Earth Space Defense

Earth Space Defense (ESD) is an international program that serves as Earth primary defense against future extraterrestrial threats. It was founded by President Thomas Whitmore, Steve Hiller, and David Levinson.

Foundation
Earth Space Defense was founded in Area 51 in 1997 by President Whitmore and War of 1996 heroes Steve Hiller and David Levinson. It was coinciding with political unity between Earth's nation. ESD began public recruitment and opening up the ESD Children Space Recruit and ESD Step Academy for the future generation. ESD was also tasked with reverse-engineering alien technology recovered from the war. This enhanced humanity capability in space, consumer, and military technology.

In 2000, United Kingdom became the first country to colonize on the moon. The next year France colonized Mars and China colonized Saturn's' moon Rhea. ESD is lead by Steve Hiller with David Levinson as Deputy Director. In 2007, War of 1996 hero Jimmy Wilder volunteered to pilot the first hybrid fighter which malfunctioned and killed him.

By 2015, ESD was almost globally and had set up a moon base on the moon and create Orbital Defense System. The regular transportation were moon tugs. Fighter jets were modernize into hybrids. Marine One was also outfitted with such a drive. Hybrid blaster were the most common weapon and developed cold fusion weapons.

War of 2016
ESD was informed of a alien arrival on the moon. The orders from President Elizabeth Langford, the Moon base destroyed the ship. During the 20th celebration, the aliens arrived and invaded Earth a second time. Both the moon base and Orbital Defense System were destroyed in the attack. The ESD later launched a retaliatory strike on the alien Queen which was a failure. ESD later came in contact with the Sphere, an alien AI that arrived to help humanity against the Harvesters. With the Sphere's knowledge, ESD plotted another attempt to bait the Queen. The ESD was successfully able to kill the Queen and end the invasion. This caused the Sphere to offer ESD the leadership of their Resistance against the Harvesters.
