Item #: SCP-5179
Object Class: Keter
Special Containment Procedures: Because of SCP-5179 place and location we are unable to contain SCP-5179but we are able to slow its repair. We can send missiles to SCP-5179 to destroy it but as of now our missiles are getting destroyed by SCP-5179.
Description: SCP-5179 is a large space station about 3 thousand light years from earth. SCP-5179 was discovered in 1989. Now SCP-5179 is in no way related to SCP-2399 they both have weapons yes! But SCP-2399 has antimatter based weapons while SCP-5179 has an unknown type of laser weapon. These types of laser weapons which were detected using a thermal camera have reached the maximum temperature of 13,000 kelvin. When it last shot its laser it had gotten damaged by the debris of the planet. Once it reaches a minimum of 65% completion it will shoot at the earth causing a XK-Class end of the world scenario. The last thing we know is that SCP-5179 has turrets on it. We know this because after we sent a couple missiles at SCP-5179. After a while the turrets had started to get more intelligent and started to shoot at our missiles making shooting at it useless. We still don't know how to stop its repair because our missiles keep getting shot at. Our high rank teams are researching a way to make it so our missiles won't get noticed by SCP-5179 turrets. Our research team will update the article as more information comes out.
Addendum: SCP-5179-A The following is a report of the first discovery of SCP-5179
