This is a Mass Effect 3 paper model, Normandy SR2 Star Ship, designed by ThunderChildFTC. There are Systems Aliance and Cerberus two versions for this star ship papercraft. The Normandy SR-2 is a starship that appears in Mass Effect 2, serving as the "successor" to the SR-1. The Illusive Man had Cerberus build the SR-2 for the newly revived Commander Shepard's team to aid them in their mission to stop the Collectors' galaxy-wide campaign of human abductions. This ship is the headquarters of the Lazarus Cell.
The ship is very similar to the Systems Alliance's SSV Normandy SR-1, having been based on the design layout of the original. The Normandy SR-2 has several key differences, the most significant being that it is almost twice the mass of the original. Cerberus also designed the ship with more crew-oriented comforts by including civilian-grade accommodations. The ship still retains the SSV Normandy SR-1's stealth characteristics. However, unlike the SR-1, the SR-2 cannot land on every planet - due to its increased mass - requiring shore parties to use a shuttle to get to a planet's surface.
