Technical Data Hunting – Some Tips and data

fallout 76 discussion and inform - Technical Data Hunting - Some Tips and data

I still get the occasional message on the old post here so I thought I would re-post with all the new edits nicely formatted.

Technical Data is found in Round filing cabinets, cigar shaped bins and some desks (some have found in other containers, but I am unable confirm) , Once you have completed the Brotherhood of Steel mission "Forbidden Knowledge" you can turn in this data at the basement room of Camp Defiance, there is slot in the wall that you can use. There is XP, Caps and loot to be had, the more you submit the more XP and Caps you can get (This max's out at 4 pieces)

This was done on the PC, but no reason to think other platform rules are any different.

There is 3 types of Loot than can drop – BOS Shielded Underarmor plan, Apparel and Paint Plans. (Also some ammo, caps, XP and aid always drops).

BOS Shielded Underarmor Plan has a chance to drop – You need to learn the other BOS Underarmor plans bought from vendors before this starts to drop. This is a separate loot, and can drop in addition to the following.

User u/eckserah has done some data mining, the way the loot is calculated is it'll roll for apparel, if any of the apparel succeed it'll drop and stop and not for paint, if its unsuccessful, it will roll for paint. The data mining suggests that the type of paint drop is random, however the experience of everyone who has received paint strongly indicates it drops in the order set out below, and only after you have learned the previous rank.

Note – All % are based off 232 technical data submissions and rounded to nearest %point.

Aid and Ammo always drop

(equal chance of each)





+Random Ammo (sorry did not capture this)


31% Chance of Dropping one of the following items

Field Scribe Uniform -16%

Engineers Uniform – 25%

Bomber Jacket – 30%

Army Fatigues – 10%

Brotherhood Scribe Outfit – 6%

Science Scribe – 13%


6% Chance of Drop. Note, Starting with Knight, they drop in order, but only after you have learned previous rank. –

T-60 BOS Knight

T-60 BOS Knight Captain

T-60 BOS Knight Sergeant

T-60 BOS Knight Officer

T-60 BOS Paladin

T-60 BOS Elder

Note – Pieces of power armor when painted will have the labels of BOS, BOS II, BOS III, BOS IV, BOS V, BOS, BOS VII.

BOS Shielded Underarmor Plan

Currently unknown chance of this dropping.


There is also additionally a 13% chance of a Random 1* Piece of Max level Armour. (Strangely I never dropped a Right Arm).

Tech Data Locations

White Springs Bunker, military wing desks (26 in the room, plus one in the detention room)

AMS Watago (28 Desks and Filing Cabinets) The place is packed with turrets.

Robco Research Center (12 Filing Cabinets)

Sugar Grove (15 Filing Cabinets)

VTU (12 Filing Cabinets)

Watoga high school, (12 file cabinets and one safe.)

Chareston Herald (12 File Cabinets)

Monongah Power Plant (Approx 12 in power control room)

Thunder Mountain Power Plant (Approx 6)

Alpha/Brave/Charlie Silos Sites – (A lot, but a right pain to farm due to turrets, enemies, and distance you need to travel between submitting)


Tech Data Farming

When you load into the server the loot in each of these containers has a chance to be either tech data, ordinary loot or empty. Once you have looted the desk of anything it will not respawn loot again for about 72 hours (I've been unable to find exactly how long, there seems to be some rng on the time).

So to maximize your chances, look at each of the desks, if there is technical data then grab it, and submit it, if there is anything else, leave it, the next time you load into the server the loot changes with a chance of Tech Data.


They all have a chance for technical data, no info if increased difficulty increases the chances of tech data, but the loot rules are the same, if they don't have tech data loot, leave whats in and the loot re-rolls when you next load into the world

Notable Chest Locations

Flooded Trainyard – 5 safes

Harpers Ferry – 7 (2 needs some parkour)

Watoga Civic Center suites – 3

Lewisberg Cemetery – 4-5 Safes with some in town.

Pleasant Hills cemetery – 3 Safes

National Radio Astronomy Research Center – 3 Safes

Other Tactics

If you have a very patient friend who has not completed the Forbidden Knowledge quest they can stack, drop and sell tech data, they can farm much faster as they do need to submit the data everytime.

To transfer the data, trade

Things I don't know...

I don't know the actual refresh rate of containers, its not time, it seems to be a different mechanic based on how many containers have been looted, it seems only a certain % can be filled at anyone time, so to refill a looted one, you need to loot a different container before the other is refilled, the test data I have is that the toon looted the bunker, then did not loot anything else for 3 weeks, bunker desks did not refill after 3 weeks, they did refill after I started looting containers again.

I don't know if SPECIAL has anything to do with it, I have 12 luck and have not tested with anything else.

I don't know the % Chance of Technical data spawning in a container, I did not track this, if I had to guess I would say low, 10%-15%, an unlooted Whitesprings bunker has 22 containers and typically has 2-4 pieces of tech-data.

I don't know if submitting multiple pieces changes the chances, I tested 10 times with 2 bits, the % seemed the same.


If you are looking for a full set of paints and you have average luck you'll be aiming to submit around 120 pieces of techdata.


The final armor Paint, BOS Elder


Hope this helps, good luck out there.

Disclaimer – This is only one persons experience, yours will be different. If several people want to provide their data I'd be happy to compile to be more accurate, but even if we got and compiled 100 peoples data, yours will be different, there is so many rolls going on here the chances that anyone's experience will be identical are astronomically small.
