2553 Earth-Sanghelios Technology Exchange Program

After the events of 2552, both the Sangheili and the UNSC were in conditions that were less than optimal. Almost all of their colonies glassed, billions destroyed, their own homeworld devastated just short of glassing, and both their naval and planetary forces decimated, the UNSC quickly realised that they could not afford to fight another war on the same scale, not as they were. To remedy this, they proposed a technological exchange program with the Sangheili. Though initially quick to reject this offer, the Sangheili were reminded that without the Prophets, they had also lost the knowledge to build and easily maintain their own warships and equipment, and that the number of Huragok who had ended up on their side of the Orion Arm was woefully inadequate for the task. In exchange for technological assets, such as advanced Covenant directed energy weapons and shield technology, as well as first chance to salvage high priority salvage targets, the UNSC offered to assist in the maintenance and repair of the Sangheili warships. Signed by Fleet Admiral Brian Rawiri and Supreme Commander Orna 'Fulsam in 2553 on the Martian Naval Shipyards in 2553, the Exchange would dominate Human-Sangheili relations for the next two decades.
