Mission Dialogue[]

Defeat Birds of Prey[]

Admiral Grigori Yanishev:

The Laurentian system is one the Federation's primary sources for quadratanium. Hundreds of people have settled at the Laurentian Colony because of the quadratanium industry.

Laurentian Outpost is here to defend those settlers and the quadratanium processing facilities. Unfortunately, we're close enough to the border of Klingon space to be an attractive target.

If the Birds-of-Prey get within range of our defense grid, we would have no problem taking them out ourselves. But that puts the colonists on the planet's surface at risk as well. I don't want it to get that far.

<rank>, I need you to hunt down some of the scouts and show them that the Federation is willing and able to defend itself.

Engage the Klingon Birds-of-Prey and stop them from reaching Laurentian Outpost.

Eliminate Cruisers[]

Admiral Grigori Yanishev:

It looks like the Klingons may be a bigger problem than we thought, <rank>.

The Birds-of-Prey were jamming our sensors. Now that they're gone, we're detecting Klingon Raptors and Vor'chas on an approach vector. If they attack the outpost, they could do some serious damage!

I know it's dangerous, but we need you to convince them to back off.

I advise you to form a task force with some of the other Federation ships in this area. You will need to use fleet maneuvers if you want to engage the Klingons successfully, but if you can take out some of their battleships, they may think twice about attacking the post.

Destroy the Raptors and Vor'chas before they can attack the outpost.

Eliminate Klingon Turrets[]

Admiral Grigori Yanishev:

This isn't a scout force, rank, it's an invasion!

I recognize the markings of some of the Raptors you defeated. They're from the KDF Seventh Fleet, under the command of General D'ald.

I've contacted Starfleet Command. They're calling in reinforcements, but as soon as they arrive the Klingons will know we're onto them.

The Klingons are creating a staging area in the asteroid belt. They're deploying disruptor cannons and weapons platforms, and they have tractored in a line of large asteroids to protect these fixed defenses.

If you sneak into their defensive line and take out enough turrets to open some holes in their defenses, we'll have an advantage when the real battle begins.

Eliminate Klingon satellite turret defenses in the larger asteroid belt.

Eliminate Battleships[]

Admiral Grigori Yanishev:

You've done a great job so far, <name>, but now it's time to take on some of the Klingons' heavy hitters.

The Klingons are moving in Negh'Vars. Those are their warships, and they're extremely dangerous. We need to disrupt their fleets before they can form up for an attack run.

Those warships are too powerful for a single ship to take on alone, so you and the other ship captains in the system will need to form battle groups to engage the Negh'Vars. Mass your fire and protect one another. I know you can challenge anything the Klingons can throw at us.

The Negh'Vars are massing behind the Klingons's defensive line. Good luck, <rank>.

Eliminate the Klingon Negh'Vars.

Destroy I.K.S. Kaarg and Escorts[]

Admiral Grigori Yanishev:

We've got a sensor lock on the Klingon fleet's flagship, <rank>, and it's trouble.

General D'ald's personal ship, the I.K.S. Kaarg, has entered the field of battle. It's taking a fixed position behind their defensive line, and the Klingons are setting up a series of communications relays encircling it.

This is it, <rank>. General D'ald has powerful allies in the empire, and he will be able to call in more ships to support him. But even Klingons will withdraw from battle when the costs are too great.

If you can defeat the Kaarg, you can end this fight!

You'll need to work with the other captains. I strongly recommend you do not attack General D'ald without support.


Admiral Grigori Yanishev:

Well fought, Captain! You and the other ships of your battle group are to be commended!

Turning in mission:

Admiral Grigori Yanishev:

Well done. You and the crew of the <ship name> should be commended for your actions today.
