Inside, behind a locked door (Easy) to the right upon entering. In the northeeastern tent, first to the right when entering from the fast travel point, under the closest bed to the right after entering the tent. On top of a radio on the second floor of House #104. In the X-13 stealth testing lab, inside the Testing Area, found on the floor of the kitchen area, between the 2 fridges. In House #102 upstairs in the back room, on top of a black box. Look opposite the table with the toolbox, and it is between the lowest two items of equipment. Sandwiched in a rack of old world scientific equipment on the upstairs landing. In House #103, upstairs in a bedroom, on the shelf by the desk. The recipe is inside along with some random loot. When reached, look to the left to see a rectangular vent which can be opened by jumping toward it and activating it in mid-air. Go across the center bridge (the one with the toolbox and footlocker at the end).

Hidden inside the SW vent in the Reception Observation Area of the X-13 stealth testing lab. You must fire the fixed gun located at X-7a 'Left Field' first, however. From fast traveling to the location, head forward through fence, third crater on left with the footlocker near the NW corner of the area, after firing the artillery cannon at X-7a 'Left Field' Artillery Launch.

Inside a footlocker found in one of the small craters. In the Artillery Command Center, on the lip of the main console. Inside, on the very top catwalk, under the screen of a microfilm reader in the little piece of catwalk that juts out to the left.

On the ground to the right upon entering, underneath the bottom of the shelves, next to a piece of scrap electronics.
