To protect Earth & other defenseless worlds.

The United Galaxy Space Force or UGSF is the military of Earth, and created AGAD to focus on the Galaga Conflict.



The UGSF was established in the year 2090 when Earth was about to reach it's saturation limit popultion wise. The Government was re-established to the United Galaxy. The United Galaxy created several military organizations under the command of one larger one. The United Galaxy Space Force. 30 years later the United Galaxy changed the name of the galaxy's citizen from Earthian, to Galaxian.

Project DragoonEdit

The UGSF soon found out that when their ships left the galaxy they would be immediatly attacked. The UG did some research and found out that the aliens were completely mechanical. They code named the alien race UIMS. (Unknown Intellectual Mechanized Species) Later on while monitoring UIMS activity they discovered an immense weapon known as the Canon-Seed in the Epsilon Eridanus Galaxy. They sent a strike-force to destroy the weapon which succeeded.

The Rising of GourbEdit

Space-Fortress Gourb was striking out against humanity for separating it from the original UIMS fleet. As part of it's revenge on humanity it was feeding off the gravity of the planet Kornious. The UG launched it's task force again and defeated Gourb. Causing it to fall into Kornious and release all it's absorbed gravity, and destroy Kornious.

The Galaga WarEdit

In 2279 the Galaga launched their first major attack on mankind. But the UG responded almost immediately launching several Galaxip, and Galaxy Ships. The Galaga were defeated.

The Three Month WarEdit

The Galaga returned with more powerful fighters. The UG responded by launching Gyaraku and P55 Attack Ships, who drove the enemy into retreat.

Project GaPlusEdit

The Galaga Legions trained their best pilots and made their most high-tech ships in history for another strike at mankind. The UGSF soon caught wind of "Project GaPlus(Galaga Plus)" and launched a few Ogre-Headers, along with a fusion of a Galaxip and Gyaraku. This combined force caused them Galaga-Plus to be defeated, and allowed peace in the galaxy for seven years.

Galaga War 4Edit

The UGSF started the creation of AGAD to focus on the Galaga Conflict. With Galaga activities rising just outside the Solar System, the UGSF launched four groups of Gyaraku fighters to seek and destroy all Galaga fighters, and launch an assault on Planet Galaga. The four fighter legions were successful and defeated the Galaga threat for several years afterwards.

Attack of the ZolgearEdit

The UGSF had been receiving information of several gravitational problems on the moon Zol. Several space-craft had been having trouble landing and taking off. But the cause was found. Zolgear. Zolgear is an animal type alien with abilities to control gravity. He and the rest of his species were moving in to wreak havock on Zol's mother-planet, Exia. But team Dragoon defeated him before he caused too much damage.

Operation: Star IxiomEdit

Year 2459: The Galaga, UIMS, Bosconians, as well as two other alien races known as the Battsura and Sadin have attacked the UG. But before long this massive war becomes a race to see who can reach stars Gaia and Ixiom first. The UGSF had to assemble a Team of the best fighters and pilots in existance. Team Gaia led by Roy Heinick. Roy Heinick and his team managed to reach Gaia and Ixiom first creating a fortification, and defeating the other species.



The UG Army is are the foot-soldiers of the UGSF. They're barely mentioned as most aliens have to be destroyed ship-to-ship.


The UG Air Force is maybe the best knwon UGSF sub-area. They build fighters and gunships for use in wars like the Galaga Conflict. AGAD mainly has it's fighters working under this umbrella


The UG Navy is probably the second best known UGSF organization in existence. They specialize in fighting cruiser to cruiser and launching the Air Force's fighters. AGAD has probes working in this category.
