P90
P90 an be found already onboard the Titan. You will receive an order to find G-46 hatch. Once you find the door to the room with this hatch, turn back and go to the room opposite. There you will find the gun on a box.
U-100 MK6
You can find this weapon on the Titan's upper deck, right after the cutscene where the ship breaks into halves and you jump with your team over to the other side. Right to your left, there are several holes to the lower decks. Jump down there, kill the enemy staying there and take the corridor to the left. The U-100 MK6 should be right in front of you leaning against a wall fragment.
SPAS-12
Once you get into the hangar, you should notice a white plane. Its back hatch should be open so, walk inside and pick up the SPAS-12 from the floor.
