Operation D-Con

This mission begins with you fighting off various enemies in air-to-air combat, including two Aces, among which the Most Wanted members Lt. Rulon Raymond and Lt. Serozh Sarkisyan.

Follow the large ship by using your thrusters (press the left stick) and enter via the left side of the vessel. Destroy the enemies up front with your ship, exit and go through the hall. Clear the next room and go through the door.

Head up the steps and turn left first - there's an optional armory door here with an equipment upgrade. It also contains the Ballista EM3 Weapon.

Ballista EM3 Weapon

Use the console in the next room (after defeating the enemies), then move into the warhead assembly area. Kill the enemies and hack the armory in the far left back. 25 enemies will appear from the door you came from, so throw all your seekers in that direction, followed by your shock grenades, and hide behind the nearby pillar. From here, hack a bot and use it to take out as many enemies as possible. Clear the rest by yourself.

Inside the armory there's an equipment upgrade as well as the mission's objective; the Weapon sample.

Armory Operation D-Con

After this, simply head through the linear hallways and exit the ship safely.

Note: This will automatically add the Most Wanted member Vice Admiral Vlad Derhachov to your kills.
