The Normandy is a prototype starship, developed by the human Systems Alliance with the assistance of the Citadel Council. It is optimized for scouting and reconnaissance missions in unstable regions, using state-of-the-art stealth technology.
For most ships, the heat generated through standard operations is easily detectable against the absolute-zero background of space. The Normandy, however, is able to temporarily sink this 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.
Another component of the stealth system is the Normandy's revolutionary Tantalus drive, a mass effect core twice the standard size. The Tantalus drive generates mass concentrations that the Normandy "falls into", allowing it to move without the use of heat-emitting thrusters.

The SSV Normandy SR-1 was a prototype starship developed by the human Systems Alliance with assistance from the Citadel Council. The ship employed state-of-the-art stealth technology for reconnaissance in dangerous regions.
Most ships emit heat that is easy to detect against the absolute-zero background of space. The Normandy, however, could temporarily store its waste heat deep within the hull, allowing the ship to travel undetected for hours--or drift passively for days of covert observation. This was not without risk. Eventually, the stored heat had to be released, or it would build to levels that could cook the crew alive.
Another key component of the Normandy's stealth system was the revolutionary Tantalus drive, a mass effect core twice the size of a standard unit. The Tantalus drive generated mass concentrations that the Normandy "fell into," allowing it to move without the use of heat-emitting thrusters.
The Normandy SR-1 was destroyed in 2183 when it was ambushed by a Collector ship in the Omega Nebul
