The Long-Ranged Scanners will detect ship presence. This event can occur multiple times per sector.

The intro text for this event varies, and could be any of the following:

Although you were expecting the Rebels, you never imagined their fleet could have grown so fast. Your scanners can hardly register them all before a fighter stationed nearby moves in to attack.
This system is flooded with Rebel warships. Luckily your ship's signature is disguised as a civilian transport. Most heavy vessels ignore you but a small fighter is approaching with weapons hot!
You arrive to find a Rebel battalion encircling a nearby planet, launching landing parties. A small scout moves toward your position. Prepare for a fight!
As soon as you arrive you find yourself in the debris of a fierce battle. However, only Rebel warships remain and you find yourself immediately under attack.
Shots fly by and your computer registers multiple weapon locks as soon as you arrive. Evasive action!
What was once a great series of space stations is now nothing but a small ring of debris around the nearby moon. There's no time to mourn the dead; an enemy approaches!
The Federation seems to have put up a good fight. A number of Rebel ships lie broken or wounded. However their overwhelming numbers force the remaining Federation forces to retreat. Hopefully you can get away in time as well.
- Fight a Rebel ship. (no surrender offers, no escape attempts)
  - (After destroying enemy ship) There's no time to salvage all of the wreck, the fleet is still nearby. Get ready to jump!
    - You receive low scrap.
  - (After killing enemy crew) There isn't time to salvage the enemy ship but your crew made off with a few nearby materials. Prepare to jump.
    - You receive medium scrap with resources.
