses, he can easily put the ship wherever and at whatever angle he desires.

Extended Fuel Cells increase the FTL fuel capacity of the Normandy SR-2 from 1000 to 1500. This upgrade can be researched after either Samara or Morinth is recruited.

Sensors & Scanning
Modular Probe Bay (Upgrade, Cost: 15000 Iridium)

The Modular Probe Bay doubles the maximum number of probes the Normandy SR-2 can hold from 30 to 60. It can be researched after recruiting Thane.

Advanced Mineral Scanner (Upgrade, Cost: 15000 Iridium)

The Argus Advanced Mineral Scanner delivers superior long-range topographical scanning resolution and rendering speed.

By deploying an orbital multistatic grid of 100 radar-emitting micro-satellites, the Argus quickly delivers a global Digital Elevation Model (DEM) at 15 meters per pixel (mpp) resolution, vastly outclassing the Normandy's previous scanner peak performance of 27 mpp. Such imaging quality provides superior defense intelligence, and at a speed warranted by the dangers of combat.

At slower scanning and rendering speed, the Argus can resolve down to an astonishing 0.001 millimeter per pixel—ideal for geological and biological prospecting, archaeological research, and long-term security surveillance. By employing such a massive multistatic grid of nearly-untraceable micro-emitters, the resilient Argus is virtually invulnerable to electronic countermeasures. The spherical geometry of the Argus grid also allows superior cross-sectioning of targets.

The Argus Advanced Mineral Scanner increases the rate at which the player can sweep the 'scanner' across a planet while searching for resources. It can be researched after talking to Miranda and asking her about upgrades.
 * It should be noted that, on the PC, this upgrade is poorly designed. Essentially, all it does is increase the player's mouse sensitivity while scanning. Regardless of whether or not this upgrade is installed, scanning can be made less tedious by manipulating mouse sensitivity outside of the game.

Other Systems
Stealth Systems

Along with the Tantalus Drive Core, the Normandy is able to temporarily sink its heat within the hull. Combined with refrigeration of the exterior hull, the ship can travel undetected for hours, or drift passively for days of covert observation. This is not without risk. The stored heat must eventually be radiated, or it will build to levels capable of cooking the crew alive. This stealth system apparently does not fool the scanners of Collector ships.

Med-Bay Upgrade (Upgrade, Cost: 50000 Platinum)

The medical bay of the Normandy SR-2 can be upgraded with a dermal regenerative unit, capable of removing Shepard's facial scarring regardless of paragon/renegade alignment. Dr. Chakwas sends a message to Shepard about this upgrade, and it can be researched in the Tech Lab.

Reaper IFF

The Reaper IFF (Identification Friend-Foe) is a piece of Reaper technology which allows safe passage through the Omega 4 mass relay, presumably by commanding the relay to use more accurate methods of mass effect corridor transit. The Reaper IFF is recovered by Shepard's squad upon the derelict Reaper orbiting Mnemosyne and integrated into the Normandy SR-2's systems.

When installed and activated, the Reaper IFF transmitted the location of the Normandy SR-2 and locked up its systems. The Collectors were able to ambush the Normandy, abducting most of the crew and forcing Joker to link EDI to the ship's main systems.
