How to look for records of... Research and development in the British Army
How can I view the records covered in this guide?
How many are online?
1. Why use this guide?
This guide provides a brief overview of records held by The National Archives that cover research, development and production of arms and other technologies by and on behalf of the British Army in the 19th and 20th centuries.
The records themselves are varied and extensive, with detailed written and visual information reflecting a broad range of topics, from reports from experimental artillery establishments to tank and small arms design. As well as successes, the records also document novel yet unsuccessful inventions.
2. Who created these records?
Although before the First World War technological development was – bar a small number of exceptions – largely the responsibility of the individual services, predominantly the Army and Navy, in 1915 the manufacture and supply of the materials of war were transferred to the newly created Ministry of Munitions.
While earlier records tend to be found within the War Office department, central direction of munitions development and production during the First World War and later periods means many also sit within other departments. The transfer of these responsibilities at different times has also meant records have been inherited and deposited by different departments, regardless of the date they were produced. As a result, you should consider broadening any search to include the series and departments given below.
3. Getting a search started and how to view documents
3.1 Speculative and basic keyword searches
This guide highlights some key series that you might like to explore. However, you may also wish to start with a more speculative keyword search of the whole of Discovery, our online catalogue. Consider the following kinds of keywords and search tips for searches:
- name of weapon/vehicle/equipment
- type of weapon/vehicle/equipment – be prepared to use broad as well as specific descriptions; some common examples include:
- ‘armoured fighting vehicles’ as well as ‘tanks’
- ‘small arms’ as well as ‘pistols’, ‘revolvers’ or ‘rifles’
- ‘artillery’ as well as ‘guns’
- very broad, general terms for military equipment and technological developments such as:
- name of invention or inventor (person and company)
3.2 Advanced searches and browsing
Use the advanced search in our catalogue to restrict your keyword search by:
- department code (see below for codes)
- date (allowing you to focus your search on an event or period of interest)
The department code you use will be determined partly by the dates that you are searching within and partly on the specific subject matter. Development of weapons and other technological military advances were originally the domain of the Ordnance Office and the British Army itself. For the majority of these early records use the following department code:
- WO (War Office)
After the start of the First World War, with the development of research establishments these responsibilities fell under various bodies. Therefore, for records from 1915 onwards use the following department codes (note that these departments also contain records that predate the parent organisations):
- MUN (Ministry of Munitions)
- SUPP (Ministry of Supply)
- AVIA (Ministry of Aviation)
- DSIR (Department of Scientific and Industrial Research)
- DEFE (Ministry of Defence)
View the full list of series and records in the above departments by clicking on the department code and selecting ‘Browse by reference’ at the foot of the page.
Read Discovery search help if you need more guidance on how to search and browse Discovery, our catalogue.
3.3 Viewing the documents
None of the records referred to in this guide can be viewed online. To view them you will either need to visit The National Archives or order digital or paper copies to be sent to you. You can order copies from Discovery by clicking on the record title (you should register an account in Discovery before you request copies).
4. Development and testing of armaments and military technologies
These are records of weapons, vehicles and other military technologies proposed, in development or undergoing trials. To browse or search in a series, click on the series reference.
4.1 Records of the Boards of Ordnance

6. Inventors and patents
Depending on the date, financial rewards for inventors were settled by the War Office, the Ordnance Council, the Ministry of Munitions and the Ministry of Supply. Records of these awards often provide blueprints and details concerning technological advancements, as well as correspondence regarding financial awards.
Search the records below of Royal Commissions, which were set up to deal with claims. The content of these large files varies a great deal. Some of it is information about someone’s claim to have invented something and the correspondence about the case; others contain blueprints and very specific details about the invention:
- the post-First World War Tomlin Commission in T 173 – search by inventor (personal name or company name) or invention
- the post-Second World War Cohen Commission in T 166 – search by inventor only (although an index and register of claims is available to help navigate the series)
- for more information, see our guide on Patents of inventions or
- consult the Design Registers in BT 45 (use the subject index in BT 46/9 (1843-1883) to help identify relevant records)
7. Records of production: factories and manufacturers
These are records predominantly of the interactions between industry (state-owned and private factories), the armed forces and government departments, and include:
- technical reports
